Abstract: A speaker module comprising a module housing is disclosed. A speaker unit is accommodated within the module housing. A sound hole of the module is located at a side of the speaker unit. The speaker unit divides a cavity of the entire module into two cavities, namely a front acoustic cavity and a rear acoustic cavity. The front acoustic cavity is in communication with the sound hole. A sound-absorbing cotton is provided in the front acoustic cavity. The sound-absorbing cotton is fixed on the module housing, and is arranged to avoid a vibration space of a diaphragm of the speaker unit. The present invention effectively improves the performance of a sensitivity curve of the module at high frequencies without modifying the structure of the front acoustic cavity, thus not only increasing the acoustic performance of the module, but also simplifying the structure of the front acoustic cavity of the module.

Abstract: An acoustic sensor integrated MEMS microphone structure and a fabrication method thereof. A diaphragm (3e) and back-pole (7) which forms a condenser structure are formed on a substrate (1) having at least one recessed slot (1a) on the top. A sensitive electrode is formed on the substrate (1), the sensitive electrode comprising a fixed portion (3b) fixed on the substrate (1) via a sacrificial layer (2), and a bending portion (3a) inserted into the recessed slot (1a), wherein the bending portion and the side wall of the recessed slot form the condenser structure. The integrated structure integrates the condenser structure of the microphone and condenser structure of the acoustic sensor on a substrate (1), thereby increasing the integration level thereof and reducing the overall size of the package. Meanwhile, the microphone diaphragm (3e) and the sensitive electrode of the acoustic sensor can be fabricated on a same substrate (1) at the same time, from the same material, and using the same fabricating process to increase production efficiency.

Abstract: A linear vibration motor comprising a housing, a vibrator, and a stator fixed on the housing and arranged parallel to the vibrator, push-pull magnets (4) are symmetrically disposed at two ends of the vibrator; push-pull coils (2) surrounding the push-pull magnets are fixedly disposed on the housing at positions corresponding to the push-pull magnets; after the push-pull coils are energized, the push-pull coils and the push-pull magnets generate push-pull forces in a horizontal direction, which provides a driving force for the reciprocating motion of the vibrator in a direction parallel to the plane in which the stator is located. The push-pull structure provides push-pull force for the reciprocation motion of the vibrator, so that an intense vibration force can be achieved.
