Abstract

The invention discloses a voice coil for a sound production device and the sound production device. The sound production device comprises a voice coil body and a reinforcing part, the voice coil bodycomprises a voice coil framework and a voice coil wire, the reinforcing part comprises a first reinforcing part and a second reinforcing part, the first reinforcing part is arranged on the inner sideof the voice coil framework, and the second reinforcing part is arranged on the outer side of the voice coil framework; and the reinforcing part is configured to enhance the high-frequency strength ofthe voice coil framework. According to the invention, the inner side and the outer side of the voice coil framework are provided with the reinforcing parts at the same time, thereby preventing the voice coil framework from deforming towards the side with the low strength because the strength of one side of the voice coil framework is low. The high-frequency strength of the voice coil is improved,and the segmentation vibration generated by the voice coil at high frequency is suppressed. Through the voice coil reinforced by the inner and outer reinforcing parts, the sound distortion of the sound production device can be reduced, and the high-frequency acoustic performance of the sound production device is improved.

Description

technical field [0001] The invention belongs to the technical field of acoustic-electric conversion, and in particular, the invention relates to a voice coil for a sound generating device and a sound generating device. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into sound signals. The audio electric energy causes the cone or diaphragm to vibrate and resonate with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. The loudspeaker is the weakest part of the audio equipment, and it is the most important part for the sound effect. [0003] The voice coil can be said to be the heart of the speaker. The performance of the voice coil will affect the sound pressure frequency characteristics of the speaker, sound pressure level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc., especially the relationship between the speaker's wi...
