Specific embodiment

For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match Attached drawing is closed to be explained.

The design of the utility model most critical is: being provided with damping hole and vent grooves on sound chamber BOX shell, damps Hole is connect with vent grooves, and MESH screen component is pasted on the top of vent grooves.

Before this, the technical solution of the utility model in order to facilitate understanding, for English involved in the utility model Abbreviation, equipment etc. are described as follows:

(1), BOX and MESH: in the present invention, BOX is the box body for installing loudspeaker, and MESH net is loudspeaker nethike embrane.

Please refer to Fig. 1 to Fig. 4, a kind of sound chamber BOX structure, including sound chamber BOX shell and MESH screen component, the sound chamber Damping hole and vent grooves are provided on BOX shell, the damping hole is connect with the vent grooves, the MESH screen component It is pasted on the top of the vent grooves.

Wherein, sound chamber BOX shell formed a cavity, pass sequentially through damping hole, vent grooves and MESH screen component into The ventilative pressure release of row, thus changes the length of vent grooves to change amplitude effect, to change loudspeaker performance.

As can be seen from the above description, the utility model has the beneficial effects that: also being opened up on the damping hole of sound chamber BOX shell There are vent grooves, MESH screen component is pasted on to the top of vent grooves, so that the outlet length in growth drag hole, makes loudspeaker It can be more preferable；The outlet length of damping hole can be adjusted by adjusting the length of vent grooves simultaneously, i.e. adjustment space is big, MESH The top of vent grooves is arranged in screen component, i.e., in surface of shell, is also convenient for being confirmed whether missing.

Further, the damping hole is connect with one end of the vent grooves.

As can be seen from the above description, damping hole is equal with the connection of one end of vent grooves and the width of the two, so that damping hole The gas of the inside is flowed only along a direction, to form preferably ventilative pressure release effect.

As can be seen from the above description, MESH net is pasted by double-sided adhesive, so that in MESH net when there is quality problem, only Need replacing MESH screen component, i.e., rework operation is relatively simple and the bad material cost done over again is lower.

Further, the venthole is located at the top of one end of the vent grooves.

As can be seen from the above description, one end of venthole and vent grooves connects, so that the gas edge inside vent grooves The outflow of direction, to form preferably ventilative pressure release effect.

It is positioned as can be seen from the above description, setting is fluted, in order to paste MESH screen component, to improve production Efficiency.

As can be seen from the above description, i.e. MESH screen component is not the upper surface for protruding from sound chamber BOX shell, it is not easy to be missed by other Operation is damaged.

Seen from the above description, the specific embodiment of a kind of MESH net groove, damping hole and vent grooves is provided, is made It is more preferable to obtain loudspeaker performance.

Please refer to Fig. 1 to Fig. 4, the embodiments of the present invention one are as follows:

A kind of sound chamber BOX structure, including sound chamber BOX shell 1 and MESH screen component 2 are provided with resistance on sound chamber BOX shell 1 Buddhist nun hole 11, vent grooves 12, first edge 15 and MESH net groove, MESH screen component 2 include MESH net 21 and double-sided adhesive 22, Venthole 23 is offered on double-sided adhesive 22, MESH net groove includes square groove 13 and arc-shaped slot 14.

Wherein, one end of vent grooves 12 is connect with damping hole 11, and venthole 23 is located at the other end of vent grooves 12 Top, and the aperture of damping hole 11 is equal with the width of vent grooves 12, the aperture of venthole 23 is greater than the width of vent grooves 12 Degree.

Wherein, MESH net groove is consistent with the shape of MESH screen component 2 and the depth of MESH net groove is greater than MESH net group The thickness of part 2, MESH screen component 2 are pasted in MESH net groove.

Wherein, square groove 13 is located in first edge 15, on square groove 13 far from first edge 15 one end with it is arc-shaped Slot 14 connects, and damping hole 11 is located at the center of arc-shaped slot 14, and vent grooves 12 are since damping hole 11 towards first edge 15 Direction extend, herein, 12 shape of vent grooves is not defined as linear type, is also possible to S type, screw type etc., and logical The length of gas groove 12 is less than the distance that damping hole 11 arrives first edge 15.

Wherein, in other equivalent integers, the position of damping hole 11 can be any position on MESH net groove On, the aperture of damping hole 11 can also be unequal with the width of vent grooves 12；The length of vent grooves 12 can be according to reality Demand is configured, and the aperture of venthole 23 might be less that the width equal to vent grooves 12, venthole 23 and vent grooves As long as 12 have connection.

Wherein, in other equivalent integers, as long as MESH screen component 2 is pasted in MESH net groove, so MESH screen component 2 can also be pasted by other backing materials or self adhesive material.

In conclusion a kind of sound chamber BOX structure provided by the utility model, is also opened on the damping hole of sound chamber BOX shell Equipped with vent grooves, MESH screen component is pasted on to the top of vent grooves, so that the outlet length in growth drag hole, makes loudspeaker Performance is more preferable；The outlet length of damping hole can be adjusted by adjusting the length of vent grooves simultaneously, i.e. adjustment space is big, The top of vent grooves is arranged in MESH screen component, i.e., in surface of shell, is also convenient for being confirmed whether missing；It is glued by double-sided adhesive MESH net is pasted, so that in MESH net when there is quality problem, it is only necessary to replace MESH screen component, i.e. rework operation more The simple and bad material cost done over again is lower；Be arranged it is fluted positioned, in order to paste MESH screen component, to mention High efficiency, i.e. the utility model have amplitude is good, adjustment space is big, MESH net easy to identify whether missing, rework operation letter Single, rework cost is low and the technical effect of high production efficiency.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technology neck Domain is also included in the patent protection scope of the utility model.
