[ 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 to 3, the present invention provides a speaker box 100, where the speaker box 100 includes an upper shell 1, a lower shell 2 and a speaker unit 3, the upper shell 1 and the lower shell 2 cooperate to form an accommodating space, the speaker unit 3 is accommodated in the accommodating space, the speaker unit 3 includes a vibrating diaphragm 31, and the vibrating diaphragm 31 and the upper shell 1 are arranged at an interval to form a front acoustic cavity 4. The loudspeaker enclosure 100 further comprises a sound outlet channel 5 formed in the upper housing 1 and communicating the front sound cavity 4 with the outside.

The upper shell 1 is used for bearing and protecting the speaker unit 3, and includes a top wall 11 disposed opposite to the diaphragm 31 at an interval, a side wall 12 extending from a periphery of the top wall 11 to a direction close to the diaphragm 31, and an extension wall 13 extending from the side wall 12 to a direction away from the diaphragm 31, where the extension wall 13 is disposed at an interval from the top wall 11, and the speaker unit 3 is borne on the extension wall 13. The sound outlet channel 5 is enclosed by an extension wall 13 cooperating with the top wall 11 and the side wall 12.

The lower shell 2 is covered on the side wall 12 and matched with the upper shell 1 to form the accommodating space, and the loudspeaker monomer 3 is clamped between the lower shell 2 and the upper shell 1. The diaphragm 31 is used for vibrating and sounding. The front acoustic cavity 4 and the sound outlet channel 5 together form a front cavity of the loudspeaker box 100, and the diaphragm 31 cooperates with the upper shell 1 and the lower shell 2 to form a rear cavity 6.

One of the upper shell 1 and the lower shell 2 is provided with a protrusion 10, the other one is provided with a groove 20 matched with the protrusion 10, the protrusion 10 is correspondingly accommodated in the groove 20, a gap 30 is formed between the protrusion 10 and the groove wall of the groove 20 at an interval, and glue is contained in the gap 30. It will be appreciated that the gap 30 is part of the recess 20.

Specifically, in the present embodiment, the protrusion 10 is formed in the lower case 2 protruding toward the upper case 1, and the groove 20 is formed in the upper case 1 recessed toward the direction away from the lower case 2. In other embodiments, the protrusion 10 may be further disposed on the lower case 2, and the groove 20 may be further disposed on the upper case 1, which is not limited in the present invention. Further, the protrusion 10 and the lower case 2 are integrally formed, and the structure is stable.

Inferior valve 2 including being close to the first upper surface 21 of epitheca 1 and with the lower surface 22 that first upper surface 21 set up relatively, protruding 10 include with first upper surface 21 parallel arrangement's second upper surface 101, inferior valve 2 still includes certainly lower surface 22 straight line extends to some glue holes 40 of second upper surface 101, some glue holes 40 with clearance 30 intercommunication, glue by some glue holes 40 pour into, get into clearance 30. The number of the glue dispensing holes 40 is multiple, and the glue dispensing holes 40 are distributed at equal intervals, so that uniform glue dispensing at all positions can be realized.

Referring to fig. 4(a) and 4(b), the whole of the groove 20 is rectangular ring-shaped, the whole of the protrusion 10 is also rectangular ring-shaped, and the protrusion 10 is disposed corresponding to the position of the groove 20.

The groove 20 includes a first groove 210 and a second groove 220 communicated with the first groove 210, wherein the first groove 210 is disposed near the lower case 2, a central axis of the first groove 210 and a central axis of the second groove 220 are located on the same straight line, and an opening of the first groove 210 is larger than an opening of the second groove 220.

The connection process of the upper shell 1 and the lower shell 2 is as follows: abutting the lower shell 1 and the lower shell 2 until the protrusion 10 is correspondingly accommodated in the groove 20, specifically, the protrusion 10 is accommodated in the second groove 220 and forms the gap 30 with the groove wall of the groove 20 at an interval, injecting excessive glue into the groove 20 through the glue dispensing hole 40, and the glue is diffused along the gap 30 and is firmly connected; the first groove 210 is communicated with the gap 30, redundant glue enters the first groove 210, and after the glue is cooled, the protrusion 10 is fixedly connected with the upper shell 1. It can be understood that the connection surfaces of the protrusions 10 and the upper shell 1 are five planes, which greatly increases the connection firmness of the upper shell 1 and the lower shell 2, can resist the force action in the tangential direction and the stretching direction at the same time, and is safe and reliable to use.

Furthermore, the glue dispensing hole 40 is directly exposed on the outer surface of the lower shell 2, so that glue can be directly dispensed by a glue dispenser, industrial mass production is easy to realize, and meanwhile, the glue dispensing amount of the same batch of products can be fixed by calculating the size of the gap to which the glue dispensing hole belongs, and waste is avoided.

Furthermore, glue in the gap 30 is cooled to form an annular sealing structure and is distributed on the inner side and the outer side of the protrusion 10, so that the sealing performance of the connection between the upper shell 1 and the lower shell 2 is greatly improved, and the waterproof performance is improved.

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.
