Three-dimensional wave coaxial motor-driven loudspeaker

Abstract

The invention relates to a loudspeaker, in particular to a three-dimensional wave coaxial motor-driven loudspeaker. The three-dimensional wave coaxial motor-driven loudspeaker comprises a voice coil set, vibrating diaphragms, a cylinder, a cone support, a locating support and a spiral rubber pipe wire. The three-dimensional coaxial motor-driven loudspeaker is characterized in that the voice coil set is formed by m voice coils in same structure, the m vibrating diaphragms are same in structure, the m vibrating diaphragms and the voice coil set are coaxial and synchronous, and the m vibrating diaphragms are coaxial with the sound basin support; the cylinder is jointly and coaxially formed by a screw, n magnets, m separating sheets or I-shaped sleeves and nuts; the cylinder is respectively fixed on the sound basin support and the locating support, and the sound basin support, the locating support and the cylinder are concentric and coaxial with the vibrating diaphragms; a voice coil set lead is the spiral rubber pipe wire; the n is larger than or equal to three, and the m is larger than or equal to two. The three-dimensional coaxial motor-driven loudspeaker has the advantages of being high in sensitivity, high in fidelity factor, high in electricity-sound conversion efficiency and low in requirement for power amplification. Frequency response fidelity at 20 Hz-20 KHz is guaranteed, and the convention that the loudspeaker is not used in a music hall will be broken.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a stereo wave electric loudspeaker. Background technique [0002] Stereo wave speakers are electric speakers that always emit sound (sound) waves of the same fixed thickness synchronously. [0003] Although stereo sound only adds a pickup when recording, and adds a set of playback units during playback, the auditory time difference will form a three-dimensional sound field that seems to be in the virtual space of the scene. However, the sound wave at each instant is still a two-dimensional surface sound wave. Stereo wave is a sound wave / sound wave formed by a certain thickness / mass body of air generated when 2 to m diaphragms with fixed intervals, coaxial or same body, and synchronous vibration are driven by audio current. In short, it is a three-dimensional sound wave / sound wave generated by the fixed volume of air between the front and rear cones following the vibration of the diaphragm drive...

AI Technical Summary

Problems solved by technology

[0005] Existing coaxial loudspeakers have the following technical defects: 1. The ubiquitous defects of narrow sound diffusion surface resolution and poor layering, especially the high frequency part is limited by the size of the magnet and the sound field is narrow and uneven

3. Existing coaxial speakers are only coaxial in shape: ① mechanical superposition, large size disparity, the sound field of small speakers is submerged by large speakers

[0008] To sum up, the existing electric loudspeakers are not ideal for "live sound" facsimile and playback due to the defects and characteristics brought about by their structure and principle.
