Hangable dynamic speaker

Abstract

The invention discloses a suspensible moving coil type loudspeaker comprising a cone stand, a paper cone, a first magnetic conductive plate, a second magnetic conductive plate, a driving magnet and a voice coil component which is used for driving the paper cone to vibrate. The suspensible moving coil type loudspeaker is characterized in that the first magnetic conductive plate is provided with a circular arc-shaped hook which is connected with the first magnetic conductive plate via a straight rod. The hook is internally provided with an anti-sliding mechanism. The voice coil component comprises a center guiding sleeve, at least two magnetic conductive core columns and voice coils which are wound on the external side wall of each magnetic conductive core column. According to the suspensible moving coil type loudspeaker, radial deviation of the voice coils is low in the vibrating and sound generating process of the voice coils so that the generated sound quality is great. Besides, the paper cone can be replaced by a user when the paper cone is damaged without discarding the whole loudspeaker.

Description

Technical field [0001] The invention relates to the technical field of electro-acoustic transducer devices, in particular to a suspensionable moving coil speaker. Background technique [0002] Moving coil speakers are also called electrodynamic speakers. 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 is perpendicular to the current and the magnetic field. The force is proportional to the current, wire length, The magnetic flux density is proportional. When the voice coil inputs an 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 push the air to produce sound. In the process of voice coil vibration, reducing the deviation of the voice coil in the radial direction is an important indicator t...

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

[0004] In addition, since the paper cone of the speaker is a part directly exposed to the external environment, it is more likely to be damaged by external forces during the user's use. With the damage of the paper cone, the entire speaker cannot be used normally and can only be scrapped. processing, thus causing a large waste

Certainly, the speakers in the prior art can also be repaired by professional maintenance personnel when the paper cone is damaged, but the repair process not only requires high labor costs, but also is relatively complicated.

Even the cost of maintenance is higher than the price of new loudspeakers, so when users encounter such problems in the prior art, they often adopt scrapping, which causes a lot of waste
