Further, the support members 2 provided corresponding to the positions where the adjacent two voice coils 1 are close to each other connect the corners where the adjacent two voice coils 1 are close to each other.

Further, the support members 2 provided corresponding to the positions where the adjacent two voice coils 1 are close to each other are connected to the short sides of the voice coils 1.

Further, the support members 2 provided corresponding to the positions where the adjacent two voice coils 1 are close to each other connect the corners where the adjacent two voice coils 1 are far from each other.

Further, the support component 2 is a secondary membrane and/or a centering support piece.

From the above description, the support assembly 2 may be selected as desired.

Referring to fig. 1, a first embodiment of the present utility model is as follows: the miniature loudspeaker comprises a basin frame, a magnetic circuit assembly, a vibration assembly and a support assembly 2, wherein the magnetic circuit assembly, the vibration assembly and the support assembly 2 are respectively connected with the basin frame, the vibration assembly comprises a vibrating diaphragm assembly and a plurality of voice coils 1 connected with the vibrating diaphragm assembly, the voice coils 1 with a plurality of numbers are arranged side by side, and the voice coils 1 are positioned in a hollow area of the basin frame; the magnetic circuit assembly is provided with a magnetic gap for the voice coil 1 to move; the support assembly 2 is connected to the voice coil 1.

The outer side surfaces of two adjacent voice coils 1 are connected, the voice coils 1 with a plurality of voice coils are connected and fixed with each other to form a combination, and four corners of the combination are respectively connected with the support component 2. In this embodiment, the number of the voice coils 1 is two, and therefore, the number of the support assemblies 2 is four, and the four support assemblies 2 are respectively disposed corresponding to the four corners of the assembly.

At least one of the top surface, the outer side surface, the inner side surface and the bottom surface of the voice coil 1 and the support component 2 form a joint surface, and optionally, the support component 2 and the voice coil 1 are adhesively connected at the joint surface.

The supporting component 2 is a secondary membrane and/or a centering support piece, namely, the supporting component 2 can be a secondary membrane, a centering support piece or a combined structure of the secondary membrane and the centering support piece. When a centering support is selected as the support member 2, the centering support may be an FPC board; when a sub-film is selected as the support member 2, the sub-film may be either a single-layer film or a multi-layer film, such as a TPU film, PI film, PEEK film, TPEE film, rubber film, or the like.

Example two

Referring to fig. 2 and 3, a second embodiment of the present utility model is a parallel technical solution of the first embodiment, and is different from the first embodiment in that: the connection position of the support assembly 2 and the voice coil 1 is different.

Specifically, the support assemblies 2 are correspondingly disposed at positions where the adjacent two voice coils 1 are close to each other, and the support assemblies 2 disposed at positions where the adjacent two voice coils 1 are close to each other are respectively connected to the adjacent two voice coils 1.

At this time, it is sufficient that the outer side surfaces of the adjacent two voice coils 1 are connected or disconnected. However, it is preferable that the outer side surfaces of the adjacent two voice coils 1 are connected, so that the polarization and rolling vibration phenomena of the micro-speaker can be further improved.

Alternatively, the support members 2 provided corresponding to the positions where the adjacent two voice coils 1 are close to each other connect the corners where the adjacent two voice coils 1 are close to each other.

In this embodiment, the number of the voice coils 1 and the number of the support assemblies 2 are two, the two support assemblies 2 are symmetrically arranged, each support assembly 2 is connected and fixed with two voice coils 1, and the connection position of the support assemblies 2 and the voice coils 1 is located at the corner of the voice coil 1 close to the other voice coil 1.

Optionally, the connection between the support assembly 2 and the voice coil 1 is the bottom surface of the voice coil 1, so as to increase the bonding area between the support assembly 2 and the voice coil 1, and improve the bonding strength between the support assembly 2 and the voice coil 1, in this embodiment, the support assembly 2 has a protrusion 21, and the protrusion 21 is connected to the bottom surface of the long side of the voice coil 1.

Example III

Referring to fig. 4, a third embodiment of the present utility model is a further improvement based on the second embodiment, and is different from the second embodiment in that: the number of the support assemblies 2 is different, and the connection positions of the support assemblies 2 and the voice coil 1 are different.

Not only are adjacent two voice coils 1 provided with the supporting component 2 correspondingly at the positions close to each other, but also the two voice coils 1 positioned at the head and tail are respectively connected with the supporting component 2 at the corners far away from each other. Namely, when the outer side surfaces of two adjacent voice coils 1 are connected, a plurality of voice coils 1 are connected and fixed with each other to form a combination, and the four corners of the combination are respectively connected with the support assemblies 2.

In this embodiment, the outer side surfaces of the adjacent two voice coils 1 may be connected or disconnected.

Example IV

Referring to fig. 5, a fourth embodiment of the present utility model is a further improvement based on the second embodiment, and is different from the second embodiment in that: the connection positions of the support assembly 2 and the voice coil 1 are different, and the widths of the support assembly 2 are different.

The support assembly 2 disposed corresponding to the position where the adjacent two voice coils 1 are close to each other is connected not only to the corner where the adjacent two voice coils 1 are close to each other, but also to the short side of the adjacent two voice coils 1. Thus, the bonding area between the support assembly 2 and the voice coil 1 can be increased, and the bonding strength between the support assembly 2 and the voice coil 1 can be improved.

Example five

Referring to fig. 6, a fifth embodiment of the present utility model is a further improvement based on the fourth embodiment, and the difference between the fifth embodiment and the fourth embodiment is that: the connection positions of the support assembly 2 and the voice coil 1 are different, and the widths of the support assembly 2 are different.

The support assembly 2 disposed corresponding to the position where the adjacent two voice coils 1 are close to each other is connected not only to the short sides of the adjacent two voice coils 1, but also to the corners where the adjacent two voice coils 1 are far from each other. This can increase the bonding area between the support member 2 and the voice coil 1 to a greater extent, and further improve the bonding strength between the support member 2 and the voice coil 1.

Example six

Referring to fig. 7, a sixth embodiment of the present utility model is a parallel technical solution of the first embodiment, and is different from the first embodiment in that: the connection position of the support assembly 2 and the voice coil 1 is different.

In this embodiment, the short side of the voice coil 1 is connected to the support assembly 2. In other embodiments, the connection position of the support assembly 2 and the voice coil 1 may be located on the long side inside the voice coil 1.

In this embodiment, the number of voice coils 1 is two, and the number of support assemblies 2 is four.

Preferably, the outer side surfaces of two adjacent voice coils 1 are connected. Of course, it is also possible that the outer side surfaces of the adjacent two voice coils 1 are not connected.
