Specific embodiment
The technical solution of the utility model is further described below by specific embodiment.
As shown in figures 1 to 6, it is a kind of using coil substitution Hall original part voice coil motor, including pedestal 1, upper metal clips 5,
Lower metal clips 2, coil supporter integral piece 3, permanent magnet 4 and shell 6, coil supporter integral piece 3, permanent magnet 4 are arranged in shell 6
Inside, coil supporter one 3 be set between metal clips 5 and lower metal clips 2, pedestal 1 is encapsulated in 6 bottom of shell
Portion, permanent magnet 4, which is fixed on pedestal 1, constitutes field generator for magnetic, and coil supporter integral piece 3 includes driving portion and test section, institute
Stating driving portion drives coil supporter integral piece 3 to move, and cutting magnetic induction line generates induced current when the test section moves.
The driving portion and the test section are separately positioned, and the driving portion is first coil, and the test section is second
Coil, the first coil are powered, the second coil no power.First coil, the quantity of the second coil be 1 or 2, second
Coil can be located at any positions such as top, the left or right side of first coil.
Such as the end of a thread of figure first coil A1 is connected by wrapping post A3, A4 with B2, B3 of lower metal clips with line tail, and second
The end of a thread of loop A 2 is connected with line tail with B1, B4 of lower metal clips, upper metal clips tie point C1, C2, C3, C4 respectively and
Be electrically connected contact D1, D2, D3, D4 in pedestal are connected, to realize the electrical connection of the end of a thread and line tail and pedestal 1 of first coil A1
