Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic structural diagram of a speaker according to an embodiment of the present invention, and as shown in fig. 1, the speaker includes: a center frame 01, a voice coil assembly 02, an elastic member 03, and a diaphragm 04, which will be described below.

A middle frame 01 for supporting the entire speaker as a frame;

the voice coil assembly 02 is arranged on the back surface of the vibrating diaphragm 04 and is used for driving the vibrating diaphragm to vibrate when audio current passes through;

the two ends of the elastic part 03 are respectively connected with the voice coil assembly and the middle frame and are used for keeping the balance of the vibration of the voice coil and limiting the transverse swing of the voice coil;

and the back surface of the vibrating diaphragm 04 is connected with the voice coil assembly 02 and is used for vibrating and sounding.

Through the aforesaid adopt the center, the voice coil loudspeaker voice coil subassembly, the speaker that has two magnetic structures of elastic component and vibrating diaphragm, both ends through with elastic component 03 are connected with voice coil loudspeaker voice coil subassembly 02 and center 01 respectively, the purpose of restriction voice coil loudspeaker voice coil 05 horizontal hunting has been reached, thereby stability when having realized reinforcing voice coil loudspeaker voice coil vibration, the technological effect of increase speaker frequency range, and then in having solved the speaker that has two magnetic structures, because do not have the location piece, cause the too big technical problem that leads to wiping the voice coil loudspeaker voice coil phenomenon and the limited frequency range of speaker of voice coil loudspeaker voice coil horizontal amplitude.

As an alternative embodiment, the voice coil assembly 02 may include a voice coil 05 and a support frame 06, wherein the voice coil 05 is fixed on the back of the diaphragm through the support frame 06. When an audio current signal is input, the voice coil 05 vibrates back and forth in the magnetic gap to drive the support frame 06 of the voice coil 05 to vibrate, the support frame 06 pushes the vibration of the vibrating diaphragm 04, and the loudspeaker makes sound through the vibration of the vibrating diaphragm 04.

As an alternative embodiment, the elastic element 03 may be a spring plate, and one end of the spring plate is fixedly connected to the supporting frame 06. For example, one end of the spring plate may be transversely connected to the support frame 06, and when the voice coil 05 vibrates, the spring plate may maintain the vibration directions of the voice coil 05 and the support frame 06 mainly in the vertical direction by providing a transverse force to the support frame 06, so as to maximally prevent the voice coil 05 from swinging during the vibration process.

As an alternative embodiment, the other end of the spring plate may be fixedly connected to the middle frame 01. The voice coil support frame 06 and the middle frame 01 are connected by respectively connecting the two ends of the spring piece with the middle frame 01 and the voice coil support frame 06. When voice coil loudspeaker voice coil 05 vibrated, the spring leaf can play the effect of support between center 01 and voice coil loudspeaker voice coil support frame 06, made voice coil loudspeaker voice coil 05's vibration maintain stably on horizontal, avoided transversely rocking, prevented to wipe the appearance of voice coil phenomenon.

As an alternative embodiment, both ends of the elastic member may be bonded to the voice coil assembly and the middle frame, respectively. Bonding is a process of firmly joining together materials of the same or different kinds by means of the adhesive force generated by an adhesive on a solid surface. The components bonded by the adhesive have flat and smooth appearance, do not reduce functional characteristics, and can avoid concave-convex points at the bonding position.

As an alternative embodiment, the material of the elastic member may be a flexible material with a flexibility parameter adjustable based on the flexibility of the corrugated rim of the diaphragm. In the related art, because of the lack of the positioning support, the diaphragm edge needs to have sufficient rigidity to maintain stability in the lateral direction when the voice coil vibrates. However, the transverse rigidity of the diaphragm corrugated rim is improved, so that the flexibility of the diaphragm corrugated rim is reduced, the vibration frequency of the loudspeaker is too high, and the effective frequency range of sound production is influenced. By adjusting the flexibility parameters of the elastic part, the vibration diaphragm folding ring has a larger selection range in material selection. The elastic part can assist in adjusting the resonance frequency and the power bearing capacity of the loudspeaker through the change of materials, effectively broadens the material flexibility range of the vibrating diaphragm corrugated ring, and meets the requirements of large vibration amplitude and high sound pressure of the loudspeaker and the bearing capacity of high elasticity and high power. For example, when the material of the diaphragm edge is selected, the material of the diaphragm edge with good flexibility can be selected as much as possible, so that the compliance of the voice coil in the vibration process is better.

As an alternative embodiment, the stiffness value of the flexible material is proportional to the damping value of the flexibility of the edge. For example, the damping value of the vibration system of the loudspeaker can be adjusted by adjusting the rigidity value of the elastic element, so that the effect of adjusting the resonance frequency of the loudspeaker is achieved. When the compliance of the diaphragm flexure and the rigidity of the elastic member are adjusted and matched to reach an ideal balance state, the loudspeaker can obtain the maximum vibration amplitude and the minimum resonance frequency without generating the abnormal phenomenon of voice coil swing. This achieves the maximum power carrying capacity and the widest frequency response range, which will also achieve the best sound results in terms of acoustic performance.

As an alternative embodiment, the flexible material comprises at least one of: gummed cloth and rubber materials. The flexible material used as the elastic part material can be selected widely, and the flexible material can be freely selected according to the using conditions of the loudspeaker so as to realize high smoothness and high efficiency. For example, a dipped cloth, a rubber material, red copper or stainless steel may be selected.

According to the embodiment of the utility model, a device is provided, install above-mentioned arbitrary speaker in the device.

As an alternative embodiment, the device comprises at least one of: TV set and intelligent flat board. Traditional speaker can't be well with the product adaptation that thickness is thinner, and according to the utility model discloses the equipment that provides is because the installation has the speaker of two magnetic circuits, therefore thickness is thinner, can use well on requiring product thickness thinner products such as TV set, intelligent flat board, can also design better sound effect in limited thickness space simultaneously.
