The utility model content
At the prior art deficiency, the utility model proposes a kind of earphone of convertible cavity, be intended to solve a earphone and can only limit to a kind of structure Design, produce a kind of problem of single acoustical quality.
The technical scheme that the utility model proposes is:
A kind of earphone of convertible cavity comprises the back cavity shell, matching with described back cavity shell forms back cavity seat, horn hood and the ear muff of cavity, and described cavity shell afterwards is provided with through hole; Also comprise and be arranged in the cavity shell of described back and the baffle plate that can make described through hole sealing or open.
Further technical scheme can also be, described through hole is the last circular hole of array symmetric arrays, with described on the described baffle plate of circular hole opposite position be provided with down circular hole.
Further technical scheme can also be, described baffle plate is articulated on the cavity shell of described back.
Further technical scheme can also be, the described big 0.01 ~ 0.5mm of circular hole that goes up of the radius ratio of described circular hole down.
Further technical scheme can also be, the described circular hole of going up is provided with four groups and symmetric arrays, and described circular hole down is corresponding with four groups of described circular hole positions of going up.
Further technical scheme can also be, also comprise the rotating mechanism that makes described baffle plate rotation, described rotating mechanism comprises screw, turn-button and screens device, and described screw passes described back cavity shell and described screens device, described turn-button, described baffle plate are axially fixed on the cavity shell of described back.
According to above-mentioned technical scheme, the utility model beneficial effect: can form an open or enclosed cavity by rotating described baffle plate, thereby can allow the consumer according to different audition hobby and different music track free adjustment cavity body structures, listen to perfect audio.
Owing to the utlity model has above-mentioned characteristics and advantage, can be applied in the product such as earphone for this reason.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, 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 explaining the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, a kind of earphone of convertible cavity comprises back cavity shell 1, matching with described back cavity shell 1 forms back cavity seat 2, horn hood 6 and the ear muff 8 of cavity, and described cavity shell 1 afterwards is provided with through hole; Also comprise and be arranged in the described back cavity shell 1 and the baffle plate 3 that can make described through hole sealing or open.
Wherein, the shape of described through hole and size can be arbitrarily, only need guarantee that described baffle plate 3 can make described through hole sealing or open getting final product, but for from attractive in appearance and process aspect such as simple and easy and consider, described through hole is symmetrical arranged circular hole 11 on four groups for the periphery at described back cavity shell 1, in order to allow cavity reach open effect better, the described circular hole 11 of going up of each group adopts the 4X4 gradual change to arrange, and the open area that can increase open cavity like this can strengthen the aesthetic feeling of vision again.
In order to cooperate described back cavity shell 1 to form sealing or open cavity, on the described baffle plate 3 with described on circular hole 11 opposite positions be provided with down circular hole 31, when open cavity, be not blocked in order to ensure the whole described circular hole 11 of going up, described circular hole 31 down should be more than or equal to the described circular hole 11 of going up, in order to reduce the requirement of precision, the described circular hole 11 big 0.01 ~ 0.5mm that go up of the radius ratio of described circular hole 31 down.
Described baffle plate 3 is articulated on the cavity shell 1 of described back, and described baffle plate 3 can be by rotation mode sealing or the open described circular hole 11 of going up; A kind of like this earphone of convertible cavity also should comprise the rotating mechanism 4 that can make described baffle plate 3 rotations, described rotating mechanism 4 comprises screw 41, turn-button 42 and screens device 43, described screw 41 passes described back cavity shell 1 and described screens device 43, described turn-button 42, described baffle plate 3 is axially fixed on the cavity shell 1 of described back, described baffle plate 3 closely pastes mutually with described back cavity shell 1, described baffle plate 3 is the POM material, can reduce friction when rotating; When the user firmly reverses described turn-button 42, described screens device 43, described baffle plate 3, described screw 41 are along with described turn-button 42 rotates and rotates, but described back cavity shell 1 keeps motionless, the internal diameter of described back cavity shell 1 should be bigger than described screw 41 external diameters, described turn-button 42 adopts curved-surface structure, make things convenient for the user to exert all one's strength and skidding to occur, described turn-button 42 and described baffle plate 3 be by described screw 41 fixing and described screens devices 43 location, described turn-button 42 occurs when avoiding occurring rotating described turn-button 42 and do not rotate or skidding.
