[ 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. 1-6, the speaker box 100 according to the present invention includes a housing 11 having an accommodating space, a sound generating unit 12 accommodated in the accommodating space of the housing 11, a ventilation spacer 13, a sealing member 14, and sound absorbing particles 15. The housing 11 includes an upper cover 111 and a lower cover 112, the upper cover 111 and the lower cover 112 are assembled to form the accommodating space, and the sound generating unit 12 is fixed to the upper cover 111 and divides the accommodating space into a front cavity and a rear cavity 113 opposite to the front cavity.

The upper cover 111 comprises a top wall 1111, a side wall 1112 extending from the top wall 1111 along the edge in a bending manner, and a mounting groove 1113 arranged on the top wall 1111, wherein the sounding single body 12 is mounted in the mounting groove 1113 and is opposite to the top wall 1111 and arranged at intervals. The side wall 1112 is abutted against and fixed to the lower cover 112, thereby forming the receiving space. The top wall 1111 is provided with a first through hole 1114, a sealing groove 1115, a second through hole 1116 penetrating the sealing groove 1115, and a blocking portion 1117, the sealing groove 1115 is disposed on the side of the top wall 1111 far away from the rear cavity 113, the blocking portion 1117 is disposed on the side of the top wall 1111 near the rear cavity 113, and the first through hole 1114 and the second through hole 1116 are both communicated with the rear cavity 113. The sound-absorbing particles 15 are filled in the rear cavity 113 through the second through-holes 1116, the sound-generating unit 12 leaks out of the speaker box 100 through the first through-holes 1114, and the air-permeable partition 13 is mounted on the barrier 1117 to separate the sound-absorbing particles 15 from the first through-holes 1114 by the barrier 1117; the seal 14 is mounted in the seal groove 1115 to close the second through-hole 1116. The air-permeable partition 13 is made of an air-permeable material, so that the rear cavity 113 can leak out of the speaker box 100 through the first through hole 1114, and optionally, the air-permeable partition 13 is any one of damping cloth, non-woven cloth, dust-free mesh cloth, nylon woven mesh, or metal mesh.

Wherein the blocking part 1117 and the air-permeable partition 13 are used to block the sound-absorbing particles 15 from blocking the first through-holes 1114. Specifically, the stopper 1117 protrudes upwardly from the top wall 1111 and extends toward the rear chamber 113, the stopper 1117 and the top wall 1111 form an air-permeable space 1118 communicating with the first through hole 1114, the stopper 1117 has an opening 11171, and the air-permeable partition 13 is mounted to the stopper 1117 and closes the opening 11171. Since the air-permeable partition 13 has air permeability, so that the opening 11171 connects the air-permeable space 1118 and the rear cavity 113 together in an air-permeable manner, the rear cavity 113 is in air-permeable communication with the first through hole 1114 through the opening 11171 and the air-permeable space 1118. The air-permeable space 1118 formed by the barrier 1117 and the top wall 1111 not only increases the leakage space of the rear chamber 113 but also prevents the leakage of the rear chamber 113 due to the blocking of the first through holes 1114 by the sound-absorbing particles 15.

In this embodiment, preferably, the stopper 1117 is an annular wall protruding from the top wall 1111, and the stopper 1117 has a cylindrical or square column shape and surrounds the first through hole 1114 and forms the air-permeable space 1118 with the top wall 1111. The opening 11171 is disposed at an end of the stopper 1117 away from the first through hole 1114. Optionally, the stop 1117 is cylindrical.

In other embodiments, the stopper 1117 may be a cover protruding from the top wall 1111 and covering the first through hole 1114, and the opening 11171 may be formed on a sidewall of the stopper 1117.

As shown in fig. 1 and 6, the air-permeable partition 13 is provided with a third recess 131, the third recess 131 faces the air-permeable space 1118 and is aligned with the first through hole 1114, and a space in the third recess 131 is communicated with the air-permeable space 1118, so that the volume of the air-permeable space 1118 is increased, and thus the leakage space of the rear cavity 113 is increased. In addition, the third groove 131 corresponds to the first through hole 1114, so that the breathable separator 13 becomes thinner at a portion corresponding to the first through hole 1114, further increasing the breathability of the breathable separator 13.

The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
