Hanging double-sided sounding horn

Abstract

The invention discloses a suspended two-side sound production speaker. The suspended two-side sound production speaker comprises a substrate, and two frames symmetrically arranged on the two sides of the substrate; a sound production mechanism is arranged in the frame on each side; the suspended two-side sound production speaker is characterized in that a hoop is arranged above the substrate, a strut is fixed on the lower end of the hook and the lower end of the strut penetrates through the substrate and extends under the substrate; a plurality of supporting rods are evenly distributed on the sidewall of the strut under the substrate in the circumferential direction of the strut; the lower ends of the supporting rods are hinged to the strut, while the upper ends of the supporting rods prop against the lower end face of the substrate; an anti-slipping mechanism is arranged in the hook; the sound production mechanism comprises a cone, a concentrating flux plate, a driving magnet, a concentrating flux core column, a voice coil and a voice coil guiding cylinder; a lubrication mechanism is arranged between the concentrating flux core column and the voice coil guiding cylinder. The suspended two-side sound production speaker has the advantages of small deviation of the voice coil in the radial direction in the vibrating sound production process of the voice coil, good produced sound quality and wide coverage, and can be arranged at a high position conveniently.

Description

technical field [0001] The invention relates to the technical field of electroacoustic transducers, in particular to a suspended double-sided sounding horn. Background technique [0002] The horn is also called the loudspeaker. Its working principle is based on Faraday's law. When the current-carrying conductor passes through the magnetic field, it will receive an electromotive force, and its direction conforms to Fleming's left-hand rule. Proportional to current, wire length, and magnetic flux density. When the voice coil is input with alternating audio current, the voice coil is subjected to an alternating driving force to produce alternating motion, which drives the paper cone to vibrate, and repeatedly pushes the air to produce sound. In the vibration process of the voice coil, reducing the deviation of the voice coil along the radial direction is an important index to ensure the sound quality. [0003] However, in the prior art electric speakers, the voice coil is oft...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art electric speakers, the voice coil is often directly accommodated in the central hole of the driving magnet, or the voice coil is placed outside a columnar magnetic core, and in order to reduce the friction between the voice coil and the magnet , therefore, there must be a large sliding gap between the voice coil and the magnet

This leads to a large radial deviation of the voice coil in the process of vibrating and sounding, resulting in misalignment of the sound
