[0002] Subwoofer speakers, because they emit the longest sound waves, process the sound signals through the circuit, so that the listener feels that the sound image extends to the outside of the two speakers, so as to expand the sound image, give people a sense of space and three-dimensionality, and produce a wider stereo effect, which can make the restoration of program sources more cheerful and enthusiastic, giving people a warm and passionate feeling. Since subwoofer speakers have many components and compact structure, long-term use will cause a lot of heat accumulation, which affects the use experience and also reduces the service life of the speakers.

[0003] After searching, the application number CN202321918792.1 discloses a speaker with a heat dissipation structure, including a speaker body, a mesh cover is fixedly and insertedly connected to the middle of the front end of the speaker body, a loudspeaker is fixedly and insertedly connected to the middle of the front end of the mesh cover, a positioning device is movably connected to the upper left and right ends of the speaker body, a dustproof net is inserted at the rear of the left end of the speaker body, a heat absorption structure is installed in the middle of the upper box wall and the middle of the lower box wall of the speaker body, and a heat dissipation structure is installed at the rear of the upper inner wall of the speaker body, which can dissipate heat from the equipment and extend its service life.

[0004] The existing heat dissipation structure can only absorb and dissipate heat on one side of the speaker body, which limits the heat dissipation efficiency to a certain extent. At the same time, when the speaker body is working, vibration will be generated. The vibration is transmitted from the connection to the external shell, causing resonance, which reduces the sound quality to a certain extent and affects the user experience. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional subwoofer speaker with efficient heat dissipation to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a multifunctional subwoofer speaker with efficient heat dissipation, comprising a speaker body, a shell is installed on the rear end outer wall of the speaker body, the speaker body comprises a loudspeaker, a mounting plate is fixedly connected to the front end outer wall of the loudspeaker, a plurality of groups of heat absorbing teeth are fixedly connected to the rear end outer wall of the loudspeaker at intervals, the shell comprises a heat dissipation sleeve, a plurality of groups of heat dissipation fins are fixedly connected to the inner wall of the heat dissipation sleeve at intervals, and the heat dissipation fins are staggered with the heat dissipation teeth.

[0007] As a further preference, the heat dissipation sleeve includes a connecting sleeve, an air outlet screen is provided on the outer wall of the connecting sleeve near the front end, an air inlet grille is fixedly connected to the rear end of the connecting sleeve, and a heat dissipation fan is installed on one side of the connecting sleeve inner cavity near the air inlet grille.

[0013] The utility model provides a shell, and when installed, the heat absorbing teeth on the outer wall of the loudspeaker move along the heat dissipation fins toward the inner cavity of the connecting sleeve. When the heat absorbing teeth move, they are inserted into the limiting grooves and push the clamping plate along the guide slope to compress the elastic component and move it along the heat dissipation fins toward the inner wall of the connecting sleeve. The heat absorbing teeth cooperate with the limiting grooves to make the clamping plate movable and always remain parallel to the heat dissipation fins. At the same time, the deformed elastic component pushes the clamping plate to move in a direction away from the inner wall of the connecting sleeve, thereby clamping the heat absorbing teeth and fixing the rear end of the loudspeaker in the inner cavity of the connecting sleeve.

At the same time, when the loudspeaker is working, the vibration is buffered by the elastic component, thereby reducing the influence of the vibration caused by the operation of the loudspeaker on the device shell, reducing the equipment noise, and improving the sound quality of the speaker.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described in detail with reference to the accompanying drawings.

[0022] See also Figure 1 - Figure 5 The utility model provides a multifunctional subwoofer speaker with high efficiency in heat dissipation, comprising a speaker body 1 and a shell 2.

[0023] Among them, see Figure 1 - Figure 3 The speaker body 1 includes a loudspeaker 11, a mounting plate 12 is fixedly connected to the front end of the outer wall of the loudspeaker 11, a plurality of groups of heat absorbing teeth 13 are fixedly connected to the rear end of the outer wall of the loudspeaker 11 at intervals, and the end of the heat absorbing teeth 13 close to the mounting plate 12 is fixedly connected to the mounting plate 12, and the outer shell 2 includes a heat dissipation sleeve 21, a plurality of groups of heat dissipation fins 23 are fixedly connected to the inner wall of the heat dissipation sleeve 21 at intervals, and a clamping assembly 22 is installed between two adjacent groups of heat dissipation fins 23. The clamping assembly 22 clamps the heat absorbing teeth 13 to fix the rear end of the loudspeaker 11 in the inner cavity of the heat dissipation sleeve 21, and increases the heat dissipation area of ​​the loudspeaker 11 through the heat absorbing teeth 13 and the heat dissipation fins 23, thereby improving the heat dissipation efficiency of the device.

[0024] It should be noted that the cross-sectional area of ​​the heat dissipation sleeve 21 is equal to the cross-sectional area of ​​the mounting plate 12 , and the heat dissipation sleeve 21 and the rear end surface of the mounting plate 12 are detachably sealed and connected.

[0025] It should also be noted that a buffer pad is provided at the connection between the heat dissipation sleeve 21 and the mounting plate 12 .

[0026] Specifically, please refer to 4. The heat dissipation sleeve 21 includes a connecting sleeve 212. An air outlet screen 211 is provided on the outer wall of the connecting sleeve 212 near the front end. An air inlet grille 214 is fixedly connected to the rear end of the connecting sleeve 212. A heat dissipation fan 213 is installed on the inner cavity of the connecting sleeve 212 near the air inlet grille 214. When the heat dissipation fan 213 is working, external air passes through the air inlet grille 214 and enters the inner cavity of the connecting sleeve 212, and is finally discharged from the air outlet screen 211, thereby completing the heat dissipation.

[0027] It should be noted that the cooling fan 213 includes a mounting frame, a motor and an impeller, and the motor is fixedly connected to the inner wall of the connecting sleeve 212 through the mounting frame.

[0028] For details, please refer to Figure 5 In order to reduce the influence of the vibration generated by the loudspeaker 11 when working on the housing 2, the clamping component 22 includes a clamping plate 221, and a plurality of groups of elastic components 222 are fixedly connected at intervals on the top of the clamping plate 221. The end of the elastic component 222 away from the clamping plate 221 is fixedly connected to the inner wall of the connecting sleeve 212. During installation, the heat absorbing tooth 13 pushes the clamping plate 221 to compress the elastic component 222 so that the clamping plate 221 moves toward the inner wall of the connecting sleeve 212. The compressed elastic component 222 generates a reaction force to push the clamping plate 221 to move away from the inner wall of the connecting sleeve 212, thereby clamping the heat absorbing tooth 13 and fixing the rear end of the loudspeaker 11 in the inner cavity of the connecting sleeve 212. When the loudspeaker 11 generates vibration during operation, it is transmitted to the elastic component 222 through the clamping plate 221. The elastic component 222 deforms to eliminate the vibration, thereby reducing the noise generated by the vibration of the loudspeaker 11 and improving the sound quality of the equipment.

[0029] It should be noted that the loudspeaker 11 itself includes the main functional components of the loudspeaker, such as the speaker, the resonance chamber, the control circuit, the input module, etc., and has the playback function of the loudspeaker. The above-mentioned vibration elimination is only for the vibration generated by the loudspeaker 11 itself due to normal operation, which causes the housing 2 to resonate and thus interferes with the sound quality.

[0030] It should also be noted that the connecting sleeve 212 is made of metal, which can further improve the heat dissipation efficiency of the heat dissipation fins 23 .

[0031] For details, please refer to Figure 5 In order to increase the convenience of installation, a guide slope 223 is provided on the lower end surface of the clamping plate 221. The top of the guide slope 223 is horizontal, and the bottom height of the guide slope 223 increases along the installation direction of the heat absorption tooth 13. By setting the inclined surface, the horizontal resistance of the heat absorption tooth 13 pushing the clamping plate 221 when moving into the connecting sleeve 212 is reduced. A limiting groove 224 is provided on the lower end surface of the guide slope 223. During installation, the heat absorption tooth 13 moves along the limiting groove 224, so that the clamping plate 221 moves more smoothly.

[0032] Principle: Align the heat absorbing tooth 13 with the limiting groove 224, so that the heat absorbing tooth 13 moves along the limiting groove 224 toward the inner cavity of the connecting sleeve 212. When the heat absorbing tooth 13 moves, it pushes the guide slope 223 to compress the elastic component 222 and moves along the heat dissipation fin 23 toward the inner wall of the connecting sleeve 212. At the same time, the compressed elastic component 222 generates a reaction force to push the clamping plate 221 to move away from the inner wall of the connecting sleeve 212, thereby clamping the heat absorbing tooth 13 and fixing the rear end of the loudspeaker 11 in the inner cavity of the connecting sleeve 212. Finally, the front end of the heat dissipation sleeve 21 is sealed and fixedly connected with the rear end of the mounting plate 12 to complete the assembly of the equipment. When the loudspeaker 11 is working, the cooling fan 213 works to draw the external air into the inner cavity of the connecting sleeve 212 through the air inlet grille 214, and the airflow flows along the gap between the heat dissipation fins 23 and the heat absorption teeth 13. The heat dissipation area of ​​the loudspeaker 11 is greatly increased through the heat absorption teeth 13 and the heat dissipation fins 23, and the heat dissipation efficiency is improved. Finally, the airflow is discharged from the air outlet screen 211. At the same time, the vibration generated by the operation of the loudspeaker 11 is transmitted to the elastic component 222 through the guide slope 223 and the clamping plate 221, and is buffered and absorbed by the elastic component 222, thereby greatly reducing the influence of the vibration of the speaker body 1 on the outer shell 2, reducing the noise of the speaker and improving the sound quality of the sound.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
