Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to a voice generating device for a taximeter. [Problems to be Solved by the Prior Art and Ideas] In general, a taximeter is equipped with a display that displays the fare as a means for communicating the fare to passengers. However, with this visual fare communication method,
It is difficult for the elderly and visually impaired to ascertain fair prices. As a result, a problem has arisen in which unscrupulous drivers charge illegal tolls to visually impaired people, and the morals of drivers are being questioned. In order to avoid the above-mentioned problem, a device has been proposed, for example, in Japanese Patent Laid-Open No. 57-788, which outputs the amount of the taxi fare to be paid by the customer in voice. In the proposed device, when a taxi vehicle arrives at its destination and pays a taxi fare, a voice synthesis circuit generates a voice signal for uttering the taxi fare amount and a greeting, and the voice signal is output to a speaker. By driving the system, the toll amount is output audibly, so that even the elderly and those with hearing disabilities can easily confirm the true and legitimate toll. However, the above-mentioned conventional device is equipped with a dedicated speaker that is used only to output information such as the amount of the fare, etc., resulting in problems such as increased size and cost. Therefore, in view of the above-mentioned problems, the present invention has been developed to provide a voice generator for taximeters that eliminates the need for a dedicated speaker to output information such as the fare amount in voice, thereby reducing the size and cost of the device. is intended to provide. [Means for Solving the Problems] In order to achieve the above object, the taximeter sound generating device according to the present invention is as shown in the basic configuration diagram of FIG.

The present invention is characterized by comprising a switching control means 11c for connecting the output of the car radio 3 to the speaker 4 by canceling the operation of the switching means 17 in response to the detection of the end of the audio signal by the audio signal 1b. [Operation] With the above configuration, when the payment tariff signal generated in response to the payment tariff operation performed by the driver when the passenger pays the taxi fare is input from the taximeter 2 to the payment tariff detection means 11a, the payment is detected. The switching control means 11c operates the switching means 17 based on the output of the tariff detection means 11a, and switches the speaker 4 from the output of the car radio 3 to the output of the audio signal forming means 18. The audio signal forming means 18 forms a series of audio signals for the taximeter 2 to generate audio including the fare based on the fare data generated following the payment tariff signal in response to the payment tariff operation. The signal is sent to the speaker 4 via the switching means 17, and the speaker 4 generates a sound based on a series of audio signals. Sound is generated by a series of sound signals, and the end detection means 11b
When detects the end of the series of audio signals formed by the audio signal forming means 18, the switching control means 11c controls the switching means 17 in accordance with the output of the end detection means 11b. The output of the car radio 3 is connected to the speaker 4, and the speaker 4 generates sound based on the audio signal from the car radio 3. As described above, the switching means 17, under the control of the switching control means 11c, connects the output of the audio signal forming means 18 to the speaker 4 when paying a taxi fare, and connects the output of the audio signal forming means 18 to the speaker 4 at other times. Since the output is connected to speaker 4, it is always connected to car radio 3.
The speaker 4 used to hear the voice of the driver can also be used to generate the voice of taxi fares, etc., thereby making it possible to downsize the device and reduce costs. [Embodiment] Hereinafter, an embodiment of the audio generating device for a taximeter according to the present invention will be described based on the drawings. FIG. 2 is a block diagram showing the state of use of the taximeter audio generator 1 according to the present invention. 3, a female voice, for example, is generated through a speaker 4 installed in the vehicle in advance. The car radio 3 sends a radio broadcast audio signal to the speaker 4 through the taximeter audio generator 1, so that the radio broadcast can be heard from the speaker 4 as before, but it also generates audio related to fares. In this case, the radio sound is interrupted and the sound related to the fee is preferentially emitted from the speaker 4. After the generation of the voice related to the fee ends, the system automatically returns to the radio voice again. FIG. 3 is a block diagram showing a specific configuration example of the taximeter audio generator 1. In the figure, 11 is a one-time write type one-chip microcomputer (CPU) that operates according to a predetermined program. The CPU 11 is connected to the taxi meter 2 via the interface circuit 12.
