Description

Technical Field

[0001] This utility model relates to the field of electroacoustic converter technology, and in particular to a sound generating unit. Background Technology

[0002] As a commonly used electroacoustic transducer that converts electrical energy into sound energy, the sound-generating unit plays an indispensable role in the sound amplifier system.

[0003] The sound-generating module includes a module housing and a sound-generating unit disposed within the module housing. To improve the acoustic performance of the sound-generating module, existing technologies fill the rear cavity of the module housing with sound-absorbing particles, thereby increasing the virtual rear cavity of the sound-generating module. To prevent the sound-absorbing particles from entering the sound-generating unit and causing noise, existing technologies add three-dimensional mesh or metal mesh components at the leakage holes of the sound-generating unit. The addition of three-dimensional mesh or metal mesh components undoubtedly makes the structure of the sound-generating unit more complex and inconvenient to assemble. Utility Model Content
