For example, in an embodiment, as shown in fig. 3, 4 and 7, the number of the second magnetic members 321 is less than that of the first magnetic members 311, and the second magnetic circuit portion 32 includes one second magnetic member 321, and the magnetizing direction of the second magnetic member 321 is opposite to that of the first magnetic member 311 located at the middle position. In another embodiment, the second magnetic circuit portion 32 may include two second magnetic members 321, the first magnetic circuit portion 31 includes three first magnetic members 311, each second magnetic member 321 is disposed opposite to the gap between two adjacent first magnetic members 311, and the two second magnetic members 321 have the same magnetizing direction and are opposite to the magnetizing direction of the first magnetic member 311 located at the middle position.

Of course, in other embodiments, the first magnetic circuit portion 31 includes five first magnetic members 311, in which case the second magnetic circuit portion 32 may include three or four second magnetic members 321, in which case the second magnetic members 321 of the second magnetic circuit portion 32 are disposed opposite to the gaps between two adjacent first magnetic members 311 in the first magnetic circuit portion 31, and the magnetizing directions of the second magnetic members 321 are the same and are opposite to the magnetizing direction of the first magnetic member 311 located at the middle position, which is not limited herein.

It can be understood that, when the number of the second magnetic members 321 is greater than the number of the first magnetic members 311, the arrangement and the magnetization manner of the first magnetic members 311 are the same as the arrangement and the magnetization manner of the second magnetic members 321 when the number of the second magnetic members 321 is less than the number of the first magnetic members 311 in the above embodiment, and details are not repeated herein.

It should be noted that the arrangement and magnetizing direction of the first magnetic member 311 and the second magnetic member 321 are not limited to the above description, and can be selected and adjusted according to the actual use requirement, which is not specifically limited by the present invention.

It can be understood that, by respectively providing the first magnetic circuit portion 31 and the second magnetic circuit portion 32 on two opposite sides of the vibration system 2, that is, forming magnetic fields with stronger magnetic field strength on two opposite sides of the diaphragm 21, the strength of the magnetic field where the diaphragm 21 is located is further enhanced, so as to further improve the sensitivity of controlling the vibration of the diaphragm 21 and improve the sound quality of the audio output by the speaker 100.

In an embodiment, as shown in fig. 8, the magnetic circuit system 3 further includes a second magnetic circuit portion 32, the second magnetic circuit portion 32 and the first magnetic circuit portion 31 are respectively disposed on two opposite sides of the voice coil 22, the second magnetic circuit portion 32 includes second magnetic members 321, the number of the second magnetic members 321 is the same as the number of the first magnetic members 311, and the magnetizing directions of the first magnetic members 311 and the second magnetic members 321 corresponding to each other up and down are opposite.

In this embodiment, the second magnetic circuit portion 32 and the first magnetic circuit portion 31 are respectively disposed on two opposite sides of the vibration system 2, and the magnetizing directions of the first magnetic member 311 in the first magnetic circuit portion 31 and the second magnetic member 321 in the second magnetic circuit portion 32 which correspond to each other up and down are opposite, that is, the magnetic fields generated by the magnetic member arrays on the surfaces of the two sides of the diaphragm 21 are symmetric, so that the magnetic induction lines of the magnetic field in which the diaphragm 21 is located are distributed more uniformly, and the variation of the magnetic field strength in the vibration direction of the diaphragm 21 has better linearity.

It will be appreciated that by appropriately adjusting the dimensions of the second magnetic circuit portion 32 such that the dimensions of the second magnetic circuit portion 32 are intermediate to the dimensions of the first magnetic circuit portion 31, the effective magnetic field is fully utilized, further increasing the BL value of the loudspeaker 100.

In one embodiment, as shown in fig. 7 and 8, a connection member 312 is disposed between two adjacent first magnetic members 311 to define a fitting gap 313 between the two first magnetic members 311.

In this embodiment, by providing the connecting member 312 between two adjacent first magnetic members 311, the first magnetic members 311 are fixed by the connecting member 312, so as to ensure that the relative positional relationship between the first magnetic circuit portion 31 and the diaphragm 21 is also fixed, thereby ensuring the vibration frequency of the diaphragm 21. Meanwhile, the connecting piece 312 arranged between two adjacent first magnetic pieces 311 is used to define the assembling gap 313 between the two first magnetic pieces 311, on one hand, the first magnetic circuit part 31 is convenient to assemble by using the assembling gap 313, on the other hand, the obstruction of the magnetic field to the air flow is reduced by using the assembling gap 313, so that the loudspeaker 100 has good air compliance, the tone quality of the audio output by the loudspeaker 100 is further improved, the high-pitch effect is improved, and meanwhile, the distortion condition of the audio output by the loudspeaker 100 is relieved.

It can be understood that, as shown in fig. 3 and fig. 4, two adjacent first magnetic members 311 may also be disposed at an interval, so as to form a channel for airflow to circulate between two adjacent first magnetic members 311, so as to allow airflow to circulate in the magnetic field, thereby reducing obstruction of the magnetic field to the airflow, so that the speaker 100 has good air compliance, further alleviating distortion of the audio output by the speaker 100, and improving the sound quality and treble effect of the audio output by the speaker 100.

Of course, in other embodiments, the two adjacent first magnetic members 311 may also be fixed in relative position with respect to each other by gluing, mechanical pressing, and fixing to an external structure, so as to ensure that the relative positional relationship between the first magnetic circuit portion 31 and the second magnetic circuit portion 32 on the two side surfaces of the diaphragm 21 and the diaphragm 21 is also fixed, which is not limited herein.

Alternatively, the pitches of any two adjacent first magnetic members 311 are the same. Of course, in other embodiments, the first magnetic member 311 may also be configured as a ring-like magnetic structure, which is not limited herein. The first 311/second 321 magnetic elements of the first 31 and second 32 magnetic circuit portions may also be arranged such that different areas of the sheet of magnetic material, e.g. powdered ferrite in an adhesive, are exposed to different magnetic fields for magnetization.

Alternatively, the first/second magnetic pieces 311/321 of the first and second

magnetic circuit portions

31 and 32 may be independent magnets, such as magnetic strips, which may be magnetized in different directions and then arranged side by side to effectively form a flat magnetic array with a rotating magnetic field, without limitation.

In one embodiment, two adjacent first magnetic members 311 are disposed adjacent to each other. It is understood that the two adjacent first magnetic members 311 may be fixed by gluing or mechanical pressing, and the structure of the first magnetic circuit portion 31 may be simplified, which is not limited herein.

In one embodiment, there are two voice coils 22, and the two voice coils 22 are respectively disposed on the upper and lower sides of the FPC board 211.

It is understood that the voice coil 22 may be formed by printing, or evaporation, or 3D printing on the surface of the diaphragm 21. The surface of the diaphragm 21 may be provided with the voice coil 22 only, or both surfaces of the surface of the diaphragm 21 may be provided with the voice coil 22, which is not limited herein.

The current is conducted on the voice coil 22 to drive the diaphragm 21 to vibrate towards a predetermined direction so as to generate sound, wherein the direction of the magnetic force exerted on the voice coil 22 is continuously changed by continuously changing the current flowing direction in the voice coil 22, so that the reciprocating vibration of the diaphragm 21 is controlled. It is understood that the greater the number of voice coils 22, the greater the magnetic force driving the diaphragm 21 to vibrate, and the greater the sensitivity of controlling the vibration of the diaphragm 21. However, the size of the surface of the diaphragm 21 and the product specification of the speaker 100 need to be considered, and is not limited herein.

In this embodiment, the material of the lead of the voice coil 22 may be metal such as aluminum, copper, nickel, gold, silver, or an alloy of these metals, which is not limited herein.

Since only the portion of the surface of the diaphragm 21 where the voice coil 22 is disposed will receive the magnetic force, and the portion where the voice coil 22 is not disposed will not receive the magnetic force, the portion of the diaphragm 21 where the voice coil 22 is disposed and the portion where the voice coil 22 is not disposed will exhibit different split vibrations, i.e., the portion of the surface of the diaphragm 21 where the voice coil 22 is disposed will have a larger vibration amplitude than the portion where the voice coil 22 is not disposed. This will cause the frequency response curve of the speaker 100 to generate a peak-valley, which will distort the audio output from the speaker 100, and finally deteriorate the acoustic performance of the speaker 100.

In view of this, the vibration system 2 further includes a reinforcing portion 23, and the reinforcing portion 23 is disposed on the surface of the central portion of the diaphragm 21, wherein the hardness of the reinforcing portion 23 is greater than the hardness of the diaphragm 21, so as to enhance the overall rigidity of the surface of the diaphragm 21, so that the surface of the diaphragm 21 has a uniform vibration amplitude as much as possible, and the diaphragm 21 exhibits overall piston vibration.

Alternatively, the shape of the reinforcement portion 23 may be circular. Of course, the shape of the reinforcing portion 23 may be a stripe, a comb, or the like.

In one embodiment, as shown in FIG. 9, voice coil 22 is formed in a square shape. It is understood that by configuring the voice coil 22 to have a square structure, such that the voice coil 22 includes a first straight side and a second straight side which are connected in sequence, that is, the first conductor segment 221 and the second conductor segment 222 of the voice coil 22 are two opposite first straight sides or two second straight sides, respectively, the configuration is such that the voice coil 22 can effectively increase the magnetic flux.

It is understood that the voice coil 22 may be disposed in an oval shape, and the disposition may be selected according to actual use requirements, which is not limited by the present invention.

The above is only the optional embodiment of the present invention, and not therefore the limit to the patent scope of the present invention, all the concepts of the present invention utilize the equivalent structure transformation of the content of the specification and the attached drawings, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
