[0032] This utility model proposes a small speaker.
[0033] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the small speaker includes a housing 10, a speaker 20, and a circuit assembly 30.
[0034] The housing 10 has a first mounting cavity 13 and a second mounting cavity 14, which are separated by a partition. The housing 10 is provided with a sound outlet 17, which communicates with the first mounting cavity 13. The cavity wall of the first mounting cavity 13 is provided with a first slot 131, and the two opposite side walls of the second mounting cavity 14 are provided with limiting grooves 141. The speaker 20 is disposed in the first mounting cavity 13 and is inserted into the first slot 131, with the sound outlet side of the speaker 20 facing the sound outlet 17. The circuit assembly 30 is disposed in the second mounting cavity 14 and is installed between the two limiting grooves 141. The circuit assembly 30 is electrically connected to the speaker 20.
[0035] Specifically, the interior of the housing 10 is divided into two independent cavities by a partition: a first mounting cavity 13 and a second mounting cavity 14. The first mounting cavity 13 communicates with the sound outlet 17 of the housing 10. The speaker 20 is installed in the first mounting cavity 13 and fixed by a first slot 131. The sound outlet side of the speaker 20 faces the sound outlet 17 of the housing 10 to ensure effective sound transmission. The speaker 20 is connected to the circuit assembly 30 via wires, receiving audio signals and emitting sound. The circuit assembly 30 is installed in the second mounting cavity 14 and fixed by limiting slots 141 on both sides. The circuit assembly 30 is electrically connected to the speaker 20 and is responsible for processing audio signals and driving the speaker 20 to operate.
[0036] By setting the first slot 131 to install and fix the speaker 20, and setting the limiting slot 141 to install the circuit assembly 30, the speaker 20 and the circuit assembly 30 do not need to be tightened when installing or removing them. This makes the assembly and maintenance of the speaker 20 and the circuit assembly 30 more convenient, thereby improving the efficiency of the speaker 20 and the circuit assembly 30.
[0037] Furthermore, by dividing the interior of the housing 10 into a first mounting cavity 13 and a second mounting cavity 14 by a partition, acoustic isolation can be achieved, avoiding interference from the circuit components 30 to the speaker 20, which is beneficial to improving the sound quality of the small speaker.
[0038] This utility model's technical solution involves providing a first mounting cavity 13 and a second mounting cavity 14 within a housing 10, separated by a partition. The housing 10 has a sound outlet 17 communicating with the first mounting cavity 13. A first slot 131 is provided on the cavity wall of the first mounting cavity 13, and limiting grooves 141 are provided on the two opposite side walls of the second mounting cavity 14. A speaker 20 is placed in the first mounting cavity 13 and inserted into the first slot 131, with the sound outlet side of the speaker 20 facing the sound outlet 17. A circuit assembly 30 is placed in the second mounting cavity 14 and installed between the two limiting grooves 141, electrically connected to the speaker 20. This design uses the first slot 131 to mount and fix the speaker 20, and the limiting grooves 141 to mount the circuit assembly 30. This eliminates the need for screws during installation and removal of the speaker 20 and circuit assembly 30, making assembly and maintenance of the speaker 20 and circuit assembly 30 more convenient and improving the efficiency of disassembly and assembly of the small speaker enclosure.
[0039] In some embodiments, each of the two opposite sidewalls of the second mounting cavity 14 is provided with two protruding ribs 142, both of which extend along the length direction of the housing 10 and are spaced apart to form a limiting groove 141. Specifically, during installation, the circuit assembly 30 can slide into the limiting groove 141 along its length direction, making installation more convenient. Furthermore, the protruding ribs 142 eliminate the need to create grooves in the cavity wall of the second mounting cavity 14 and enhance the overall strength of the housing 10, thereby improving the stability and reliability of the overall structure. In other embodiments, the sidewalls of the second mounting cavity 14 are not provided with protruding ribs 142.
[0040] In some embodiments, the side wall of the first mounting cavity 13 is provided with a second slot 132, the small speaker also includes a rechargeable battery 70, the rechargeable battery 70 is inserted into the second slot 132, the circuit assembly 30 is provided with a charging interface 31, and the charging interface 31 and the speaker 20 are both electrically connected to the rechargeable battery 70.
[0041] Specifically, the rechargeable battery 70 is fixed in the second slot 132 via a plug-in connection, making installation simple and secure. The circuit assembly 30 has a charging interface 31 for connecting to an external power source to charge the rechargeable battery 70. The rechargeable battery 70 is connected to the circuit assembly 30 via a wire, supplying power to the circuit assembly 30. The rechargeable battery 70 is also connected to the speaker 20, providing power to ensure the speaker 20 functions properly. The design of the rechargeable battery 70 not only provides power support but also enables convenient charging through the charging interface 31, further enhancing the user experience. The type of charging interface 31 can be, but is not limited to, USB-C, USB-B, Lightning, etc., depending on the specific requirements. Furthermore, in other embodiments, the small speaker does not include a rechargeable battery 70.
[0042] In some embodiments, the miniature speaker further includes a protective sleeve 40, which wraps around the periphery of the housing 10. The protective sleeve 40 wraps around the periphery of the housing 10 (i.e., around its circumference) to prevent drops, scratches, and wear, thus extending the speaker's lifespan. Optionally, the protective sleeve 40 is made of silicone, TPU, or rubber. Furthermore, in other embodiments, the miniature speaker does not have a protective sleeve 40.
[0043] Furthermore, the protective cover 40 is detachably wrapped around the perimeter of the housing 10. This facilitates installation, removal, and cleaning for the user. Additionally, different colored protective covers 40 can be replaced according to individual preferences to enhance the user experience.
[0044] In some embodiments, the bottom of the housing 10 is also provided with a mounting port, which is connected to the first mounting cavity 13. The mounting port is disposed opposite to the sound outlet 17. The small speaker also includes a diaphragm 60, which is mounted on the mounting port.
[0045] Specifically, the mounting port is positioned opposite to the sound outlet 17 on the housing 10 to form a sound wave transmission channel. The mounting port is used to mount the diaphragm 60. The diaphragm 60 can transmit sound waves through vibration, enhancing the low-frequency response and sound field effect of the speaker. In addition, the diaphragm 60 transmits the sound waves from the back of the speaker 20 to the outside through vibration, preventing the sound waves from being canceled out inside the cabinet, thereby enhancing the low-frequency effect and expanding the propagation range of the sound waves, making the sound more three-dimensional and full.
[0046] Furthermore, a counterweight 61 is provided on the diaphragm 60. Specifically, the counterweight 61 is located in the middle of the diaphragm 60. The counterweight 61 can increase the weight of the diaphragm 60, which can adjust the vibration frequency of the diaphragm 60 to better adapt to the transmission of low-frequency sound waves. The counterweight 61 can make the vibration of the diaphragm 60 more stable and powerful in the low-frequency range, thereby improving the transmission efficiency of low-frequency sound waves. It can also suppress the vibration of the diaphragm 60 in the high-frequency range, reduce high-frequency interference, make the sound purer, and help balance the sound pressure in front and behind the diaphragm 60, reduce the sound wave cancellation phenomenon, and improve the overall sound quality.
[0047] In some embodiments, the bottom of the housing 10 is provided with a notch 15, and the notch 15 extends to the position of the diaphragm 60.
[0048] Specifically, the notch 15 is located at the bottom of the housing 10 and extends to the position of the diaphragm 60, allowing the diaphragm 60 to be directly connected to the external environment. The notch 15 serves as a channel for sound wave transmission, allowing the sound waves generated when the diaphragm 60 vibrates to be transmitted from the inside of the housing 10 to the outside, preventing the sound waves from being canceled out inside the housing 10, thereby enhancing the low-frequency effect. Furthermore, in other embodiments, the notch 15 is not provided at the bottom of the housing 10.
[0049] In some embodiments, the housing 10 includes a base 11 and an outer shell 12. The outer shell 12 has a first mounting cavity 13 and a second mounting cavity 14. The first mounting cavity 13 and the second mounting cavity 14 form an opening at the bottom of the outer shell 12, and the base 11 covers the opening. Specifically, by dividing the housing 10 into two parts, the outer shell 12 and the base 11, and providing an opening at the bottom of the outer shell 12, the installation of the speaker 20 and the circuit assembly 30 is made more convenient. Optionally, the base 11 is tightly connected to the outer shell 12 by a snap-fit, screw, or other fixing method to ensure the stability of the overall structure.
[0050] In some embodiments, the bottom surface of the housing 10 is provided with an anti-slip pad 50. The anti-slip pad 50 is used to increase friction with the tabletop to improve the placement stability of the small speaker. In other embodiments, the bottom surface of the housing 10 is not provided with an anti-slip pad 50.
[0051] In some embodiments, the outer wall of the housing 10 is provided with a lanyard hole 16. Users can attach a lanyard hole 16 to hang the small speaker during daily use, which improves the user experience.
[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
