[0029] As a common electroacoustic transducer device that converts electrical energy into sound energy, the speaker plays an indispensable role in the sound amplification system. In order to protect the magnetic circuit system of the speaker and prevent dust and foreign matter from entering and affecting the quality of the speaker, a dustproof cloth is usually placed in the basin frame. One end of the dustproof cloth is bonded to the step surface of the basin frame, and the other end is bonded to the opening surface of the U iron to protect the magnetic circuit system. The centering support of the speaker is also bonded to different step surfaces of the basin frame. The structure of multiple bonding surfaces will make the structure of the basin frame complicated and increase the manufacturing cost of the basin frame.

The speaker in the utility model includes a basin frame 10, a magnetic circuit unit 20 and a vibration unit. The basin frame 10 has a housing cavity 11, the housing cavity 11 has an open end, the magnetic circuit unit 20 is arranged in the housing cavity 11, an annular protective member 25 is connected between the magnetic circuit unit 20 and the basin frame 10, and the vibration unit includes a centering support piece 33 and a vibration component, the vibration component is arranged at the open end and the vibration component is suspended in the magnetic circuit unit 20, the centering support piece 33 is sleeved outside the vibration component, and the circumferential outer wall of the centering support piece 33 is attached to the side of the protective member 25 away from the basin frame 10.

[0031] According to the loudspeaker of the present invention, the basin frame 10 can accommodate and fix the magnetic circuit unit 20 and the vibration component. The protective member 25 is connected between the magnetic circuit unit 20 and the basin frame 10, and can protect the magnetic circuit unit 20 to prevent dust, foreign matter, etc. from entering and affecting the quality of the loudspeaker. The circumferential outer wall of the centering support plate 33 is attached to the side of the protective member 25 away from the basin frame 10, so that the protective member 25 is fixed on the basin frame 10, and the centering support plate 33 is fixed on the protective member 25, so that one connecting surface of the basin frame 10 fixes the protective member 25 and the centering support plate 33 respectively. Compared with the existing structure in which the protective member 25 and the centering support plate 33 are respectively connected to the basin frame 10, a connecting surface of the basin frame 10 can be saved, so that the connecting structure is simplified, and the manufacturing cost of the basin frame 10 is saved.

[0032] Specifically, in this embodiment, if Figure 1 As shown, the vibration component includes a compound basin 31 and a voice coil 32. The compound basin 31 is arranged at the open end, one end of the voice coil 32 is connected to one end of the compound basin 31 facing the magnetic circuit unit 20, the other end of the voice coil 32 is suspended in the magnetic circuit unit 20, and the centering support plate 33 is sleeved outside the compound basin 31.

[0033] In some embodiments of the present invention, Figure 2 As shown, the inner wall surface of the basin frame 10 has a first end surface 12, and the first end surface 12 is arranged perpendicularly to the axis of the basin frame 10. The circumferential outer wall of the protective member 25 is attached to the first end surface 12, and the circumferential inner wall of the protective member 25 is connected to the magnetic circuit unit 20. The circumferential outer wall of the centering support 33 is attached to the side of the protective member 25 away from the first end surface 12. In this embodiment, the first end surface 12 is arranged parallel to the horizontal plane, which is convenient for the assembler to install the protective member 25 on the first end surface 12, and at the same time, it is convenient for the assembler to install the centering support 33 on the protective member 25. The centering support 33 in this embodiment is an annular structure, the circumferential inner wall of the centering support 33 is connected to the voice coil 32, and the circumferential outer wall of the centering support 33 is attached to the side of the protective member 25 away from the first end surface 12.

[0034] Specifically, in this embodiment, if Figure 2As shown, the centering support plate 33 includes an elastic portion 331 and a connecting portion 332 . The connecting portion 332 is sleeved and connected to the outside of the elastic portion 331 . The elastic portion 331 is sleeved on the outside of the voice coil 32 . The connecting portion 332 is attached to the side of the protective member 25 away from the first end surface 12 .

[0035] Specifically, in this embodiment, when the magnetic circuit unit 20 is connected to an external power supply, the magnetic circuit unit 20 will drive the voice coil 32 and the compound basin 31 to vibrate back and forth along the axial direction of the basin frame 10. Since the centering support piece 33 is sleeved on the circumference of the compound basin 31 and the centering support piece 33 itself has a certain elasticity, it can help the compound basin 31 to vibrate along the axial direction of the basin frame 10, and can prevent the compound basin 31 from moving in the radial direction of the basin frame 10, thereby providing a limiting function for the vibration of the compound basin 31.

[0036] In some embodiments of the present invention, Figure 2 As shown, the protective member 25 includes a first connection portion 252, a second connection portion 253 and a curved surface portion 251, the first connection portion 252 and the second connection portion 253 are respectively connected to the two ends of the curved surface portion 251 along the radial direction of the protective member 25, the opposite sides of the first connection portion 252 are respectively connected to the first end face 12 and the circumferential outer wall of the centering support piece 33, and the second connection portion 253 is connected to the magnetic circuit unit 20. In this embodiment, the first connection portion 252 is attached to the first end face 12, the second connection portion 253 is attached to the magnetic circuit unit 20, and the curved surface portion 251 is designed to be in the shape of a curved surface, which can increase the area for adsorbing dust and improve the reliability of dust prevention.

[0037] Specifically, in this embodiment, if Figure 1 As shown, the magnetic circuit unit 20 includes a magnetic yoke 21 with a "U"-shaped cross section, a lower magnet 23, a washer 24 and an upper magnet 22 sequentially contained in the magnetic yoke 21, the magnetic yoke 21 includes a bottom and a side wall perpendicular to the bottom, the magnetic yoke 21 is contained in the basin frame 10, and the side wall of the magnetic yoke 21 and the basin frame 10 are open structures, and the second connecting portion 253 of the protective member 25 is attached to the side wall. A magnetic gap is formed between the side wall of the magnetic yoke 21 and the lower magnet 23, the washer 24 and the upper magnet 22, and the voice coil 32 is suspended in the magnetic gap.

[0038] In some embodiments of the present invention, Figure 1 and 2As shown, the curved surface portion 251 is bent toward the side away from the centering arm 33. In this embodiment, if the curved surface portion 251 is bent toward the side of the centering arm 33, it will interfere with the centering arm 33, thereby affecting the layout space. Bending the curved surface portion 251 toward the side away from the centering arm 33 can also allow impurities such as dust to accumulate in the curved surface space formed by the curved surface portion 251, making it easier to collect dust, further preventing dust from entering the magnetic circuit unit 20, and improving reliability.

[0039] In some embodiments of the utility model, a first connection surface is provided between the first connection portion 252 and the centering support piece 33, and the minimum length of the first connection surface is greater than or equal to 2.5 mm along the radial direction of the protective member 25. In this embodiment, the above arrangement can ensure that the connection strength between the protective member 25 and the centering support piece 33 is more stable, and when the magnetic circuit unit 20 drives the vibration assembly to vibrate, the protective member 25 and the centering support piece 33 will not be disconnected by vibration, thereby improving the stability performance.

[0040] In some embodiments of the utility model, there is a second connection surface between the first connection portion 252 and the first end face 12, and the minimum length of the second connection surface is greater than or equal to 2.5 mm along the radial direction of the protective member 25. In this embodiment, the above arrangement can ensure that the connection strength between the protective member 25 and the basin frame 10 is more stable. When the magnetic circuit unit 20 drives the vibration assembly to vibrate, the centering support piece 33 will also vibrate with the vibration assembly. Since the protective member 25 is connected to the centering support piece 33, the connection between the protective member 25 and the basin frame 10 will also be affected. Since the length of the second connection surface is greater than or equal to 2.5 mm, the protective member 25 will not be disconnected from the basin frame 10 due to vibration, thereby improving the stability performance.

[0041] In some embodiments of the utility model, there is a third connection surface between the second connection portion 253 and the magnetic circuit unit 20, and the third connection surface is perpendicular to the axis of the basin frame 10. The minimum length of the third connection surface along the radial direction of the protective member 25 is greater than or equal to 2.5 mm. In this embodiment, the above-mentioned setting can ensure that the connection strength of the third connection surface where the protective member 25 contacts the end face of the side wall is more stable. When the magnetic circuit unit 20 drives the vibration component to vibrate, the centering support piece 33 will also vibrate with the vibration component. Since the protective member 25 is connected to the centering support piece 33 and the protective member 25 is connected to the end face of the side wall, the connection between the protective member 25 and the magnetic yoke 21 of the magnetic circuit unit 20 will also be affected. Since the length of the third connection surface is greater than or equal to 2.5 mm, the protective member 25 and the magnetic yoke 21 will not be disconnected due to vibration, thereby improving the stability performance.

[0042] In some embodiments of the utility model, the inner wall surface of the basin frame 10 has a second end face 13, the second end face 13 is connected to the first end face 12 and is vertically arranged, and the distance between the circumferential outer ring of the centering support piece 33 and the second end face 13 is greater than or equal to 0.5 mm along the radial direction of the protective member 25. In this embodiment, when the magnetic circuit unit 20 drives the vibration component to vibrate, the centering support piece 33 will also vibrate with the vibration component, and the distance between the circumferential outer ring of the centering support piece 33 and the second end face 13 is greater than or equal to 0.5 mm along the radial direction of the protective member 25, which can ensure that the circumferential outer ring of the centering support piece 33 will not collide or interfere with the second end face 13, thereby ensuring the normal operation of the centering support piece 33 and improving reliability.

[0043] In some embodiments of the utility model, the centering support piece 33 and the protective member 25, as well as the protective member 25 and the basin frame 10 are all bonded. In this embodiment, the bonding method is to connect by connecting glue, which can remain stable for a long time and can withstand greater weight and pressure. The adhesive has good plasticity and can be adapted to the bonding of objects of various shapes and sizes, thereby improving versatility and applicability and making the bonding process more convenient.

[0044] Furthermore, the utility model adopts a characteristic surface on the basin frame 10 connected to the centering support piece 33, and bonds the circumferential outer ring of the protective member 25 to this characteristic surface. The centering support piece 33 is then bonded to the protective member 25, and the circumferential inner ring of the protective member 25 is bonded to the end face of the magnetic yoke 21, so as to realize the economical assembly of the protective member 25. This embodiment does not need to design a separate bonding surface, and has a simple structure, which reduces the manufacturing cost of the basin frame 10 compared with the traditional solution. In addition, the protective member 25 and the centering support piece 33 of the traditional solution correspond to two different bonding surfaces. Since the sizes and positions of the two bonding surfaces are different, the gluing machine needs to develop two different programs during assembly. However, the protective member 25 and the centering support piece 33 of this embodiment share a bonding surface, and only one gluing procedure is required, which can simplify the gluing process and further reduce the assembly cost.

[0045] The utility model also provides an electronic device, which has the above-mentioned loudspeaker.

[0046] According to the speaker of the electronic device of the utility model, the basin frame 10 can accommodate and fix the magnetic circuit unit 20 and the vibration component, and the protective member 25 is connected between the magnetic circuit unit 20 and the basin frame 10, and can protect the magnetic circuit unit 20 to prevent dust, foreign matter and the like from entering and affecting the quality of the speaker, wherein the circumferential outer wall of the centering support plate 33 is attached to the side of the protective member 25 away from the basin frame 10, so that the protective member 25 is fixed on the basin frame 10, and the centering support plate 33 is fixed on the protective member 25, so that one connecting surface of the basin frame 10 fixes the protective member 25 and the centering support plate 33 respectively, which can save a connecting surface of the basin frame 10 compared with the existing structure in which the protective member 25 and the centering support plate 33 are respectively connected to the basin frame 10, so that the connecting structure is simplified and the manufacturing cost of the basin frame 10 is saved.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
