Earphone core structure of earphone

Abstract

The invention discloses an earphone core structure of an earphone. The earphone core structure comprises a battery and an earphone core, the structure is characterized in that the earphone core comprises a radio frequency module, a battery module, an operational amplifier module, an audio module and a charging module; the five modules are electrically connected with one another and electrically connected with the battery, and the battery is used for supplying power; the radio frequency module, the battery module, the operational amplifier module and the battery are overlapped and installed on a connecting piece to form a whole; the additional audio module and the charging module are free from connecting with the connector due to the need of being arranged in specific positions; after installation, the radio frequency module of the earphone core structure is located at the endmost position, and the position between the radio frequency module and the connecting piece is empty, the vertical distance between the radio frequency module and the module closest thereto is greater than 3mm, so that a clearance environment can be formed around the radio frequency module, excellent radio frequency signals can be guaranteed, and the electromagnetic interference is effectively reduced.

Description

technical field [0001] The invention relates to an electrical structure of a wearable electronic device, in particular to a core structure of an earphone. Background technique [0002] With the development of science and technology, wireless earphones gradually appear in people's lives. Wireless earphones are favored by people because of their convenient portability, which solves the various inconveniences of traditional wired earphones. Existing wireless earphones are generally single-ear wireless earphones, which have low requirements for signal and various radio frequency devices, so the internal electrical structure design is relatively random, and the circuit modules and batteries are only randomly placed and fixed, or randomly stacked. Together, the sensitive radio frequency signal cannot be played well. It can be used for single-ear wireless earphones, but for binaural wireless earphones, the electromagnetic interference is serious and the signal is poor. Contents o...

Existing wireless earphones are generally single-ear wireless earphones, which have low requirements for signal and various radio frequency devices, so the internal electrical structure design is relatively random, and the circuit modules and batteries are only randomly placed and fixed, or randomly stacked. Together, the sensitive radio frequency signal will not be played well. It can be used for single-ear wireless earphones, but for binaural wireless earphones, the electromagnetic interference is serious and the signal is poor.
