Bluetooth headset and volume self-adaption method thereof

Abstract

The invention discloses a Bluetooth headset and a volume self-adaption method thereof. The volume self-adaption method comprises the following steps: S1, external environment noise is detected by using a microphone; S2, the earphone IC picks up a noise signal carrying external environment noise from a microphone, and analyzes the size of the noise signal to judge the current external environment noise level; and S3, according to the current noise level, the earphone IC outputs volume energy of a corresponding level to act on the loudspeaker, and the higher the external environment noise levelis, the higher the volume energy applied to the loudspeaker by the earphone IC is; on the contrary, when the noise level of the external environment is lower, the volume energy applied to the loudspeaker by the earphone IC is lower, namely the outside is very noisy, the volume of the earphone can be automatically increased, and when the outside is very quiet, the volume of the earphone can be automatically reduced, so that the volume self-adaptive effect is achieved, and the listening experience and the product experience of a user are greatly improved.

Description

technical field [0001] The invention relates to the technology in the field of earphones, in particular to a bluetooth earphone and a volume adaptive method thereof. Background technique [0002] At present, for existing Bluetooth headsets, the fixed sound effects that users experience are determined by the options and debugging of the headset at the R&D end. The noise floor problem is largely determined by the environment. The debugging engineer of the research and development may calibrate the noise floor in an office environment or in a special anechoic room. The noise floor problem is affected by individuals with sensitive ears. In many cases, in order to meet the needs of volume and timbre, it leads to audible background noise that consumers experience in common late night or relatively quiet environmental scenes.

[0002] At present, for existing Bluetooth headsets, the fixed sound effects that users experience are determined by the options and debugging of the headset at the R&D end. The noise floor problem is largely determined by the environment. The debugging engineer of the research and development may calibrate the noise floor in an office environment or in a special anechoic room. The noise floor problem is affected by individuals with sensitive ears. In many cases, in order to meet the needs of volume and timbre, it leads to the audible background noise that consumers experience in common late night or quieter environmental scenes.
