Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sound control circuit for an automobile sound generating device that generates sound information in conjunction with the operation of a plurality of switches, and in which the sound information can be selected.

A conventional voice generator for automobiles is shown in FIGS. 1 and 2, and its operation switch 1 is composed of two electric circuits, and when the knob 1a is lightly flushed, the voice explanation circuit switch section 1b is activated. When the switch is turned on, the sound generating device 2 generates the contents of the switch, such as a wiper switch, a headlamp switch, or a defroster switch.

After the driver confirms the contents of the switch by voice, if he presses the knob 1a again, the main circuit switch section 1c (/'iON) is activated, and the main circuit 3 is activated.

In the figure, 3' is another main circuit, 1'b is another voice explanation circuit switch section, and 1'c is another main circuit switch section.

The operation switch 1 is configured as a two-stage switch, and even when the driver does not need to confirm the contents of the switch, the audio explanation circuit switch section 1b is turned on to generate a sound indicating the contents of the switch.

Furthermore, if a plurality of switches malfunction simultaneously or within a short period of time, it may not be possible to immediately cancel any of the voice explanations, resulting in unnecessary voice information being generated.

Further, when the explanation circuit of a switch is turned on and the explanation circuit of another switch is turned on within a certain period of time, an audio explanation of both switches may be provided.

The present invention was devised to solve the above-mentioned problems, and includes a timer circuit between the voice explanation circuit switch section and the voice generator, and the voice explanation circuit switch section is ONt,
If the main circuit switch section is turned on within a certain period of time after that, the audio explanation will not be performed, and if another audio explanation circuit switch section is turned on within a certain period of time after one audio explanation circuit switch section is turned on, The object of the present invention is to provide an audio control circuit for a new automobile audio generating device in which audio explanation is not performed by the first audio explanation circuit switch section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The audio control circuit in the automotive audio generator according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 3 shows a specific example of the audio control circuit according to the present invention, and is an example of the audio control circuit configured with a single operation switch 1. As shown in FIG.

4 is a first monostable multivibrator, 5 is a second monostable multivibrator, 16 is a UNAND gate, and 7 is a knot gate.

Therefore, two monostable multivibrators 4.5, NA
The ND gate 6 and the NOT gate 7 constitute a timer circuit.

Alternatively, the sound generating device 2 can be configured with an edge detection circuit.

When the driver lightly presses the operation switch 1, the audio explanation circuit switch section 1b is turned on.

Therefore, the first monostable multivibrator 4 is activated, and when it is terminated, the second monostable multivibrator 5 is activated and outputs an H level output.

After the voice explanation circuit switch section 1b is turned on, the main circuit switch section 1c is off (1), that is, when the driver lightly presses the operation switch 1, the not gate 7 (ri'H level output is maintained). do.

When the NAND gate 6 receives the H level signal from the second monostable multivibrator 5, it inverts to the L level output, triggers the sound generating device 2, and generates the sound corresponding to the switch contents.

When the driver further presses the operation switch 1 while the first monostable multivibrator 4 is in operation, the main circuit switch section 1c is turned on and the output is inverted to the 7idL level.

Therefore, even if the NAND gate 6 receives an H level signal from the second monostable vibrator 5, the output does not invert from the H level, and the sound generating device 2 is not activated.

FIG. 4 (r) is an example of a voice control circuit composed of 12 operation switches.

Reference numeral 8 denotes a first operation switch having the same configuration as the operation switch 1 described above, and includes an audio explanation circuit switch section 8a and a main circuit switch section 8b.

Reference numeral 9 denotes a second operation switch having the same configuration as the operation switch 1, and includes an audio explanation circuit switch section 9a and a main circuit switch section 9b.

10 is a first timer circuit, and 10' is a second timer circuit.

The first timer circuit 10 does not operate the audio generator 2 when the main circuit switch 8b is turned on within a certain period of time after the audio explanation circuit switch 8a pressed on the first operation switch 8 is turned on. , after the voice explanation circuit switch section 8a is turned on, the second operation switch 9 is turned on within a certain period of time.
When the audio explanation circuit switch section 9a is turned on, it has a function of not driving the audio generating device 2 by receiving a signal from the second timer circuit 10'.

The second timer circuit 10' is the first timer circuit 10'.
It has the same function as .

The first and second timer circuits 10, 10' may be composed of monostable multivibrators.

For example, the two timer circuits 10 and 10' are connected to two monostable multi-by-break circuits 4 and 4 shown in FIG.
5. It can be configured with a NAND gate 6 and a NOT gate 7.

If the driver lightly presses the first operation switch 8,
The audio explanation circuit switch section 8a is turned on.

When the main circuit switch 8b is OFF after the voice explanation circuit switch section 8a is turned on, the first timer circuit 10 triggers the voice generation device 2 after a certain period of time has elapsed, and the voice explanation circuit switch is turned on. A sound indicating the switch contents regarding the section 8a is generated.

When the driver turns on the voice explanation circuit switch section 8a toward the first operation switch 8 and then turns on the main circuit switch section 8b within the above-mentioned fixed time, the first timer circuit 10
does not operate the sound generator 2.

At this time, the main circuit 3 starts operating. After the driver lightly presses the first operating switch 8 to turn on the audio explanation circuit switch section 8a, the driver lightly presses the second operating switch 9 within the above-mentioned fixed time to turn on the audio explanation circuit switch section 9.
When a is turned on, the first timer circuit 10//i, the second
By receiving a signal from the timer circuit 10' indicating that the audio explanation circuit switch 9a is ON, no trigger signal is output to the audio generator 2.

In this case, since the trigger signal is output from the second timer circuit 101, the audio generating device 2 generates the audio of the switch contents regarding the audio explanation circuit switch section 9a of the second operation switch 9.

The audio control circuit for the automotive audio generator according to the present invention has an inclined configuration and has the following effects.

It is equipped with a timer circuit, so if you press the operation switch lightly and the timer circuit is operating, press it again.
Since the sound generating device does not generate sound, it is advantageous if the driver does not need to check the contents of the switch.

Further, in a plurality of operation switches, if the first operation switch is lightly pressed and then the second operation switch is lightly pressed within a certain period of time, the audio explanation based on the first operation switch is not performed. This has various effects, such as making it possible to combine sounds, allowing for immediate cancellation in the event of an erroneous operation.
