Abstract
The utility model relates to a bone conduction earphone and particularly relates to a bone conduction earphone which has the advantages of rich bass, high conversion efficiency of a motor and high definition. The bone conduction earphone comprises a pair of spring units, an inner magnetic conduction ring, an outer magnetic conduction ring, top magnetic conduction rings, a bottom magnetic conduction ring, a circuit board, and voice coils, a central shaft body and an earphone shell which are welded on the circuit board. The inner magnetic conduction ring, the outer magnetic conduction ring, the top magnetic conduction rings and the bottom magnetic conduction ring are combined together to form a magnetic circuit part of the bone conduction earphone; the magnetic circuit part is elastically connected onto the shell through the central shaft body and the spring units; and the circuit board and the voice coils welded on the circuit board are rigidly and fixedly connected to the shell. Stereo current signals of a sound source flows through the voice coils and generate an alternating electromagnetic force to push the magnetic circuit part to generate vibration, the vibration source further causes the earphone shell to vibrate through the pair of spring units, the induced vibration is transmitted through the human skin and bones, and sound waves are directly transmitted to auditory nerves.
Description
Technical field
The utility model relates to a kind of bone conduction type earphone, and especially a kind of bass is abundant, motor conversion efficiency height, bone conduction type earphone that definition is high.
Background technology
Traditional earphone utilizes electromagnetic force driven diaphragm to produce the piston motion, sounds with the air coupling.This sound is transmitted to the auditory nerve of brain by people's ear-drum, and people call conductance type earphone to this class earphone usually.For the user who uses conductance type earphone, their ear-drum is subjected to the bump of air-flow always, goes down for a long time, may damage ear-drum, causes hearing to descend.In order to address this problem, people's utility model bone conduction type earphone, this earphone is converted to vibration signal with the signal of telecommunication, by contacting with skin and the bone of human body, as media sound wave is directly transferred to the auditory nerve of brain with solid (non-air).Because have the effect of protection ear-drum, bone conduction type earphone obtains people's favor.But bone conduction earphone in the market (mainly from Japan and Korea S), the manufacturing process complexity, the price height makes those interested clients hang back.In addition, its tonequality is definition especially, also has many places that need improvement.
Summary of the invention
In order to overcome the shortcoming of existing bone conduction type earphone, the utility model provides that a kind of bass is abundant, motor conversion efficiency height, bone conduction type earphone that definition is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of bone conduction type earphone, it is characterized in that, comprising: an auxiliary spring unit, internal magnetic ring, outer magnetic ring, top magnetic guiding loop, bottom magnetic guiding loop, circuit board and be welded on voice coil loudspeaker voice coil, middle part axis body, earphone case on the circuit board; Described internal magnetic ring, outer magnetic ring, top magnetic guiding loop, bottom magnetic guiding loop are combined the magnetic circuit part that forms bone conduction type earphone; Described magnetic circuit partly by middle part axis body, spring unit, is elastically connected on the shell; Described circuit board and the voice coil loudspeaker voice coil that is welded on the circuit board rigidly fix on the shell.In the design that the utility model discloses, the stereo current signal of source of sound flows through voice coil loudspeaker voice coil, produce the electromagnetic force of an alternation, promote magnetic circuit and partly produce vibration, this vibration source is by an auxiliary spring unit, cause that further earphone case produces vibration, the vibration of inducing is directly transferred to auditory nerve to sound wave by skin and the osteoacusis of human body.

Embodiment
With reference to Fig. 1, a kind of bone conduction type earphone comprises: an auxiliary spring unit 11a and 11b, internal magnetic ring 12a, outer magnetic ring 12b, top magnetic guiding loop 13a and 13b, bottom magnetic guiding loop 13c, circuit board 14 and be welded on voice coil loudspeaker voice coil 15, middle part axis body 16, earphone case 17 on the circuit board; Described internal magnetic ring, outer magnetic ring, top magnetic guiding loop, bottom magnetic guiding loop are combined the magnetic circuit part that forms bone conduction type earphone; Described magnetic circuit partly by middle part axis body, spring unit, is elastically connected on the shell; Described circuit board and the voice coil loudspeaker voice coil that is welded on the circuit board rigidly fix on the shell.In the design that the utility model discloses, the stereo current signal of source of sound flows through voice coil loudspeaker voice coil, produce the electromagnetic force of an alternation, promote magnetic circuit and partly produce vibration, this vibration source is by an auxiliary spring unit, cause that further earphone case produces vibration, the vibration of inducing is directly transferred to auditory nerve to sound wave by skin and the osteoacusis of human body.
Magnetic and two permanent magnets of outer magnetic in the magnetic Circuit Design that the utility model discloses comprises provide a highdensity magnetic field and stronger electromagnetic actuation force, greatly improve the motor conversion efficiency height of earphone, have enriched its bass effect.Adopt an auxiliary spring unit, be separately fixed at upper end and the lower end of middle part axis body, avoid those undesired rocking vibration and noises, greatly improved operating efficiency and the definition of earphone.
