Abstract: A audio speaker includes two parallel magnetically permeable plates and a diaphragm movably supported parallel to and approximately equidistant from the plates by a surround. A magnet assembly is coupled to the two magnetically permeable plates and passes through an opening in the diaphragm. The magnet assembly includes two magnets that are coupled with two like poles adjacent the diaphragm. A voice coil is coupled around the opening in the diaphragm to move the diaphragm when an electrical current flows in the voice coil. A suspension ring may surround a portion of the magnet assembly with a first end sealed to the diaphragm and an opposing second end sealed to one of the two plates to separate a back volume from a front volume. Some embodiments include several magnetic assemblies passing through the diaphragm with a voice coil and a suspension ring for each magnet assembly.

Abstract: A wearable electronic device includes a band, a gas inlet member, and a gas outlet member. The band defines a sound chamber. The gas inlet member and the gas outlet member are both positioned on the band and communicated with the sound chamber. When the gas inlet member is pressed, air enters into the sound chamber and the sound chamber expands to an expanded state. When the gas outlet member is pressed, the air is exhausted from the gas outlet member and the sound chamber restores to an original state.

Abstract: A portable apparatus including a main body and a receiver is provided. The main body has a surface, an active sound hole and a passive sound hole. The active sound hole and the passive sound hole are both disposed at the surface of the main body. The receiver is disposed inside the main body and arranged for emitting a first sound wave and a second sound wave with the same amplitude and frequency but opposite transmission directions. The first sound wave is transmitted out of the main body via the active sound hole and the second sound wave is guided in the main body and transmitted out of the main body via the passive sound hole.
