Dual-film dual-conduction multi-channel earphone

Abstract

The invention discloses a dual-film dual-conduction multi-channel earphone. Each earphone is provided with a metal base, a cylindrical yoke, cylindrical permanent magnets, and a component, wherein the cylindrical yoke is arranged in the center of the metal base; the cylindrical permanent magnets are arranged outside the yoke in a coaxial radial order; the component consists of a coil winding and the cylindrical yoke; a spherical sound film is bonded on the upper part of the cylindrical yoke seamlessly; the other side of the metal base is connected with another base through a screw; a spring gasket is arranged between a circular vibrating diaphragm in the middle of two bases and each base; a vibrating conducting cylinder is fixedly arranged at the periphery of the outer diameter of the circular vibrating diaphragm and on the outer side which is close to the component and is not contacted with the component; the other end of the vibrating conducting cylinder is a circular buffer gasket; the spherical sound film and the circular vibrating diaphragm conduct the sound to the auditory nerve through two media of air and skull so as to generate sense of hearing. On the basis of effectively protecting the hearing of a user, the multi-channel earphone maintains certain stimulus intensity to the cochlea, has good acoustical effect, and is beneficial for the physical and mental health of a listener.

Description

technical field [0001] The invention relates to an earphone with a novel structure, specifically, a double-membrane, double-conduction multi-channel earphone, which belongs to the technical field of audio output equipment. Background technique [0002] When human beings receive external sound signals, there are two ways: one is air conduction, that is, sound waves vibrate the human eardrum, stimulate the cochlea through the conduction of the auditory ossicles, and then conduct to the brain through the auditory nerve to produce hearing. The other is bone conduction. Vibrating sound waves first transmit signals to the auditory ossicles through the skull, which also stimulates the cochlea, and then conducts to the brain through the auditory nerve to produce hearing. [0003] At present, in order to reduce the maximum sound pressure of earphone-specific speakers, relevant manufacturers have adopted various hearing protection and ear protection technologies. For example, manufact...

Problems solved by technology

In this way, although the multiple channels are sounding independently, for the eardrum, what it hears is still an approximate mixed sound source, so the effect is not good

[0005] The disadvantage of traditional bone conduction headphones is that the sound range is not wide enough, especially in the high frequency part.
