[0023] The technical solution of this utility model will be further clearly and completely described below with reference to the accompanying drawings and through embodiments. The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components. Unless otherwise expressly limited, those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] like Figure 1-6 As shown, a multi-cavity Bluetooth speaker includes a speaker body 1 and a connecting body 2. The speaker body 1 has a first cavity 11 serving as a sound cavity, and a speaker 3 is disposed in the first cavity 11. An opening 12 is formed in the middle of the top of the first cavity 11. The connecting body 2 is embedded in the opening 12. A second cavity 21 is disposed in the connecting body 2, and a motherboard 4 is disposed in the second cavity 21. The speaker 3 and the motherboard 4 are electrically connected.

[0027] The first cavity 11 is used to install the speaker 3, so that the speaker can have an independent sound cavity. The internal space of the sound cavity is more organized. When the sound wave enters the sound cavity, it will be reflected and resonated in an orderly manner within the sound cavity, forming a resonance mode. This resonance mode can enhance the sound wave of a specific frequency, thereby improving the overall sound quality. Conversely, if multiple components are installed in the sound cavity, it is easy to make the internal structure layout of the sound cavity chaotic, forming an irregular scattering surface, causing the sound wave to scatter and producing a messy superposition effect, resulting in poor audio effect. The speaker can use an external power supply or be powered by a built-in battery 5. The second cavity 21 can be used to install components such as the motherboard 4 and the battery 5.

[0028] like Figure 4-5As shown, the speaker body 1 includes a front shell 13 and a rear shell 14 that are fixed to each other and form a first cavity 11. The connecting body 2 includes a base 22 and a top shell 23 fixed to the top of the base 22. The base 22 and the top shell 23 are fixed to each other and form a second cavity 21.

[0029] like Figure 5 As shown, the front and back of the base 22 are provided with connecting posts 221 in the horizontal direction. The opposite sides of the front shell 13 and the rear shell 14 (the back of the front shell 13 and the front of the rear shell 14) are provided with connecting seats 15 that are adapted to the connecting posts 221 in the horizontal direction. The connecting posts 221 are installed in the connecting seats 15. The cooperation between the connecting posts 221 and the connecting seats 15 can not only fix the connecting body 2 on the speaker body 1, but also make the front shell 13 and the rear shell 14 more secure.

[0030] like Figure 5 As shown, a positioning seat 222 is provided on the outer periphery of the base 22 in the vertical direction, and a positioning post 231 is provided on the outer periphery of the bottom of the top shell 23 in the vertical direction to cooperate with the positioning seat 222. The positioning post 231 is installed inside the positioning seat 222. The cooperation between the positioning post 231 and the positioning seat 222 makes the installation and positioning between the base 22 and the top shell 23 more convenient and more secure.

[0031] like Figure 3 As shown, the inner wall of the opening 12 is provided with an embedding groove 121, and the outer periphery of the middle part of the top shell 23 is provided with an outer edge 232. The outer edge 232 is embedded in the embedding groove 121. By setting the outer edge 232 and the embedding groove 121, the opening 12 can be closed so that the first cavity 11 has good airtightness and can play a certain role in waterproofing and dustproofing.

[0032] like Figure 5 As shown, a horn mounting position 131 is recessed in the center of the front of the front shell 13. A horn mounting port 132 communicating with the first cavity 11 is opened in the middle of the horn mounting position 131. One end of the horn 3 is fixed in the horn mounting position 131, and the other end passes through the horn mounting port 132 and is set in the first cavity 11.

[0033] like Figure 6 As shown, a partition 223 is provided inside the base 22, which is used to divide the interior of the base 22 into multiple installation areas 224. Different components can be installed in the installation areas 224. Installation grooves 2241 are provided in the vertical direction in the installation areas 224. The installation grooves 2241 are arranged parallel to the side walls on the left and right sides of the installation areas 224. The top of the installation grooves 2241 is provided with an opening, which can be used to insert and fix strip-shaped components such as the motherboard 4 between the installation grooves 2241.

[0034] like Figure 4 As shown, a front shell 133 is installed on the front of the front shell 13, and a back shell 141 is installed on the back of the rear shell 14. The front shell 133 and the back shell 141 are used to protect the speaker body 1 and also have a decorative effect.

[0035] like Figure 4 As shown, the speaker body 1 is also provided with a third cavity. The third cavity includes a groove 16 provided on the back of the rear shell 14. The third cavity is formed by the back shell 141 and the groove 16, and can also be used to install components such as the motherboard 4 and the battery 5.

[0036] like Figure 3-4 As shown, the speaker body 1 also has diaphragm mounting ports 17 on the left and right sides that are connected to the first cavity 11, and a diaphragm 171 is installed in the diaphragm mounting port 17.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
