Problems solved by technology
However, due to the structural characteristics of the dynamic sounding device itself, the polarization of the voice coil and diaphragm and the connection of the voice coil lead wires have always been very difficult technical problems to solve
However, the voice coil wire is still prone to problems such as vibration uplift, adhesive degumming, and separation from the load-bearing structure
Moreover, the suspension height of the voice coil wire in the single sounding device is not easy to control

The invention discloses a sound production device monomer, a sound production module and an electronic terminal. The sound production device monomer comprises a magnetic circuit system, a vibration assembly and a circuit board. The magnetic circuit system comprises a magnet yoke, a central magnetic part and a side magnetic part, the central magnetic part and the side magnetic part are arranged onthe magnet yoke, at least one of the central magnetic part and the side magnetic part comprises a permanent magnet, a magnetic gap is formed between the central magnetic part and the side magnetic part, and the sound production device monomer is provided with a lead fixing piece at one side of the side magnetic part away from the magnetic gap; the circuit board is fixedly arranged in the sound production device monomer and is provided with a bonding pad; the vibration assembly comprises a diaphragm and a voice coil. The vibrating diaphragm is configured to vibrate up and down in the sound production device monomer. One end of the voice coil is connected to the vibrating diaphragm, and the other end of the voice coil extends into the magnetic gap of the magnetic circuit system; a lead is led out from the voice coil, bypasses the side magnetic part from the side face of the side magnetic part and penetrates through the lead fixing part, and the lead fixing part is configured to limit thelead from the upper side and the lower side of the lead at least in the height direction of the sound production device single body, so that the reliability of the lead is improved.
Description
technical field [0001] The present invention relates to the field of electroacoustic conversion, and more specifically, the present invention relates to a single sounding device; the present invention also relates to a sounding module and an electronic terminal using the single sounding device. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment, which is a transducer device that converts electrical signals into acoustic signals.
