Abstract
The invention discloses a sound generator having a voice coil. The most outer layer of the voice coil is defined as a tailend layer (last layer), which is wound obliquely from a top of the penult layer adjacent to the diaphragm in a direction away from the diaphragm, so that the high frequency pit of the sound generator is improved. The most outer layer of the voice coil is not completely wound such that the most outer layer reduces the contacting area between the dome and the voice coil, which reduces the split vibration of the dome at high frequency and improves the high frequency-resonance performance.
