Problems solved by technology

[0007] The above-mentioned patent literature adopts the one-sided force balance design of the asymmetric magnetic field, emphasizing the feedback of the striking effect, and the magnetic hammer needs more space for movement
At the same time, the single-sided force balance design cannot avoid the friction between the magnetic hammer and the inner wall of the moving cavity, resulting in noise and other quality problems. At the same time, some of its designs use mechanical springs, which cannot avoid reliability risks caused by spring breakage

Embodiment 1

[0094] Example 1: Semi-maglev circular wide-frequency response motor

[0095] like Figure 1-2 , as shown in 4-6 and 3a, the present invention provides a wide-frequency response motor, including a housing 1, a coil 2, a magnetic assembly and a connecting piece 3, the magnetic assembly is arranged in the housing, wherein the magnetic assembly includes a first A magnetic part 4, a second magnetic part 5, a third magnetic part 6 and a fourth magnetic part 7, the left and right sides of the connecting part 3 are respectively provided with a first magnetic part 4 and a second magnetic part 5, wherein the The connecting piece 3 is closely connected with the first magnetic piece 4 and the second magnetic piece 5, and the connecting piece 3, the first magnetic piece 4 and the second magnetic piece 5 constitute a vibrator assembly; the first magnetic piece 4 is far away from the connecting piece 3 One side of the second magnetic part 5 is provided with a third magnetic part 6, and the...

Embodiment 2

[0104] Example 2: The other half of the maglev circular wide-frequency response motor

[0105] The difference between Embodiment 2 and Embodiment 1 is only that the magnetic force of the third magnetic part is different from that of the fourth magnetic part, such as Figure 3b As shown, the distance between the first magnetic piece and the third magnetic piece provided in this embodiment is not equal to the distance between the second magnetic piece and the fourth magnetic piece, although it is not a symmetrical force balance, but in the left-right direction The magnetic force balance is also achieved, so that the vibrator assembly is suspended in the inner cavity of the stator.

Embodiment 3

[0106] Example 3: Magnetic Suspension Circular Wide-Frequency Response Motor

[0107] like Figure 7 As shown, this embodiment provides a wide-frequency response motor, including a housing 1, a coil 2, a magnetic assembly and a connecting piece 3, the magnetic assembly is arranged inside the housing, and the coil 2 is sleeved outside the housing 1.

[0108] Wherein, the magnetic assembly includes a first magnetic piece 4, a second magnetic piece 5, a third magnetic piece 6, a fourth magnetic piece 7, a fifth magnetic piece 8 and a sixth magnetic piece 9, and the connecting piece 3 has two left and right sides. The first magnetic part 4 and the second magnetic part 5 are respectively arranged on the side, wherein, the connecting part 3 is closely connected with the first magnetic part 4 and the second magnetic part 5, and the connecting part 3, the first magnetic part 4 and the The second magnetic part 5 constitutes a vibrator assembly; the first magnetic part 4 is provided wi...

Abstract

The present invention relates to a wide-band motor, which includes a casing, at least one coil, a magnetic assembly and a connecting part; the magnetic assembly is arranged in the casing, the coil is wound outside or inside the casing, and the magnetic assembly includes a first magnetic part , the second magnetic piece, the third magnetic piece and the fourth magnetic piece, the first magnetic piece and the second magnetic piece are respectively arranged on the left and right sides of the connecting piece, the connecting piece, the first magnetic piece and the second magnetic piece A vibrator assembly is formed; a third magnetic member is provided on a side of the first magnetic member away from the vibrator assembly, and a fourth magnetic member is provided on a side of the second magnetic member away from the vibrator assembly. The magnetic field of the motor vibrator assembly and the magnetic field of the motor housing provided by the present invention repel each other to achieve force balance, so that the vibrator is suspended inside the motor. The vibrator assembly is inside the motor housing, and there are repulsive forces at both ends, and the forces at both ends of the vibrator assembly are balanced. , the magnetic field polarity of this structure can be completely reversed.

Description

technical field [0001] The invention relates to the technical field of vibration motors, in particular to a broadband motor. Background technique [0002] Current vibration motors in the electronics industry, such as vibration motors in mobile phones, vibration motors in game controllers and VR controllers, generally use rotor motors or traditional linear motors, and the vibration effect of rotor motors is single. Although traditional linear motors can provide a certain vibration effect experience, the response frequency bandwidth is narrow, which makes it difficult to meet consumers' requirements for wider frequency band vibration effects. At the same time, the traditional linear motor uses a metal or plastic spring structure, which has reliability risks such as spring breakage and noise, and is difficult to manufacture and high in cost. [0003] Patent document CN207691660U discloses a linear vibration motor, the motor includes a housing, a stator assembly accommodated an...
