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.
[0004] Nowadays, mobile terminals are widely used, but there is still no system and method for controlling spe

Embodiment Construction

[0045] The power supply line is one of the most widely distributed networks, and the Power Line Communication (PLC) technology is relatively mature. The present invention uses PLC technology to realize the communication connection between the audio playback device and the audio playback control device. The control information and audio data to be played are sent to the audio playback control device, which can use PLC technology to transmit control signals and audio signals through the power supply line, and only a power cord is required between the audio playback device and the audio playback control device To achieve communication, users can conveniently set up audio playback devices. However, the present invention is not limited to the use of PLC technology to realize the communication between the audio playback device and the audio playback control device, and other transmission technologies may also be used.

[0046] As shown in FIG. 1, it is a schematic structural diagram of ...

Abstract

The invention relates to the audio broadcast system, including the audio broadcast equipment, audio broadcast control device, application server and mobile terminal. The invention also relates to audio broadcast control method, the mobile terminal sends audio broadcast request information to the application server; the application server produces audio broadcast control information according to the audio broadcast request information and send it to the audio broadcast control device; the audio broadcast control device sends control signal and digital audio signal according to the broadcast control information, the audio broadcast device broadcast digital audio signal according to the control signal. The invention achieves the remote control of the audio player device; communication can be realized just need power cord between the audio broadcast device and the audio broadcast control device, the users can set up audio player device conveniently; it can control audio broadcast device broadcast downloaded from the Internet or local audio data by mobile terminal; it can set remote play list to control the broadcast list content of the audio broadcast device by mobile terminal.

Description

Technical field [0001] The invention relates to an audio playback system and an audio playback control method, in particular to an audio playback system and an audio playback method that can be controlled by a mobile terminal, and an audio playback device and an audio playback control device related to the audio playback system and the audio playback method. Background technique [0002] There are three connection methods between the existing speakers and the host device that controls the speakers: the first one needs to be connected to a power cord and a dedicated signal line (such as an audio cable); the second needs to be connected to a power cord and a dedicated configuration Wireless interface (such as WLAN, Bluetooth); the third type requires 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 the host that controls the speaker device. [0003] For existing speaker device...
