Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage and calling function of a receiver, and particularly to a receiver suitable for setting a reception frequency and a volume level in a memory.

[0002]

[Prior art]

 Conventionally, many receivers in which the reception frequency and the like are controlled by a microcomputer (hereinafter simply referred to as a microcomputer) to set a memory have been provided that perform the operation of the flowchart shown in FIG.

Generally, a receiver tunes a received signal received by a receiving antenna by a receiving circuit (not shown) to a desired frequency of a broadcasting station, selectively amplifies it, converts it into an audio signal, and listens to it. It was The reception frequency tuning of this receiver circuit was controlled by the built-in microcomputer.

The operation of the above microcomputer control will be described with reference to the flowchart of FIG. The operation key (not shown) connected to the microcomputer is operated (step S10), and it is determined whether the operation of this operation key is a memory key operation for storing the reception frequency (step S11), and the memory is stored. In the case of a key operation for performing an operation, the received frequency data input from the operation key can be stored.

When the reception frequency data is already stored in the memory, it is determined that the key operation is an operation for calling the memory (step S13), and the microcomputer receives the reception frequency data from the memory. Calling (step S14), the receiving circuit is controlled to set the called reception frequency (step S15).

As described above, the storage and the call to the memory under the control of the microcomputer can easily set the reception frequency of the receiver.

[0007]

[Problems to be solved by the device]

 However, the above-described conventional microcomputer control of the receiver executes only the storage of the reception frequency and the call setting to the reception circuit, and has nothing to do with the setting of the sound output volume level. For this reason, the volume level is set higher when receiving the above-mentioned music-centered broadcast stations, compared to the stations mainly broadcasting music or broadcast content centered on announcements. When receiving a station, it was not possible to control the microcomputer by setting the volume level low, and the volume level of the volume adjustment circuit had to be set for each reception.

The present invention has been made in view of the above points, and an object thereof is to solve the drawbacks of the conventional example and to provide a receiver that simultaneously controls a reception frequency and a volume level by a microcomputer. It is in.

【Example】

 An embodiment of a receiver according to the present invention will be described with reference to FIGS. FIG. 1 is a functional block diagram showing the configuration, FIG. 2 is a block diagram of hardware, and FIG. 3 is a flowchart explaining the operation.

In the figure, 10 is a receiver, which has an operation key input terminal 11 for operating a built-in microcomputer and an antenna input terminal 12, and an antenna connected to the antenna input terminal 12 (see FIG. The reception signal received by (not shown) is supplied to the reception circuit 13 inside the receiver 10.

Reference numeral 14 is a volume adjusting circuit for adjusting the volume level of the audio signal received and demodulated by the receiving circuit 13 described above. The volume adjusting circuit 14 is composed of a plurality of electronic volume circuits and The audio signal which is controlled and controlled by the electronic volume is output from the output terminal 16 and is output as audio from a speaker or the like connected to the output terminal 16. Further, the microcomputer 15 can control the reception frequency of the reception circuit constituted by the PLL oscillation circuit, and can tune to an arbitrary reception frequency by the operation data from the operation key to receive.

As is well known, the microcomputer 15 is basically composed of a CPU, a ROM, a RAM, an input port and an output port (not shown), and a program for controlling the CPU is written in the ROM. According to this program, the CPU takes in the external data required from the input port or performs arithmetic processing while exchanging data with the RAM, and outputs the processed data from the output port as necessary. To do.

The receiver 10 configured as described above stores the reception frequency and volume level setting values of the receivable broadcasting stations under the control of the microcomputer 15 in the internal memory, and receives any desired broadcasting station. The stored data thus stored can be called to control and receive the receiving circuit 13 and the volume adjusting circuit 14. The operation of this receiving operation will be described with reference to the flow chart of FIG.

Generally, the broadcasting content of a broadcasting station can be broadly classified into music-oriented broadcasting and announcement-centered broadcasting, and the volume level of the volume adjusting circuit 14 can be set and listened to depending on this broadcasting content. , The reception frequency of the broadcasting station and the set value of the volume level can be associated and stored in the memory RAM.

First of all, by inputting the reception frequency of the receivable broadcasting station and the set value of the volume level matched to the broadcasting station of this receiving frequency from the operation key (not shown) connected to the input terminal 11, The microcomputer 15 determines the operation key input (step S1), and determines whether the input data from the operation key is the memory key operation data to be stored (step S2).

When the operation key input is memory key input, the microcomputer 15 stores the reception frequency according to the input data (step S3), and further stores the volume level according to the input data for setting the volume level. Can be done (step S4).

On the other hand, when it is determined that the operation key input is not the memory key input but the memory recall key operation (step S5), the microcomputer 15 recalls the reception frequency stored in the built-in memory RAM (step S6). ), The called reception frequency data can be supplied to the receiving circuit 13, and the receiving circuit 13 can be controlled to set the tuning frequency of the receiving circuit 13 by the calling reception frequency data (step S7). That is, the receiver 10 can receive the broadcasting station having the reception frequency set above.

On the other hand, almost at the same time, the microcomputer 15 recalls the volume level data stored in the memory RAM (step S8) and supplies the retrieved volume level data to the volume adjusting circuit 14 in the same manner as described above. It is possible to control the electronic volume of and to set the level of the electronic volume by the ringing volume level data (step S9). That is, the set level of the audio signal output of the receiver 10 can be determined and output to the output terminal 16.

In this way, the data stored by the storage operation of the above-mentioned flowcharts S2 to S4 is called, the reception frequency of the desired broadcasting station is demodulated by the reception circuit 13, and the optimum volume level by the electronic volume of the volume adjustment circuit 14 is set. At the same time, the output of the audio signal is automatically executed.

Although the microcomputer 15 controls the volume level with respect to the reception frequency of the receiver 10 as described above, factors that can be set in advance with respect to the reception frequency, such as bass characteristics and treble characteristics that determine sound quality characteristics, Alternatively, the stereo L / Rch balance characteristics when the user's listening position is determined can be stored and recalled by controlling with the microcomputer 15, and can be automatically set at the same time as the reception frequency as described above.
