MINIATURE SPEAKER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18418364 titled 'MINIATURE SPEAKER
The miniature speaker described in the patent application consists of a frame, a motor assembly, and a speaker assembly fixed to the frame. The motor assembly includes a vibrating unit and a magnetic circuit unit sandwiched between the vibrating unit and the speaker assembly.
- The vibrating unit and magnetic circuit unit are flexibly connected in one direction and rigidly connected in another direction.
- The vibrating unit is driven to vibrate along one direction by the action of the first voice coil and the magnetic circuit unit.
- The speaker assembly includes a second voice coil, which drives the motor assembly to vibrate along a different direction under the action of the second voice coil and the magnetic circuit unit.
- The X-axis motor and Z-axis motor share the magnetic circuit to enable vibration functions in both X and Z directions, providing a hardware foundation for diverse vibration signals applied to the motors.
Potential Applications: - Consumer electronics such as smartphones, tablets, and laptops - Automotive audio systems - Wearable technology like smartwatches and fitness trackers
Problems Solved: - Improved sound quality in a compact form factor - Enhanced vibration functions for a better user experience
Benefits: - Compact size for easy integration into various devices - High-quality sound output - Versatile vibration functions for different applications
Commercial Applications: The technology can be utilized in the development of compact and high-performance audio devices for consumer electronics, automotive, and wearable technology markets.
Questions about the miniature speaker technology: 1. How does the flexible connection between the vibrating unit and magnetic circuit unit contribute to the overall performance of the speaker? 2. What are the advantages of having separate voice coils for the vibrating unit and speaker assembly in terms of sound quality and functionality?
Original Abstract Submitted
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.
