Title: BONE CONDUCTION EARPHONE AND METHOD OF MANUFACTURING SAME
Abstract:
Disclosed are a bone conduction earphone and a method of manufacturing same. The earphone comprises an earphone casing (10), wherein the casing (10) surrounds a cavity; a frequency divider and a metal speaker are provided in the cavity; an inner wall of the casing (10) is provided with a bone conduction speaker; the frequency divider outputs an audio signal to the bone conduction speaker; and the frequency divider outputs a full-range frequency signal, a high-frequency signal, a mid-frequency signal or a low-frequency signal to the metal speaker. The method of manufacturing the earphone comprises: manufacturing an earphone casing (10), the casing (10) comprising a custom-made outer casing (11), and the custom-made outer casing (11) having an open end; manufacturing a cover plate (20) fixed outside the open end, at least a part of the custom-made outer casing (11) being attached to an ear canal; providing a circuit board (21) on the cover plate (20), a frequency divider being provided on the circuit board (21), and a bone conduction speaker being provided on an inner wall of the custom-made outer casing (11); and providing a metal speaker in the custom-made outer casing (11), the frequency divider and the bone conduction speaker being electrically connected, and the frequency divider being electrically connected to the metal speaker.
