In order to make it easier for you, the review committee, to understand the content of the present invention and the effects that can be achieved, the specific embodiments listed in the drawings are described in detail as follows: Please refer to Figure 1, which is the audio frequency adjustment device of the present invention. Module connection diagram. As shown in the figure, the present invention is mainly composed of an audio processing module 10, a radio module 20 and a speaker 30. The audio processing module 10 may specifically be a central processing unit or other data processing device. When the user's hearing is damaged due to degradation of physiological functions or trauma, disease, congenital defects, etc. In this case, there will be a problem that some audio or audio sections (hereinafter collectively referred to as audio) cannot be heard clearly. Therefore, a test audio model 40 is usually formed by testing specific audio that the user cannot hear or hear clearly. , and the test audio model 40 can usually have at least one bandwidth data 41, the bandwidth data 41 refers to the audio range that the user can hear, and when the test audio model 40 When there are more than two such bandwidth data 41, it can be determined that there are some specific audio frequencies that cannot be heard in the normal audio frequency range that the user can hear, causing a blocked area (that is, the specific audio frequency that cannot be heard) to appear in the continuous curve, and then Be divided into two or more bandwidth data41.

When the audio processing module 10 is configured with the test audio model 40, the audio processing module 10 can obtain at least one of the bandwidth data 41 from the test audio model 40, and based on the bandwidth data 41 in a Set the occupied bandwidth state in the audio range 11 to perform a bandwidth adjustment operation to generate an adjusted audio model 12. When the audio processing module 10 performs the bandwidth adjustment operation, it can generate an expanded or compressed audio model. The adjusted audio model 12, or the expanded and compressed adjusted audio model 12, the set audio range 11 is the audio frequency range set by the designer, more specifically, the audio frequency range that normal people can hear is 20Hz to 20000Hz, it can be used to test the user's hearing condition to build the test audio model 40, and the set audio range 11 is the audio range that the designer wants to adjust the user to hear, which can be the normal audio range. The range of 20Hz to 20000Hz can also be, for example, the range of 30Hz to 19000Hz. The range is not limited, and the adjusted audio model 12 is generated by, for example, expanding or compressing the specific audio that the user cannot hear originally. Audio model. Among them, the bandwidth adjustment operation will be explained in detail in the following paragraphs.

The radio module 20 may be a microphone or other related device that can receive external sounds. The radio module 20 here is connected to the audio processing module 10 so that when the radio module 20 receives external sounds from the external environment, When receiving a sound signal 21, the sound receiving module 20 can transmit the sound signal 21 to the audio processing module 10, and when the audio processing module 10 receives the sound signal 21, the audio processing module 10. Then the sound signal 21 can be processed according to the generated adjusted audio model 12, and an output sound signal 13 can be generated. More specifically, since the audio curve in the adjusted audio model 12 is generated through compression or expansion processing, it is assumed that the user cannot listen to the 1600hz audio, When the radio module 20 receives the audio signal 21 and the audio processing module 10 determines that the audio frequency in the audio signal 21 is 1600 Hz, the expanded adjusted audio model 12 is to expand the audio frequency originally at 1200 Hz. to the audio frequency range of 1600Hz. Therefore, if the sound signal 21 is a sound with an audio frequency of 1600Hz, the audio processing module 10 will adjust the audio model 12 according to the audio signal 21 to generate the output through the audio frequency of 1200Hz. Sound signal 13 (that is, the audio processing module 10 can generate the output sound signal 13 by compressing the 1600Hz audio frequency in the sound signal 21 through the 1200Hz audio frequency). Therefore, when the 1600Hz sound signal 21 is compressed, When the output sound signal 13 is generated, the output sound signal 13 will be processed to be lower than the original frequency (that is, the sound signal 21 with the original frequency of 1600Hz will be processed to output the output sound signal 13 with an audio frequency equal to 1200Hz. ) sound source.

Here, in order to facilitate the user to listen to inaudible audio and relatively provide a sound source from which the user can listen to real audio, in this embodiment, the present invention further provides the audio processing module 10 to determine the audio signal 21 In an audio manner, the sound signal 21 is selectively processed according to the test audio model 40 or the adjusted audio model 12 . Specifically, when the sound receiving module 20 receives the sound signal 21, the audio processing module 10 can first determine an audio in the sound signal 21 and determine the range that the audio falls into. Assume that the audio is 2000Hz, and the bandwidth data 41 of the test audio model 40 ranges from 60Hz to 15000Hz, the audio processing module 10 can determine that the audio frequency of the sound signal 21 is the sound signal 21 that the user can originally listen to. , therefore, the audio processing module 10 can choose to process the audio signal 21 according to the test audio model 40 to generate the output audio signal 13, but assuming that the audio frequency is 60Hz, and the bandwidth data 41 range of the test audio model 40 When the frequency is 100Hz to 18000Hz, since the audio frequency of the audio signal 21 falls into the audio frequency range that the user cannot hear, the audio processing module 10 can determine that the audio signal 21 of the audio frequency is the sound that the user cannot hear. Signal 21, enter The sound signal 21 is compressed and processed according to, for example, the expanded adjusted audio model 12 to generate the output sound signal 13 .

The speaker 30 can receive the output sound signal 13 by being connected to the audio processing module 10 and output the output sound signal 13 for the user to listen to. This effectively allows the user to listen to the sound signal 21 in the set audio range 11 .

Please refer to Figures 2 to 5 again, which are schematic curve diagrams of the test audio model before expanding the bandwidth data, the curve schematic diagram of the adjusted audio model after expanding the bandwidth data, and the test audio model before compressing the bandwidth data according to the present invention. The curve diagram of , and the curve diagram of the adjusted audio model after compressing the bandwidth data. As shown in the figure, when the audio processing module 10 obtains a bandwidth data 41 from the test audio model 40, the audio processing module 10 can occupy the set audio range 11 according to the bandwidth data 41. The bandwidth adjustment operation is performed in the bandwidth state. Assume that the set audio frequency range 11 is 20Hz to 19000Hz, and the bandwidth data 41 ranges from 20Hz to 16000Hz. The occupancy of the bandwidth data 41 in the set audio range 11 The bandwidth status can be represented by a bandwidth occupied range 411 and a bandwidth unoccupied range 412, that is, the bandwidth occupied range 411 is the 20Hz to 16000Hz occupied by the bandwidth data 41 corresponding to the set audio range 11 , and the bandwidth not occupied by the range 412 is 16000Hz to 19000Hz. Therefore, when the audio processing module 10 obtains the unoccupied bandwidth range 412, the audio processing module 10 can expand the bandwidth data 41 according to the range of 16000Hz to 19000Hz represented by the unoccupied bandwidth range 412. , thereby causing the bandwidth occupation range 411 to be adjusted to a range equal to the set audio range 11 (20Hz to 19000Hz). Thereafter, the audio processing module 10 can generate the expanded bandwidth data 41 based on the expanded bandwidth data. The tuning audio model 12.

In one embodiment, assuming that the set audio range 11 is set to 20 Hz to 15000 Hz, and the bandwidth data 41 ranges from 20 Hz to 16000 Hz, the bandwidth data 41 is in the setting range. The occupied bandwidth state in the audio frequency range 11 can be represented by a bandwidth occupied range 411 and a bandwidth exceeding range 413 in the bandwidth occupied range 411 that exceeds the set audio frequency range 11, that is, the bandwidth occupied range 411 is The bandwidth data 41 corresponds to 20 Hz to 15000 Hz occupied by the set audio frequency range 11, and the bandwidth outside the range 413 is 15000 Hz to 16000 Hz. Therefore, when the audio processing module 10 obtains that the bandwidth exceeds the range 413, the audio processing module 10 can compress the bandwidth data 41 according to the range of 15000Hz to 16000Hz represented by the bandwidth exceeding the range 413, so that The range of the bandwidth data 41 is adjusted to a range equal to the set audio range 11 (20Hz to 15000Hz). Thereafter, the audio processing module 10 can generate the compressed audio frequency based on the compressed bandwidth data 41. Adjust audio model 12.

Please refer to Figures 6 to 9 again, which are schematic curve diagrams of the test audio model before the two bandwidth data are expanded, the curve schematic diagram of the adjusted audio model after the two bandwidth data are expanded, and the two frequency bandwidth data of the present invention. The curve diagram of the test audio model before expansion and compression of the wide data, and the curve diagram of the adjusted audio model after expansion and compression of the two bandwidth data. As shown in the figure, when the audio processing module 10 obtains a plurality of bandwidth data 41 from the test audio model 40, the audio processing module 10 can operate in the set audio range according to each bandwidth data 41. The bandwidth adjustment operation is performed in the bandwidth state occupied in 11. Assume that the set audio range 11 is from 20Hz to 20000Hz, and one of the bandwidth data 41 ranges from 20Hz to 8000Hz, and the other bandwidth data 41 is from 20Hz to 8000Hz. When the range is 9000Hz to 20000Hz, the occupied bandwidth status of the plurality of bandwidth data 41 in the set audio range 11 can be represented by a plurality of bandwidth occupied ranges 411 and an unoccupied bandwidth range 412, that is, a plurality of the bandwidth occupied ranges 412. The bandwidth occupied range 411 is 20Hz to 8000Hz and 9000Hz to 20000Hz occupied by the bandwidth data 41 corresponding to the set audio range 11, while the unoccupied range 412 of the bandwidth is 8000Hz to 9000Hz. Therefore, when the audio processing module 10 obtains the unoccupied bandwidth range 412, the audio processing module 10 can expand a plurality of the bandwidth according to the range of 8000Hz to 9000Hz represented by the unoccupied bandwidth range 412. Capital Material 41, so that a plurality of the bandwidth occupancy ranges 411 are expanded to fill the unoccupied range 412 of the bandwidth, and the plurality of the bandwidth occupancy ranges 411 will form a combined bandwidth occupancy range 414 after expansion, so a plurality of the bandwidth occupancy ranges 411 will be formed. The combined bandwidth occupancy range 414 formed by combining the bandwidth data 41 can be equal to the set audio range 11 (20Hz to 20000Hz), and the audio processing module 10 can generate expansion according to the expanded plurality of bandwidth data 41 After that adjust the audio model 12.

In one embodiment, assuming that the set audio frequency range 11 is 20Hz to 16000Hz, and one of the bandwidth data 41 ranges from 20Hz to 8000Hz, and the other bandwidth data 41 ranges from 9000Hz to 18000Hz, The occupied bandwidth status of the plurality of bandwidth data 41 in the set audio range 11 can be composed of a plurality of bandwidth occupied ranges 411, at least one unoccupied bandwidth range 412, and the bandwidth occupied range 411 exceeds the set audio range. A bandwidth of 11 is represented by exceeding the range 413, that is, the bandwidth occupied by the range 411 is the 20Hz to 8000Hz and 9000Hz to 18000Hz occupied by the bandwidth data 41 corresponding to the set audio range 11. This bandwidth is not occupied. The range 412 is 8000Hz to 9000Hz and the bandwidth beyond the range 413 is 16000Hz to 18000Hz. Therefore, when the audio processing module 10 obtains that the bandwidth exceeds the range 413 and the bandwidth does not occupy the range 412, the audio processing module 10 can range from 16000 Hz to 18000 Hz according to the bandwidth exceeding the range 413. Compress the bandwidth data 41 beyond the set audio frequency range 11, and expand a plurality of the bandwidth data 41 according to the range of 8000Hz to 9000Hz represented by the unoccupied bandwidth range 412 to fill the unoccupied bandwidth range 412, and After expansion, a plurality of the bandwidth occupancy ranges 411 will form a combined bandwidth occupancy range 414, so the combined bandwidth occupancy range 414 formed by combining a plurality of the bandwidth data 41 can be consistent with the set audio range 11 ( 20Hz to 16000Hz), the audio processing module 10 can generate the compressed and expanded adjusted audio model 12 based on the compressed and expanded plurality of bandwidth data 41 .

In addition, when the audio processing module 10 performs an expansion operation on a plurality of the bandwidth data 41 During operation, the audio processing module 10 can expand each bandwidth data 41 according to an equal proportion according to the bandwidth occupancy range 411 occupied by each bandwidth data 41, or the audio processing module 10 can expand the bandwidth data 41 according to an equal proportion. The bandwidth data is expanded by an amount of 41.

For example, when the audio processing module 10 expands each bandwidth data 41 in an equal proportion according to the bandwidth occupation range 411 occupied by each bandwidth data 41, if the frequency of the bandwidth data 41 is When the wide occupancy range 411 is 1000Hz to 6000Hz, and the bandwidth occupancy range 411 of another bandwidth data 41 is 7000Hz to 17000Hz, the expansion ratio can be 1:2, that is, when a plurality of the bandwidth data 41 When it is necessary to fill in the unoccupied range 412 of the bandwidth of 6000Hz to 7000Hz through expansion, the audio processing module 10 can expand the bandwidth data 41 of 1000Hz to 6000Hz into the bandwidth of 1000Hz to 6333Hz according to its expansion ratio. Occupying the range 411, the bandwidth data 41 of 7000Hz to 17000Hz can be expanded to the bandwidth occupying range 411 of 6333Hz to 17000Hz, whereby the audio processing module 10 can expand each bandwidth in an equal proportion. Information 41.

But when the audio processing module 10 expands each bandwidth data 41 according to the same expansion amount, the unoccupied range 412 of the bandwidth from 6000Hz to 7000Hz is equally divided into each bandwidth data 41, so that the unoccupied range 412 of the bandwidth from 1000Hz to 6000Hz is The bandwidth data 41 and the bandwidth data 41 from 7000Hz to 17000Hz are both expanded by an expansion amount of 500Hz, thereby expanding the bandwidth data 41 from 1000Hz to 6000Hz into a bandwidth occupying range 411 from 1000Hz to 6500Hz, and 7000Hz The bandwidth data 41 to 17000Hz can be extended to the bandwidth occupation range 411 of 6500Hz to 17000Hz.
