Abstract
The present invention provides a speaker including a housing and a moving iron assembly. The moving iron assembly includes a first magnetic structure and a second magnetic structure, a magnetic induction diaphragm that has a suspension, a first moving iron unit and a second moving iron unit located inside the suspension, and a first coil and a second coil. The side where the first coil and the second coil are away from each other respectively correspond to the first magnetic structure and the second magnetic structure. Compared with the prior art, the magnetic flux control of the moving iron assembly circuit of the speaker is strong, and the driving force is improved.
Claims10
A speaker, comprising a housing and a moving iron assembly fixed in the housing;
- the moving iron assembly including:
- a first magnetic structure and a second magnetic structure which are fixed at two ends of the housing and spaced apart from each other;
- a magnetic conductive diaphragm having a suspension, a first movable iron unit and a second movable iron unit located inside the suspension, the first movable iron unit and the second movable iron unit being located on one side of the housing and horizontally spaced apart;
- an outer peripheral edge of the suspension being fixed to the first magnetic structure and the second magnetic structure, and an inner peripheral edge of the suspension being fixed to the outer peripheral edges of the first movable iron unit and the second movable iron unit respectively;
- the first magnetic structure and the second magnetic structure being magnetized along a vibration direction of the magnetic conductive diaphragm for jointly driving the magnetic conductive diaphragm to vibrate and produce sound;
- and,
- a first coil and a second coil which are respectively spaced to surround the first movable iron unit and the second movable iron unit;
- the first coil being horizontally opposite to the second coil;
- wherein
- a side of the first coil and a side of the second coil which are away from each other is respectively corresponding to the first magnetic structure and the second magnetic structure;
- another side of the first coil and another side of the second coil which are closed to each other forms a sound outlet.
