Title:
REMOTE CONTROL DEVICE AND OSCILLATOR FOR SMALL ELECTRONIC EQUIPMENT
Document Type and Number:
Japanese Patent JP2711645
Kind Code:
B2
Abstract:
PURPOSE: To easily search the location of a lost remote control operation part by providing the reception circuit of a search signal on the remote control operation part, etc., and producing an oscillation sound by the search signal transmitted from the side of an electronic equipment.
CONSTITUTION: A remote control operation part 1 has the reception circuit of the search signal transmitted from an electronic equipment main body, a television set, for instance. This search signal reception circuit detects the radio waves received by an antenna 7 in a detection circuit 8 and is provided so that a reception signal may be inputted in the gate of a p-type MOSFET 10 via an amplifier 9. The source side of this p-type MOSFET 10 is connected with an oscillation circuit 11 and the output of the oscillation circuit 11 is connected with a vibration member 12 such as a piezoelectric element and a speaker, etc. Further, the output of an oscillation circuit 18 is inputted in the mixer within the television set, the search signal of the prescribed signal waveform is outputted from the mixer, the search signal is transmitted from the antenna via a high frequency amplifier 19 and a transmission sound is produced from the vibration member 12 of the remote control operation part 1.
