Abstract
The present invention provides a sound generator having a permeable isolation assembly including a permeable damper, two gums attached to the opposite ends of the permeable damper and PET layer located between two gums. The presence of the PET layer improves the hardness of the permeable damper so as to form adsorption when the permeable isolation component is automatically attached, which is convenient for automatic attachment of the permeable isolation assembly and further improves production efficiency and product qualification rate.
