Abstract

The invention discloses a sound production apparatus and a manufacturing method thereof. The sound production apparatus comprises a substrate and a vibrating diaphragm formed on the substrate in a deposition manner, wherein the sound production apparatus further comprises a coil connected to the vibrating diaphragm, the coil is combined with the vibrating diaphragm in a manner of deposition, etching or magnetron sputtering, and the coil is helical from the middle to the outer side; the sound production apparatus further comprises a first magnet component correspondingly arranged with the coil; and the first magnet component is configured to provide an Ampere force whose direction is vertical to the vibrating diaphragm for the coil. According to the sound production apparatus disclosed by the invention, when alternating current signals are input to the coil, the magnetic line of force emitted by the first magnet component penetrates through the coil, so that the coil is applied with a corresponding Ampere force and drives the vibrating diaphragm to vibrate so as to realize the sound production of the vibrating diaphragm. The sound production apparatus disclosed by the invention breaks through the installation structures of traditional coils and magnets, so that the volume of the sound production apparatus is smaller, and the sound production apparatus can be manufactured by the MEMS process.

Description

technical field [0001] The invention relates to the field of transducers, more precisely, the invention relates to a sound generating device; the invention also relates to a manufacturing method of the sound generating device. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment. As a transducer device that converts electrical signals into acoustic signals, it has been widely used in electronic products such as mobile phones and notebook computers. The existing loudspeaker module includes a casing, a vibration system and a magnetic circuit system arranged in the casing, wherein the vibration system includes a diaphragm and a voice coil arranged on the diaphragm for driving the diaphragm to sound, and the magnetic circuit system includes a magnet , Hua Si, etc. One end of the coil is connected to the diaphragm, and the other end extends into the magnetic gap of the magnetic circuit system. [0003] The structur...
