Description

Technical Field

[0001] The utility model relates to the technical field of sound production, in particular to an integrated sound generating unit. Background Art

[0002] Most loudspeakers on the market generate sound by driving a diaphragm to vibrate through a coil (commonly known as moving coil), while another part of loudspeakers drive the diaphragm to generate sound through an iron sheet (commonly known as moving iron). The working principle of a moving coil is based on Faraday's law. When a current-carrying conductor passes through a magnetic field, it will receive an electromotive force, and its direction conforms to Fleming's left-hand rule. The force is perpendicular to the current and magnetic field directions, and the magnitude of the force is proportional to the current, wire length, and magnetic flux density. When an audio current of a pointer is input to the voice coil, the voice coil receives an alternating driving force to generate an alternating motion, driving the diaphragm to vibrate and repeatedly pushing the air to generate sound.

[0003] On a precision iron sheet of a moving iron, also called a balanced armature, it is in the center of a magnetic field and will vibrate under the action of the magnetic field of a permanent magnet. The vibration of this balanced armature is conducted to the center point of a micro diaphragm through a continuous rod with a precise structure, thereby generating sound. Currently, most headphone sound generating units use a single moving coil loudspeaker, and the sound generating effect is insufficient, and the sound is prone to defects, affecting the sound quality. Therefore, we propose an integrated sound generating unit to solve the above problems. Summary of the Utility Model
