Adaptively volume-adjusting WIFI sound box

Abstract

The invention discloses an adaptively volume-adjusting WIFI sound box. The adaptively volume-adjusting WIFI sound box comprises a WIFI module, a control module, a storage module, a sound sensor, an audio decoding module, an amplifying module and a loudspeaker. The control module is connected with the WIFI module, the storage module, the sound sensor, the audio decoding module and the amplifying module. The loudspeaker is connected with the audio decoding module through the amplifying module. The storage module is used for storing playing protocols. The control module comprises a WIFI control unit, a sound comparing unit and a volume adjusting unit. The WIFI control unit is used for receiving audio data of the WIFI module according to the playing protocols in the storage module. The sound comparing unit is used for comparing a received currently-playing volume with a preset volume threshold. The volume adjusting unit is used for controlling the amplifying module to adjust the playing volume according to the comparison result of the sound comparing unit. The adaptively volume-adjusting WIFI sound box with a simple structure is convenient to use and requires no wired connection. The WIFI sound box which achieves automatic volume adjustment is labor-saving and worry-saving.

Description

technical field [0001] The invention relates to the field of sound boxes, in particular to a WIFI sound box for adaptive volume adjustment. 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 speaker will not form ...

AI Technical Summary

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.
