Abstract
A Bluetooth music receiving and playing television comprises a television and an integrated board for AC/DC Bluetooth audio decoding and Bluetooth audio amplification, and is characterized in that: the integrated board for AC/DC Bluetooth audio decoding and Bluetooth audio amplification is connected to a power supply of a television through an electronic switch, the electronic switch is disconnected when a main circuit of the television is powered on, the electronic switch is powered on when the main circuit of the television is powered off, and the audio output of the Bluetooth board is connected to a loudspeaker of a loudspeaker box of the television. Therefore, when the television works, the Bluetooth board is out of work when power is lost, the television is not influenced, when the television is turned off and is in standby, the Bluetooth board is powered on to work, and at the moment, music can be appreciated by turning on the Bluetooth of the mobile phone.
Description
Technical Field
The invention relates to a television, in particular to a Bluetooth music receiving and playing television.
Background
The television is an indispensable household appliance for daily work, study and entertainment. However, the television does not need to be watched in many times, some people do not like watching the television, but the television is still equipped in the home, so that the resource is wasted, and the television cannot play other functions.
Disclosure of Invention
The sound effect of the television is quite good generally, but the sound box of the television cannot be used for listening to music, the answer is negative, and the sound box cannot be used generally. When the user does not watch the television, the television is in a charged standby state, only a small part of a power supply of the television works in the standby state, most other circuits are not electrified, and therefore the sound box cannot work to listen to music.
A Bluetooth audio receiving and amplifying circuit board powered by mains supply is adopted to receive music signals, music is played through a sound box of a television, if the television is in standby, a Bluetooth circuit is powered on to work, and when the television is watched, the Bluetooth circuit is powered off to work, so that the television and a Bluetooth sound box are connected together and work independently. The Bluetooth audio receiving and amplifying circuit adopts an integrated board for decoding the AC/DC Bluetooth audio and amplifying the Bluetooth audio, and the integrated board has very small volume and can be placed in almost any space in a television.
A Bluetooth music receiving and playing television comprises a television and an integrated board for AC/DC Bluetooth audio decoding and Bluetooth audio amplification, and is characterized in that: the integrated board for AC/DC Bluetooth audio decoding and Bluetooth audio amplification is connected to a power supply of a television through an electronic switch, the electronic switch is disconnected when a main circuit of the television is powered on, the electronic switch is powered on when the main circuit of the television is powered off, the audio output of the Bluetooth board is connected to a loudspeaker of a loudspeaker box of the television, and the television circuit and the Bluetooth integrated board are mutually independent and cannot work simultaneously. Therefore, when the television works, the Bluetooth board is out of work when power is lost, the television is not influenced, when the television is turned off and is in standby, the Bluetooth board is powered on to work, and at the moment, music can be appreciated by turning on the Bluetooth of the mobile phone. This is different from the bluetooth function that has in the TV main circuit board, and its bluetooth circuit can not be independent of the main circuit and independent work, and the main circuit trouble bluetooth just can not work, and TV main circuit and bluetooth circuit are completely independent in this patent, do not influence each other.
Drawings
Fig. 1 is a functional schematic diagram of a liquid crystal television circuit.
Fig. 2 is a schematic circuit function diagram of a bluetooth music receiving and playing television.
FIG. 3 is a functional schematic diagram of the circuit for AC/DC Bluetooth audio decoding Bluetooth audio amplification.
Detailed Description
As shown in fig. 1, it is a schematic diagram of the circuit function of a common liquid crystal television, and it can be seen from the schematic diagram that the audio circuit is a part of the main circuit and cannot work alone.
As shown in fig. 2, the circuit function diagram of a bluetooth music receiving tv set is shown, a bluetooth audio board is connected to an internal power supply of the tv set through an electronic switch, the electronic switch is controlled by a main circuit of the tv set, when a main circuit of the tv set works, the electronic switch is disconnected, the bluetooth board is powered off and does not work, when the tv set is turned off for standby, the main circuit of the tv set is powered off, the electronic switch is turned on, the bluetooth board is powered on to work, an audio output on the bluetooth board is connected to a loudspeaker of the tv set, at this time, bluetooth of a mobile phone is turned on, then the music of the mobile phone is played, the music of the mobile phone is sent out through the bluetooth of the mobile phone, the music is received by the bluetooth board in the tv.
As shown in fig. 3, the functional diagram of the AC/DC bluetooth audio decoding bluetooth audio amplifying circuit is shown, the AC mains supply supplies direct current to the bluetooth audio decoding circuit and the audio amplifying circuit through voltage reduction, rectification and filtering, and the AC/DC conversion circuit, the bluetooth audio decoding circuit and the audio amplifying circuit are integrated on one board, so that the size can be very small, and the installation is convenient.
