The present disclosure provides a motor, including a housing having an accommodating space, a vibrator and a stator that are accommodated in the accommodating space. One of the vibrator and the stator includes a magnetic circuit structure, and the other includes a coil assembly. The coil assembly includes an iron core and a first drive coil and a second drive coil that separately sleeved on two ends of the iron core in a vibration direction of the vibrator, a powering direction of the first drive coil being opposite to a powering direction of the second drive coil. In the present disclosure, the first drive coil and the second drive coil are subjected to Lorentz force in the same direction, thereby vibration of the motor may be improved.

Motor

The present application discloses a linear motor, which includes a housing having a receiving cavity, a vibrator received in the receiving cavity, a stator received in the receiving cavity, and a flexible support connecting to the housing and suspending the vibrator in the receiving cavity. The stator includes an iron core fixed to the housing and a coil winded on the iron core. The iron core includes a first iron core and a second iron core perpendicular to the first iron core, the coil includes a first coil winded on the first iron core and a second coil winded on the second iron core, and the winding directions of the first coil and the second coil are perpendicular to each other. The linear motor of the present invention not only effectively widens the working frequency band of the motor, but also enriches the vibration effect of the motor.

Linear motor

The present invention provides a speaker having a vibrating system and a magnetic circuit system for driving the vibrating system to vibrate and sound. The magnetic circuit system has magnetic gap. The vibrating system includes vibrating assembly and voice coil assembly connected to the vibrating assembly, the voice coil assembly is inserted into the magnetic gap. The magnetic circuit system has a magnetic line concentrating area in the magnetic gap. The voice coil assembly includes a first voice coil connected to the vibrating assembly and a second voice coil arranged on the first voice coil at a side away from the vibrating assembly. if in the magnetic line concentrating area locates only the first voice coil, an electric signal is input only to the first voice coil; if in the magnetic line concentrating area locates only the second voice coil, electric signal is input only to the second voice coil.

Speaker includes a second fixing arm of an elastic supporting member sandwiched between two independently controlled voice coils
