Description
Technical Field
The invention mainly relates to an electromagnetic vibration device, in particular to a vibration device which utilizes two vibration plate modules to be oppositely buckled and fixed, or adopts upper and lower suspension edges to be oppositely and respectively connected and fixed on the upper and lower surfaces of a vibration plate and a base; the vibrating plate device and the manufacturing method thereof replace the traditional elastic wave function.
Background
As is well known, an electromagnetic vibrator, also called a speaker, commonly known as a "horn", is an electroacoustic device that converts electrical energy into acoustic energy. The manufacturing process of the traditional loudspeaker comprises the steps of adhering T iron or U iron, adhering a basin frame and a magnetic return, installing a terminal, releasing elastic waves, inserting a voice coil, releasing a drum paper hanging edge and the like; firstly, preparing required materials, and manually manufacturing from inside to outside from bottom to top; the elastic wave is also called centering support, is another main element in the vibration system of the cone loudspeaker, is a corrugated ring which is formed by impregnating materials such as cotton cloth, silk cloth, glass cloth and the like with phenolic resin and then performing hot pressing, and has the main functions of:
(1) the voice coil is required to be large in axial compliance by keeping the correct position of the voice coil in the magnetic gap, so that the voice coil can vertically vibrate in the magnetic gap, and the voice coil is required to reliably limit the left and right movement of the voice coil in the radial direction so that the voice coil is not contacted with a washer and a T iron;
(2) the support provides a restoring force to the loudspeaker and influences the mechanical Q value of the loudspeaker, namely the damping characteristic;
(3) the resonance frequency of the loudspeaker is determined by the elastic wave, the cone and the voice coil;
(4) the damper of the compound side loudspeaker plays the role of a buffer and a mechanical amplitude limiter;
based on the above function of the damper, in the conventional speaker, the inner ring of the damper is connected and fixed to the voice coil, and the outer ring surface of the damper needs to be connected and fixed to the base frame of the speaker, thereby limiting the thinness of the speaker.
However, with the development of society, the living standard of people is continuously improved, and the requirements on electronic products such as liquid crystal televisions, notebook computers, mobile phones and the like are thin, and meanwhile, the sound quality of the electronic products is emphasized; referring to fig. 1, the thickness of a conventional speaker, which is used in these electronic products and is limited by the influence of the structure of the conventional speaker (most commonly, cone-shaped and arc-shaped vibration drum paper is adhered to and soaked by resin fiber elastic waves), maintains a stroke of back and forth movement, and is adhered to a voice coil by using the conventional circular ring-shaped elastic waves, the voice coil is adhered to the conventional drum paper, and the drum paper is adhered to a suspension edge. The inner connection surface of the elastic wave fixes the voice coil at the central position of the magnetic return system by a glue applying mode, and the outer connection surface of the elastic wave is also fixed on the base frame of the loudspeaker by a glue applying mode; the inner edge of the vibration drum paper of the loudspeaker is also fixed by a gluing mode and a voice coil, and the outer edge of the vibration drum paper is fixedly arranged on the base frame on the loudspeaker by gluing through a suspended edge; the whole loudspeaker is supported and fixed by the elastic waves and the suspension edges to form a suspension system of the whole loudspeaker; therefore, because the traditional vibrating drum paper, the suspension edge and the traditional damper structure inevitably affect that the loudspeaker structure cannot be thinned, when the whole loudspeaker moves up and down, the whole loudspeaker moves along the motion axis of the suspension edge and the damper, the suspension edge and the damper are fixed on a loudspeaker basin frame (a base frame), the position of the suspension edge and the damper is positioned at the upper edge of the top surface of the base frame, and the damper is positioned at the bottom of the base frame; meanwhile, the application of the traditional elastic wave limits the thickness of the loudspeaker, and the requirements of electronic products on the loudspeaker cannot be met; moreover, over a long period of time, the glue can age or even come unstuck, which can cause the tone quality of the loudspeaker to change or the whole loudspeaker to be scrapped.
Furthermore, some passive radiation type sound boxes on the market at present have two speakers in appearance, one speaker is only fake actually because the speaker cannot work independently, only one suspension edge and one vibrating plate are fixed on the box body of the sound box, the speaker is only an auxiliary vibrator actually, and the sound wave generated when one speaker works is utilized to drive the speaker to work, so that a better sound quality effect is achieved. In addition, the auxiliary vibrator has only one suspended edge to fix the vibrating plate, so that the stroke of the vibrating plate is unbalanced easily, noise is generated, and the sound quality effect of the vibrating plate is influenced.
