More than 10 watts, while the overall power consumption of the set-top box and the TV is more than 100 watts. Not only increased the loss of electric energy, but also shortened the life of the TV set.

In addition, TV sets are generally bulky, fixedly installed and cannot be moved or are inconvenient to move. It is difficult for users to choose a listening location flexibly, and they can only listen to programs in the space where the TV set is installed, which is inconvenient to use.

Contents of the invention

The purpose of the utility model is to provide a home audio playback system to solve the current problems of high energy consumption and inconvenient movement when listening to audio programs on a television set.

In order to solve the above problems, the technical solution provided by the utility model is as follows:

A family audio playback system, which includes: a set-top box, used to obtain the content provided by the signal source; a first wireless communication module, connected to the audio output jack of the set-top box, for converting the audio signal output by the set-top box into radio signal; a second wireless communication module, connected to the first wireless communication module, for receiving the radio signal output by the first wireless communication module; digital power amplifier, the second wireless communication module connected to the digital power amplifier The signal input jack, the digital power amplifier amplifies and outputs the radio signal received by the second wireless communication module; the speaker is connected with the digital power amplifier through a signal line, and is used to convert and play the radio signal output by the digital power amplifier for the user to listen to the audio program.

In a preferred implementation of the above-mentioned home audio playback system, the set-top box includes a digital TV set-top box and a network set-top box.

In a preferred implementation manner of the above-mentioned home audio playback system, both the first wireless communication module and the second wireless communication module are short-range wireless communication modules.

In a preferred implementation of the above-mentioned home audio playback system, the first wireless communication module and the second wireless communication module are both bluetooth communication modules or zigbee communication modules.

In a preferred implementation of the above-mentioned home audio playback system, the speaker is a coaxial full-range speaker.

In a preferred embodiment of the above-mentioned home audio playback system, it also includes: a vacuum suction cup, used to absorb on the smooth surface of the support; a bracket, suspended on the vacuum suction cup, and the digital power amplifier and the speaker are fixed on the on the stand.

The analysis shows that when using the utility model to listen to the audio program from the set-top box, it is not necessary to turn on the TV set, the power consumption is obviously reduced, and the digital power amplifier and the loudspeaker can be moved as required.

Description of drawings

Fig. 1 is a functional block diagram of the utility model embodiment.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , the embodiment of the utility model mainly includes a set-top box 1 , a wireless communication module 21 , a wireless communication module 22 , a digital power amplifier 3 , and a speaker 5 .

Specifically, the set-top box 1 is used to acquire content provided by a signal source, which may be a digital TV set-top box or a network set-top box, and the signal source may be a cable, a satellite antenna, a broadband network, or a terrestrial broadcast. The wireless communication module 21 is connected with the audio output jack of the set-top box 1, and is used for converting the audio signal output by the set-top box 1 into a radio signal. Preferably, the input terminal of the wireless communication module 21 is a hard member 211, such as a metal plug. The wireless communication module 22 is connected with the wireless communication module 21 for receiving the radio signal output by the wireless communication module 21 . The output terminal of the wireless communication module 22 is inserted into the signal input jack of the digital power amplifier 3 , so that the digital power amplifier 3 amplifies and outputs the radio signal received by the wireless communication module 22 . Preferably, the output terminal of the wireless communication module 22 is also a hard member 221, such as a metal plug. The loudspeaker 5 is connected with the digital power amplifier 3 through the signal line 4, which is convenient for transmitting high-power signals. The loudspeaker 5 is used to convert and play the radio signal output by the digital power amplifier 3 for the user to listen to the audio program without resorting to the TV. Preferably, the speaker 5 is a coaxial full-range speaker.

More preferably, both the wireless communication module 21 and the wireless communication module 22 are short-range wireless communication modules, such as Bluetooth communication modules or zigbee communication modules. In a family, the transmission distance of the bluetooth communication module or the zigbee communication module is sufficient, so that the digital power amplifier 3 and the speaker 5 can be moved freely, and further, in order to facilitate the movement of the two, the two can be integrated into an integrated structure and installed Put it on a bracket with a vacuum suction cup, so that the digital power amplifier 3 and the speaker 5 can be arbitrarily adsorbed on the clean wall at home.

To sum up, with the help of the utility model, when using the set-top box to listen to music and broadcast, it is not necessary to turn on the TV set, so as to avoid the waste of electric energy of the TV set. Utilizing the wireless communication module to transmit audio signals can make speakers and other equipment move freely according to needs, which has great convenience.

It can be known from technical knowledge that the utility model can be realized through other implementations without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the utility model or within the range equivalent to the utility model are included in the utility model.
