Abstract

PURPOSE:To instantaneously discover the place of a remote controller by receiving a sound signal from a sound signal generating means, emitting a sound with a sounding means and informing a user of the place of the remote controller itself. CONSTITUTION:As a sound signal generating means 1, for example, the sound is emitted by clapping the hands. After the sound is received by a sound signal retrieving means (sound pressure sensor) 4 of a remote controller retrieving device incorporated into a remote controller 2 and amplified by an amplifying means (amplifier) 5, a comparing means 6 compares that the output of the prescribed level or above is obtained, and at the time of the prescribed level or above, the buzzer is sounded by a sounding means 7, namely, a buzzer circuit 7. Thus, when the user searches the remote controller, the place of the remote controller can be easily discovered by generating the buzzer sound from the remote controller and searching the place for generating the sound with the simple action such as clapping the hands.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a remote control search device.

BACKGROUND OF THE INVENTION Currently, remote controls are used for televisions, air conditioners, video cameras, etc. due to their ease of use.

Problems to be Solved by the Invention However, there are so many remote controls that it is often difficult to know where they are placed. Therefore, when operating each home appliance, the first step is to find where the remote control is placed.

It's very troublesome to find something because it's on a desk or on a chest of drawers.

With conventional technology, there is no way to find out where the remote control is placed (it simply relies on the user's memory).

Therefore, an object of the present invention is to enable the user to immediately find the location where the remote controller is located, without having to spend time searching for where the remote controller is located.

Means for Solving the Problems In order to solve the above problems, the remote control search device of the present invention includes a sound signal search means for searching for a sound signal from a sound signal generation means that outputs a sound of a predetermined frequency; an amplification means for amplifying the signal from the search means; a comparison means for comparing whether the signal from the amplification means is at a sound signal level higher than a predetermined level; and a comparison means for comparing whether the signal from the amplification means is at a predetermined level or higher. and a sounding means for emitting a sound.

Operation When using the above means to find out where the remote control is placed, if the button of the sound signal generating means placed at a predetermined position is pressed, a sound signal is output, and the sound signal of the remote control placed at an unknown location is pressed. The search means receives, amplifies and compares the sound signals, and then the sound generation means produces a sound to inform the user of the location of the remote control itself.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

As the sound signal generating means 1 in FIG. 1, for example,
Clap your hands and make a sound. The sound is received by the sound signal search means (sound pressure sensor) 4 of the remote control search device 3 incorporated in the remote control 2 shown in FIGS. 1 and 2, and the amplification means (amplifier)
After amplification in step 5, comparison means 6 compares the output to see if it is above a predetermined level, and if the output is above the predetermined level, sounding means 7 and buzzer circuit 7 in FIG. 2 sound a buzzer.

In this way, if the user clap their hands when searching for the remote control, the remote control will generate a buzzer sound and the user will immediately know where the remote control is.

It should be noted that as long as the hand is used as a sound signal generating means (sound) and the sound is of a certain frequency, there is no particular restriction.

Further, although a sound pressure sensor is used as the sound signal search means, a receiver having frequency selectivity may also be used.

Effects of the Invention With this remote control search device, when a user searches for a remote control, he or she can easily locate the buzzer by emitting a buzzer sound from the remote control and searching for the source of the sound with simple actions such as clapping his/her hands.
