[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a speaker box 100, which includes an upper cover 1, a lower cover 2 covering the upper cover 1 and forming an accommodation space 10, a sound generating unit 3 accommodated in the accommodation space 10, a supporting wall 4, a through hole 5, a sound generating cavity 6, and a sound absorbing unit 7.
The housing space 10 is divided into a front chamber 101 and a rear chamber 102 by the sound generating unit 3. The front cavity 101 is used for sound production and the back cavity 102 is used for improving low frequency acoustic performance.
The upper cover 1 includes a bottom wall 11, a sidewall 12 extending from the bottom wall 11 and having a sound outlet 120, a support wall 4 extending from the bottom wall 11 toward the lower cover 2 and abutting against the lower cover 2, and a connecting wall 13 extending from the bottom wall toward the lower cover 2 and connecting the support wall 4 and the sidewall 12. The support wall 4, the bottom wall 11 and the side wall 12 together enclose a sound-generating chamber 6. The sound outlet chamber 6 communicates with the sound outlet hole 120.
Specifically, the supporting wall 4 is provided with a step portion 41, and the step portion 41 is formed by recessing the side of the supporting wall 4 close to the lower cover 2 towards the upper cover 1.
The through-hole 5 is provided through the support wall 4. In this embodiment, the through holes 5 include at least two through holes and are spaced apart from each other. Of course, a single through hole 5 or a plurality of through holes may be provided.
In addition, the structure arrangement can facilitate the arrangement of sound absorption materials and the like in the sound outlet cavity 6 so as to improve the sound outlet performance. For example, in the present embodiment, the sound absorbing unit 7 is provided in the sound outlet chamber 6, and the sound absorbing unit 7 is preferably made of sound absorbing cotton.
The sound production monomer 3 fixed stay in support wall 4 and with 11 intervals of diapire of upper cover 1 set up and form preceding sound chamber 8, through-hole 5 will preceding sound chamber 8 with play sound chamber 6 intercommunication, make preceding sound chamber 8 with play sound chamber 6 forms jointly preceding chamber 101 for the sound production. Preferably, in the present embodiment, the sound generating unit 3 is supported and fixed to the stepped portion 41.
Because the sound production monomer 3 support in support wall 4, then through adjusting on the support wall 4 the size of through-hole 5 then can make preceding sound chamber 8 communicates with play sound chamber 6 with maximum dimension, and then makes preceding sound chamber 8 sound more unobstructed, and acoustic performance is more excellent.
The sound generating unit 3, the lower cover 2 and the upper cover 1 jointly enclose the rear cavity 102, so as to improve the low-frequency acoustic performance of the loudspeaker box.
It should be noted that, on the supporting wall 4, when the through holes 5 are provided with at least two and spaced from each other, it is equivalent to two adjacent through holes 5 are additionally provided with a blocking wall, so that the sound absorption unit 7 can be effectively prevented from entering the front sound cavity 8 to influence the normal operation of the sound generation unit 3. Of course, it is also possible to provide the through-hole 5 in one size smaller than the sound-absorbing unit 7, and this can be done for the same purpose, as well as the same principle.
In order to realize the sealed isolation of the front cavity 101 and the rear cavity 102, in this embodiment, the support wall 4, the side wall 12, and the connecting wall 13 are all provided with a welding rib 9 on one side close to the lower cover 2, and are formed to be sealed and fixed with the lower cover 2 through the welding rib 9, so that the front cavity 101 and the rear cavity 102 are sealed and isolated simultaneously.
Compared with the prior art, the loudspeaker box is provided with the support wall extending towards the lower cover from the upper cover and the sound-emitting cavity formed in the upper cover, the sound-emitting single body is supported and fixed on the support wall and forms a front sound cavity with the upper cover in an enclosing mode, and the sound-absorbing unit is arranged in the sound-emitting cavity, so that the acoustic performance of the loudspeaker box is improved; in addition, through support the wall set up the through-hole make preceding sound chamber with go out the sound chamber intercommunication, make preceding sound chamber can maximum width intercommunication go out the sound chamber, thereby make preceding sound chamber goes out the sound more unobstructed, and acoustic performance is more excellent.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
