Granted publication comprises earphone body, loudspeaker, interior clamshell and earplug number for the Chinese utility model of CN201114716Y discloses a kind of earphone and telephone transmitter thereof that ceramic inner casing is put that have, and the earphone body is provided with holding part, and loudspeaker are placed in the earphone holding part; Interior clamshell is made by ceramic material, and cover cap is on the earphone body.This earphone has reduced distortion rate, makes tonequality obtain raising to a certain degree.Yet because it has only partly adopted ceramic material at interior clamshell, its distortion rate is still higher, and on the earphone body tone chamber is not set, and its bass and high pitch performance are still not good enough, the middle pitch muddiness; And owing to after the earplug of earphone inserts ear, forms airtight relatively space, the air-flow that the loudspeaker vibration produces directly impacts ear-drum, injures ear easily, and the while has also influenced the performance of earphone tonequality.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, but provides a kind of distortion rate low, and high pitch is loud, middle pitch is clear and melodious, bass is simple and honest strong and be difficult for the ceramic earphone of infringement ear.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of ceramic earphone is characterized in that: comprise
The pottery auricular concha is provided with the tone chamber in the auricular concha;
The pottery cover, cover and the auricular concha formation cavity that is connected, cover is provided with the fixedly groove position of loudspeaker towards an end of auricular concha, and an end of auricular concha is provided with voice guide hole dorsad, forms resonator between groove position and the voice guide hole;
Loudspeaker, these loudspeaker are built in the cavity, and ceramic cover groove position is fixed in its front portion, and the rear portion places in the tone chamber.
Described ceramic auricular concha is provided with cannelure, and the annular protrusion of this cannelure and ceramic cover is connected.
Described ceramic cover resonator is made up of cylindrical cavity and round platform cavity, is provided with steam vent on the frustum cone side that axially is greater than 45 ° of angles.
Described auricular concha axially is provided with the steam vent that communicates with the tone chamber in vertical top.
Described ceramic cover extends axially and forms the earplug installation portion, and voice guide hole is located at a core position; Be provided with the installation draw-in groove on installation portion, flexible earplug is socketed on to install in the draw-in groove by its inner socket part and is connected with cover; Flexible earplug is established the axially extending bore that communicates with voice guide hole.
Described loudspeaker comprise ceramic main body and phonation unit, and phonation unit is fixedly arranged on the ceramic main body.
Described ceramic auricular concha is provided with support arm, is provided with the through hole that supply lines enters the tone chamber in this support arm.
Described installation portion voice guide hole end face is provided with the groove that Air Filter is installed, and the Air Filter edge is put wherein.
Described auricular concha rear portion is provided with a core through hole, is provided with the groove of placing Air Filter at the through hole port, and the Air Filter edge is put wherein.
Described flexible earplug is made by silica gel, is the mushroom that cooperates with earhole.
Owing to adopted said structure, ceramic earphone of the present utility model greatly reduces the distortion rate of earphone because auricular concha and cover have all adopted ceramic material; In auricular concha, be provided with the tone chamber, and be provided with through hole in auricular concha rear end axle core, at the steam vent that position perpendicular to axial direction is provided with, make the performance of earphone bass simpler and more honest, more strong and powerful, by the setting of through hole and steam vent, reduce simultaneously because of the too high interference that causes of tone chamber's internal gas pressure; The resonator of being made up of cylindrical cavity and round platform cavity is set on cover, make that middle pitch performance is clearer and more melodious, high pitch is louder, simultaneously also with the frustum cone side that axially is greater than 45 ° of angles on be provided with steam vent, avoid air-flow to enter ear and cause discomfort, reduce of the impact of the air-flow of phonation unit vibration production, also reduce the interference of high pressure tonequality to ear-drum.
