[0032] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0033] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0034] like Figures 1 to 3 As shown, the first exemplary embodiment of the present application provides a speaker, which includes two basin frames 1 and two speaker units 2. Among them, in the two basin frames 1, the two ends of each basin frame 1 along the axial direction are respectively formed as a speaker end and a docking end, and the two basin frames 1 are docked with each other through their respective docking ends to form a speaker skeleton, and the two ends of the speaker skeleton along the axial direction are respectively the speaker ends of the two basin frames 1. In addition, a speaker cavity is formed inside each basin frame 1, and the two speaker units 2 are respectively arranged in the speaker cavities corresponding to the two basin frames 1, and can emit sound toward the corresponding speaker ends.

[0035] It can be seen that the speaker of this exemplary embodiment can be combined into a speaker frame with dual cavities through two basin frames 1, thereby realizing the installation and use of two speaker units 2 in the same speaker frame, so that the speaker of this exemplary embodiment can use the dual speaker units 2 to process different high and low audio respectively, which greatly improves the sound quality effect. On the other hand, it also effectively reduces the overall volume of the speaker, thereby saving the installation space required for the speaker and simplifying the overall structure of the speaker system.

[0036] In one embodiment, referring to Figures 1 to 3 The basin frame 1 includes an inner basin frame 101 and an outer basin frame 102, wherein the inner basin frame 101 and the outer basin frame 102 are roughly trumpet-shaped, and the size of the inner basin frame 101 is smaller than that of the outer basin frame 102, so that the inner basin frame 101 can be arranged in the outer basin frame 102. The key is that the axial outer end of the inner basin frame 101 is formed as an outer open end serving as the above-mentioned speaker end, and the outer open end is open outward, and the axial inner end of the outer basin frame 102 is formed as an inner open end serving as the above-mentioned docking end, and the inner open end docks with the inner open end of another outer basin frame 102 and is connected to each other. The outer basin frame 102 and the inner basin frame 101 respectively include an outer basin cavity 1021 and an inner basin cavity 1011, referring to Figure 2 The axial outer inner end of the inner basin frame 101 is located in the outer basin cavity 1021. By penetrating the axial outer inner end of the inner basin frame 101, the inner basin cavity 1011 and the outer basin cavity 1021 can be connected to form a speaker cavity together.

[0037] In this embodiment, the inner basin frame 101 can be used as a support member to support the speaker unit 2, so that the speaker unit 2 can be fixedly installed in the speaker cavity in the basin frame 1. At the same time, by setting the inner basin cavity 1011 and the outer basin cavity 1021 to be connected, sufficient installation space can be provided for the speaker unit 2. In addition, the outer open end of the inner basin frame 101 serves as a speaker end, allowing the speaker unit 2 to radiate sound toward the outside. The outer open end of the inner basin frame 101 can also play a role in gathering sound, thereby improving the overall sound quality of the speaker.

[0038] Generally, the speaker unit 2 includes a magnetic circuit system 201 and a vibration system 202, and the magnetic circuit system 201 is used to drive the vibration system 202 to operate to generate corresponding audio. In this embodiment, the magnetic circuit system 201 is arranged in the outer basin cavity 1021, and the vibration system 202 is arranged in the inner basin cavity 1011. Specifically, the magnetic circuit system 201 can be installed on the outer wall of the axial outer end of the inner basin frame 101, and the vibration system 202 can be installed on the inner wall of the axial outer end of the inner basin frame 101, so that the speaker unit 2 can be stably arranged in the speaker cavity. In addition, by adopting the above-mentioned partitioned arrangement of the magnetic circuit system 201 and the vibration system 202, the sound quality effect of the speaker unit 2 can be effectively improved.

[0039] It should be noted that the operation mode of the magnetic circuit system 201 driving the vibration system 202 is well known to those skilled in the art and does not belong to the core improvement part of the present application, so it will not be described here in detail.

[0040] In one embodiment, the vibration system 202 includes a sound disc 2021 and a voice coil 2022, and the inner peripheral wall of the inner basin frame 101 is formed with a step portion 1012. The diameter of the sound disc 2021 is set to be not less than the open diameter of the outer open end of the inner basin frame 101, so that the sound disc 2021 can be installed as a whole on the outer open end of the inner basin frame 101 in a manner of covering the opening of the outer open end of the inner basin frame 101. At the same time, the diameter of the voice coil 2022 is set to be not less than the inner diameter of the inner basin frame 101 on the plane where the step portion 1012 is located, so that the voice coil 2022 can be installed on the step surface of the step portion 1012. The sound disc 2021 and the voice coil 2022 can be installed by heat welding, screwing, gluing, etc., which is not limited in this application.

[0041] In one embodiment, referring to Figure 3 The two outer basin cavities 1021 of the two basin frames 1 are interconnected, and the vibration systems 202 of the two speaker units 2 are configured to share the same magnetic circuit system 201, which is arranged in the two interconnected outer basin cavities 1021. Thus, the two vibration systems 202 of the two speaker units 2 can be driven to produce sound at the same time by using the same magnetic circuit system 201. This design can further reduce the design space of the speaker on the basis of ensuring the acoustic performance.

[0042] In one embodiment, referring to Figure 1 and Figure 2 The basin frame 1 includes a fixing plate 103 arranged on the outer edge of the butt end, and the fixing plate 103 is formed with a fixing through hole. The fixing through holes in the two basin frames 1 are aligned and connected to each other. The speaker includes a detachable connecting component 3. The connecting component 3 can be used to connect the two aligned and connected fixing through holes, so that the two basin frames 1 can be detachably connected, thereby improving the layout flexibility.

[0043] Furthermore, the speaker includes a sheet metal part 4 disposed between two basin frames 1, two fixing plates 103 of the two basin frames 1 are respectively disposed on two opposite plate surfaces of the sheet metal part 4, the sheet metal part 4 is formed with a sheet metal through hole that is aligned and connected with the two fixing through holes, and the connecting component 3 is sequentially connected with one fixing through hole, the sheet metal through hole and another fixing through hole. Such an arrangement can further improve the connection strength of the two basin frames 1 and improve the overall stability of the speaker.

[0044] In one embodiment, the speaker further includes a pad 5 disposed between the basin frame 1 and the sheet metal part 4. The pad 5 is a good sound-absorbing material, which can effectively absorb the sound waves generated by the speaker unit 2, especially the high-frequency sound waves, so that the speaker can reduce the sound pressure and treble distortion, and form a sound barrier layer between the two speaker units 2, effectively avoiding the sound of the two speaker units 2 from interfering with each other. At the same time, the pad 5 can form a soft cushion between the basin frame 1 and the sheet metal part 4, avoiding vibration and damage caused by direct impact of the basin frame 1 during the docking process.

[0045] In one embodiment, the two basin frames 1 are butt-jointed with each other by welding, specifically, the two butt ends are welded to each other, so that the two basin frames 1 can form an integrated structure, effectively improving the overall structural strength of the speaker.

[0046] The second exemplary embodiment of the present application also provides a vehicle, which includes the above-mentioned speaker. Obviously, the vehicle has all the technical effects brought by the above-mentioned speaker, so it is not repeated here. Preferably, by arranging the above-mentioned speaker at an appropriate position in the vehicle's cab, on the one hand, it can bring high-quality auditory effects to the driver, and on the other hand, it can effectively save the available space of the vehicle and optimize the layout of the vehicle's audio-visual system.
