Bilateral pronunciation type suspensible loudspeaker

Abstract

The invention discloses a bilateral pronunciation type suspensible loudspeaker, comprising a substrate, frames symmetrically arranged on both sides of the substrate, a sound production mechanism is respectively arranged in the frame on the sides, wherein a hook is arranged above the substrate, a supporting rod is fixed at the lower end of the hook, the lower end of the supporting rod penetrates through the substrate and extends to the lower side of the substrate, a plurality of fulcrum bars are uniformly distributed on the side wall below the substrate of the supporting rod along the circumferential direction of the supporting rod, the lower ends of the fulcrum bars are hinged with the supporting rod, the upper ends of the fulcrum bars are propped against the lower end face of the substrate, and an antiskid mechanism is arranged in the hook, and the sound production mechanism comprises a cone, a magnetic conducting plate, a driving magnet and a voice coil assembly used for driving the cone to vibrate. According to the bilateral pronunciation type suspensible loudspeaker provided by the invention, the error of the voice coil along the radial direction in a vibration sound production process of the voice coil is smaller, so that the sound production quality is better, meanwhile, the coverage of bilateral pronunciation is wide, and the bilateral pronunciation type suspensible loudspeaker is convenient to be arranged highly through the hook.

Description

technical field [0001] The invention relates to the technical field of electroacoustic transducers, in particular to a suspendable loudspeaker capable of sounding from both sides. Background technique [0002] The more conventional speaker is the dynamic speaker, also known as the dynamic speaker. Its working principle is based on Faraday's law. When a current-carrying conductor passes through a magnetic field, it will receive an electromotive force. Its direction conforms to Fleming's left-hand rule. The force, current, and magnetic field are perpendicular to each other. The magnetic flux density is directly proportional. 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 a...

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
