Embodiment Construction

[0014] A type of ultrasonic remote control adapter according to the present invention, its specific implementation method is to design the shape with a plug on the back, directly plug it into the mains socket, and transmit the remote control signal wirelessly in the form of simulating Bluetooth keyboard buttons through the Bluetooth interface, The internal sensor uses a piezoelectric ceramic chip as a high-frequency signal pickup to analyze and optimize the audio frequency of the tambourine and passive ultrasonic sounding skin. In this way, the display and brightness of the external host or remote control lighting equipment can be controlled through the tambourine or the sounding leather bag, indicating the user's action in the current environment, which is suitable for entertainment use.

Abstract

The invention discloses an ultrasonic-like remote control adapter device which is characterized in that an audio signal of which the audio oscillation frequency is 20Khz or nearby a specific high-frequency ultrasonic frequency and the audio amplitude reaches the specific level is identified according to the presetting, and after an effective audio signal is received, the audio signal is converted into a remote control signal, then the converted remote control signal is transmitted, and a transmission interface of the remote control signal comprises one or more of Bluetooth, WIFI, infrared, short wave, Ethernet and 485 network interfaces. The receiving device supplies power by virtue of an external power supply and / or an internal battery.

Description

technical field [0001] The invention relates to a kind of ultrasonic remote control switching device, which converts an audio signal of a specific frequency and amplitude into a remote control signal, and transmits it in the form of bluetooth or other interfaces. Background technique [0002] Ordinary ultrasonic remote control devices can only be remotely controlled locally, and do not have the functions of cascading and remote control forwarding. [0003] If the signals of external devices such as tambourines are captured and recognized, and converted into remote control signals that other remote control devices can recognize, any sounding props can be bound to the remote control signal to achieve the effect of custom remote control. Contents of the invention [0004] The invention discloses a kind of ultrasonic remote control adapter, which is characterized in that according to preset or learning, the built-in sensor can identify the audio signal whose audio oscillation ...
