Description
Technical field
The present invention relates to loudspeaker, particularly relate to a kind of electromagnetism for electrically driven (operated) loudspeaker.
Background technology
Loudspeaker are when AC audio electric current passes through the coil of loud speaker, so just create corresponding magnetic field in voice coil loudspeaker voice coil. the magnetic field that the permanent magnet that this magnetic field and loud speaker carry produces produces interaction force., this power just makes voice coil loudspeaker voice coil carrying in the magnetic field of permanent magnet along with tone currents vibration at loud speaker. and the vibrating diaphragm of loud speaker and voice coil loudspeaker voice coil connect together, so vibrating diaphragm also vibrates. and vibration just creates the sound identical with former audio signal waveform.
The material Nd-Fe-B permanent magnetic of what present loudspeaker used carry permanent magnet, main component is rear earth element nd (Re), iron (Fe), boron (B).Its rare earth elements is mainly neodymium (Nd).Because scarce resource uses because rare earth mining causes environmental destruction.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of non-magnet, do not use the electromagnetism of rare earth element for electrically driven (operated) loudspeaker.
The invention provides a kind of electromagnetism for electrically driven (operated) loudspeaker, comprise 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 comprises 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 a further improvement on the present invention, described support is T iron plastic rubber bracket, and described iron core is T iron.
As a further improvement on the present invention, described frame is plastic cement frame.
As a further improvement on the present invention, described frame is provided with groove, and described vibrating diaphragm portion comprises bullet 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 a further improvement on the present invention, described voice coil loudspeaker voice coil is arranged in described bullet ripple portion.
As a further improvement on the present invention, described cone is provided with outstanding edge, and described outstanding edge hangs over the top of described frame.
The invention has the beneficial effects as follows: 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, power source is added when giving magnetic induction loop two ends, iron core will produce magnetic field to replace permanent magnet, the generation polarity in magnetic field and the power in magnetic field can be followed and be adjusted according to requiring, thus facilitate designer's demand greatly, promote loudspeaker operating 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%, be convenient for carrying greatly, 0 magnetic field is accomplished in idle situation, salty few to ambient influence and interference, reduce scarce resource use because rare earth mining causes environmental destruction, reduction loudspeaker cost simultaneously, can only do the environmental protection really could accomplishing to respond country's proposition like this to call, let us work together protects the common home of the people of the world----the earth.
