Abstract
The utility model provides a compound drive loudspeaker and relates to a loudspeaker. The compound drive loudspeaker comprises a magnet, a washer, a cone frame, a spider, a vibrating membrane and a dust cap, wherein the vibrating membrane is assembled together with the cone frame and a voice coil; and the spider and the voice coil are sealed in the cone frame by the vibrating membrane. The compound drive loudspeaker further comprises an iron core seat and an electromagnetic coil; the iron core seat comprises an integrally-built seat board and a post core vertical to the seat board; the post core is positioned at the geometric centre position of the seat board; one end of the post core and the seat board are connected into a whole, and the other end of the post core is a free end and is T-shaped; the electromagnetic coil is wound on the post core; a magnet is arranged at the periphery of the electromagnetic coil. The sound production efficiency of the loudspeaker is improved; by virtue of combining the intercommunity of an electromagnet and a traditional magnetic path, the magnetic force of the electromagnet and the magnetic force of a traditional magnetic return path are mutually superposed, so that the loudspeaker can realize the enhancement of magnetic energy under the condition of not changing external dimensions, the dependence on high-performance magnetic materials is omitted, the product cost is controlled, and the sensitivity of the loudspeaker is improved.
Description
Technical field
The utility model relates to loud speaker, refers to a kind of combination flooding dynamic formula loud speaker especially.
Background technology
Because the cost increase of high-performance magnetism material is too fast; Use originally that the speaker product of high-performance magnetic material is all compelled to have gained traditional Ferrite; Thereby the acoustic performance of product and phonation efficiency are had a greatly reduced quality; Product height also has to increase. and this makes most of clients worried for it. and therefore, how to make the product of conventional permanent magnet magnetic loop design improve acoustic performance and phonation efficiency, can also not increase the primary research and development task that product height is each tame loudspeaker design and manufacturing enterprise simultaneously.Use minimum cost because have only, obtaining maximum benefit is that each client is desirable.In order to strive for the client, promote the enterprise product technological competitiveness.So just need on traditional magnetic circuit structure for loudspeaker, do some transformations, and this also is a technical barrier.
Summary of the invention
In order to overcome the deficiency that traditional magnetic loop structure magnetic energy intensity exists, the utility model provides a kind of combination flooding dynamic formula loud speaker, and it has the characteristics of compound driving.
For this reason, the technical scheme of the utility model employing is following:
A kind of combination flooding dynamic formula of structure the utility model loud speaker; Comprise magnet, washer, basin frame, play ripple, voice coil loudspeaker voice coil, vibrating diaphragm and dust cap; Vibrating diaphragm and basin frame and voice coil loudspeaker voice coil are equipped, and vibrating diaphragm involves voice coil loudspeaker voice coil to bullet and is enclosed in the basin frame, also comprises an irony core print seat and a solenoid; Said irony core print seat comprises becomes integrally-built seat board and the post core vertical with seat board; Said post core is positioned at the geometric center position of seat board, and an end of said post core and said seat board structure connect and be that integral body, the other end of said post core are free end and are " T " shape; Solenoid is wound in said post core, at the peripheral distributed magnet of solenoid, direct voltage is imported solenoid to produce magnetic field and superimposed with the magnetic field of magnet; The free end of said post core puts in the wherein end of voice coil loudspeaker voice coil; Equipped washer on magnet, basin frame and washer install.
Technique scheme is further set forth:
Said basin frame is a rectangle, or circular, or oval.
The outer end of basin frame is provided with an audio signal input end daughter board, and this terminal board is connected to the voice coil loudspeaker voice coil in the basin frame through lead.
Solenoid directly is connected with direct current through connecting line.
The mechanism of the utility model is: through the design of said irony core print seat; Solenoid is wound in said post core, forms electromagnet, produces electromagnetic force; The magnetic force mutual superposition that electromagnetic force and said magnet are produced; Form a kind of compound Drive Structure, thereby reach the function that improves traditional magnetic loop magnetic force, to realize increasing speaker drive power.Simultaneously, solenoid is closed in the inside of traditional magnetic loop, thereby the electromagnetic force of generation passes to the magnetic gap of washer and the formation of post core through the post core. strengthened the magnetic intensity in the magnetic gap.
The beneficial effect of the utility model is: this NEW TYPE OF COMPOSITE Drive Structure design has promoted the phonation efficiency of loud speaker greatly; Through combining the intercommunity of electromagnet and traditional magnetic circuit, make electromagnet magnetic force and traditional magnetic loop magnetic force mutual superposition, the sensitivity that has improved loud speaker; Make loud speaker under the condition of change outer size not, realize the enhancing of magnetic energy.Save the target that relies on the high-performance magnetic material design simultaneously, controlled product cost.
