Method for adaptive adjustment of volume of WIFI sound box

Abstract

The invention discloses a method for adaptive adjustment of the volume of a WIFI sound box. When audio data are played, the current playing volume is obtained and compared with a preset volume threshold value, and is adjusted towards the preset volume threshold value according to a comparison result, so that an absolute value of a difference value between the current playing volume and the preset volume threshold value is smaller than or equal to a preset volume error threshold value. The method for adaptive adjustment of the volume of the WIFI sound box is simple in design and convenient to use, can automatically adjust the volume, and saves worry and labor.

Description

technical field [0001] The invention relates to the field of speaker control, in particular to a method for adaptively adjusting the volume of a WIFI speaker. Background technique [0002] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. [0003] The reason why the speaker exists in the box is mainly to prevent the sound wave signals on the front and back of the speaker diaphragm from directly forming a loop, so that only the high and medium frequency sounds with a small wavelength can be transmitted, while other sound signals are superimposed and canceled Lost. [0004] The physical model of the speaker is to open a hole in an infinite rigid baffle and install the speaker, so that the sound signals on the front and back of the spe...

Problems solved by technology

[0006] The ensuing problem: due to the problem of atmospheric pressure after the speaker is sealed, the larger the speaker box is, the better it is to restore the low-frequency sound. Therefore, the volume of the general speaker is a compromise calculated based on the speaker size of the mid-bass unit.

[0015] Existing speakers are generally connected by wires, which is very inconvenient when the space is limited or the speakers need to be moved frequently

[0016] In addition, the existing speakers generally need to manually adjust the volume of the sound. Since the speakers directly play the received sound data, sometimes the volume of the original data is very high, and sometimes it is very low, which requires constant manual adjustment, which is very troublesome.
