[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-6 The vehicle speaker provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model embodiment provides a vehicle speaker, including: a mounting base 1, a speaker assembly 2, an electrical connection assembly 3, and a mechanical connection assembly 4; The mounting base 1 is configured to connect to the vehicle body and is provided with a wiring terminal 11, which is configured to be electrically connected to the vehicle body's on-board controller; the speaker assembly 2 includes a speaker module 21 and a mounting bracket 22, with the speaker module 21 located on the mounting bracket 22. The electrical connection assembly 3 includes a first electrical connection part 31 and a second electrical connection part 32. The first electrical connection part 31 and the second electrical connection part 32 are detachably connected. The first electrical connection part 31 is disposed on the fixing frame 22 and is electrically connected to the speaker module 21. The second electrical connection part 32 is disposed on the fixing base 1 and is electrically connected to the wiring terminal 11. The mechanical connection assembly 4 includes a first mechanical connection part 41 and a second mechanical connection part 42, which are detachably connected. The first mechanical connection part 41 is disposed on the fixed frame 22, and the second mechanical connection part 42 is disposed on the fixed base 1.

[0028] Understandably, the vehicle body can be provided with a mounting slot that is compatible with the mounting base 1, and locking components such as locking bolts and locking pins can be used to detachably install the mounting base 1 into the mounting slot.

[0029] Both the mounting base 1 and the mounting bracket 22 corresponding to the speaker assembly 2 can be disc-shaped to ensure the aesthetics of the assembly of the mounting base 1 and the speaker assembly 2. The speaker module 21 corresponding to the speaker assembly 2 can be a moving-coil speaker known in the art. The sound-producing end of the speaker module 21 is located on the side of the mounting bracket 22 opposite to the mounting base 1. The speaker module 21 can be detachably mounted on the mounting bracket 22. Of course, to ensure the reliability of the speaker module 21, the speaker module 21 and the mounting bracket 22 can be configured as an integrated structure.

[0030] For the electrical connection assembly 3, both the first electrical connection part 31 and the second electrical connection part 32 are made of metal conductive parts, and the first electrical connection part 31 and the second electrical connection part 32 can be detachably connected by means of plugging or snapping.

[0031] For the mechanical connection assembly 4, both the first mechanical connection part 41 and the second mechanical connection part 42 can be made of metal or plastic. The first mechanical connection part 41 and the second mechanical connection part 42 can be detachably connected by means of plug-in, snap-in or threaded connection.

[0032] The vehicle speaker of this utility model, by setting a mounting base 1 and a speaker assembly 2, and setting an electrical connection assembly 3 and a mechanical connection assembly 4 between the mounting frame 22 of the mounting base 1 and the speaker assembly 2, allows for a detachable connection between the mounting frame 22 and the mounting base 1 through the mechanical connection assembly 4, and also allows for a detachable electrical connection between the speaker module 21 and the mounting base 1 through the electrical connection assembly 3. When the user has a need to modify the vehicle speaker, other types of speaker assemblies 2 can be replaced on the mounting base 1 without changing the installation position of the mounting base 1 on the vehicle body. The entire modification operation is simple and convenient, and can easily realize the physical and electrical connection of the modified speaker assembly 2. It has strong expandability and meets the user's modification needs for the vehicle speaker.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing frame 22 is rotatably disposed relative to the fixing base 1 and can rotate and switch between a first position and a second position; when the fixing frame 22 is in the first position, the first electrical connection part 31 and the second electrical connection part 32 are separated from each other, and the first mechanical connection part 41 and the second mechanical connection part 42 are separated from each other; when the fixing frame 22 is in the second position, the first electrical connection part 31 and the second electrical connection part 32 are connected, and the first mechanical connection part 41 and the second mechanical connection part 42 are connected.

[0034] It is understandable that when a user installs the speaker assembly 2, the speaker assembly 2's mounting bracket 22 is first positioned on the mounting base 1 in the first position, and then the mounting bracket 22 is rotated relative to the mounting base 1 from the first position to the second position, thereby achieving the physical and electrical connection between the mounting bracket 22 and the mounting base 1.

[0035] When the user needs to remove the speaker assembly 2, the fixed bracket 22 can be rotated relative to the fixed base 1 from the second position toward the first position, thereby separating the fixed bracket 22 and the fixed base 1.

[0036] In some embodiments, such as Figure 2 , Figure 5and Figure 6 The vehicle speaker is also provided with a guide structure 6, which includes a first part 61 and a second part 62. The first part 61 and the second part 62 are opposite to each other. The first part 61 is provided on the mounting bracket 22 and the second part 62 is provided on the mounting base 1. The first part 61 and the second part 62 cooperate to guide the mounting bracket 22 to rotate relative to the mounting base 1.

[0037] It is understandable that the cooperation between the first part 61 and the second part 62 of the guide structure 6 can ensure that the fixed frame 22 rotates stably and reliably relative to the fixed base 1.

[0038] In practical applications, the first part 61 and the second part 62 can be configured to slide in the direction of rotation (circumferential direction) of the fixed frame 22. For example, the first part 61 can be a sliding sleeve, and the second part 62 can be a sliding rod extending circumferentially along the fixed frame 22, with the sliding rod movably inserted into the sliding sleeve; or, the first part 61 can be a sliding contact, and the second part 62 can be a sliding groove extending circumferentially along the fixed frame 22, with the sliding contact movably disposed in the sliding groove. Of course, the first part 61 and the second part 62 can also have other sliding fit forms, which will not be listed one by one.

[0039] In some embodiments, such as Figure 2 As shown, the first part 61 includes a limiting post, and the second part 62 includes a guide port. The guide port extends circumferentially along the fixed base 1, and the limiting post is movably inserted into the guide port. When the fixed frame 22 is in the first position, the limiting post and the first end of the guide port abut together. When the fixed frame 22 is in the second position, the limiting post and the second end of the guide port abut together.

[0040] To further ensure that the fixed frame 22 rotates stably and reliably relative to the fixed base 1, the first part 61 can be provided with multiple limiting posts, and the second part 62 can be provided with multiple guide ports. The multiple limiting posts and multiple guide ports are arranged opposite to each other. The multiple limiting posts are located on the side of the fixed frame 22 facing the fixed base 1 and are arranged along the circumference of the fixed frame 22, and the multiple guide ports are arranged along the circumference of the fixed base 1.

[0041] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first electrical connection portion 31 includes a metal socket, and the second electrical connection portion 32 includes a metal plug. When the fixing bracket 22 rotates from the first position to the second position, the metal plug can be inserted into the metal socket; when the fixing bracket 22 rotates from the second position to the first position, the metal plug separates from the metal socket.

[0042] It is understandable that when the metal plug is inserted into the metal socket, the metal plug and the metal socket are electrically connected. The metal socket has wiring pins on one side, which are electrically connected to the signal line of the speaker module 21. The metal socket is electrically connected to the wiring terminal 11 through the conductive wire built into the fixing base 1.

[0043] The metal socket is a flexible socket with a plug interface. Guides are provided on both sides of the plug interface to guide the metal plug into the plug interface for insertion. When the metal plug and metal socket are inserted, the metal plug and metal socket are interference-fitted to ensure the reliability of the electrical connection between them.

[0044] In practical applications, the fixing bracket 22 can be rotated clockwise to control the fixing bracket 22 to rotate from the first position to the second position until the metal plug is inserted into the metal socket; correspondingly, the fixing bracket 22 can be rotated counterclockwise to control the fixing bracket 22 to rotate from the second position to the first position until the metal plug is disengaged from the metal socket.

[0045] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, considering that the speaker module 21 usually has two signal lines, in order to meet the communication requirements of the speaker module 21, this embodiment sets the first electrical connection part 31 to include two metal sockets and the second electrical connection part 32 to include two metal plugs. The two metal plugs and the two metal sockets are arranged opposite to each other. Among them, one of the two metal sockets is electrically connected to one of the signal lines of the speaker module 21, and the other of the two metal sockets is electrically connected to the other signal line of the speaker module 21.

[0046] In practical applications, the terminal block 11 on the mounting base 1 includes a first terminal block and a second terminal block. One of the two metal plugs is electrically connected to the first terminal block, and the other of the two metal plugs is electrically connected to the second terminal block.

[0047] In some embodiments, such as Figure 2 and Figure 4 As shown, in order to facilitate the connection and separation of the first mechanical connection part 41 and the second mechanical connection part 42 by rotation, this embodiment provides that the first mechanical connection part 41 includes an elastic snap-fit ​​member and the second mechanical connection part 42 includes a slot. When the fixing frame 22 rotates from the first position to the second position, the elastic snap-fit ​​can be snapped into the slot; when the fixing frame 22 rotates from the second position to the first position, the elastic snap-fit ​​separates from the slot.

[0048] In some embodiments, such as Figure 4 As shown, the elastic snap-fit ​​component includes a connecting arm and a snap tongue. The connecting arm is located on the side of the fixing frame 22 facing the fixing seat 1, and the snap tongue is located on the connecting arm. The snap tongue is used to snap into the snap groove. The fixing seat 1 is provided with a through hole 102. The connecting arm is configured to pass through the through hole 102. The snap groove is located on one side of the through hole 102 and is located on the side of the fixing seat 1 away from the fixing frame 22.

[0049] It is understood that the connecting arm includes a vertical arm and a horizontal arm. The vertical arm is vertically arranged on the side of the fixing frame 22 facing the fixing seat 1, and the horizontal arm is vertically connected to the vertical arm. The horizontal arm is arranged parallel to the side of the fixing frame 22 facing the fixing seat 1. The latch is arranged on the side of the horizontal arm facing the fixing frame 22.

[0050] In practical applications, the through-hole 102 can be set as a fan-shaped ring. The length of the through-hole 102 along the circumference of the fixing seat 1 can be set to be greater than the length of the horizontal arm so that the connecting arm can be inserted into the through-hole 102. When the connecting arm is inserted into the through-hole 102, the fixing frame 22 and the fixing seat 1 are set in parallel relative to each other. Then, the fixing frame 22 is controlled to rotate from the first position to the second position. Even if the horizontal arm undergoes a slight deformation relative to the vertical arm, it can ensure that the latch crosses the edge of the slot until the latch is engaged in the slot.

[0051] Correspondingly, by rotating the fixing bracket 22 in the opposite direction, it can be ensured that the latch crosses the edge of the slot in the opposite direction until the latch disengages from the slot, even if the horizontal arm undergoes a slight deformation relative to the vertical arm.

[0052] In some embodiments, such as Figure 2 As shown, in order to ensure the reliability of the physical connection between the fixing frame 22 and the fixing base 1, the first mechanical connection part 41 includes multiple elastic snap-fit ​​parts, and the second mechanical connection part 42 includes multiple slots. The multiple elastic snap-fit ​​parts and the multiple slots are arranged one-to-one. This design can achieve simultaneous one-to-one snap-fit ​​of multiple elastic snap-fit ​​parts and multiple slots by rotating the fixing frame 22 from the first position to the second position, and simultaneous separation of multiple elastic snap-fit ​​parts and multiple slots by rotating the fixing frame 22 from the second position to the first position.

[0053] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the vehicle speaker also includes multiple magnetic components 5. Each magnetic component 5 includes a first magnetic component 51 and a second magnetic component 52. The first magnetic component 51 and the second magnetic component 52 can attract each other. The first magnetic component 51 is disposed on the mounting bracket 22, and the second magnetic component 52 is disposed on the mounting base 1. Multiple elastic snap-fit ​​pieces and multiple magnetic suction components 5 are arranged alternately along the circumference of the fixing frame 22, and multiple card slots and multiple magnetic suction components 52 are arranged alternately along the circumference of the fixing base 1. Among them, multiple magnetic components 5 are used to drive the fixing frame 22 to rotate from the first position to the second position.

[0054] It is understandable that when the fixing frame 22 is in the first position, the first magnetic suction member 51 and the second magnetic suction member 52 corresponding to each magnetic suction assembly 5 are misaligned along the axial direction of the speaker module 21.

[0055] When the operator manually drives the fixing frame 22 to rotate from the first position to the second position, the first magnetic 51 and the second magnetic 52 corresponding to each magnetic component 5 gradually move closer to each other. This causes the magnetic attraction force between the first magnetic 51 and the second magnetic 52 corresponding to each magnetic component 5 to gradually increase, thereby achieving the effect of multiple magnetic components 5 jointly driving the fixing frame 22 to rotate from the first position to the second position.

[0056] When the mounting bracket 22 is in the second position, the first magnetic 51 and the second magnetic 52 corresponding to each magnetic assemblies 5 are arranged opposite each other along the axial direction of the speaker module 21. At this time, the magnetic attraction force between the first magnetic 51 and the second magnetic 52 corresponding to each magnetic assemblies 5 reaches its maximum. Based on the magnetic attraction of multiple magnetic assemblies 5, the stability of the connection between the mounting bracket 22 and the mounting base 1 can be ensured.

[0057] In some embodiments, such as Figure 1 As shown, the mounting bracket 22 is provided with a rotation mark 100. The rotation mark 100 can be an arc-shaped arrow mark and is located on the side of the mounting bracket 22 away from the mounting base 1. The rotation mark 100 is used to guide the mounting bracket 22 to rotate from the first position to the second position. The operator can easily install and remove the speaker assembly 2 according to the direction indicated by the rotation mark 100.

[0058] In some embodiments, such as Figure 1 As shown, the fixing frame 22 is provided with a first indicator 200, and the fixing base 1 is provided with a second indicator 300. When the fixing frame 22 is in the first position, the first indicator 200 and the second indicator 300 are arranged opposite to each other.

[0059] It is understood that the first indicator 200 may be provided on the side of the bracket 22 and configured as an arrow indicating one side toward the mounting base 1; correspondingly, the second indicator 300 may be provided on the side of the mounting base 1 and configured as an arrow indicating one side toward the bracket 22.

[0060] When the mounting bracket 22 is in the first position, the first indicator 200 and the second indicator 300 are arranged opposite each other along the axial direction of the speaker module 21 to indicate that the operator has initially completed the assembly of the mounting bracket 22. At this time, it is only necessary to control the mounting bracket 22 to rotate from the first position to the second position to realize the physical connection and electrical connection between the mounting bracket 22 and the mounting base 1.

[0061] In some embodiments, such as Figure 1 and Figure 6 As shown, in order to facilitate the control of the rotation of the fixed frame 22 relative to the fixed base 1, a protruding ridge 221 can be provided around the fixed frame 22. The operator can move the protruding ridge 221 to realize the rotation control of the fixed frame 22.

[0062] Multiple protruding ribs 221 can be provided, and the multiple protruding ribs 221 are arranged circumferentially along the fixing frame 22.

[0063] In some embodiments, such as Figure 5 and Figure 6 As shown, the speaker module 21 is located at the center of the mounting bracket 22 and is an integral structure with the mounting bracket 22; the center of the mounting base 1 is provided with a clearance opening 101, which is used to accommodate at least part of the speaker module 21. This design can achieve a compact design of the entire vehicle speaker.

[0064] In the above embodiments, the electrical connection component 3, the mechanical connection component 4, the guide structure 6, and the magnetic attraction component 5 can all be arranged around the speaker module 21.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
