Embodiment Construction

[0037]A method for wireless audio transmission, which uses an audio conversion device to convert a received Bluetooth audio signal into an infrared audio modulation signal, and then transmits the infrared modulation signal to an infrared receiving speaker, and the infrared receiving speaker demodulates the received infrared modulation signal , the audio speaker is driven by the audio amplifier circuit to produce sound.

[0038] An audio device for wireless audio transmission, including an audio conversion device 1, which converts Bluetooth audio to infrared audio transmission, serves as a Bluetooth audio receiver, and supports the standard Bluetooth audio transmission application layer protocol. Convert Bluetooth stereo transmission to infrared audio signal transmission. The audio conversion device 1 includes a shell 10, the shell 10 is provided with a bluetooth signal receiver 101 based on a standard bluetooth link and a bluetooth audio transmission application, and the bluet...

Abstract

The invention discloses an audio wireless transmission method. According to the technical scheme, an audio conversion device is used for converting a received Bluetooth audio signal into an infrared audio modulation signal, then the infrared audio modulation signal is sent to an infrared receiving acoustic device which is used for demodulating the received infrared modulation signal to generate an audio signal, and an audio amplifying circuit is used for driving an acoustic loudspeaker to produce sounds. The audio wireless transmission method and the acoustic device aim to overcome the defect of an existing wireless audio transmission technology, an application that the Bluetooth and the infrared audio transmission technology are combined is provided, Bluetooth audio playing of a standard main end sound source device can be supported, and the audio transmission method that a plurality of acoustic receiving end devices can simultaneously receive can also be achieved. The invention further provides the application that the Bluetooth and the infrared audio transmission technology are combined and an audio wireless transmission acoustic device which can support Bluetooth audio playing of the standard main end sound source device and also can achieve simultaneous receiving of the acoustic receiving end devices.

Description

【Technical field】 [0001] The invention relates to a method for wireless audio transmission and an audio device for realizing the transmission system. [0002] The invention relates to a method for converting and transmitting an audio wireless signal, and a conversion device for realizing the conversion and transmitting. [0003] The invention relates to an audio and lighting device, more precisely an audio device capable of receiving wireless infrared audio signals and having lighting functions. 【Background technique】 [0004] With the continuous improvement of people's living standards, the requirements for sound effects are getting higher and higher, and sound devices need to be distributed in different positions to form better sound effects. The audio delivery system for such "distributed" speakers can be installed and configured via a wired connection, or it can be implemented using a variety of wireless technologies. Although the traditional wired connection method ha...
