Sound-generating device

Abstract

This application provides a sound-generating device, which includes a bracket, a mid-bass driver, and a tweeter. The bracket has a first receiving slot and a second receiving slot. The mid-bass driver includes a first magnetic circuit system and a first vibration system. The first magnetic circuit system and the first vibration system are disposed on the bracket through the first receiving slot. The first magnetic circuit system protrudes from the bottom of the bracket and has a first through hole at the bottom, which connects to the first receiving slot. The inner wall of the first receiving slot has a guide groove that connects to the first receiving slot and penetrates to the bottom of the bracket. The first magnetic circuit system, in conjunction with the guide groove, forms a second through hole. The tweeter is disposed on the bracket through the second receiving slot. Thus, the sound-generating device can accommodate both the mid-bass driver and the tweeter within a single bracket, helping to save equipment space and simplify the assembly process.
