摘要： Disclosed are a voice coil for a sound producing device and a sound producing device, the sound producing device comprises a voice coil body and a reinforcing portion; the voice coil body comprises a voice coil framework and a voice coil wire; the reinforcing portion comprises a first reinforcing portion and a second reinforcing portion; the first reinforcing portion is provided on the inner side of the voice coil framework, and the second reinforcing portion is provided on the outer side of the voice coil framework; and the reinforcing portion is configured to enhance the strength of the voice coil at high frequencies. Both the inner side and the outer side of the voice coil framework are provided with the reinforcing portions, thereby preventing the voice coil framework from deforming towards the side with lower strength because the strength of one side of the voice coil framework is relatively low.
