Problems solved by technology

[0005] However, for the existing hybrid earphones, there are generally complex assembly structures, large cavity structures, and the need for separate controllers, and there is still the possibility of eardrum damage if the air conduction volume is too large

Embodiment Construction

[0031] The present invention will be described below in conjunction with specific embodiments.

[0032] Such as figure 1 As shown, a single-membrane double-sound effect dual-function bone conduction earphone includes an earphone housing 1. The interior of the earphone housing 1 is formed with an accommodating cavity 11 opening toward the ear side or the skull side. The earphone housing 1 is accommodated The opposite side of the opening of the cavity 11 is provided with an audio cable 2 extending into the accommodating cavity 11, and the earphone housing 1 is embedded at the opening of the accommodating cavity 11 and is in close contact with the edge of the opening of the accommodating cavity 11. The non-porous cover 3 seals the opening of the accommodating cavity 11 , and the accommodating cavity 11 is embedded with a vibrating component 4 inside the non-porous cover 3 and an audio signal input component 5 between the vibrating component 4 and the audio cable 2 .

Abstract

The invention discloses a single-membrane double-sound effect dual-function bone conduction earphone. A non-porous cover is embedded in the opening of the accommodation cavity inside the earphone shell. The vibration component and audio signal input component are embedded in the cavity. The audio signal input component includes a hollow voice coil winding and an audio signal connection plate. The vibration component includes a cylindrical magnetic plate, a ring permanent magnet, a cylindrical permanent magnet, and a cylindrical permanent magnet. The opposite polarity surface of the ring-shaped permanent magnet is tightly adsorbed on the cylindrical magnetic conductive plate, and the cylindrical magnetic conductive plate is coaxially seamlessly riveted with a circular vibrating sound film on the opposite side of the cylindrical permanent magnet. Through the above-mentioned structural design, the present invention can obtain double sound effects with bone conduction as the mainstay and air conduction as the supplement, and double functions suitable for both normal and hearing-impaired persons. The design is novel, the structure is simple, and it can effectively reduce the Burden and direct stimulation of the eardrum to relieve premature hearing loss.

Description

technical field [0001] The invention relates to the technical field of audio output equipment, in particular to a single-membrane double-sound effect double-function bone conduction earphone. Background technique [0002] As we all know, there are two ways for humans to listen to sound, specifically: 1. Air conduction (referred to as air conduction), which uses the principle of air vibration transmission. ); 2. Bone conduction (referred to as bone conduction), is to use the principle of transmitting vibration waves like objects to transmit sound waves to the skull of the human body, and then directly transmit the sound waves to the internal ear nerves through the skull without the need for vibration of the eardrum. [0003] People usually listen to the sound through the eardrum to sense the air-conducted sound waves and then transmit them to the internal auditory organs. Because the eardrum is relatively fragile, although it can sense delicate high-frequency sounds, it is di...
