Description

Technical Field

[0001] This application belongs to the field of speaker technology, specifically relating to a speaker and a vehicle. Background Technology

[0002] Loudspeakers have a wide range of applications, playing an important role in many fields such as audio systems, home theaters, multimedia equipment, communication equipment, and automobiles. In audio systems, high-quality loudspeakers can provide users with a realistic sound experience, while subwoofers play a crucial role, producing deep, powerful, and impactful low-frequency sound effects that allow people to feel a strong rhythm and atmosphere when listening to music, watching movies, or playing games.

[0003] However, subwoofers need to achieve excellent bass extension, which typically generates significant vibration. In a car, this vibration can cause resonance in the interior and exterior trim and sheet metal, producing unusual noises and negatively impacting the listening experience and driving comfort. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies, this application provides a speaker and a vehicle, which aims to solve the technical problem that excessive speaker vibration can cause resonance of the vehicle body and generate abnormal noise.

[0005] To achieve the above objectives, this application provides a speaker, wherein the speaker includes a cabinet, a speaker assembly, and a vibration damping assembly; the cabinet has a mounting cavity and mounting ears are provided outside the mounting cavity; the speaker assembly includes a first speaker and a second speaker, the first speaker and the second speaker are respectively disposed on opposite sides of the mounting cavity, and the horn openings are arranged opposite each other or back to back, and the first speaker and the second speaker are connected in phase; the vibration damping assembly includes a soft buffer sleeve and a hard connecting sleeve placed inside the soft buffer sleeve, the soft buffer sleeve can be inserted onto the mounting ears, and the hard connecting sleeve can be inserted by a first fastener for fixed connection.

[0006] In the technical solution of this application, the soft buffer sleeve includes a sleeve portion and two snap-fit ​​portions. The sleeve portion is sleeved on the outside of the rigid connecting sleeve. The two snap-fit ​​portions are spaced apart along the length direction of the sleeve portion so that a snap-fit ​​groove is formed between the two snap-fit ​​portions. The mounting ear is formed with a mounting hole, and the edge of the mounting hole is located in the snap-fit ​​groove.

[0007] In the technical solution of this application, the periphery of the snap-fit ​​portion has a guide surface, which is inclined outward from the end face of the snap-fit ​​portion toward the slot.

[0008] In the technical solution of this application, the end face of the snap-fit ​​part is provided with a deformation groove surrounding the sleeve part.

[0009] In the technical solution of this application, the two snap-fit ​​parts are a first snap-fit ​​body and a second snap-fit ​​body, the outer diameter of the first snap-fit ​​body is larger than the outer diameter of the second snap-fit ​​body, and the periphery of the first snap-fit ​​body has a mounting surface, which is inclined outward from the edge of the mounting hole toward the direction away from the slot.

[0010] In the technical solution of this application, a mounting port is formed on one side of the enclosure, and the speaker also includes a passive radiator installed at the mounting port.

[0011] In the technical solution of this application, the passive radiator includes a vibrating part and a connecting part connected together, and the speaker also includes a mounting plate, which is connected to the connecting part, and the mounting plate is detachably connected to the speaker enclosure by a second fastener.

[0012] In the technical solution of this application, the enclosure includes a main body and two mounting parts connected to the main body. The two mounting parts are respectively provided with a first speaker and a second speaker. The mounting parts are recessed inward and have fixing holes for the first speaker and the second speaker to pass through. The first speaker and the second speaker are detachably connected to the mounting parts by a third fastener.

[0013] In the technical solution of this application, the cabinet has a sound outlet hole that communicates with the mounting cavity at the position corresponding to the speaker assembly, and the sound outlet hole is provided with a mesh.

[0014] In addition, this application also provides a vehicle, which includes a vehicle body and a speaker as described above, wherein a rigid connecting sleeve is provided for a first fastener to extend into for detachable connection with the vehicle body.

[0015] Through the above technical solution, the speaker provided in this application embodiment has the following beneficial effects:

[0016] The horn openings of the first and second speakers are positioned opposite or back-to-back. The first and second speakers are connected in phase, meaning the positive terminal of the first speaker is connected to the positive terminal of the second speaker, and the negative terminal of the first speaker is connected to the negative terminal of the second speaker. This ensures that when the first speaker vibrates inward relative to the enclosure, the second speaker also vibrates inward relative to the enclosure. When the speaker assembly is operating, the first and second speakers receive identical signal sources. With precise tuning, the phase and vibration force of the first and second speakers are completely opposite, causing their opposing impact forces to cancel each other out. This significantly attenuates the overall vibration force released by the speaker enclosure, thereby reducing the abnormal noise caused by resonance in the vehicle due to excessive vibration.

[0017] A rigid connecting sleeve is located inside the soft buffer sleeve. The rigid connecting sleeve extends vertically and allows the first fastener to extend into it for secure connection. Through the cooperation of the first fastener and the rigid connecting sleeve, the speaker enclosure can be firmly connected and installed. The rigid connecting sleeve effectively controls the locking depth of the first fastener. Its high structural strength reduces damage to the mounting ears compared to a direct connection between the first fastener and the mounting ear. The soft buffer sleeve passes through the mounting ear, cushioning vibrations from the enclosure. Vibrations transmitted outward from the mounting ear are absorbed by the soft buffer sleeve instead of being directly transmitted to the body panels and interior trim, thus reducing vibration and improving the listening experience and driving comfort.

[0042] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0043] The speaker and vehicle of this application are described below with reference to the accompanying drawings.

[0044] like Figures 1 to 6 As shown, this application provides a speaker 100, wherein the speaker 100 includes a cabinet 10, a speaker assembly 20, and a vibration damping assembly 30. The cabinet 10 forms a mounting cavity 11 and has mounting ears 12 outside the mounting cavity 11; the speaker assembly 20 includes a first speaker 21 and a second speaker 22, the first speaker 21 and the second speaker 22 are respectively disposed on opposite sides of the mounting cavity 11, and the horn openings are arranged opposite each other or back to back, and the first speaker 21 and the second speaker 22 are connected in phase; the vibration damping assembly 30 includes a soft buffer sleeve 31 and a hard connecting sleeve 32 placed inside the soft buffer sleeve 31, the soft buffer sleeve 31 can be inserted onto the mounting ears 12, and the hard connecting sleeve 32 can be inserted by a first fastener for fixed connection.

[0045] The first speaker 21 is disposed on the upper side of the mounting cavity 11, and the second speaker 22 is disposed on the lower side of the mounting cavity 11. Furthermore, the horn openings of the first speaker 21 and the second speaker 22 are positioned opposite each other or back-to-back. The first speaker 21 and the second speaker 22 are connected in phase, meaning the positive terminal of the first speaker 21 is connected to the positive terminal of the second speaker 22, and the negative terminal of the first speaker 21 is connected to the negative terminal of the second speaker 22. This ensures that when the first speaker 21 vibrates inward relative to the enclosure 10, the second speaker 22 also vibrates inward relative to the enclosure 10. When the speaker assembly 20 is operating, the first speaker 21 and the second speaker 22 receive identical signal sources. With precise tuning, the phase and vibration force of the first speaker 21 and the second speaker 22 are completely opposite, and the opposing impact forces cancel each other out. This significantly attenuates the overall vibration force released by the speaker enclosure 100, thereby reducing abnormal noises caused by resonance in the entire vehicle due to excessive vibration force.

[0046] The rigid connecting sleeve 32 is located inside the soft buffer sleeve 31. The rigid connecting sleeve 32 extends vertically and allows the first fastener to be inserted for a fixed connection. Through the cooperation of the first fastener and the rigid connecting sleeve 32, the speaker 100 can be fixedly connected and installed. The rigid connecting sleeve 32 can effectively control the locking depth of the first fastener. The rigid connecting sleeve 32 has high structural strength, reducing damage to the mounting ear 12 compared to the first fastener being directly connected to it. The soft buffer sleeve 31 passes through the mounting ear 12, buffering the vibration of the enclosure 10. This absorbs the vibration transmitted outward from the mounting ear 12, rather than directly transmitting it to the body panels and interior, thus reducing vibration and improving the listening experience and driving comfort.

[0047] Specifically, the first fastener can be a bolt, and the rigid connecting sleeve 32 has a threaded section formed inside. The first fastener is threadedly connected to the threaded section, which facilitates installation and ensures reliable connection. Furthermore, the torque generated by the threaded connection makes the connection between the soft buffer sleeve 31 and the mounting ear 12 more stable and reliable. The rigid connecting sleeve 32 can be made of metal and has high structural strength. The soft buffer sleeve 31 can be made of rubber or silicone and can provide cushioning and absorb vibration.

[0048] In other embodiments, the first fastener may also be a rivet or other fastener.

[0049] In the embodiments of this application, please refer to Figure 5The soft cushioning sleeve 31 includes a sleeve portion 311 and two snap-fit ​​portions 312. The sleeve portion 311 is sleeved on the outside of the rigid connecting sleeve 32. The two snap-fit ​​portions 312 are spaced apart along the length direction of the sleeve portion 311 so that a snap groove 313 is formed between the two snap-fit ​​portions 312. The mounting ear 12 has a mounting hole 13, and the edge of the mounting hole 13 is located in the snap groove 313.

[0050] The sleeve portion 311 extends vertically and is fitted over the connecting sleeve. Two snap-fit ​​portions 312 are spaced apart along the length of the sleeve portion 311, i.e., spaced apart vertically, so that a groove 313 is formed between the two snap-fit ​​portions 312. The mounting ear 12 has a mounting hole 13 that extends vertically. The edge of the mounting hole 13 is located within the groove 313, so that the soft buffer sleeve 31 can be stably and reliably mounted on the mounting hole 13.

[0051] During installation, a snap-fit ​​part 312 is first passed through the mounting hole 13, so that the edge of the mounting hole 13 is located in the slot 313, thereby enabling the soft buffer sleeve 31 to be installed on the mounting hole 13. Then, the hard connecting sleeve 32 is fitted into the sleeve part 311.

[0052] In the embodiments of this application, please refer to Figure 5 The peripheral side of the snap-fit ​​portion 312 has a guide surface 314, which is inclined outward from the end face of the snap-fit ​​portion 312 toward the slot 313.

[0053] The guide surface 314 is located on the periphery of the snap-fit ​​portion 312, and the guide surface 314 is inclined outward from the end face of the snap-fit ​​portion 312 along the direction close to the slot 313. That is, the diameter of the snap-fit ​​portion 312 gradually increases from the end face of the snap-fit ​​portion 312 along the direction close to the slot 313, forming the inclined guide surface 314. By setting the guide surface 314, the snap-fit ​​portion 312 can pass through the mounting hole 13 more smoothly, so that the edge of the mounting hole 13 is located within the slot 313, thereby realizing the installation of the soft buffer sleeve 31 on the mounting hole 13 and improving the installation efficiency of the soft buffer sleeve 31.

[0054] In the embodiments of this application, please refer to Figure 5 The end face of the snap-fit ​​part 312 is provided with a deformation groove 315 surrounding the sleeve part 311. By providing the deformation groove 315, the deformability of the snap-fit ​​part 312 is increased, so that the snap-fit ​​part 312 can pass through the mounting hole 13 more smoothly, thereby further improving the installation efficiency of the soft buffer sleeve 31.

[0055] The number of deformation grooves 315 can be one, two or more. The number of deformation grooves 315 can be flexibly adjusted according to actual needs. This embodiment does not limit the number of deformation grooves 315.

[0056] In the embodiments of this application, please refer to Figure 5 The two snap-fit ​​parts 312 are a first snap-fit ​​body 3121 and a second snap-fit ​​body 3122, respectively. The outer diameter of the first snap-fit ​​body 3121 is larger than that of the second snap-fit ​​body 3122. The periphery of the first snap-fit ​​body 3121 has a mounting surface 3123. The mounting surface 3123 is inclined outward from the edge of the mounting hole 13 toward the direction away from the slot 313.

[0057] The first snap-fit ​​body 3121 is located below the second snap-fit ​​body 3122. The operator can hold the first snap-fit ​​body 3121 to install the soft cushioning sleeve 31, and move the second snap-fit ​​body 3122 from bottom to top so that it passes through the mounting hole 13. The outer diameter of the first snap-fit ​​body 3121 is larger than that of the second snap-fit ​​body 3122, increasing the contact area between the operator and the soft cushioning sleeve 31, making the installation process more convenient.

[0058] The first snap-fit ​​body 3121 has a mounting surface 3123 on its periphery. The mounting surface 3123 is inclined outward from the edge of the mounting hole 13 toward the direction away from the slot 313, so that there is a gap between the first snap-fit ​​body 3121 and the edge of the mounting hole 13, which increases the deformability of the soft buffer sleeve 31 and facilitates installation.

[0059] In this embodiment of the application, a mounting port 14 is formed on one side of the enclosure 10, and the speaker 100 also includes a passive radiator 40 mounted at the mounting port 14.

[0060] like Figure 6 As shown, the mounting port 14 is located on the right side of the enclosure 10. The passive radiator 40 is installed at the mounting port 14. The passive radiator 40 is used to enhance the subwoofer sound pressure level and improve the subwoofer effect. It can achieve the bass effect of a large-diameter enclosure 10 with only a small enclosure volume, thereby saving space and enclosure cost.

[0061] In the embodiments of this application, please refer to the following: Figure 2 and Figure 6 The passive radiant radiator 40 includes a vibrating part 41 and a connecting part 42 connected together. The speaker 100 also includes a mounting plate 50, which is connected to the connecting part 42, and the mounting plate 50 is detachably connected to the cabinet 10 by a second fastener 60.

[0062] The connecting part 42 is connected to the outer edge of the vibrating part 41, and the mounting plate 50 is connected to the connecting part 42. Specifically, the mounting plate 50 can be connected to the connecting part 42 with glue, so that the connection between the mounting plate 50 and the connecting part 42 is tight and reliable. The mounting plate 50 is detachably connected to the housing 10 by the second fastener 60, so as to facilitate the replacement of the passive radiant basin 40 after wear, making the use of the passive radiant basin 40 more flexible and convenient.

[0063] The second fastener 60 can be a bolt, and the second fastener 60 is threadedly connected to the housing 10. The threaded connection has the advantages of convenient installation and reliable connection.

[0064] In other embodiments, the second fastener 60 may be a rivet or other fastener.

[0065] In this embodiment, there are multiple first speakers 21 and second speakers 22, and the number of first speakers 21 and second speakers 22 is the same and they are arranged in a one-to-one correspondence. By setting multiple first speakers 21 and second speakers 22, the sound effect of the speaker 100 is improved.

[0066] like Figure 4 As shown, there are two of each of the first speaker 21 and the second speaker 22, and the sizes of the first speaker 21 and the second speaker 22 can be relatively small. The volume of the enclosure 10 of the speaker 100 is closely related to the size of the speaker. The larger the size of the speaker, the larger the enclosure 10 usually needs to be to ensure a better bass effect. Smaller speakers reduce the volume requirements of the speaker enclosure 100, thereby saving on the volume and material costs of the enclosure 10, and also enabling more flexible placement applications. The inclusion of the passive radiator 40 can compensate for the lack of bass from small speakers.

[0067] In the embodiments of this application, please refer to Figure 6 The housing 10 includes a main body 15 and two mounting parts 16 connected to the main body 15. The two mounting parts 16 are respectively provided with the first speaker 21 and the second speaker 22. The mounting parts 16 are recessed inward and have fixing holes 161 for the first speaker 21 and the second speaker 22 to pass through. The first speaker 21 and the second speaker 22 are detachably connected to the mounting parts 16 by a third fastener.

[0068] The mounting portion 16 is recessed inward, meaning it is recessed from the end face of the main body 15 towards the mounting cavity 11. The mounting portion 16 has a fixing hole 161 through which the first speaker 21 and the second speaker 22 pass. By providing the recessed mounting portion 16 to mount the first speaker 21 and the second speaker 22, the size of the speaker enclosure 100 is reduced. The first speaker 21 and the second speaker 22 are detachably connected to the mounting portion 16 via a third fastener. This detachable connection facilitates replacement of the first speaker 21 and the second speaker 22 after wear, improving their usability.

[0069] The third fastener can be a bolt, and the third fastener is threaded to the mounting part 16.

[0070] In other embodiments, the third fastener may also be a rivet or other fastener.

[0071] In the embodiments of this application, please refer to Figure 2 and Figure 6 The enclosure 10 has a sound outlet 17 that communicates with the mounting cavity 11 at the position corresponding to the speaker assembly 20. The sound outlet 17 is provided with a mesh 70. By providing the mesh 70, dust is prevented from entering the speaker assembly 20, the service life of the speaker assembly 20 is extended, and the sound quality of the speaker assembly 20 is improved.

[0072] Additionally, this application also provides a vehicle, which includes a vehicle body and a speaker 100 as described above, with a rigid connecting sleeve 32 into which a first fastener extends for detachable connection to the vehicle body. The first fastener may be a bolt, which is threadedly connected to the vehicle body, thereby fixing the speaker 100 to the vehicle body.
