AI Technical Summary
Technical Problem
Existing smart glasses speakers suffer from loudness attenuation, far-field leakage, and excessive thickness, affecting privacy and the ability to achieve a slim and lightweight design.
Method used
The device employs a dual-sound-generating-unit design with back-to-back arrangement, including first and second sound-generating units. Each unit has a vibration system and a magnetic circuit system. By utilizing the dual magnetic circuit design and dipole superposition effect, phase cancellation and phase superposition of sound waves are achieved, reducing distortion and thinning the device thickness.
Benefits of technology
It improves loudness, reduces far-field sound leakage, enhances acoustic performance and user privacy protection, and achieves a slim and lightweight design.
