In the utility model, in the cavity be made up of protecgulum and the bonnet of earphone, loud speaker is set, outwards to sound through the sender of protecgulum by sounding on front side of loud speaker, difference from prior art is, groove is provided with in the rear in lid, the periphery of loud speaker and cavity seal, airtight separate cavities is formed by the rear side of groove, loud speaker, thus better the front side of loud speaker and rear side can be isolated into two spaces of separating, effectively avoid acoustic short circuit problem, better ensure the audio of earphone.
Arrange sound-absorbing material further by described groove, can effectively prevent from forming sound standing wave in separate cavities, avoid sound to be subject to the interference of standing wave, the sound that loud speaker is sent is more clear.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the Novel earphone that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Earphone described in the utility model, mainly can be used for In-Ear Headphones, comprises wired In-Ear Headphones and wireless Bluetooth headsets etc.Its main inventive object is solve the acoustic short circuit problem that earphone of the prior art may occur and the audio improving earphone further.Concrete structure is as shown in Figure 1:
Novel earphone 1 described in the utility model, described Novel earphone 1 comprises protecgulum 11 and bonnet 12, in the cavity 13 be made up of described protecgulum 11 and described bonnet 12, be provided with loud speaker 14, described protecgulum 11 is provided with and the sound sent on front side of described loud speaker can be transmitted to outside sender 110, be provided with groove 120 in described bonnet 12, the peripheral sealing of described loud speaker 14 is fixed in described cavity 13, forms airtight separate cavities 15 by rear side of described groove 120, loud speaker 14.
Concrete, described protecgulum 11 and described bonnet 12 can be plastic material structure, certainly, for needs attractive in appearance, also can use the materials such as wooden shell, aluminum hull.
During the cavity 13 be made up of described protecgulum 11 and described bonnet 12, described protecgulum 11 and described bonnet 12 can be assembled by the mode of socket, and are sealed by colloid.Can certainly helicitic texture be set to, described protecgulum 11 and described bonnet 12 are socketed by helicitic texture.
Wherein, described loud speaker 14, can be arranged at the inwall of described protecgulum 11, also the inwall of described bonnet 12 can be arranged on, when described loud speaker 14 is arranged on described protecgulum 11, can makes just can take out loud speaker 14 when opening cavity 13, being convenient to the maintenance operation to loud speaker 14.Certainly, described loud speaker 14 also can be arranged on described bonnet 12, thus makes the airtight performance of the separate cavities 15 be made up of groove 120, loud speaker 14 better, thus produces better audio.
Described sender 110 can for the multiple apertures of speaking arranged on protecgulum 11, also can a larger sound tube road, for improve described sound hole go out audio fruit, one film can be set in the position of described sound hole, make sound hole to go out sound effective value more mild, avoid because aperture position systematicness not affects audio fruit.
In the execution mode of further optimization, can arrange screen pack 16 at described sender 110 place, can prevent in use procedure, various impurity dust enters in described cavity 13, thus avoid various impurity dust to affect sound go out sound effective value, effectively ensure the stability that loud speaker uses.
The groove 120 arranged in described bonnet 12, its shape can be spherical, square or other shape, as one preferred embodiment in, described groove comprises the first sphere 1201 and the second sphere 1202, and in further preferred embodiment, described first sphere 1201 radius of curvature be 9.7 millimeters, the radius of curvature of the second sphere is 3.2 millimeters.
In addition, it is 3.5 milliliters by a kind of preferred implementation of the volume forming airtight separate cavities 15 on rear side of described groove 120, loud speaker 14.
In the present embodiment, the peripheral sealing of described loud speaker 14 is fixed in described cavity 13, can arrange bulge loop on described protecgulum 11 or bonnet 12, after described bulge loop gluing, can effectively seal fixing with described protecgulum 11 or bonnet 12.
Due to Novel earphone described in the utility model, an airtight space is formed at the rear side of described loud speaker, the sound on rear side of loud speaker and the sound on front side of loud speaker can be made effectively to isolate, avoid the sound wave of the sound wave on front side of loud speaker and rear side to occur acoustic short circuit, that effectively improves loud speaker goes out sound effective value.
Wherein, described acoustic short circuit, when referring to that the vibrating diaphragm of loud speaker moves forwards or backwards, sound wave is anti-phase, causes sound wave to cancel each other, so sound is also very light.
As the further embodiment of the utility model, the groove surfaces arranged in lid is in the rear provided with sound-absorbing material.Arrange sound-absorbing material mainly in order to alleviate and prevent standing wave from producing because standing wave produces " peak " value waveform at certain frequency, make sound deterioration.Sound-absorbing material described in the utility model can be avoided or reduce standing wave, thus sound is not disturbed by standing wave, sounds clean, clear.
Wherein, described sound-absorbing material can be acoustical cotton, open-celled foam plastics etc.
In addition, for ensureing that the wire of loud speaker effectively can connect wire from the rear side of loud speaker, the bottom of described groove 120 is provided with silica gel sealing 1203, and wire is connected with the rear side of described loud speaker by described silica gel sealing.The sealing of separate cavities 15 can well be ensured like this, be also convenient to its dismounting and safeguard.
In addition, the technical scheme of earphone described in the utility model, is used for In-Ear Headphones equipment, therefore, can optimize further, and sender 110 place before described is arranged with earphone cork 17, to improve the comfort of user.
