Single-film bone conduction earphone with double functions and double sound effects

Abstract

The invention discloses a single-film bone conduction earphone with double functions and double sound effects. A cover without holes is mounted at the opening of an accommodating cavity inside an earphone shell in an embedded mode; an audio cable is mounted and arranged on the opposite side, at the position of the opening of the accommodating cavity, of the earphone shell; a vibration assembly and an audio signal input assembly are mounted in the accommodating cavity in the embedded mode; the audio signal input assembly comprises hollow voice coil windings and an audio signal connecting plate; the vibration assembly comprises a cylinder-shaped concentrating flux plate, annular permanent magnets and a cylinder-shaped permanent magnet; heteropolar surfaces of the cylinder-shaped permanent magnet and the annular permanent magnets are tightly adsorbed to the cylinder-shaped concentrating flux plate; the cylinder-shaped concentrating flux plate is coaxially and seamlessly riveted to a circular vibration sound film on the opposite side of the cylinder-shaped permanent magnet. Through the structural design, the earphone can obtain double sound effects by taking bone conduction as the principal thing and taking air conduction as the auxiliary thing, and has double functions that the earphone is suitable for both hearing normal people and hearing handicapped; the earphone is novel in design and simple in structure, and can effectively alleviate burden and direct stimulation for eardrums to relieve early ear 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...

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
