[0001] The present application relates to the technical field of loudspeakers, in particular to a loudspeaker and a vehicle. BACKGROUND

[0002] With the improvement of people's living standards and the progress of science and technology, the automobile has gradually become the main means of transportation for people, and the types of automobiles have gradually become rich. Among them, the horn is an important part of the automobile, which can be used to issue sound to prompt external vehicles and pedestrians, and to ensure the safety of driving.

[0004] However, since upper contact point and lower contact point need to be in contact constantly, wear will occur between upper contact point and lower contact point due to contact, and when the wear of upper contact point and lower contact point reaches a certain degree, gap will be generated, so that upper contact point and lower contact point are not in good contact, and then cannot be conducted, causing the horn to not work. Utility model content

[0005] The present application aims to provide a kind of loudspeaker and vehicle, to solve the problem that the upper contact point and lower contact point of the horn of the prior art are prone to generate gap due to wear.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0007] On the one hand, the present application provides a kind of loudspeaker, including shell, coil mounting piece, conductive coil, elastic element, first contact point and second contact point. Coil mounting piece is arranged on the shell, and conductive coil is arranged on the coil mounting piece. One end of the elastic element is connected with the coil mounting piece. The first contact point is arranged on the shell and electrically connected with the conductive coil, and the second contact point is connected with the other end of the elastic element and electrically connected with the conductive coil. Among them, the elastic element is used to make the second contact point move towards the direction close to the first contact point, so that the side of the second contact point away from the elastic element abuts against the first contact point.

[0008] According to the above technical means, the shell can provide mounting positions for other components of the loudspeaker, thereby facilitating the mounting of the loudspeaker as a whole. Since one end of the elastic member is connected to the coil mounting member and the other end is connected to the second contact, when the second contact or the first contact is damaged, the second contact can move towards the first contact under the elastic force of the elastic member, so that the first contact and the second contact can always be in abutting contact, thereby ensuring the normal operation of the loudspeaker.

[0009] In a possible implementation, the elastic member includes a spring. One end of the spring is connected to the coil mounting member, and the other end is connected to the second contact.

[0010] According to the above technical means, the second contact and the first contact can be kept in abutting contact through the compression deformation of the spring. It can be understood that when the elastic member includes the spring, the spring can always be in a compressed state.

[0011] In a possible implementation, the coil mounting member is formed with a mounting groove. One end of the elastic member is located in the mounting groove.

[0012] According to the above technical means, by providing the mounting groove on the coil mounting member, the installation of the spring can be more convenient. At the same time, when disassembling, the spring only needs to be taken out from the mounting groove, and the disassembly is also relatively convenient.

[0013] In a possible implementation, the bottom of the mounting groove is formed with a first limiting protrusion. The end of the spring away from the second contact is sleeved on the periphery of the first limiting protrusion.

[0014] According to the above technical means, through the first limiting protrusion, the position of the end of the spring in the mounting groove can be relatively fixed and not easy to shake, thereby ensuring the stability.

[0015] In a possible implementation, the loudspeaker further includes a limiting member. The limiting member is connected to the second contact and located on the side of the second contact close to the spring. The other end of the spring is connected to the limiting member.

[0016] According to the above technical means, by providing the limiting member, the spring can be prevented from directly contacting the second contact, the spring can be prevented from directly exerting relatively concentrated pressure on the second contact, and the second contact can be protected to a certain extent.

[0017] In a possible implementation, the side of the limiting member away from the second contact is formed with a second limiting protrusion. The end of the spring away from the coil mounting member is sleeved on the periphery of the second limiting protrusion.

[0018] According to the technical scheme, the second limiting protrusion can limit the displacement of the end of the spring away from the coil mounting, so that the spring can better apply the elastic force to the second contact in the direction of approaching the first contact.

[0019] In a possible implementation, the loudspeaker further includes a fastener. The fastener penetrates the limiting member and is connected with the second contact. The second contact is connected with the limiting member through the fastener.

[0020] According to the technical scheme, the fastener can connect the second contact and the limiting member together, and the connection is more reliable and stable.

[0021] In a possible implementation, the limiting member is formed with a limiting groove on the side away from the first contact. The limiting groove is annular. The end of the spring away from the coil mounting is located in the limiting groove.

[0022] According to the technical scheme, the end of the spring is located in the limiting groove, which can also play a limiting role, so that the spring can better apply the elastic force to the second contact in the direction of approaching the first contact.

[0023] In a possible implementation, the limiting member is made of an insulating material.

[0024] According to the technical scheme, since the limiting member is made of an insulating material, the elastic member cannot be in communication with the electric circuit, and finally the coil mounting cannot be in communication, so that the temperature rise of the coil mounting caused by electricity is avoided, and the coil mounting is prevented from being damaged.

[0025] In a possible implementation, the loudspeaker further includes an insulating layer. The insulating layer is coated on the end of the spring connected with the limiting member. The end of the spring connected with the limiting member is in contact with the limiting member through the insulating layer.

[0026] According to the technical scheme, since the end of the spring connected with the limiting member is in contact with the limiting member through the insulating layer, the insulating effect can also be achieved, so that the temperature rise of the coil mounting caused by electricity is avoided, and the coil mounting is prevented from being damaged.

[0027] On the other hand, the embodiments of the present application provide a vehicle including the loudspeaker in the above aspect.

[0028] Since the vehicle provided by the embodiments of the present application includes any one of the loudspeakers in the above aspect, the same technical problems as the loudspeaker can be solved, and the same technical effects can be achieved, which will not be described here.

DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0034] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in other than the order illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0035] The embodiments of the present application provide a vehicle. Wherein, the embodiments of the present application do not make specific limitation to the specific type of the vehicle, for example, the vehicle provided by the embodiments of the present application can be an electric vehicle, a hybrid vehicle or a solar vehicle, etc. Meanwhile, the vehicle provided by the embodiments of the present application can also be a vehicle in different forms. For example, the vehicle provided by the embodiments of the present application can be a sedan, a sport utility vehicle (SUV) or a multi-Purpose Vehicles (MPV).

[0036] The vehicle can include a vehicle frame. The vehicle frame can form the overall shape configuration of the outside of the vehicle and form a seating space for accommodating passengers. The vehicle frame is formed with a door structure, and a user can enter and exit from the door structure.

[0037] Furthermore, to enable vehicle propulsion, the vehicle may also include an electric drive system assembly. The electric drive system assembly may include an electric drive system. This electric drive system may include a drive motor and a reducer. The drive motor provides power, and the reducer can be connected to the drive motor. The reducer can regulate the speed, allowing the vehicle to operate at different speeds. Depending on the driving method, the electric drive system can be categorized into front-wheel drive, rear-wheel drive, and four-wheel drive configurations.

[0038] In addition, the vehicle may include a transmission system that can be connected to an electric drive system to transmit power generated by the engine to the wheels.

[0039] To supply power to electrical components such as the drive motor, the vehicle provided in this application embodiment also includes a battery system. The battery system may include a battery pack, which can be used to provide electrical energy. The battery pack can be connected to the vehicle's electric drive system and other electrical components. In this way, the electrical energy from the battery pack can be transferred to various components of the vehicle for power supply.

[0040] Furthermore, the vehicle provided in this application embodiment may also include a horn, which can be used to generate sound to alert external vehicles and pedestrians to give way and ensure driving safety. The horn may include a housing, which provides mounting positions for other components of the horn, thereby facilitating the overall installation of the horn. During installation, the housing can be directly installed onto the vehicle to complete the horn installation.

[0041] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a speaker 100 provided in an embodiment of this application. The speaker 100 may include a coil mounting member 10 and a conductive coil 20. The coil mounting member 10 may be disposed on a housing (not shown in the figure). The conductive coil 20 may be disposed on the coil mounting member 10. For example, Figure 1 As shown, the conductive coil 20 can be sleeved on the coil mounting part 10 to achieve coil installation and fixation. Furthermore, it is known that when the conductive coil 20 is energized, an electromagnetic force can be generated near the conductive coil 20, achieving an attraction effect.

[0042] Continue to refer to Figure 1 The speaker 100 may also include a diaphragm system 30, a loudspeaker 40, a first suction element 50, and a second suction element 60. The diaphragm system 30 may be disposed on the housing and can vibrate and push air to generate sound waves.

[0043] The speaker 40 amplifies and converts signals, enabling people to hear the corresponding sounds. For example... Figure 1 As shown, the speaker 40 can be connected to the diaphragm system 30 and is mounted on the housing via the diaphragm system 30.

[0044] As shown in Figure 1 , the inside of the coil mounting member 10 can be a hollow structure. The first suction member 50 can be connected with the diaphragm system 30. The second suction member 60 can be arranged on the shell. Meanwhile, the first suction member 50 and the second suction member 60 can be arranged at the hollow structure inside the coil mounting member 10 and arranged in opposite directions. The second suction member 60 can play a role of closing the magnetic circuit, thereby improving the performance of the loudspeaker 100.

[0045] Based on this, when the conductive coil 20 is powered to generate magnetic force, the first suction member 50 will move towards the second suction member 60, thereby driving the diaphragm system 30 to move. When the conductive coil 20 is powered off, the first suction member 50 will move away from the second suction member 60, thereby driving the diaphragm system 30 to move.

[0046] It can be understood that the first suction member 50 and the second suction member 60 can be made of magnetic material. For example, the first suction member 50 and the second suction member 60 can be made of a magnet.

[0047] As shown in Figure 2 , Figure 2 is a partial enlarged view of a loudspeaker 100 provided by the embodiment of the present application. The loudspeaker 100 can further include an elastic member 80, a first contact 71 and a second contact 72. One end of the elastic member 80 is connected with the coil mounting member 10. Thus, the elastic member 80 can be installed and fixed through the coil mounting member 10.

[0048] The first contact 71 is arranged on the shell and electrically connected with the conductive coil 20. The second contact 72 is connected with the other end of the elastic member 80 and electrically connected with the conductive coil 20. The second contact 72 can be connected with the diaphragm system 30 and can be in contact or separated from the first diaphragm under the driving of the diaphragm system 30.

[0049] As described above, the first contact 71 and the second contact 72 are electrically connected with the conductive coil 20. The first contact 71 and the second contact 72 can be connected in series in the circuit where the conductive coil 20 is arranged. When the first contact 71 and the second contact 72 are in contact with each other, the conductive coil 20 can be normally powered, and when the first contact 71 and the second contact 72 are disconnected, the conductive coil 20 will be powered off accordingly.

[0050] Based on this, as shown in Figure 1 and Figure 2As shown, when the external circuit is connected, the first contact 71 and the second contact 72 are in the state of mutual abutment, the conductive coil 20 is powered on, and the first attracting member 50 moves towards the second attracting member 60 under the action of the magnetic force. At this time, the first contact 71 and the second contact 72 gradually separate from abutment. When the first contact 71 and the second contact 72 are separated from each other, the conductive coil 20 is powered off, at this time, the first attracting member 50 moves away from the second attracting member 60 along with the diaphragm system 30, in the process of movement, the first contact 71 and the second contact 72 abut again, the conductive coil 20 is powered on again, and the first attracting member 50 moves towards the second attracting member 60 under the action of the magnetic force again, and the reciprocating motion is repeated.

[0051] As mentioned above, since the first contact 71 and the second contact 72 need to be continuously abutted and separated throughout the process, there will be a loss during the abutting process. When the diaphragm system 30 returns to the original position after a certain degree of loss, there will be a gap between the first contact 71 and the second contact 72, which cannot abut each other, so that the conductive coil 20 cannot be normally powered on, and the loudspeaker 100 cannot work. For example, the running stroke of the diaphragm system 30 is about 0.3mm. Therefore, when the maximum distance between the first contact 71 and the second contact 72 in the whole movement process after the loss of the first contact 71 and the second contact 72 is greater than 0.3mm, there will be a gap between the first contact 71 and the second contact 72, which will cause the loudspeaker 100 to not work normally.

[0052] At this time, as shown, Figure 2 Since one end of the elastic member 80 is connected with the coil mounting member 10 and the other end is connected with the second contact 72, when the second contact 72 or the first contact 71 is lost, the second contact 72 can move towards the first contact 71 under the elastic force of the elastic member 80, so that the first contact 71 and the second contact 72 can always maintain abutment and contact, thereby ensuring the normal operation of the loudspeaker 100.

[0053] In addition, since the elastic member 80 is added, the collision force between the first contact 71 and the second contact 72 is increased, which can better clean the oxidation layer on the surface of the mutual contact of the first contact 71 and the second contact 72, and improve the service life and sound quality of the loudspeaker 100.

[0054] In some embodiments, the elastic member 80 includes a spring. One end of the spring is connected with the coil mounting member 10, and the other end is connected with the second contact 72. Thus, the second contact 72 and the first contact 71 can be kept in abutment through the compression deformation of the spring. It can be understood that when the elastic member 80 includes the spring, the spring can always be in a compressed state.

[0055] Of course, the elastic member 80 can also be of other types. For example, the elastic member 80 can also be a spring. The specific type of the elastic member 80 can be selected according to actual conditions, as long as it can provide an elastic force to the second contact 72, so that the second spring moves towards the direction close to the first spring.

[0056] In some embodiments, the coil mounting member 10 is formed with a mounting groove 101. One end of the elastic member 80 is located in the mounting groove 101. In this way, by providing the mounting groove 101 on the coil mounting member 10, the installation of the spring can be more convenient. At the same time, when disassembling, only the spring needs to be taken out from the mounting groove 101, and the disassembly is also relatively convenient. Of course, in other embodiments, one end of the spring can also be directly welded or clamped with the coil mounting member 10, which can be selected according to actual conditions.

[0057] In some embodiments, the bottom of the mounting groove 101 can be formed with a first limiting protrusion 11. The end of the spring away from the second contact 72 is sleeved on the periphery of the first limiting protrusion 11. In this way, through the first limiting protrusion 11, the position of the end of the spring in the mounting groove 101 can be relatively fixed and not easy to shake, ensuring stability.

[0058] Of course, in other embodiments, the bottom of the mounting groove 101 can also be provided with an annular groove. At this time, one end of the spring can also be located in the annular groove. At this time, through the annular groove, the effect of limiting the position of the spring in the mounting groove 101 can also be achieved.

[0059] In some embodiments, the loudspeaker 100 further comprises a limiting member 90. The limiting member 90 is connected with the second contact 72 and located on the side of the second contact 72 close to the spring. The other end of the spring is connected with the limiting member 90. In this way, by providing the limiting member 90, the spring can be prevented from directly contacting the second contact 72, reducing the concentrated pressure of the spring directly applied to the second contact 72, and playing a certain protection role on the second contact 72.

[0060] Of course, in other embodiments, the other end of the spring can also directly contact the second contact 72. At this time, since the limiting member 90 is not needed, the overall composition is simple, and material consumption and cost can be reduced.

[0061] In some embodiments, the side of the limiting member 90 away from the second contact 72 is formed with a second limiting protrusion 91. The end of the spring away from the coil mounting member 10 is sleeved on the periphery of the second limiting protrusion 91. In this way, through the second limiting protrusion 91, the displacement of the end of the spring away from the coil mounting member 10 can be limited, so that the spring can better apply an elastic force to the second contact 72 in the direction close to the first contact 71.

[0062] Of course, in other embodiments, the limiting member 90 can also form a limiting groove on the side away from the first contact 71. The limiting groove is annular. The end of the spring away from the coil mounting member 10 is located in the limiting groove. Thus, by setting the end of the spring in the limiting groove, a limiting effect can also be achieved, so that the spring can better exert the elastic force on the second contact 72 towards the first contact 71.

[0063] In a possible implementation, the limiting member 90 is made of an insulating material. Since the limiting member 90 is composed of an insulating material, the elastic member 80 is not in communication with the electric circuit, and finally the coil mounting member 10 is not in communication, avoiding the temperature rise of the coil mounting member 10 due to electricity, and avoiding damage to the coil mounting member 10.

[0064] In other embodiments, the loudspeaker 100 also includes an insulating layer. The insulating layer is coated on the end of the spring connected to the limiting member 90. The end of the spring connected to the limiting member 90 is in contact with the limiting member 90 through the insulating layer. At this time, since the end of the spring connected to the limiting member 90 is in contact with the limiting member 90 through the insulating layer, an insulating effect can also be achieved, thereby avoiding the temperature rise of the coil mounting member 10 due to electricity, and avoiding damage to the coil mounting member 10.

[0065] As described above, the limiting member 90 is connected to the second contact 72. Therefore, in order to achieve the connection of the limiting member 90 and the second contact 72, in some embodiments, the loudspeaker 100 also includes a fastener (not shown in the figure). The fastener penetrates the limiting member 90 and is connected to the second contact 72. The second contact 72 is connected to the limiting member 90 through the fastener. Thus, the second contact 72 and the limiting member 90 can be connected together through the fastener, and the connection is more reliable and stable. For example, the fastener can be a rivet, and the limiting member 90 and the second contact 72 can be riveted to each other, and the connection is reliable.

[0066] Of course, in other embodiments, the limiting member 90 and the second contact 72 can also be connected to each other through clamping. At this time, the second contact 72 and the limiting member 90 can be provided with corresponding clamping structures, and the specific structure can be designed according to the actual situation, which will not be described further here, as long as the connection between the two can be achieved.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
