[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a speaker box 100, which includes a housing 1, a sound generating unit 2, a sound outlet 3, a ventilation spacer 4 and a sealing gasket 5.
The housing 1 has a receiving space 10. Specifically, in the present embodiment, the housing includes a top wall 11 and a side wall 12 extending from the periphery of the top wall 11.
The sounding single body 2 is contained in the shell 1 and fixed with the shell 1. The sounding unit 2 comprises a diaphragm 21 for vibrating and sounding, and the diaphragm 21 and the shell 1 jointly form a front cavity 101. Specifically, the diaphragm 21 and the top wall 11 are disposed opposite to each other at a certain interval.
The sound outlet 3 is arranged through the housing 1. In this embodiment, the sound outlet hole is formed through the top wall 11 and the side wall 12. Preferably, the sound outlet 3 extends from the top wall 11 to the side wall 12. The sound outlet 3 is communicated with the front cavity 101 and used for producing sound.
This structure sets up and prevents effectively that the foreign matter from getting into in the speaker box 100 and influence the sound generating performance, simultaneously ventilative separator 4 can also adjust the damping of sound outlet 3 realizes that the high frequency improves the regulation.
In this embodiment, the housing 1 further includes a steel sheet 14 having a through hole 13. The steel sheet 14 is fixed on the top wall 11 and covers the corresponding sound outlet 3, that is, covers the sound outlet 3 on the top wall 11. The through hole 13 communicates with the sound outlet hole 3. The breathable partition 4 is positioned on one side of the steel sheet 14 far away from the front cavity 101. The steel plate 14 is arranged to improve the high-frequency sound production performance of the front cavity 101.
The sealing gasket 5 is attached to the shell 1 and arranged around the breathable separator 4.
In this embodiment, seal ring 5 laminate in the binding face of lateral wall 12 part with ventilative separator 4 laminate in the binding face of lateral wall 12 part is parallel to each other and is located the coplanar, and the binding face setting of the two is unanimous promptly, pastes when establishing the good reliability. Moreover, in correspondence of the position, the thickness of the sealing gasket 5 is greater than the thickness of the gas-permeable partition 4. Of course, the sealing gasket 5 may also have, among other things, an overall thickness greater than that of the gas-permeable partition 4.
The sealing washer 5 and the breathable isolation piece 4 are separated to form a glue applying space 20, and glue is filled in the glue applying space 20 so as to fixedly connect the breathable isolation piece 4 and the sealing washer 5 with the shell 1.
Because the thickness difference of the breathable isolating piece 4 and the sealing gasket 5 exists, after glue is applied to the glue applying space 20, the glue surface is ensured not to overflow the top surface of the sealing gasket 5, so that the loudspeaker box 100 is not influenced to be installed in a terminal, and the reliability is better. Moreover, glue filling is carried out in the glue filling space 20 so as to enable the breathable partition piece 4 and the sealing washer 5 to be fixedly connected with the shell 1, the maximum degree is extremely low, the breathable partition piece 4 and the sealing washer 5 are at a raised risk, the waterproof performance and the dustproof performance are good, and the stability and the reliability are higher.
In this embodiment, the thickness of the sealing gasket 5 is 0.3mm greater than the thickness of the air-permeable partition 4. For example, in the embodiment, the thickness of the sealing gasket is selected to be 0.4mm, and the thickness of the air-permeable separator is selected to be 0.1 mm. Of course, it is not limited to this size.
Preferably, the sealing gasket 5 comprises a first section 51 attached to the top wall 11, a second section 52 attached to the side wall 12, and a third section 53 connecting the first section 51 and the second section 52. The third section 53 is attached to the joint of the top wall 11 and the side wall 12, and the third section 53 is in a rounded structure. The structure arrangement enables the seal washer 5 to be smoothly transited when being bent from the top wall 11 to the side wall 12, the waterproof sealing performance is not affected, and the reliability of waterproof sealing is improved.
In this embodiment, the sealing washer 5 is a silica gel washer. Other materials, such as rubber, etc., are also possible.
In addition, casing 1 caves in and forms and hold gluey groove 7, hold gluey groove 7 encircle ventilative separator 4 sets up and with beat gluey space 20 intercommunication. This construction makes it possible to contain more glue during gluing, further strengthening the fixing strength between the gas-permeable barrier 4 and the sealing gasket 5 and between both and the casing 1.
Preferably, in the present embodiment, the glue storage groove 7 is disposed opposite to the glue applying space 20.
Compared with the prior art, the utility model discloses a loudspeaker box will seal ring laminating in the binding face of lateral wall portion and ventilative isolator laminating in the binding face of lateral wall portion sets up to be parallel to each other and lie in the coplanar, form unanimously, and make seal ring's thickness be greater than ventilative isolator's thickness, seal ring with ventilative isolator interval forms the space of beating glue, the space of beating glue is filled with glue in order to with ventilative isolator and seal ring all with casing fixed connection, very low the ventilative isolator and the risk that seal ring rises, waterproof and dustproof nature is good, and stability and reliability are higher; in addition, seal ring laminating in the roof with the lateral wall junction design is the fillet structure, and is too gentle, further avoids seal ring raises the risk of warping.
