Abstract

PURPOSE:To realize miniaturization and light weight by using a recorded optional sound as a notice tone at calling operation, attaining a setting change of the notice tone into a content or a tone or the like required by the user itself and further eliminating the need for a message display section. CONSTITUTION:With a recording switch 135 operated, a decoder 105 sends a signal to a digital recording and reproducing circuit 110, and the circuit 110 receiving the signal starts recording for a prescribed time. An optional sound inputted from a microphone 111 is amplified electrically at a microphone amplifier 112 and the amplified signal is inputted to the digital recording and reproducing circuit 110, in which the signal is further converted into a digital signal and stored to a memory area for number N of a message number (in this case for number 0) of a memory 113 as digital information. The notice tone is devised that its setting is revised into a content or a tone or the like required by the user itself and further a message display device is not required.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wireless selective calling receiver, and in particular, when receiving its own selective calling number, it plays back any pre-recorded digital sound. The present invention relates to a wireless selective calling receiver that notifies a carrier of the presence of a call by doing so.

[Prior Art] Conventionally, when this type of radio selective calling receiver receives its own selective calling number and message information, it notifies the carrier of the call by a series or continuation of tones or a melody sound. At the same time, message information was displayed using characters, symbols, etc. on a display unit such as a liquid crystal display.

Recently, a method has been proposed in which a memory for storing a predetermined sound is provided and the content of the call is announced by emitting the contents of this memory as sound from a speaker (for example, Japanese Patent Publication No. 63-5931 issue)
.

[Problems to be Solved by the Invention] However, the above-described conventional radio selective calling receiver has the following drawbacks.

That is, in a receiver that uses the former tone or melody sound, it is necessary to provide a display device to transmit the content of the received message.

This not only impedes the demand for smaller and lighter radio selective calling receivers, but also has the drawback that the user must always look at the display in order to know the contents of the message.

Furthermore, in the receiver of the S person, usable tones, melodies, or voices are input in advance into the receiver. Therefore, changing the tone intermittent cycle or frequency, changing the melody, or changing the audio content must be done by rewriting the memory contents with a special device or by replacing the memory itself. It was difficult for the carrier to change it himself. Furthermore, the selection of tones and the like must be selected from contents prepared in advance, and there is a drawback that the user cannot select the notification sound or audio content that suits his/her own preference.

The present invention has been made in view of the above-mentioned drawbacks, and it uses a pre-recorded arbitrary sound as a notification sound at the time of a ringing operation, and also allows the user to change the notification sound as many times as desired by changing the content or tone required by the user. It is an object of the present invention to provide a radio selective calling receiver that can freely change settings and can also be made smaller and lighter by eliminating the need for a message display section.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a radio section that amplifies and demodulates a radio signal received from an antenna, and a waveform shaping of the signal demodulated by the radio section to convert it into a digital signal. A waveform shaping circuit to convert, a decoder that compares the selective calling signal written in memory with the digital signal from the waveform shaping circuit, and performs any calling operation, and a decoder that converts any sound input from the microphone into a digital signal. The system is equipped with a digital recording and reproducing circuit that converts the digital information and stores it in the memory, reads out arbitrary digital information in the memory in response to a call signal from the decoder, and converts it into an arbitrary sound. The decoder has a counter and is configured to record any sound into a memory area corresponding to the value of the counter.

[Operation] The sound corresponding to the message information inputted from the microphone is converted into a digital signal by the digital recording/reproducing circuit and stored in the memory. When receiving the own selective calling number and message information, the digital information in the memory corresponding to the message information is read out, and the read digital signal is reproduced to the original arbitrary sound and used as the notification sound. You can recognize the call and at the same time know the message content by the sound.
