Ultra-thin external damper-driven loudspeaker combining moving coil and balanced armature
The ultra-thin external spider driver speaker, which combines a dynamic coil and a balanced armature, connects the frame and the diaphragm, solving the problem of reduced driving force during the process of making the speaker thinner and lighter, thus achieving a thinner speaker with better sound quality.

AI Technical Summary
⚠Technical Problem
As existing speakers become thinner and lighter, their driving force decreases, making it difficult to simultaneously achieve the requirements of thinner speakers and better sound quality.
⚗Method used
It adopts an ultra-thin external spider drive structure that combines a moving coil and a moving iron. The external spider connects the frame and the diaphragm, replacing the surround, thus achieving an ultra-thin design. It also utilizes the joint vibration of the magnetic components and the voice coil to improve the driving force.
🎯Benefits of technology
It achieves a thinner and lighter speaker while increasing the driving force by more than 50%, improving sound quality and meeting the needs of ultra-thin applications.

Abstract
Disclosed in the present application is an ultra-thin external damper-driven loudspeaker combining a moving coil and a balanced armature. The loudspeaker comprises a basket, a spring plate, a vibration assembly and a magnetic assembly, wherein the vibration assembly comprises a voice coil, a cone and a damper, the cone being connected to the voice coil but not connected to the basket, and the damper being connected between the cone and the basket and exposed from the basket; and the magnetic assembly is connected to the basket by means of the spring plate and can vibrate relative to the basket. In the present application, the basket is connected to the cone by means of the external damper, such that an ultra-thin structure can be realized; and the magnetic assembly and the voice coil vibrate together, such that a driving force can be greatly improved.
