Problems solved by technology

[0003] 1. Most speakers do not support the Bluetooth playback function, even if the sound quality is better, the price is higher or the older speakers may not support the Bluetooth audio playback function;
[0004] 2. During the use of audio with Bluetooth playback function, it is usually hoped that the playback device can be connected to Bluetooth to play music, and the Bluetooth device can be disconnected after use to stop, but this requires that the audio power supply is always connected, and the audio standby Power is usually higher and consumes more power

Abstract

The invention discloses a Bluetooth 4.0 audio receiver with a power saving function, and a control method. A conventional Bluetooth sound device does not have a Bluetooth playing function, and a useralso wants to instantly play the music after a playing device with the Bluetooth function is connected with the sound device, and stops the playing after disconnecting the Bluetooth device, which requires the power of the sound device to be always in a connected state. However, the standby power of the sound device is bigger, and a lot of electricity is consumed. The receiver provided by the invention comprises a housing (1), and the interior of the housing (1) is provided with two clamping boards, wherein the interior of a groove between the two clamping boards is provided with a control board (4) in an inset manner. The left side of the control board is welded with an AC-DC isolating power supply (2) and a relay (7), and the right side of the control board is connected with a Bluetooth receiving module. The left side of the housing is provided with a sound device power interface (10) and a 3.5mm audio output interface (8). The left side of the housing is provided with a turn-off volume adjustment rotary button (9). The right side of the housing is provided with a power socket (6), and the top of the housing is provided with an LED lamp (3). The receiver provided by the inventionhas the power saving function.

Description

Technical field: [0001] The invention relates to a bluetooth 4.0 audio receiver with power saving function and a control method. Background technique: [0002] With more and more Bluetooth audio devices, we are more and more accustomed to using Bluetooth wireless connection to play music, but we face two problems: [0003] 1. Most speakers do not support the Bluetooth playback function, even if the sound quality is better, the price is higher or the older speakers may not support the Bluetooth audio playback function; [0004] 2. During the use of audio with Bluetooth playback function, it is usually hoped that the playback device can be connected to Bluetooth to play music, and the Bluetooth device can be disconnected after use to stop, but this requires that the audio power supply is always connected, and the audio is in standby mode. The power is usually higher and consumes more power. Invention content: [0005] The object of the present invention is to provide a Blu...
