[0036] Reference below Figure 1-Figure 6 A loudspeaker 100 according to an embodiment of the present invention is described.

[0037] Reference Figure 1 , Figure 2 and Figure 3 , a loudspeaker 100 according to an embodiment of the present invention comprises: a voice coil 1, a diaphragm 2, a support module 6, a spring 3 and an electrical connection component 4; wherein the voice coil 1 is movable and is configured to drive the diaphragm 2 to vibrate when in motion, and the voice coil 1 is a driving member in the loudspeaker 100. When the voice coil 1 is powered on, the voice coil 1 moves and drives the diaphragm 2 to vibrate, thereby producing sound; the support module 6 is fixed to the voice coil 1, and the support module 6 is configured to define a conductive path electrically connected to the voice coil 1. The spring 3 is connected to the support module 6 to provide a restoring force to the voice coil 1 through the support module 6, so as to ensure that the voice coil 1 can quickly return to a balanced position when in motion, and to ensure that the loudspeaker 100 produces clear and smooth sound; the electrical connection component 4 is electrically connected to the conductive path, and an external power source is suitable for supplying power to the voice coil 1 through the electrical connection component 4 and the conductive path.

[0038] It should be noted that the external power supply can be a vehicle power supply, or a dry battery, a household circuit or other power supply, as long as it can provide current for the speaker 100, and this application does not limit this.

[0039] When the speaker 100 in the embodiment of the present application is working, an external power source supplies power to the voice coil 1 through the electrical connection component 4 and the conductive path, the voice coil 1 moves and drives the diaphragm 2 to vibrate, thereby making a sound, and the elastic wave 3 provides a restoring force for the voice coil 1 to ensure that the voice coil 1 can quickly return to a balanced position when it is moving, thereby ensuring that the sound of the speaker 100 is clear and smooth.

[0040] In the related art, a power supply wire is provided inside the speaker 100 and is connected to the voice coil 1. When the voice coil 1 moves, the power supply wire will cause a large shaking. In order to prevent the wire from touching the diaphragm 2, a larger movement space needs to be reserved for the power supply wire inside the speaker 100.

[0041] In the embodiment of the present application, the electric connection component 4 and the conductive path are used to power the voice coil, that is, the electric connection component 4 and the conductive path replace the function of the power supply wire in the related art. The conductive path is fixed relative to the support module 6, so that the shaking amplitude of the electric connection component 4 is much smaller than the shaking amplitude of the power supply wire in the related art. Therefore, in the embodiment of the present application, the space for avoiding the shaking of the electric connection component 4 can be reduced, thereby reducing the overall volume of the speaker 100.

[0042] In the speaker 100 according to the embodiment of the present invention, the conductive path is fixedly arranged relative to the supporting module 6, thereby reducing the risk of the electrical connection component 4 contacting the diaphragm 2, thereby ensuring the clarity and smoothness of the sound of the speaker 100; and reducing the space inside the speaker 100 for avoiding the electrical connection component 4, thereby effectively reducing the overall design height of the speaker 100, and effectively reducing the overall volume of the speaker 100, thereby ensuring that the speaker 100 can be installed in narrow locations such as the spare tire pit of a vehicle, thereby saving space and making the bass effect of the speaker 100 more powerful and thick, thereby effectively improving the pronunciation effect of the speaker 100.

[0043] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the speaker 100 further includes a basket 5, the diaphragm 2 is fixed to the basket 5, the voice coil 1 and the elastic wave 3 are located in the basket 5, and one end of the electrical connection component 4 is fixed to the basket 5 to be suitable for electrical connection with an external power supply.

[0044] In the embodiment of the present application, the voice coil 1 and the elastic wave 3 are located in the basin frame 5, and the basin frame 5 can protect the voice coil 1 and the elastic wave 3 to prevent the voice coil 1 and the elastic wave 3 from interfering with external structures, thereby ensuring the reliability of the speaker 100.

[0045] In some specific embodiments, the basin frame 5 includes: a first part 51 and a second part 52, and the first part 51 and the second part 52 together define an installation space for the voice coil 1 and the elastic wave 3, that is, the basin frame 5 is assembled from the first part 51 and the second part 52. During the assembly process of the speaker 100, a part of the structure can be first installed on the first part 51, and then the other part of the structure can be installed on the second part 52, and finally the first part 51 is connected to the second part 52 to complete the overall assembly of the speaker 100, which effectively improves the convenience of assembling the speaker 100 and improves the assembly efficiency of the speaker 100.

[0046] Reference Figure 2 , Figure 3 and Figure 4 In some specific embodiments, the damper 3 is constructed as an annular structure, the voice coil 1 is arranged on the radial inner side of the damper 3, and the radial outer side of the damper 3 is connected to the inner wall of the basin frame 5. The annular damper 3 can be used to position the voice coil 1, limit the range of movement of the voice coil 1, and improve the accuracy of the sound of the speaker 100.

[0047] In some embodiments, the electrical connection assembly 4 is fixed to the damper.

[0048] When the speaker 100 is working, the electrical connection component 4 is fixed to the damper 3, and the electrical connection component 4 will not be affected by the movement of the voice coil 1 and will not move significantly. Therefore, in the embodiment of the present application, there is no need to reserve a special activity space for the movement of the electrical connection component 4, which effectively reduces the overall volume of the speaker 100 compared to the related art. The speaker 100 can be installed in a narrow location such as the spare tire pit of a vehicle, which saves space and makes the bass effect of the speaker 100 stronger and thicker, effectively improving the pronunciation effect of the speaker 100.

[0049] In some embodiments, the electrical connection component 4 is a flexible member and is fixed to the elastic wave 3. The first electrical connection end 41 and the second electrical connection end 42 of the electrical connection component 4 are respectively exposed to the elastic wave 3. The first electrical connection end 41 is electrically connected to the conductive path, and the second electrical connection end 42 is suitable for being electrically connected to an external power source.

[0050] In the embodiment of the present application, the electrical connection component 4 is a flexible component, so that the electrical connection component 4 can move and deform together with the damper 3, thereby ensuring the reliability of the power supply of the electrical connection component 4 and the reliability of the fixed connection between the electrical connection component 4 and the damper 3. The first electrical connection end 41 of the electrical connection component 4 is exposed to the damper 3, and the electrical connection component 4 is a flexible component, which is convenient for the staff to electrically connect the first electrical connection end 41 to the conductive path; the second electrical connection end 42 of the electrical connection component 4 is exposed to the damper 3, and the electrical connection component 4 is a flexible component, which is convenient for the staff to electrically connect the second electrical connection end 42 to the external power supply, effectively improving the assembly efficiency of the speaker 100.

[0051] In some embodiments, the electrical connection component 4 is braided and fixed to the wave damper 3 .

[0052] Through the above technical solution, the portion of the electrical connection component 4 fixed to the damper 3 can move along with the movement of the damper 3, which effectively improves the reliability of the connection between the electrical connection component 4 and the damper 3 and further reduces the risk of contact between the damper 3 and the diaphragm 2. In other embodiments, the electrical connection component 4 can also be fixed to the damper 3 by bonding, which is not limited in the present application.

[0053] In some embodiments, the basin frame 5 is provided with an electrical plug terminal 53 , the second electrical connection terminal 42 of the electrical connection assembly 4 is plug-matched with the electrical plug terminal 53 , and the external power source is plug-matched with the electrical plug terminal 53 .

[0054] In the above technical scheme, the second electrical connection end 42 of the electrical connection component 4 is plugged into the electrical plug terminal 53, which improves the convenience of electrical connection between the second electrical connection end 42 and the electrical plug terminal 53 and improves the assembly efficiency of the speaker 100; the external power supply is plugged into the electrical plug terminal 53, which improves the convenience of electrical connection between the external power supply and the electrical connection component 4, that is, the convenience of using the speaker 100 is improved.

[0055] It should be understood that in other embodiments, the second electrical connection terminal 42 can also be fixed to the electrical plug terminal 53 by screws, or fixed to the electrical plug terminal 53 by welding, as long as the second electrical connection terminal 42 is fixedly connected to the electrical plug terminal 53, and the present application does not limit this.

[0056] In some other embodiments, the second electrical connection end 42 may pass through the basin frame 5 , and the second electrical connection end 42 may be directly connected to an external power source as long as it can supply power to the voice coil 1 .

[0057] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the support module 6 includes a first bracket 60 and an intermediate connection component 61, and the intermediate connection component 61 is fixed to the first bracket 60 to define a conductive path.

[0058] The first bracket 60 in the support module 6 serves as a support structure, and the intermediate connecting component 61 serves as a conductive structure. In the embodiment of the present application, the first bracket 60 and the intermediate connecting component 61 are designed as separate parts, which facilitates the overall material design of the support module 6 and reduces the processing cost of the support module 6.

[0059] It should be noted that the intermediate connecting component 61 can be a flexible conductive material, such as a wire; the intermediate connecting component 61 can also be a rigid conductive material, such as a copper sheet; as long as the intermediate connecting component 61 can be used for conduction, in the embodiment of the present application, the intermediate connecting component 61 is fixed to the first bracket 60 to define a conductive path, so that the conductive path is fixed relative to the first bracket 60.

[0060] In some embodiments, the support module 6 includes a first bracket 60 and an intermediate connection component 61, and the intermediate connection component is fixed to the first bracket 60 to define a conductive path. The intermediate connection component 61 is configured as a wire, and the electrical connection component 4 is also configured as a wire, and the intermediate connection component 61 and the electrical connection component 4 are integrally formed, which further reduces the processing cost of the speaker 100.

[0061] It should be understood that in other embodiments, part of the structure of the support module 6 may be made of conductive material to define a conductive path, as long as the conductive path is fixedly arranged relative to the support module 6 .

[0062] In some embodiments, the first bracket 60 extends along the axial direction of the voice coil 1 , the diaphragm 2 is disposed at one end of the first bracket 60 , and the spider 3 is disposed at the other end of the first bracket 60 .

[0063] In the above technical solution, the distance between the elastic wave 3 and the diaphragm 2 is increased by the first bracket 60, which avoids the elastic wave 3 from contacting the diaphragm 2 when moving, ensures the clarity and smoothness of the sound of the diaphragm 2, and improves the reliability of the speaker 100.

[0064] In some specific embodiments, the first bracket 60 is constructed as a ring structure, the first bracket 60 is outermost on the voice coil 1, and the elastic wave 3 is outermost on the first bracket 60. In the embodiment of the present application, the matching method between the first bracket 60 and the voice coil 1 is simple, which facilitates the assembly of the first bracket 60.

[0065] In some embodiments, the voice coil 1 and / or the first bracket 60 are fixedly connected to the diaphragm 2, the voice coil 1 is fixed to the first bracket 60, the elastic wave 3 is fixed to the first bracket 60, the first bracket 60 is located between the voice coil 1 and the elastic wave 3, and the elastic wave 3 provides a restoring force for the voice coil 1 through the first bracket 60.

[0066] Compared with the solution in which the elastic wave 3 is directly connected to the voice coil 1, in the present embodiment, the elastic wave 3 is indirectly connected to the voice coil 1 via the first bracket 60. The first bracket 60 can prevent the elastic wave 3 from interfering with other structures in the basin frame 5 (such as the magnetic circuit component 7). The avoidance of the first bracket 60 allows the magnetic circuit component 7 to be closer to the diaphragm 2 without interfering with the elastic wave 3, thereby further reducing the overall design height of the speaker 100 and effectively reducing the overall volume of the speaker 100.

[0067] It should be noted that the voice coil 1 can be directly fixedly connected to the diaphragm 2, or fixedly connected to the diaphragm 2 through the first bracket 60, or both the voice coil 1 and the first bracket 60 can be fixedly connected to the diaphragm 2, as long as the voice coil 1 can drive the diaphragm 2 to vibrate.

[0068] For example, in some embodiments, the voice coil 1 is fixed to the first bracket 60 , the elastic wave 3 is fixed to the first bracket 60 , the diaphragm 2 is fixed to the first bracket 60 , the voice coil 1 and the diaphragm 2 are spaced apart, and the voice coil 1 drives the diaphragm 2 to vibrate through the first bracket 60 .

[0069] In the embodiment of the present application, the voice coil 1 is connected to the diaphragm 2 via the first bracket 60 , which can reduce the size of the voice coil 1 in the axial direction and reduce the manufacturing cost of the voice coil 1 .

[0070] In other embodiments, a connecting ring 8 is provided at the end of the voice coil 1, and an inserting groove 81 is provided on the side of the connecting ring 8 facing the voice coil 1. The voice coil 1 is inserted into the inserting groove 81 and bonded to the inner wall of the inserting groove 81, and the side of the connecting ring 8 facing away from the voice coil 1 is bonded to the diaphragm 2.

[0071] In the embodiment of the present application, the voice coil 1 is directly fixedly connected to the diaphragm 2, and the connection area between the voice coil 1 and the diaphragm 2 is increased by the connecting ring 8, thereby improving the stability of the connection between the voice coil 1 and the diaphragm 2.

[0072] In other embodiments, the elastic wave 3 is fixedly connected to the first bracket 60, the first bracket 60 is fixedly connected to the diaphragm 2, the diaphragm 2 is also fixedly connected to the voice coil 1, the voice coil 1 is not directly fixedly connected to the first bracket 60, and the voice coil 1 is fixedly connected to the intermediate connecting component 61 of the supporting module 6. In the embodiment of the present application, the part of the intermediate connecting component 61 located outside the first bracket 60 is made of flexible material, so that the voice coil 1 can move relative to the first bracket 60.

[0073] In the embodiment of the present application, the elastic wave 3 provides a restoring force for the voice coil 1 through the first bracket 60 and the diaphragm 2. In the embodiment of the present application, the diaphragm 2 can assist the elastic wave 3 in restoring, thereby reducing the deformation amplitude of the elastic wave 3, thereby further reducing the overall design height of the speaker 100, and further reducing the overall volume of the speaker 100.

[0074] Reference Figure 5 and Figure 6 In some embodiments, the first bracket 60 is provided with an intermediate connection component 61, and the intermediate connection component 61 is electrically connected to the electrical connection component 4 and the voice coil 1 respectively, and the electrical connection component 4 is electrically connected to the voice coil 1 through the intermediate connection component 61. The intermediate connection component 61 can be a wire, a copper sheet or other conductive structure pre-fixed to the first bracket 60, and the present application is not limited thereto.

[0075] Through the above technical solution, the first electrical connection end 41 only needs to be electrically connected to the intermediate connection component 61 to achieve electrical connection with the voice coil 1. There is no need to fix the portion of the first electrical connection end 41 extending along the axial direction of the first bracket 60 to the first bracket 60, which effectively improves the overall assembly efficiency of the speaker 100.

[0076] In some embodiments, the support module 6 includes a first bracket 60 and an intermediate connection component 61, wherein the intermediate connection component 61 is fixed to the first bracket 60 to define a conductive path. A receiving groove 65 is defined in the first bracket 60, and a portion of the intermediate connection component 61 is located in the receiving groove 65.

[0077] In the embodiment of the present application, the arrangement path of the intermediate connection component 61 is defined by defining the receiving groove 65 in the first bracket 60, so that the intermediate connection component 61 can define a conductive path. In addition, part of the intermediate connection component 61 is located in the receiving groove 65, which also improves the reliability of the connection between the intermediate connection component 61 and the first bracket 60.

[0078] It should be understood that the intermediate connection component 61 can also be fixed to the first bracket 60 by bonding, snapping, screwing or other means, and the present application is not limited to this.

[0079] In some specific embodiments, the intermediate connection component 61 is connected to the first bracket 60 by injection molding.

[0080] Through the above technical solution, the reliability of the connection between the intermediate connection component 61 and the first bracket 60 is further improved, and the convenience of assembling the speaker 100 is further improved.

[0081] In some embodiments, the speaker 100 further includes a magnetic circuit assembly 7 , which magnetically cooperates with the voice coil 1 to make the voice coil 1 movable, and the connection between the conductive path and the voice coil is located at the end of the voice coil away from the magnetic circuit assembly 7 .

[0082] When the voice coil 1 is powered, the magnetic cooperation between the magnetic circuit assembly 7 and the voice coil 1 drives the voice coil 1 to move, thereby driving the diaphragm 2 to vibrate and produce sound. In the embodiment of the present application, the connection between the conductive path and the voice coil is located at the end of the voice coil away from the magnetic circuit assembly 7, which reduces the risk of interference between the conductive path and the magnetic circuit assembly 7.

[0083] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the speaker 100 further includes a magnetic circuit assembly 7, which includes a first magnetic component 71 and a second magnetic component 72. The first magnetic component 71 is provided with a housing cavity for accommodating the second magnetic component 72, and a magnetic circuit gap 73 is provided between the outer peripheral wall of the second magnetic component 72 and the inner wall of the housing cavity; a portion of the voice coil 1 is movably disposed in the magnetic circuit gap 73.

[0084] In the embodiment of the present application, the structure of the magnetic circuit assembly 7 is simple, which reduces the cost of the speaker 100.

[0085] In some embodiments, a portion of the support module 6 facing the magnetic circuit component 7 is provided with an escape cavity 64 for escaping the magnetic circuit component 7 .

[0086] Through the above technical solution, when the voice coil 1 drives the first bracket 60, the elastic wave 3, and the diaphragm 2 to move, the voice coil 1 moves in the magnetic circuit gap 73, the diaphragm 2 vibrates above and away from the magnetic circuit assembly 7, the elastic wave 3 moves on the outside of the first magnetic component 71, and the support module 6 can avoid the magnetic circuit assembly 7 by avoiding the cavity 64, thereby avoiding the risk of interference between the support module 6 and the magnetic circuit assembly 7, thereby ensuring the reliability of the use of the speaker 100.

[0087] In some specific embodiments, the support module 6 includes a first bracket 60, which includes a main body portion 62 and a connecting portion 63. The main body portion 62 is formed in a cylindrical shape and is placed on the voice coil. The connecting portion 63 is located on the inner circumferential wall of the main body portion 62. The connecting portion 63 is located at one end of the main body portion 62 away from the magnetic circuit assembly 7. The connecting portion 63 extends toward the voice coil 1 and is fixedly connected to the voice coil. The main body portion 62 and the connecting portion 63 define an avoidance cavity 64.

[0088] In the embodiment of the present application, the limiting method of avoiding the cavity 64 is simple, which reduces the difficulty of processing the supporting module 6 and reduces the cost of the speaker 100.

[0089] Optionally, the receiving groove 65 extends from the main body portion 62 to the connecting portion 63 , so that the intermediate connecting assembly 61 can be electrically connected to the voice coil 1 .

[0090] In some of the above embodiments, the voice coil 1 is fixedly connected to the first bracket 60, and in some of the above embodiments, the voice coil 1 is not fixedly connected to the first bracket 60. In the embodiment in which the voice coil 1 is fixedly connected to the first bracket 60, the connecting portion 63 can not only be used to restrict the intermediate connecting component 61, but also be fixedly connected to the voice coil 1. The connecting portion 63 can be fixedly connected to the voice coil 1 by bonding, clamping, etc., and this application does not limit this. In the embodiment in which the voice coil 1 is not fixedly connected to the first bracket 60, the connecting portion 63 is only used to restrict the intermediate connecting component 61.

[0091] In some embodiments, the conductive path is provided with an external electrical connection end 611 exposed from the main body portion 62 and the connection portion 63 , and the voice coil 1 and the electrical connection component 4 are electrically connected to the external electrical connection end 611 , respectively.

[0092] In the embodiment of the present application, two ends of the conductive path are respectively exposed to the main body portion 62 and the connecting portion 63 , so as to facilitate the connection between the conductive path and the voice coil 1 and the electrical connection component 4 , which is beneficial to improving the assembly efficiency of the speaker 100 .

[0093] In some further embodiments, at least one of the main body portion 62 and the connecting portion 63 is provided with a weight-reducing hole 66 .

[0094] Through the above solution, the weight of the support module 6 is effectively reduced, which facilitates the support module 6 to move with the voice coil 1 and reduces energy loss. In addition, the design of the weight-reducing hole 66 can also save the material of the support module 6, which is beneficial to reducing the cost of the speaker 100.

[0095] In some specific embodiments, a plurality of weight-reducing holes are provided at intervals around the main body portion, and a plurality of weight-reducing holes are also provided at intervals around the connecting portion, which further reduces the weight of the supporting module and reduces the cost of the speaker.

[0096] In some specific embodiments, the diaphragm 2 is constructed as a flat diaphragm 2 , which further reduces the design height of the loudspeaker 100 and further reduces the volume of the loudspeaker 100 .

[0097] In some specific embodiments, a convex edge structure 21 is provided on the peripheral side of the diaphragm 2, and the convex edge structure 21 protrudes toward the side away from the voice coil 1; in other embodiments, a concave edge structure is provided on the peripheral side of the diaphragm 2, and the concave edge structure protrudes toward the side close to the voice coil 1. The convex edge structure 21 or the concave edge structure improves the elasticity of the diaphragm 2 and improves the vibration effect of the diaphragm 2.

[0098] The vehicle according to the embodiment of the present invention includes the speaker 100 in the above technical solution.

[0099] According to the vehicle of the embodiment of the present invention, at least a portion of the electrical connection component 4 in the speaker 100 is fixed to the elastic wave 3, so that the electrical connection component 4 is prevented from contacting the diaphragm 2, and the speaker 100 is prevented from making noise, thereby ensuring that the speaker 100 makes clear and smooth sound. In addition, there is no need to reserve a special activity space for the electrical connection component 4 in the speaker 100, which can effectively reduce the overall design height of the speaker 100, effectively reduce the overall volume of the speaker 100, and ensure that the speaker 100 can be installed in narrow locations such as the spare tire pit of the vehicle. While saving space, the bass effect of the speaker 100 can be made stronger and thicker, effectively improving the pronunciation effect of the speaker 100.

[0100] In some specific embodiments, the speaker 100 is disposed in a spare tire well, a side door panel, or other cavities of the vehicle.

[0101] In a cavity of the same size, compared with the speaker 100 in the related art, the speaker 100 provided in the present application is thinner in height and smaller in size. When the speaker 100 is working, the sound emitted will be thicker, so that the low-frequency output of the speaker 100 is lower and the sound quality is better.
