2results about How to "Improve the vocal effect" patented technology

This invention provides a loudspeaker comprising a frame, a vibration system, and a magnetic circuit system. The vibration system includes a diaphragm, a voice coil, and a conductive component. The diaphragm includes an annular surround, a fixing portion extending from the outer periphery of the surround towards the frame, and a vibrating portion extending from the inner periphery of the surround towards the voice coil. The conductive component includes a flexible conductive sheet fixed to the vibrating portion along the diaphragm vibration direction near the voice coil, and a conductive coating attached to the diaphragm along the vibration direction near the magnetic circuit system. A voice coil lead is fixed between and electrically connected to the conductive sheet and the conductive coating. The orthographic projection of the conductive sheet onto a plane perpendicular to the vibration direction falls entirely within the range of the orthographic projection of the vibrating portion onto a plane perpendicular to the vibration direction. Compared with the prior art, this invention saves space occupied by the conductive component inside the loudspeaker, facilitates the design of larger magnetic circuit structures, and improves the loudspeaker's sound performance.

This invention discloses a sound-generating module and electronic device, relating to the field of electroacoustic transduction technology. The sound-generating module's sound-generating unit has a magnetic circuit system with a magnetic gap and a through-hole. A first diaphragm assembly and a second diaphragm assembly of the vibration system are respectively located on opposite sides of the magnetic circuit system. A connector passes through the through-hole and connects to the first and second diaphragm assemblies. The periphery of a diaphragm is connected to the magnetic circuit system, and the diaphragm is connected to the connector to seal the through-hole. A first rear cavity is formed between the first diaphragm assembly, the magnetic circuit system, and the diaphragm. A first front cavity is formed between the second diaphragm assembly, the magnetic circuit system, and the diaphragm. A second front cavity is formed between the module housing and the first diaphragm assembly. A second rear cavity is formed between the module housing and the second diaphragm assembly. The module housing has a module sound hole communicating with the second front cavity, and the module sound hole communicates with the first front cavity through the sound outlet of the sound-generating unit. This invention's sound-generating module increases the effective sound-generating area without increasing the product size.
