It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It is worth noting that in the following description, the "front end" refers to an end relatively close to the ear canal in actual use, and the "rear end" refers to an end relatively far from the ear canal in actual use. The utility model discloses the hardware architecture of the earphone host computer of the bluetooth headset of well main description, its relevant electricity is connected and software, though not carrying out relevant description, but when practical application, all be equipped with relevant electricity and software according to hardware architecture and relevant function needs.
The bluetooth headset in the embodiment comprises a left headset host and a right headset host, wherein the left headset host and the right headset host adopt the same hardware structure but are mirror image structures. As shown in fig. 1, it is a left earphone host corresponding to the left ear in the bluetooth earphone. The hardware structure of the left earphone host comprises an earshell, wherein the earshell comprises an earshell rear cover 11 and an earshell front cover 12. A cavity is formed between the remaining ear shell front cover 12 of the ear shell rear cover 11, a control Circuit Board 2 is installed in the cavity, the control Circuit Board 2 is a mainboard after PCBA (Printed Circuit Board + Assembly, PCB blank Board is installed on SMT, or the whole process of DIP plug-in components), and the control Circuit Board 2 is used for realizing relevant connection and control through various component parts arranged on the control Circuit Board, thereby realizing the work of controlling the earphone.
