Open type sounder

Abstract

The invention discloses an open pronouncing device including, a magnetic steel with splint, a T-shaped soft iron core, a spring plate and a driving coil, in which, the driving pole is installed on the bottom of the coil, under which, a balance film maintaining the pronouncing device stable is fixed. The T-shaped soft iron core incases in the middle alnico and splint, which forms a certain slot. The connection of driving coil and spring plate fixes in the slot and can move reciprocating through electromagnetic effect. When getting through the driving current, the driving coil generates electromagnetic effect with iron core, alnico and splint, from which, kinetic energy will be conveyed by driving pole. If it is placed on any plane, kinetic energy will be transmitted to the plane and give out sound and cause surface resonate.

Description

technical field [0001] The invention relates to a sounding device. Background technique [0002] The loudspeakers widely used at present usually include magnetic steel and plywood, T-shaped soft iron core, voice coil, sound cone and sound cone stand, etc. Under the action of driving current, the voice coil generates electromagnetic effect with the magnetic gap composed of T-shaped soft iron core, magnetic steel and splint, and directly drives the sound cone to produce sound. This way of pronunciation is poor, in order to improve the effect, usually the speaker is installed in the cabinet, with the help of the cabinet to improve the pronunciation effect, the cabinet can be made of single or multiple materials, and has a variety of shapes and structures. Although the speaker composed of the speaker and the box can make the sound effect reach a relatively perfect level, there are many shortcomings, such as: 1. It is large in size and not easy to carry or move; 2. The sound eff...

This way of pronunciation is poor, in order to improve the effect, usually the speaker is installed in the cabinet, with the help of the cabinet to improve the pronunciation effect, the cabinet can be made of a single or multiple materials, and has a variety of shapes and structures

Although the speaker composed of the speaker and the box can make the sound effect reach a relatively perfect level, there are many shortcomings, such as: 1. It is large in size and not easy to carry or move; 2. The sound efficiency is low and there are obvious Directionality; 3. A large amount of materials are required and the process is very complicated; production, transportation and use require a large space, so the production and consumption costs are high
