Audio playing device

Abstract

The invention relates to an audio playing device, which comprises a sound box and a sound box adaptation module, wherein the sound box is connected with the sound box adaptation module; the sound box adaptation module communicates with an audio playing control device through a power line, and is used for demodulating a power line communication signal transmitted by the power line to obtain a control signal and / or an audio signal, and outputting the control signal and / or the audio signal to the sound box; and the sound box is used for playing the received audio signal according to the control signal. Remote control over the audio playing device is realized. The audio playing device can communicate with the audio playing control device only by a power cord, so a user can conveniently set the audio playing device, controls the audio playing device to download audio data from a network or the local audio data of the control device by a mobile terminal, and remotely set a play list and control the audio playing device to play the contents of the play list by the mobile terminal.

Description

[0001] This patent application is submitted to China Patent Office on August 25, 2006, the application number is 200610111846.8, and the divisional application of the Chinese patent application titled "Audio Playing System and Audio Playing Control Method". technical field [0002] The invention relates to audio technology in the communication field, in particular to an audio playback device. Background technique [0003] There are three connection methods between the existing speaker and the host device that controls the speaker: the first one needs to be connected to the power line, and at the same time connect a dedicated signal line (such as an audio cable); the second type needs to be connected to the power line, and a dedicated The wireless interface (such as WLAN, Bluetooth); the third type needs to be connected to a dedicated signal line with power supply function (such as a USB cable). The user can perform program selection and program playback control operations on...

AI Technical Summary

Problems solved by technology

For the Bluetooth interface, it can only be transmitted in a short distance and a good wireless environment. If the speaker and the host that controls the speaker are not in the same room and the distance exceeds 10 meters, the transmission rate will be greatly affected.

[0005] Nowadays, mobile terminals are widely used, but there is still no system and method for controlling speakers to play audio through mobile terminals, and it is impossible to perform remote control operations on speakers through mobile terminals; it is impossible to select and play program content on designated speaker devices through mobile terminals ; Also can't customize the network playlist (or claim network virtual CD) that can be played on the sound system by mobile terminal
