HIGH SOUND WAVE SENSING TYPE SOUND TRANSMITTER FOR REMOTE CONTROL SWITCH

摘要

PROBLEM TO BE SOLVED: To find a remote control switch rapidly and accurately at the time of missing it by sensing high sound wave emitted by a user, and converting the high sound wave into sound to transmit it. ;SOLUTION: This high sound wave sensing type sound transmitter is composed of a sensing device 1 for sensing high frequency wave, a converter for converting high frequency wave into sound, and a tansmitter 2 emitting sound. A remote control switch for a television or a video is easily lost and heretofore looked for by visual observation, but this high sound wave sensing type sound transmitter is fitted to the remote control switch, and a user emits high frequency wave when the remote control switch is missing. The high frequency wave is sensed and converted into sound which is emitted to allow the remote control switch to be looked for following the sound. This sound transmitter can be fitted not only to the television and video but also to all objects easy to lose.;COPYRIGHT: (C)1999,JPO
