Abstract

The utility model discloses a multi-channel Bluetooth earphone with an earphone amplifier. The earphone comprises an earphone support and earmuffs. The earphone support comprises a main support and two auxiliary supports arranged at the two ends of the main support. A chip bin and a guide rail are arranged on the main support; and the chip bin is arranged in the middle of the earphone support. A Bluetooth module and an amplifier module are arranged in the chip bin, the Bluetooth module is used for receiving a digital signal of audio from sound source equipment, and the amplifier module is usedfor converting the digital signal acquired by the Bluetooth module into an analog signal and modulating the analog signal into an electric signal for driving the Bluetooth headset; sound production units are symmetrically arranged in the two earmuffs, and the number of the sound production units arranged in each earmuff is larger than one. The plurality of sound production units form a multi-channel surround sound system.

Description

technical field [0001] The invention relates to the technical field of high-quality earphones, in particular to a multi-channel bluetooth earphone with an earphone amplifier. Background technique [0002] The current bluetooth headset is limited by the size of the headset and the ability of the driving unit, so it can only use a moving coil or moving iron sounding unit, and its sound field and audio-visual performance are not good; at the same time, for flat-panel or The electrostatic sounding unit requires a large driving power and has extremely high requirements on the front-end driving equipment. Usually, an additional amp (headphone amplifier) ​​is required to ensure the sound quality. Therefore, how to free the user from the shackles of the data transmission harness while providing high-quality listening enjoyment has become a difficult problem in the technical field of high-quality earphones. [0003] Thanks to the rapid development of Bluetooth technology and high-ca...
