Description

A speaker that facilitates heat dissipation Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and specifically to a loudspeaker that facilitates heat dissipation. Background Technology

[0002] A loudspeaker, also known as a "horn," is a common energy conversion device that transforms electrical signals into sound signals. The function of a loudspeaker is to make sound travel farther and louder. When a loudspeaker is working, the sound signal is converted into an electrical signal, which is then amplified by a power amplifier and converted back into a sound signal for playback.

[0003] As users' demands for audio quality continue to increase and the integration of devices becomes more sophisticated, loudspeakers need to achieve higher power output and better sound quality within a limited space. This causes a sharp increase in the heat generated by loudspeakers during operation, thus requiring heat dissipation to prevent them from being in a high-temperature environment for extended periods. This can cause changes in the resistance of the voice coil, affecting electroacoustic conversion efficiency and causing sound distortion. Furthermore, high temperatures can accelerate the aging of components such as the diaphragm and coil, shortening the lifespan of the loudspeaker. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] This embodiment of a heat-dissipating speaker, as shown in Figures 1 to 5, includes a housing 1 and a speaker body 3. The housing 1 has a through mounting hole 101, and the speaker body 3 is fixedly installed in the mounting hole 101 by bolts, with a portion of the speaker body 3 placed inside the housing 1. A heat dissipation assembly 4 is also provided inside the housing 1 to dissipate heat from the speaker body 3, thereby preventing damage to the speaker body 3 due to excessive temperature during operation.

[0025] Furthermore, the enclosure 1 includes a detachably connected cover plate 10 and a housing 11, wherein a mounting hole 101 is formed on the cover plate 10. The housing 11 includes a back plate 110 and side plates 111 surrounding the back plate 110. The back plate 110 and the side plates 111 enclose an open receiving chamber, and the heat dissipation assembly 4 is disposed in the receiving chamber.

[0026] The cover plate 10 is sealed to the opening of the housing 11. The cover plate 10 can completely cover the front opening of the accommodating chamber, so that the accommodating chamber forms a sealed space. This sealed structure can effectively prevent sound wave leakage and airflow interference, while isolating external dust from entering the accommodating chamber, ensuring the working stability of the speaker body 3 and the heat dissipation component 4.

[0027] Furthermore, the cover plate 10 is also provided with two bass reflex ports 102, which are located below the mounting holes 101 and are symmetrically arranged with respect to the mounting holes 101. Each bass reflex port 102 is also connected to a bass reflex tube 103, and the two bass reflex tubes 103 are located inside the cover plate 10 and extend into the accommodating chamber. This design allows the bass reflex tube 103 to interact with the air inside the enclosure 1, so that the sound waves radiated backward by the speaker diaphragm are phase-adjusted and radiated out from the bass reflex port 102, thereby enhancing the low-frequency response performance of the speaker with the sound waves radiated forward by the diaphragm. At the same time, the design of the bass reflex tube 103 extending into the accommodating chamber forms a directional airflow channel, which can also accelerate the exhaust of hot air inside the enclosure 1.

[0028] Furthermore, the outer surface of the cover plate 10 is also provided with a speaker mesh 2 that can cover the entire outer surface of the cover plate 10. The speaker mesh 2 is detachably connected to the cover plate 10. Specifically, the outer surface of the cover plate 10 is provided with multiple insertion rods 104, and the speaker mesh 2 is provided with insertion holes corresponding to the insertion rods 104. The speaker mesh 2 is inserted and pulled into the insertion rods 104 on the cover plate 10 through the insertion holes. By setting the speaker mesh 2, the speaker mesh 2 can prevent external dust from entering the enclosure 1 through the bass reflex port 102, ensuring the speaker body 3. Since the speaker mesh 2 is detachably connected to the cover plate 10, when there is too much dust on the speaker mesh 2, the speaker mesh 2 can be directly removed for easier dust removal.

[0029] Furthermore, a connector 6 is also provided inside the housing 11. The connector 6 is fixedly installed on the back plate 110. The back plate 110 is provided with a mounting port 1101 for installing the connector 6. The interface of the connector 6 inside the housing 11 is electrically connected to the speaker body 3 through a wire, while the interface of the connector 6 outside the housing 11 is used to connect to an external power source to supply power to the speaker body 3.

[0030] Furthermore, the heat dissipation assembly 4 includes a radiator 40, pipes, and a water-cooled box 43. The radiator 40 is installed close to the heat-generating part of the speaker body 3 within the accommodating cavity. The radiator 40 and the water-cooled box 43 are connected by pipes, which include an inlet pipe 41 and an outlet pipe 42. The radiator 40 is provided with a first inlet 401 and a first outlet 402. The water-cooled box 43 is provided with a second inlet 431 and a second outlet 432. The two ends of the inlet pipe 41 are respectively connected to the second outlet 432 of the water-cooled box 43 and the first inlet 401 of the radiator 40. The two ends of the outlet pipe 42 are respectively connected to the first outlet 402 of the radiator 40 and the second inlet 431 of the water-cooled box 43. Its working principle is as follows: the coolant flows out from the first outlet 402 of the radiator 40, enters the second inlet 431 of the water-cooled tank 43 through the outlet pipe 42, and after being cooled in the water-cooled tank 43, it flows out from the second outlet 432 and is transported to the first inlet 401 of the radiator 40 through the inlet pipe 41, thereby forming a circulating cooling system.

[0031] During this cycle, the coolant absorbs the heat generated by the speaker body 3 as it flows through the radiator 40, and then enters the water cooling box 43 for cooling. After the temperature is reduced, it flows back to the radiator 40 to achieve continuous and effective heat dissipation.

[0032] The water-cooled box 43 is fixedly installed on the back plate 110 or any side plate 111, while the radiator 40 is tightly attached to the speaker body 3 by bolts. Specifically, the speaker body 3 is partially placed inside the cabinet 1 and has a first mounting plate 30 extending from it. The radiator 40 has a second mounting plate 403 corresponding to the first mounting plate 30 extending from it. The first mounting plate 30 and the second mounting plate 403 are fixed together by bolts.

[0033] Furthermore, a support member 5 is also provided inside the housing 11. The support member 5 is used to support the heat sink 40, preventing the heat sink 40 on the speaker body 3 from loosening or even falling off due to prolonged vibration during operation. The support member 5 includes a support frame 50, which is fixedly installed inside the housing 11, and its two outer side walls are fixedly installed on the inner side walls of the left and right side plates 111. The support member 5 also includes a support plate 51, which is fixed inside the support frame 50. The support plate 51 has a through hole 510 in the middle for the heat sink 40 to pass through, and the inner wall of the through hole 510 is tightly fitted to the outer surface of the heat sink 40. When the heat sink 40 is connected to the speaker body 3 by bolts, the bolts simultaneously pass through the support plate 51, further strengthening the fixation between the heat sink 40 and the support member 5.

[0034] Among them, the support plate 51 is an elastic rubber plate. With this design, the elasticity of the rubber can absorb the vibration energy of the speaker and reduce the mechanical impact transmitted to the radiator 40. At the same time, through deformation, the inner wall of the through hole 510 is always tightly attached to the outer surface of the radiator 40, which not only stabilizes the radiator 40 but also avoids rigid friction damage.

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
