See full text

A full-frequency band high quality speaker with a bar and sound tunnels includes a voice coil, magnet, diaphragm and magnetically conductive structure; the diaphragm is conical, a bridge-style bar is on the surface of at least one side of the diaphragm; the diaphragm includes at least two grooves, each horizontally radial; each groove crosses the bridge-type bar in the horizontal direction and the length direction of the groove is perpendicular to the bridge-type bar; the groove is concave on the surface of the diaphragm to form a sound tunnel. The diaphragm is changed to the current 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. The practice proves that the improved scheme has outstanding substantive characteristics and remarkable technical progress, and has obtained obvious technical results.
