Description
[technical field]
The utility model relates to the technical field of stereo set, particularly a kind of technical field of echoless pure tone steady magnetic field Music centre loudspeaker.
[background technology]
The sound that Music centre loudspeaker sends is changed by the signal of telecommunication, the principle of sound of Music centre loudspeaker utilizes the change by the tone currents of coil, the electromagnetic field that coil produces is different, changing of electromagnetic field and magnetic fields, the vibrations of sound film are driven by coil, also cause sound basin to vibrate simultaneously, these actions make the density degree of air change and produce sound, sound can be amplified, the range of application of Music centre loudspeaker is relatively more extensive, and such as meeting room, the great hall and some public places all need to use Music centre loudspeaker.Classify in drive principle mode, Music centre loudspeaker can be divided into moving-coil type, electrostatic, piezo-electric type.At present, range is wide, low cost and other advantages owing to having for moving-coil type Music centre loudspeaker, and its application is the most universal.Along with the raising of people's living standard, the requirement of people to tonequality is more and more higher, moving-coil type Music centre loudspeaker generally includes sound film, voice coil loudspeaker voice coil, magnet and circuit board, when tone currents is from circuit board flowing through voice coil, voice coil loudspeaker voice coil moves accordingly repeatedly by the magnetic field force effect generation of magnet, thus drive sound film to produce piston type vibration, and then promote ambient air generation sound, but having different timbres of sending of the sound that sends due to the member reflects such as reel or vibrations of traditional Music centre loudspeaker and sound film, so sound is pure not, how can to reduce in Music centre loudspeaker some sound sent because of reflection or shake and the different phenomenon of sound film occurs, it is one of technological means improving Music centre loudspeaker tonequality.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, propose a kind of echoless pure tone steady magnetic field Music centre loudspeaker, can reduce the part sounding that sounding and sound film tone color in Music centre loudspeaker are inconsistent, Music centre loudspeaker sounding noise is little, sound is purer, and structure is simple simultaneously.
For achieving the above object, the utility model proposes a kind of echoless pure tone steady magnetic field Music centre loudspeaker, comprise T iron, sealing ring, frame, coil, drum paper, play ripple, magnet ring and coil around cylinder, on described T iron, cover has magnet ring, the right side of described magnet ring is provided with top iron and screw, described top iron and screw is installed with disc, frame is fixedly connected with on the right side of described disc, on cylinder on T iron, cover has coil around cylinder, described coil is wound with coil on cylinder, cylinder on T iron is fixedly pasted with noise reduction body, frame is provided with bulging paper, on the left of described bulging paper, be provided with bullet ripple.
As preferably, on described magnet ring, cover has sealing ring, and the both sides of described sealing ring contact with top iron and screw with T iron respectively.
As preferably, the right side of described noise reduction body is provided with sound wave diffusingsurface, and described sound wave diffusingsurface is taper.
As preferably, be provided with holder on the left of described noise reduction body, described holder is fixedly pasted onto on the cylinder end face on T iron.
The beneficial effects of the utility model: the utility model is by being applied in Music centre loudspeaker by noise reduction body, the shape special by noise reduction body and material, sound reflection can be reduced, simultaneously can by sound reflection to sidepiece, the sounding purity of sound equipment can be improved, reduce noise, device structure is simpler simultaneously.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
