Wireless digital remote control sound box device

Abstract

The invention relates to a wireless digital remote control sound box device which comprises a sound box; the sound box is internally provided with a main control module and a wireless receiving module; the sound box also comprises a universal serial bus (USB) transmitter; the USB transmitter is provided with a USB interface used for being connected with a computer; the USB transmitter is provided with a wireless transmitting module and a control module; the control module is used for sending a control command to the sound box by the wireless transmitting module; the control command is received by the wireless receiving module of the sound box and then is transmitted into the main control module; and therefore, the sound box can be controlled. The wireless digital remote control sound box device can be connected with computer equipment in a communication way, so that the music can be played from a long distance, the transmission effect is good, and the remote control for the sound box can be conveniently carried out.

Description

technical field [0001] The invention relates to a sound box, in particular to a wireless sound box product, which can realize wireless communication with a computer and has strong anti-interference ability. Background technique [0002] At present, various TVs, CDs, MP3s, I-pods, PCs, and Radios with audio output functions in the prior art are all connected to the sound box through wired methods. This connection method has the problem that the connection is very troublesome. [0003] Some wireless speakers have also appeared in the prior art. For example, patent application 200520113088.4 discloses a transmitting module for a wireless speaker and a wireless speaker including it. The wireless speaker proposes a transmitting module for a wireless speaker, including : A USB sound card including a USB interface, used to decode the audio signal received from the audio source through the USB interface, and convert it into an analog signal through digital-to-analog conversion for ...

Problems solved by technology

[0005] However, these speakers do not have communication connections with computer equipment, nor can infrared remote control music players realize long-distance music player operations. A simple forwarding of the audio signal does not implement the input and output control of the audio signal

Moreover, the wireless transmission frequency of these speakers is basically the same as the frequency of daily mobile phones, which will cause interference from other external transmission signals, making the transmission effect of wireless speakers poor, the anti-interference effect is not ideal, and it is difficult to meet the requirements of use
