[0002] As living standards continue to improve, people are turning to music to de-stress and relax, both in their daily lives and after work. Bluetooth speakers are becoming increasingly common. However, the size of a Bluetooth speaker's internal cavity significantly impacts sound quality. Most existing Bluetooth speakers cannot adjust the volume of their internal cavity. Furthermore, the small internal cavity of a Bluetooth speaker weakens the amplitude of the subwoofer, preventing the sound from radiating outward and resulting in a low volume. Furthermore, the small internal cavity of a Bluetooth speaker prevents the woofer from vibrating too loudly, weakening the bass. Utility Model Content

[0028] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0030] like Figure 1 and Figure 2 As shown, the present invention provides an adjustable volume speaker structure, comprising a sound-generating part 1 and a base 2 , wherein the sound-generating part 1 is movably sleeved in the base 2 .

[0031] Specifically, if Figure 3 and Figure 4 As shown, the sound-generating unit 1 includes a first mounting portion 11, a bass reflex tube 12, multiple sliding rods 13, and a speaker 14. A first mounting hole 111 and a second mounting hole 112 are defined on the top of the first mounting portion 11. The speaker 14 is disposed within the first mounting hole 111. One end of the bass reflex tube 12 is disposed within the second mounting hole 112, and the other end is disposed within the first mounting portion 11. The bass reflex tube 12 connects the top of the first mounting portion 11 with the interior of the first mounting portion 11. Multiple sliding rods 13 are disposed within the first mounting portion 11, and multiple latching holes 113 are also disposed on the side surfaces of the first mounting portion 11. The speaker 14 is used to generate and radiate sound outward, while the bass reflex tube 12 is used to expand the sound within the speaker enclosure. The sound resonates within the tube channel of the bass reflex tube 12, enhancing the bass effect.

[0032] Specifically, if Figure 5 As shown, the base 2 includes a second mounting portion 21 and multiple sliding sleeves 22. The multiple sliding sleeves 22 are disposed within the second housing 21. When the first mounting portion 11 and the second mounting portion 22 are relatively connected, one end of the first mounting portion 11 is inserted into the second mounting portion 21, and each sliding rod 13 is correspondingly inserted into each sliding sleeve 22. Each sliding rod 13 is slidably connected to each sliding sleeve 22. Each sliding sleeve 22 is also provided with an elastic member 221. One end of the elastic member 221 is elastically connected to the sliding sleeve 22, and the other end of the elastic member 221 is elastically connected to the sliding rod 13. Multiple limiting members 23 are also provided on the side of the second mounting portion 21. In this example, the elastic member 221 is a spring.

[0033] The limiting member 23 and the locking hole 113 are engaged with each other. Figure 1 and Figure 2 As shown, since the speaker is in a non-working state, the elastic member 221 is squeezed and stores elastic potential energy. When the adjustable volume speaker structure is working, the limit member 23 is opened, so that the limit member 23 is disengaged from the card hole 16, and the elastic member 221 lifts the slide rod 13 under the action of the elastic potential energy, and the slide rod 13 drives the first mounting part 11 to lift. When the elastic potential energy of the elastic member 221 is zero, the first mounting part 11 is lifted to the highest point, and the elastic member 221 supports the first mounting part 11 to prevent the first mounting part 11 from falling, thereby expanding the volume of the speaker structure.

[0034] When the speaker is not in use, Figure 2 As shown, the first mounting portion 11 is received in the second mounting portion 21. Due to the action of the elastic member 221, the limiting member 22 and the card hole 18 need to be used to cooperate and fix the first mounting portion 11 to prevent the elastic member 221 from lifting the slide rod 17 to avoid the first mounting portion 11 being lifted.

[0035] In this example, three sliding rods 13 and three sliding sleeves 22 are respectively provided, and two locking holes 113 and two limiting members 22 are respectively provided.

[0036] Furthermore, if Figure 4 As shown, a mounting slot 114 is further provided in the first mounting portion 11, and a control unit 1141 is provided in the mounting slot 114. The control unit 1141 is electrically connected to the speaker 14. The control unit is used to control the speaker 14, such as the volume and other functions of the speaker 14.

[0037] Furthermore, if Figure 5 As shown, the second mounting portion 21 further includes a placement slot 211, which houses a power supply 2111. Power supply 2111 is electrically connected to the control unit 1141 and the speaker 14. Power supply 2111 provides power to the control unit 1141 and the speaker 14, and the control unit 1141 controls power supply 2111 to prevent overcharging. In this example, power supply 2111 is a lithium battery.

[0038] Furthermore, if Figure 1 and Figure 6 As shown, the first mounting portion 11 is further provided with a charging port 115, and the control portion 1141 is further provided with a charging terminal 11411. The charging terminal 11411 is sleeved on the charging port 115 and electrically connected to the power supply 2111. During charging, an external power source is connected to the charging terminal 11411 through the charging port 115, and the power supply 2111 is charged through the charging terminal 11411.

[0039] Furthermore, if Figure 1 As shown, a dust cover 15 is also provided on the top of the first sound-emitting part 1, and the dust cover 15 is snapped onto the top of the sound-emitting part 1. The dust cover 15 prevents external pollutants from entering the interior of the sound structure through the inverted tube 12, thereby preventing damage to the internal components of the sound structure.

[0040] Preferably, if Figure 6 As shown, one end of the inverted tube 12 disposed in the first mounting portion 11 is wound around the periphery of the speaker 14. In this way, the inverted tube 12 can reduce the space occupied by the speaker structure.

[0041] Preferably, if Figure 2 As shown, a pull ring 24 is also provided on the base 2. By arranging the pull ring 24, people can conveniently grab or move the speaker when in use.

[0042] In summary, the present invention increases the sound volume of speaker 14 by using the inverted tube 12, while also enhancing the bass intensity of speaker 141. Furthermore, by providing a slide rod 13 within the first mounting portion 11 and a sleeve 22 corresponding to the slide rod 13 within the second mounting portion 21, the volume of the speaker structure is increased, thereby better expanding the sound of speaker 14, thereby increasing the volume and further enhancing the bass intensity.

[0043] The above is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
