Abstract

PURPOSE:To make the operation of an equipment easy and to prevent malfunction form being generated by providing a control circuit to control the generation of ON/OFF timing at a light emission part or a display part and to control the equipment at timing for reception by an acoustic wave detection part. CONSTITUTION:When the acoustic waves of slapping are twice detected at fixed timing, an area (b) is formed and ON/OFF rythm is generated by a light emission part 2. Then, an acoustic wave detection part 3 reads the acoustic wave inputted during while turning OFF each ON/OFF rythm and the acoustic wave inputted while turning OFF each ON/OFF rythm. When the slapping acoustic wave is generated matched with each ON/OFF rythm while turning ON each ON/OFF rythm, an area (c) is formed and the power source of the equipment is turned ON. When the above mentioned ON/OFF rythm is made frequent, the generation of the malfunction to surrounding noise is reduced. Therefore, while observing each ON/OFF rythm, it is enough only to generate the acoustic wave of slapping while turning ON light or the display. Then, correspondence can be made even to the long ON/OFF rythm.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control device that does not require a remote control transmitter at hand.

Conventional technology A conventional remote control device consists of a remote control transmitter at hand and a remote control receiver installed in equipment such as a television or video camera.
Data was sent to a remote control receiver using infrared rays and ultrasonic waves, and the remote control receiver received the data to perform various operations on the device.

Other methods that operate by recognizing speech are being developed, but they have not yet been put into practical use.

Problems to be Solved by the Invention However, in the above configuration, the remote control transmitter,
When using a remote control receiver, the remote control transmitter must always be placed near oneself, and when used by a large number of people, the remote control transmitter must be transferred by hand. Additionally, small remote control transmitters were often missing.

Next, in the case of voice recognition, it is extremely difficult to recognize surrounding noise and words, and it is unreliable unless a dedicated microphone is used. Furthermore, in terms of cost, it requires the use of a large number of dedicated ICs, making it very expensive, and it is extremely unlikely that it will be incorporated into general sets.

The present invention solves this problem, and aims to provide an excellent remote control device that allows equipment to be operated without a remote control transmitter at hand and that does not malfunction.

Means for Solving the Problems In order to solve the above problems, the remote control device of the present invention includes:
A light emitting part that emits light or a display part that displays a display, a sound wave detection part that detects sound, and a device that controls the generation of light or display in the light emission part or display part, and controls the timing of reception in the sound wave detection part. It is equipped with a control circuit that controls the

Further, the control circuit controls the device by causing the light emitting section or the display section to generate a blinking rhythm of light or display, and by making the sound wave detection timing by the sound wave detection section effective only while the blinking rhythm is turned on.

Effect With the above configuration, when a flashing rhythm of light or display is generated from the light emitting part or display part, when a sound wave such as a voice or handclap is generated in accordance with this rhythm, the sound wave detection part detects this. , it is possible to distinguish between ambient noise and operator instructions, even when the remote control transmitter is not at hand.
Able to operate excellent equipment without malfunction.

Example An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows a block diagram of a remote control device according to an embodiment of the present invention, which is implemented in a television. In FIG. 1, 1, a display section 1 such as a television screen that generates a blinking rhythm based on a rhythm signal, and a light emitting section 2 such as an LED;
A sound wave detection unit 3 such as a microphone that detects sound; a control circuit 4 that controls the generation of a blinking rhythm in the display unit 1 and the light emitting unit 2 and controls the television receiver 5 based on the timing of reception in the sound wave detection unit 3; It is equipped with

FIG. 2 is a timing chart when the television shown in FIG. 1 is turned on. Region a is in the state of reading sound waves, and this state continues until the hand-produced sound waves are detected twice at a predetermined fixed timing. At this time, devices can be distinguished by changing the timing and rhythm. Alternatively, the rhythm of this area a may be memorized so that each operator can set an arbitrary rhythm.

Next, the hand-pulsed sound waves are generated 2 times at a certain timing.
When the times are detected, the area becomes closed, and the light emitting unit 2 generates a blinking rhythm, and the sound wave detection unit 3 reads the sound waves input while each blinking rhythm is turned on and the sound waves input while each blinking rhythm is turned off. conduct.

Here, if hand-pulsed sound waves are generated only while each blinking rhythm is turned on in accordance with each blinking rhythm, region C is reached, and the power of the device is turned on.

The more complex the above blinking rhythm is, the less likely it is to malfunction due to ambient noise.
It goes without saying that the tempo and form of the flashing rhythm must be changed.

FIG. 3 shows a timing diagram of a remote control device according to another embodiment, and is an example of mode switching in the television shown in FIG. 1. Region a is in the state of reading sound waves, and this state continues until the hand-produced sound waves are detected twice at a predetermined fixed timing. This area a
When the hand-produced sound waves are detected twice at a fixed timing, the area becomes channel mode. In this channel mode, if all hand-pulsed sound waves are not detected for each blinking rhythm of the display section 1, the process advances to the next mode. Area C is the volume mode,
For each blinking rhythm of the display section 1, if a hand-pulsed sound wave is detected at even one place when the light is turned off, the mode advances to the next mode. In this case, since the other rhythms match, you can repeat the same mode again. Area d is the power OFF mode, and one hand-pulsed sound wave is generated for each blinking rhythm on the display section 1.
Input is accepted only when there is a one-to-one correspondence, and the power of the device is turned off in the next area e.

In order to identify the mode, it is preferable to display the mode on the display unit 1, which is a television screen, as shown in FIG. Furthermore, the mode may be displayed using a dedicated LCD, LED, lamp, or the like.

In the above configuration, the blinking rhythm may be stored as a memorization method so that the operator can set it arbitrarily. The storage method is omitted here because it is commonly used in multi-function telephones, synthesizers, etc. using RAM or the like.

According to the above configuration, it is only necessary to watch each blinking rhythm and generate a manual sound wave while the light or display is on.
It can easily respond to long blinking rhythms.

Further, even if the device emits a blinking rhythm in transition from area a to area i due to other noise, the noise does not match the blinking rhythm, so it will not interfere with the operation of the device.

Further, by using a highly directional microphone in the sound wave detection section, it can be made less susceptible to the influence of surrounding noise.

Effects of the Invention As described above, according to the present invention, a light emitting unit or display unit that generates light or a display, a sound wave detection unit that detects sound, and controlling the generation of a blinking rhythm in the light emitting unit or display unit, By providing a control circuit that controls the device based on the timing of reception in the sound wave detection section, the device can be operated even without a remote control transmitter at hand, and the device can be operated in an excellent manner without malfunction. I can do it.
