Description
Technical field
This utility model relates to loudspeaker, particularly relates to a kind of electromagnetism for electrically driven (operated) loudspeaker.
Background technology
Loudspeaker are when AC audio electric current is by the coil of speaker, voice coil loudspeaker voice coil just creates corresponding magnetic field. the magnetic field that the permanent magnet carried on this magnetic field and speaker produces produces interaction force. then, this power just makes voice coil loudspeaker voice coil in the magnetic field carrying permanent magnet of speaker along with tone currents vibrates. and the vibrating diaphragm of speaker and voice coil loudspeaker voice coil connect together, so vibrating diaphragm also vibrates. vibration just creates the sound identical with former audio signal waveform.
What present loudspeaker used carries the material Nd-Fe-B permanent magnetic of permanent magnet, is mainly composed of rear earth element nd (Re), ferrum (Fe), boron (B). Its rare earth elements is mainly neodymium (Nd). Owing to scarce resource uses because rare earth mining causes environmental destruction.
Summary of the invention
In order to solve the problems of the prior art, electromagnetism that this utility model provides a kind of non-magnet, that do not use rare earth element is for electrically driven (operated) loudspeaker.
This utility model provides a kind of electromagnetism for electrically driven (operated) loudspeaker, including frame, magnetic field generation section, voice coil loudspeaker voice coil and vibrating diaphragm portion, wherein, described magnetic field generation section is connected with the bottom of described frame, described voice coil loudspeaker voice coil, diaphragm portion are not arranged in described frame, and described magnetic field generation section is electromagnetic drive part, and described electromagnetic drive part includes support, iron core and magnetic induction loop, described iron core is arranged on the bracket, and described magnetic induction loop is enclosed within described iron core.
As further improvement of the utility model, described support is T ferrum plastic rubber bracket, and described iron core is T ferrum.
As further improvement of the utility model, described frame is plastic cement frame.
As further improvement of the utility model, described frame is provided with groove, and described vibrating diaphragm portion includes playing ripple portion, cone and dust cap, and described bullet ripple portion is arranged in the groove of described frame, described cone hangs in the groove of described frame, and described dust cap is arranged on described cone.
As further improvement of the utility model, described voice coil loudspeaker voice coil is arranged in described bullet ripple portion.
As further improvement of the utility model, described cone is provided with outstanding edge, and described outstanding edge hangs over the top of described frame.
The beneficial effects of the utility model are: use support, the electromagnetic drive part that iron core and magnetic induction loop are formed replaces permanent magnet, around upper magnetic induction loop on the iron core (also known as conducting magnetic column) at voice coil loudspeaker voice coil center, when adding power source to magnetic induction loop two ends, iron core will produce magnetic field to replace permanent magnet, the power of the polarity and magnetic field that produce magnetic field can with according to requiring to adjust, thus greatly facilitating designer's demand, promote loudspeaker work efficiency, add the stroke that typhon moves up and down simultaneously, promote the sensitivity of loudspeaker, the sound sent is more perfect, overall weight saving 20-50%, greatly it is convenient for carrying, 0 magnetic field is accomplished in idle situation, salty few to ambient influence and interference, reduce and scarce resource is used and because rare earth mining causes environmental destruction, reduces loudspeaker cost simultaneously, do so just can only being truly realized the environmental protection call that response country proposes, let us work together protects the home that the people of the world is common----the earth.
