Abstract
The utility model relates to an earphone, especially relates to a length adjustable earphone structure, comprising a front cavity, a silica gel sleeve and a back cavity. The front cavity possesses an extending end, and at least two grooves are arranged on the outer side wall of the extending end; the silica gel sleeve is fastened in the grooves, and the back cavity is connected with the other end of the front cavity. In the utility model, by arranging the extending end on the front cavity, and arranging the at least two grooves on the outer side wall of the extending end, the effect that the silica gel sleeve is fastened and fixed via the grooves is achieved; because the silica gel sleeve can be fastened at different positions of the grooves, the length adjustable beneficial effect of the utility model is achieved; and because the volumes of an enclosed space formed by the silica gel sleeve, the front cavity and a user auricle are different when the silica gel sleeve is fastened at the different positions of the grooves, the length adjustable earphone structure of the utility model enables the different sound effects to be realized in accordance with that the silica gel sleeve is fastened at the different positions of the grooves.
Description
Technical field
The utility model relates to earphone, relates in particular to a kind of length adjustable Headphone structure.
Background technology
Earphone is a kind of portable pronunciation device, and earphone is classified according to its transducing mode, mainly contain moving-coil mode, moving iron mode, electrostatic and etc. magnetic-type.Separating type is classified on the structure, can be divided into semi open model and closed.From wearing formal classification ear type is arranged then, ear suspension type, In-Ear and head-type.Weigh earphone and can estimate the method for audio amplifier with some, but the sense of hearing of earphone is different with audio amplifier that the sound wave that audio amplifier sends is decayed in air, interfered, with people's head and ear interaction, and the sound of earphone is directly to get into ear.
Audio is meant the effect by the sound manufacturing, is meant the sense of reality, atmosphere or drama message into the enhancement scene, and is added on noise or the sound on the vocal cords.So-called sound has then comprised musical sound and effect sound.Comprise digital audio, EAX etc.
At present, the headset main body of selling on market structure is by ante-chamber, back cavity, silica gel sheath is formed, ante-chamber go up groove of processing, make silica gel sheath and the ante-chamber can fitting tight, can not be prone to come off by pine.Like this each earphone from the front end of silica gel sheath to after the distance of afterbody just fixing; The people that can not guarantee different ear sizes wears comfortable; Ante-chamber in addition, silica gel sheath and people's auricle can only produce the structure of a single sealing, and the resonance that sound wave produces is single; The acoustical quality of one set of headphones is also just a kind of, can not change.
The utility model content
The goal of the invention of the utility model is to provide a kind of length, audio adjustable earphone structure.
In order to realize the foregoing invention purpose, the technical scheme of the utility model is:
A kind of length adjustable Headphone structure comprises ante-chamber, silica gel sheath; Said ante-chamber has elongated end, on the lateral wall of elongated end, offers at least two grooves; Said silica gel sheath is buckled in the said groove.
Optional, also comprise back cavity; Said back cavity connects the other end of said ante-chamber.
The utility model is designed with elongated end with ante-chamber; And offer at least two grooves at the lateral wall of elongated end; Realize that through groove snap fit lives the effect of silica gel sheath, and silica gel sheath can be buckled in the groove of diverse location, realizes the length-adjustable beneficial effect of the utility model.Because silica gel sheath is when being buckled in the groove of diverse location, the enclosure space volume that silica gel sheath, ante-chamber and user's auricle are formed into is also inequality, makes the utility model can realize the effect of different audios according to the groove that silica gel sheath is snapped in diverse location.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
A kind of overall structure sketch map that Fig. 1 provides for the utility model embodiment 1.
Embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Embodiment 1:
As shown in Figure 1, present embodiment discloses a kind of length adjustable Headphone structure, has comprised ante-chamber 100, silica gel sheath 200, back cavity 300, loudspeaker 400; Ante-chamber 100 has an elongated end, on the lateral wall of elongated end, offers two grooves (110,120); Silica gel sheath 200 can be buckled in groove 110 or the groove 120; Back cavity 300 connects the other end of ante-chamber 100, and loudspeaker 400 are installed in the junction of back cavity 300 and ante-chamber 100.
Present embodiment offers groove (110,120) on the lateral wall of the elongated end of ante-chamber 100, silica gel sheath 200 alternatives are buckled on groove 100 or the groove 120 when making present embodiment, realizes the effect of earphone adjustable in length thus.
To explain with the actual use of present embodiment below:
When wearer's ear hour; Need earphone length (front end of silica gel sheath 200 is to the tail end distance of back cavity 300) weak point to guarantee to wear comfortable; Just silica gel sheath 200 is contained on nearer groove 110 positions of ante-chamber 100; When wearer's earphone is big, just silica gel sheath 200 is contained on ante-chamber 100 groove 120 positions far away, wear comfortable with assurance.
Embodiment 2:
Present embodiment is with embodiment 1 different place: the elongated end of ante-chamber 100 offers three grooves.Other structures are consistent with embodiment.
Present embodiment has increased the quantity of groove, and there are more more options the position that makes silica gel sheath install, and produced simultaneously audio effect is more varied, makes present embodiment have more practicality.
What need to specify is that the quantity of groove can increase and decrease according to actual demand.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
