Abstract

An earphone comprises a main control chip, a stereo digital earphone amplifier powered by a single power supply, and a loudspeaker, wherein the main control chip obtains an audio signal to be processed, decodes the audio signal to be processed to obtain a first audio signal, carries out mirroring processing on the first audio signal to obtain a second audio signal, and transmits the first audio signal and the second audio signal to the stereo digital earphone amplifier; and the stereo digital earphone amplifier performs digital-to-analog conversion and amplification on the first audio signal and the second audio signal to respectively obtain a third audio signal and a fourth audio signal, and transmits the third audio signal and the fourth audio signal to the loudspeaker to drive the loudspeaker. According to the earphone, the driving voltage and the output power of the loudspeaker can be improved under the condition that power is supplied by a single power supply, the complex matching of an earphone circuit structure is avoided, and the cost is also prevented from being increased.

Description

technical field [0001] The present application relates to the technical field of earphones, and more specifically relates to an earphone. Background technique [0002] At present, Bluetooth headsets such as true wireless stereo headsets (TWS) are usually powered by a single power supply, and the speaker is directly driven by the Bluetooth chip or a headphone amplifier with a single power supply is added to drive the speaker. The voltage and power of the driving speaker are affected by the voltage of the single power supply itself. Size restrictions. [0003] In order to increase the voltage and power of driving the loudspeaker, the existing solution is generally to design the earphone as a dual power supply. However, such a method has to change the structure of the earphone single power supply, and increases the cost. Contents of the invention [0004] This application was made in order to solve the above-mentioned problems. According to one aspect of the present applic...
