Document Type and Number:
WIPO Patent Application WO/2022/036959
Kind Code:
A1
Abstract:
A 360-degree omni-directional full frequency loudspeaker and a vibrating diaphragm thereof. The loudspeaker comprises a lantern-shaped diaphragm, which is mainly composed by a group of vibrating diaphragms being uniformly arranged around the central axis of the lantern shape. The main body of the vibrating diaphragm is a curved sheet body, which is characterized in that a double sound beam is fixed in parallel on an inner recessed surface of the sheet body, while a transverse groove and a longitudinal groove are provided on the inner recessed surface of the sheet body, and the transverse groove and the longitudinal groove are arranged in a cross and linked to one another on the inner recessed surface of the sheet body and form a cross-shaped sound tunnel. The present solution solves the problem in which original 360-degree omni-directional speakers are not suitable for full frequency (broadband) vibration. Now, a 360-degree omni-directional full frequency speaker can replace the original combination of high, medium, and low tone 360 degree omni-directional speakers, and at the same time can even replace the effect obtained by a subwoofer.
