Abstract

The invention discloses a Bluetooth headset mainboard with a noise reduction structure and capable of shielding noise, and relates to the field of Bluetooth headset mainboards, the Bluetooth headset mainboard comprises a mainboard body and a low-noise heat dissipation mechanism, a heat dissipation roller is transversely arranged on the front surface of the mainboard body in a penetrating manner, and the low-noise heat dissipation mechanism is mounted in the middle of the front surface of the heat dissipation roller. The technical problems that when an existing Bluetooth headset main board works, due to interference of various kinds of noise in the external environment, sound needing to be received can be interfered, the noise reduction effect cannot meet the requirement, and meanwhile the defect that the operation efficiency of the main board is affected due to the poor heat dissipation effect exists are solved. According to the Bluetooth headset mainboard with the noise reduction structure and capable of shielding noise, the sound receiving device is independently arranged on the right side of the mainboard, the partition plate made of the copper-nickel-copper material is attached to the left side of the shell, mutual interference between the sound receiving device and other signal sources is effectively shielded, and the problems that an existing Bluetooth headset mainboard has call noise, is poor in GPS antenna signal and the like are solved.

Description

technical field [0001] The invention relates to the field of a bluetooth earphone mainboard, in particular to a bluetooth earphone mainboard with a noise reduction structure capable of shielding noise. Background technique [0002] Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Since the Bluetooth headset came out, it has been a good tool for mobile business people to improve efficiency. The motherboard is an indispensable and important component to control the normal operation of the Bluetooth headset. [0003] The common problems of the existing bluetooth headset mainboard are: when the existing bluetooth headset mainboard is working, due to the interference of various noises in the external environment, it will cause interference to the sound that needs to be received, which will lead to noise reduction. The role of the problem does not meet the requirements, but also has ...
