AI Technical Summary

Technical Problem

Existing headphones are prone to sound leakage during vibration, and their design makes it difficult to simultaneously guarantee waterproof and dustproof performance.

Method used

By designing the sound leakage generated by the two end walls in the vibration direction of the movement housing to cancel each other out in the far field, and by utilizing the principle of acoustic dipoles, the sound leakage reduction holes on the movement housing can be reduced or eliminated. At the same time, the mass of the movement housing and the stiffness of the transmission plate are adjusted to optimize the frequency response curve of the vibration panel, forming a Helmholtz resonant cavity to weaken the resonance peak.

Benefits of technology

It effectively reduces headphone sound leakage, improves waterproof and dustproof performance, and enhances the acoustic performance of the headphones, especially in the mid-frequency range.

Abstract

This application mainly relates to an earphone, including a core housing, a transducer, a first transducer, and a vibrating panel. The transducer includes a bracket, a second transducer, a magnetic circuit system, and a coil. The bracket is connected to the core housing via the first transducer, the second transducer connects the bracket to the magnetic circuit system, the coil is connected to the bracket, and the vibrating panel is connected to the bracket. In the non-wearing state, the frequency response curve of the vibrating panel has a resonance valley generated by the first transducer, and a first resonance peak and a second resonance peak jointly generated by the first and second transducers. The peak resonant frequencies of the resonance valley, the first resonance peak, and the second resonance peak increase sequentially. This not only helps to avoid the problem of a missing frequency point or frequency band between the two resonance peaks in the aforementioned frequency response curve, but also helps to increase the flatness of the aforementioned frequency response curve between the two resonance peaks, and helps the resonance valley shift to a lower frequency band.
