Abstract
A miniature speaker, and the miniature speaker includes: frame, and motor assembly and speaker assembly that are fixed to frame. Motor assembly includes vibrating unit and magnetic circuit unit sandwiched between vibrating unit and speaker assembly. The vibrating unit and magnetic circuit unit are flexibly connected in first direction and rigidly connected in second direction. The vibrating unit includes first voice coil, and vibrating unit is driven to vibrate along first direction under action of first voice coil and magnetic circuit unit. The speaker assembly includes second voice coil, motor assembly is driven to vibration along second direction under action of second voice coil and magnetic circuit unit, and first direction is perpendicular to second direction. An X-axis motor and Z-axis motor share magnetic circuit to realize vibration functions of motors in X and Z directions and provide hardware foundation for diversity of vibration signals applied to motors.
