Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a transceiver with a built-in melody generator in the transceiver body, which is easy to install and operate, and which has an inexpensive melody broadcasting function. [Structure] The frequency division ratio and duration of the programmable counter are controlled by the microprocessor from the clock signal of the control processor composed of the microprocessor used to control the setting of the frequency, etc. It is characterized in that broadcasting is performed via a low frequency power amplifier used for modulation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transceiver used for fishing boats and the like.

[0002]

[Prior art]

 Conventional transceivers, especially amplitude modulation transceivers, have a built-in low-frequency power amplifier for modulating the carrier wave.When communication is stopped, this power amplifier is used as a voice amplifier for loudspeakers. It was broadcasting music from tape recorders.

[0003]

[Problems to be solved by the device]

 As mentioned above, in the past, only the loudspeaker function of the transceiver was used, so a playback device such as a tape recorder was required to broadcast music. Therefore, there is a problem that the equipment and operation are complicated and the device is expensive.

The present invention has been made to solve such a problem, and an object thereof is to provide a transceiver with a melody playing function that is easy to install and operate and is inexpensive.

[0005]

[Means for Solving the Problems]

 In order to control communication elements such as frequency, the transceiver according to the present invention drives a processor equipped with a pre-installed microprocessor with a dedicated program to generate a melody from a clock signal and outputs it. The built-in loud sound function enables broadcasting.

[0006]

[Action]

 According to the present invention, music broadcasting can be performed by the transceiver main body without requiring a separate device.

Embodiments Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the structure of a transceiver according to the present invention, in which reference numeral 1 is an antenna for both transmission and reception, and a transceiver main body. FIG. 2 is a diagram showing a configuration for broadcasting music by a conventional transceiver, in which 1 is a transmitting / receiving antenna, 2 is a transceiver body, 3 is a tape recorder, and reproduced music signals are transmitted to the transceiver body. Supply. In FIG. 1, reference numeral 21 denotes a receiver, which receives and demodulates a designated radio wave by being controlled by a local oscillator signal of a local oscillator 22 composed of a frequency synthesizer. A low frequency power amplifier 23 operates as a modulator during communication and as a loudspeaker when transmission is stopped. Reference numeral 24 denotes a transmitter, which normally emits a radio wave modulated by voice through the antenna 1. Reference numeral 25 denotes a control processing unit, which normally controls the frequency synthesizer of the local transmission unit 22 so that the frequency corresponds to the numerical value input by the keyboard 26. When a designated key on the keyboard 26 is pressed, the melody playing mode is set, and when a desired chord number is input, the control processing unit 25 causes the programmable counter 27 to operate in accordance with the program corresponding to the input number. Generate a melody by setting the ratio and duration. The generated melody is amplified by the low frequency power amplifier 23 and broadcast from the speaker 28.

[0008]

[Effect of device]

 As described above, according to the transceiver of the present invention, since the melody can be generated inside the transceiver, a separate melody reproducing device is not required externally, the equipment and operation are simplified, and the price is reduced. be able to.
