At present, in order to ensure sound quality, a micro-speaker located inside an electronic device is usually provided with a suitable cavity in front of and behind a vibration unit of the speaker, so as to form a front sound cavity and a rear sound cavity which are separated from each other. The front sound cavity can help to correct high-frequency noise, and improve the effects of middle and high frequencies and the like. The rear sound cavity can make the low-frequency sound more powerful, and avoid the short circuit of middle and low frequency sound. In practical design processes, it is always desirable to have a larger volume in the rear sound chamber to enhance the sound quality of the speaker, especially in the low frequency part

The applicant has noted that the conventional placement of the sound guide tube and its associated fixation structure fixed to the rear sound chamber occupies a portion of the volume of the sound chamber, which negatively affects the bass effect. Therefore, through proper structural design, the accommodating and fixing mode of the sound guide tube is changed to avoid the sound guide tube occupying the rear sound cavity, so that the volume utilization efficiency and the listening experience of the loudspeaker are improved.

For a full description of the present application, the following detailed description will be given with reference to specific examples of speaker assemblies, where the foregoing specific implementation of avoiding occupation of the rear sound cavity by the sound guide tube is described. Fig. 1 is a schematic structural diagram of a speaker assembly according to an embodiment of the present application.

Referring to fig. 1, the speaker assembly may include: the bracket 100, the sound unit 200, and the sound guide tube.

The bracket 100 is a foundation structure for supporting and fixing, and has a receiving space formed therein. The bracket 100 may be made of any suitable material, size or shape according to the actual situation. In this embodiment, the sound guide groove 300 is formed on the solid structure of the bracket 100.

The sound generating unit 200 is a transducer element for performing electroacoustic conversion, and is capable of driving a diaphragm or the like to vibrate correspondingly based on the received electrical signal to generate a corresponding sound. The specific implementation thereof is well known to those skilled in the art and will not be described in detail herein. In the present embodiment, the sound emitting unit 200 is fixed inside the holder 100. Part of the receiving space of the holder 100 forms a rear sound chamber.

A sound guide tube (not shown) is a structure for communicating the rear sound chamber with the external space. Which may help sound to pass out of the back of the speaker. In this embodiment, the sound guiding groove 300 may have a size adapted to the sound guiding tube, so that the sound guiding tube may be conveniently accommodated and fixed in the sound guiding groove 300.

The loudspeaker assembly provided by the embodiment of the application can enable the sound guide tube to be buried in the support through the sound guide groove formed in the support, and not protrude out of the support. The accommodating and fixing structure can prevent the sound guide tube from occupying the rear sound cavity. On the premise of occupying the same volume of the loudspeaker assembly, the volume of the rear sound cavity can be effectively improved relative to the structural design of placing the sound guide tube in the rear sound cavity. In addition, the structural design mode embedded in the bracket is also beneficial to fixing the sound guide tube, so that the reliability allowance of the product can be improved.

The second end opening 320 is formed in the bottom wall of the bracket and is an opening communicating with the rear sound cavity. The connection portion 330 is a portion connected between the first end opening 310 and the second end opening 320, and may be designed to have a size adapted to the sound guide tube so that the sound guide tube can be buried therein.

It should be noted that the terms "first" and "second" are used herein for ease of description to modify the two end openings. The "first" and "second" are used only for distinguishing descriptions and are not used for specifically limiting the shape, size, etc. of the opening to be modified.

Specifically, as shown in fig. 2, the connection portion 330 may be a groove having a predetermined depth. The top end opening of the groove extends to the edge of the bottom wall of the bracket at one end to form a first end opening parallel to the height direction. And the other end of the groove is connected to a second end opening formed in the bottom wall of the bracket through a connection slope 340 having a predetermined inclination angle.

Based on the functional principle of the above-mentioned sound guide groove 300, those skilled in the art can choose to use other similar structures according to the needs of practical situations, and only needs to meet the needs of practical use, so as to realize the accommodating and fixing of the sound guide tube.

For example, the recess may be generally L-shaped, including a first connection portion and a second connection portion extending in mutually perpendicular directions.
