2. Description of the Related Art Generally, AI (Artificial Intelligen) is used.
ce: artificial intelligence) timer sound device, tape playback, CD
It has a sound source circuit that can select and output one of a plurality of audio output systems such as reproduction, MD reproduction, and radio broadcast reception. The sound output of the sound source circuit can be automatically started according to a preset program and stopped at a predetermined time. For example, the music of a specific track of a CD is repeatedly reproduced from 8:00 AM, and 8:30 AM , A radio broadcast of a specific broadcast station is received, and a specific song on a cassette tape is reproduced from 8:45 AM.

[0003] In addition to the above-described program reproduction, there is also a configuration in which a program recording of receiving a radio broadcast from a specific broadcasting station and recording the program on a cassette tape can be performed (for example, see Japanese Patent Application Laid-Open No. 61-196449). ).

The volume control device of such an AI timer audio device is for controlling the volume when the sound source circuit is started automatically or at an arbitrary time, and is fixed to a storage medium such as a ROM. The stored data is read out at the start of operation, and the sound output is set to an appropriate value based on the data.

The stored data has various modes according to the state of the program operation of the tone generator circuit. When the tone generator circuit is activated, a specific volume is set (simple ON operation) and when the tone generator circuit is activated, At the time of the operation, there is a case where the volume is increased with the passage of time at a low volume (fade-in operation), and a case where the volume is reduced at the specific volume as the operation is approached at the end of the operation (fade-out operation). The volume control is selected and used according to the state of the program operation of the tone generator circuit.

The data of the volume change characteristics of the volume setting or the fade-in / out are stored as fixed data of the greatest common denominator that can be satisfied by the majority of users, and users are not satisfied with the current volume. in case of,
This is achieved by operating a so-called manual volume to increase or decrease the volume.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block circuit diagram of a volume control device of an AI timer audio device according to an embodiment of the present invention. A CPU 1 for controlling the entire device in a complex manner includes a “tape reproduction circuit 2a, a CD reproduction circuit 2b, The sound source circuit 2 including the MD reproducing circuit 2c and the radio receiving circuit 2d is connected.

A speaker 5 is connected to an output terminal of the tone generator 2 via a volume controller 3 and a power amplifier 4 which are formed, for example, of a voltage-controlled amplifier.

The CPU 1 is connected to a ROM 14 in which basic program data for controlling the entire AI timer audio equipment in a complex manner is stored. A RAM 6 in which data for the complex control can be freely written and read is connected. The initial value storage unit 7 and the backup storage unit 8 are connected.

The initial value storage unit 7 is constituted by a ROM for fixedly storing fixed data of the sound output volume value when the sound source circuit 2 is automatically started to operate. That is, the initial volume data 7a, the ON change characteristic data 7b, and the OFF change characteristic data 7c are stored.

The initial volume data 7a is initial value data of sound output when the sound source circuit 2 is automatically started.
The on-change characteristic data 7b is data corresponding to an on-change characteristic (fade-in characteristic) in which the sound output at the time of automatically starting the sound source circuit 2 increases from a low volume to a high volume, and the off-change characteristic data 7c is The data corresponds to an off-change characteristic (fade-out characteristic) in which the sound output when the sound source circuit 2 is automatically stopped is reduced from a large volume to a small volume.

The backup storage section 8 is used to store arbitrary data of the volume value of the sound output at the time of automatically starting the sound source circuit 2 and store it in a nonvolatile manner.
It is composed of an EP ROM, and is composed of three types of data: volume data 8a, ON change characteristic data 8b, and OFF change characteristic data 8c, and can be arbitrarily set by the user as described later.

Operation setting input circuit 9 connected to CPU 1
Is for the user to arbitrarily set (program) the transmission system of the audio signal output from the sound source circuit 2 and the output start time, etc., and to input the reproduction state and the reproduction timing by a plurality of setting switches (not shown). be able to.

Each of the up key 11, the down key 12, and the enter key 13 connected to the CPU 1 operates the sound source circuit 2 and the sound output from the speaker 5 in accordance with the operation timing. The key is used for setting as 8a, ON change characteristic data 8b, and OFF change characteristic data 8c.

In the AI timer audio equipment configured as described above, when the power is turned on, it is determined in step S1 of the flowchart shown in FIG. 2 whether or not there is valid data in the backup storage unit 8. (N
In the case of o), the process proceeds to the next step S2, where the “initial volume data 7a, the ON change characteristic data 7
b, OFF change characteristic data 7c ”is copied to the RAM 6. On the other hand, when there is valid data (in the case of Yes), the “volume data 8a, on-change characteristic data 8
b, OFF change characteristic data 8c ”is copied to the RAM 6. The volume control by the data copied to the RAM 6 in this way is performed with an operation program executed later.

When the volume is to be set, the counter X (1 to 24) of the CPU 1 is set to 0 in step S4 of the flowchart shown in FIG. 3, and the process proceeds to the next step S5, where the X-th data is set. The setting starts.

First, in step S6, the set key 1
Is 0 pressed? Is determined, if the set key 10 is not pressed after the data is set by operating the up key 11 and the down key 12 (in the case of No), the steps S5 and S6 are executed again, When there is an operation (Y
In the case of es), the process proceeds to step S7, and the counter X is incremented.

In the next step S8, the determination of the counter X ≦ 24 is performed.
Pressing enter key 13? Is determined, and in the case of Yes, the backup storage unit 8 is determined in the next step S10.
The setting data set by the set key 10 and the up key 11 is copied (rewritten) to any one of “volume data 8a, on-change characteristic data 8b, and off-change characteristic data 8c”. If No in step S9, step S9 is executed again.

Therefore, the operation setting input circuit 9 allows the tape reproducing circuit 2a, the CD reproducing circuit 2b, and the M
When the operation and the operation timing of the D reproduction circuit 2c and the radio reception circuit 2d are set, the operation program is stored in the RAM 6, and at the same time, the volume setting in each step of the operation program is set by the set key 10 and the up key 1.
1, the down key 12 and the enter key 13.

For example, at 8:00 AM, the CD reproducing circuit 2b
Is set in the operation setting input circuit 9 and the operation program is stored in the RAM 6, and at the same time, all the songs in the CD are stored.
The backup storage unit 8 stores the data at the start of the operation as fade-in characteristics having a gradual volume increase characteristic as ON change characteristic data 8b. In the same manner, the type and operation time of the reproduction system in the tone generator circuit 2 are stored in the RAM 6 as data, and the "volume data 8a, on-change characteristic data 8b, and off-change characteristic data 8c" in the backup storage unit 8 are used as necessary. Data is stored.

When the sound output start time set in advance by the operation setting input circuit 9 is reached, each part of the circuit is set to the operation start state by a command from the CPU 1 and the volume control is started. Then, step S1 of the flowchart shown in FIG.
First, as shown in FIG.
It is determined whether or not c has elapsed, and if No, step S11 is executed again.

If YES after 100 msec from the start of the volume control, the process proceeds to the next step S12.
This step S11 is an uncertain transition from when the volume control start command is issued from the CPU 1 to when the "sound source circuit 2, volume control unit 3, and power amplifier 4" can operate stably. This is to prevent a proper operation.

Then, in step S12, the CPU 1
Is determined not to be Y = 0, and Yes
In the case of, the counter Y is decremented in the next step S13, and it is determined whether or not the counter Y is 0 in the next step S14, and in the case of Yes, the next step S1
Then, the process proceeds to step S5, where the count data is set in the counter Y, and any one of the "volume data 8a, the on-change characteristic data 8b, and the off-change characteristic data 8c" in the backup storage unit 8 is transferred to the RAM 6. Be prepared for the control to be performed.

Accordingly, the sound output value and the fade-in / out sound volume change characteristics associated with the program reproduction set by the operation setting input circuit 9 are not all fixedly stored in data, and are adjusted to the user's preference. Since it can be set using the up key 11, the down key 12, and the like, there is no need to manually increase or decrease the volume after the start of reproduction as in the related art.

When the user does not store data in the backup storage section 8, the standard "initial volume data 7a, on-change characteristic data 7b, off-change characteristic data" stored in the initial value storage section 7 are stored. 7c "is used as a substitute, so that the volume does not greatly differ.

It is to be noted that the present invention is not limited to the above-described embodiment, but may adopt various modifications. For example, the configuration of the tone generator 2 may be a tape reproducing circuit 2a and a radio receiving circuit 2d. Or a DVD audio playback circuit, etc., is completely arbitrary. In short, one of a plurality of audio output systems such as radio reception, tape playback, and CD playback is selected and output. Any configuration may be used as long as it is configured as described above.

The form of the volume control may be cut-in at a predetermined time at a predetermined volume or cut-out at a predetermined time at a volume 0, fade-in / out, or fade-in / out. Of course, the time may be shortened or lengthened, or may be changed stepwise.

[0039]

As is apparent from the above description, the volume control device of the AI timer audio equipment according to the present invention has an initial value storage unit, a backup storage unit, and a volume control unit. The sound output value and the fade-in / out volume change characteristics are not fixedly stored in the data, and can be set using operation keys or the like according to the user's preference. There is no need to manually increase or decrease the volume after the operation.

When the user does not store data in the backup storage unit, the standard data stored in the initial value storage unit is used instead, so that the volume does not greatly differ. .

Therefore, when the sound source circuit is automatically activated based on the setting program to obtain an acoustic output, the volume can be freely set according to the user's preference, and furthermore, the sound source circuit can be set based on the setting program. It is possible to provide a volume control device for an AI timer audio device that can set the volume freely according to the user's preference even when the operation is automatically stopped.
