Full-frequency band high quality electronic products speaker with a bar and sound tunnels

Abstract

A full-frequency band high quality electronic products speaker with a bar and sound tunnels, including a voice coil, metal plate, diaphragm and magnetically conductive structure; the diaphragm is annular, the outer edge combines with the speaker outer frame and the inner edge combines with the metal plate outer part; the diaphragm includes an annular bridge-type bar on the upper surface of the diaphragm inner edge, and located horizontally on the outside of the speaker metal plate; the diaphragm upper surface includes four grooves, which diaphragm surface outside the bridge-type bar is divided into four resonance regions; each groove crosses the bridge-type bar; and are concave on the diaphragm upper surface forming sound tunnels. The diaphragm changes to the standard vibration mode, and the timbre of treble register is not bright and the timbre of bass register is not sonorous and mellow enough from the perspective of vibration, resonance and phonation.
