Description
Technical field
The utility model relates to a kind of coil-moving speaker.
Background technology
Loud speaker is a kind of energy transducer signal of telecommunication being changed into acoustical signal, and the performance of loud speaker is good and bad very large on the impact of tonequality.Loud speaker is a device the weakest in stereo set, and for acoustics, it is again most important parts.Loud speaker of a great variety, and price differs greatly.Audio-frequency electric is by electromagnetism, and piezoelectricity or electrostatic effect, make its cone or diaphragm vibration and produce with ambient air resonate (sympathetic response) and sound.
Low-grade plastic loudspeaker box, because its casing is thin, cannot overcome resonance, can be sayed (also having the good plastic loudspeaker box of partial design will be better than wooden acoustic box inferior far away) without tonequality; Wood cabinet reduces the sound dye that casing resonance causes, and tonequality is generally better than plastic loudspeaker box.Usual multimedia loudspeaker box is all the design of two unit two divided-frequency, and alt output is responsible for by a less loud speaker, and the output of middle bass is responsible for by another larger loud speaker.
The voice unit of active multimedia loudspeaker boxes is existing based on soft ball top (having the titanium film ball top etc. for analog audio source in addition), and it matches with digital tone source and can reduce the stiff sense of high-frequency signal, gives tenderness, smooth, fine and smooth sensation.Existing in the majority with soft ball tops such as the good cortina of quality and lower-cost PV films of multimedia loudspeaker box.Bass unit which determines the feature of the sound of audio amplifier, selects relatively more important, modal have following several: cone, has again deposited gummed paper basin, paper substrate wool basin, to press basin processed etc. several.Cone tone color nature, cheap, rigidity, material are more highly sensitive preferably, but poor sealing can cause, and moisture resistance is poor, consistency is difficult to control when manufacturing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, long service life, and tonequality is good, highly sensitive coil-moving speaker.
For solving the problem, the utility model adopts following technical scheme:
A kind of coil-moving speaker, comprise shell, iron core, brandreth and cone, described iron core is established in the enclosure, described iron core arranged outside has permanent magnet, described permanent magnet is arranged ringwise, described permanent magnet glues together with iron core and is connected, described iron core side is connected with lead-in wire, described brandreth is located at permanent magnet side, arrange iron core to keep importing current stabilization, permanent magnet can provide constant magnetic field, holding structure is compact, easy for installation, long service life, voice coil suspension outside voice coil loudspeaker voice coil can keep voice coil vibrations to stablize, tonequality is good, highly sensitive, foam encasement can protect plate of speaking injury-free, described brandreth glues together with permanent magnet and is connected, described cone is located in brandreth, described cone one end is provided with voice coil loudspeaker voice coil, described voice coil loudspeaker voice coil arranged outside has voice coil suspension, described case nose is provided with plate of speaking, described plate of speaking is fixedly connected with shell, described plate arranged outside of speaking has foam encasement.
As preferably, described iron core is fixedly connected with shell, and holding structure is reliable and stable.
As preferably, described voice coil suspension is fixedly connected with brandreth, and holding structure is stablized.
As preferably, described in speak on plate and be provided with phonate hole, keep giving great volume.
As preferably, described phonate hole is provided with more than one, keeps audio good.
The beneficial effects of the utility model are: arrange iron core and keep importing current stabilization; permanent magnet can provide constant magnetic field; holding structure is compact; easy for installation; long service life, the voice coil suspension outside voice coil loudspeaker voice coil can keep voice coil vibrations to stablize, and tonequality is good; highly sensitive, foam encasement can protect plate of speaking injury-free.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of coil-moving speaker of the utility model.
Embodiment
As shown in Figure 1, a kind of coil-moving speaker, comprise shell 1, iron core 2, brandreth 3 and cone 4, described iron core 2 is located in shell 1, described iron core 2 arranged outside has permanent magnet 5, described permanent magnet 5 is arranged ringwise, described permanent magnet 5 glues together with iron core 2 and is connected, described iron core 2 side is connected with lead-in wire 6, in use, lead-in wire 6 enters power supply when making tone currents by voice coil loudspeaker voice coil 7 by iron core 2, the stationary magnetic field of the alternating magnetic field that voice coil loudspeaker voice coil 7 produces and permanent magnet 5 interacts and voice coil loudspeaker voice coil 7 is vibrated by audio frequency, drive cone 4 to promote air by voice coil loudspeaker voice coil 7 and sound, described brandreth 3 is located at permanent magnet 5 side, described brandreth 3 glues together with permanent magnet 5 and is connected, described cone 4 is located in brandreth 2, described cone 4 one end is provided with voice coil loudspeaker voice coil 7, described voice coil loudspeaker voice coil 7 arranged outside has voice coil suspension 8, described shell 1 front end is provided with plate 9 of speaking, described plate 9 of speaking is fixedly connected with shell 1, described plate 9 arranged outside of speaking has foam encasement 10.
Described iron core 2 is fixedly connected with shell 1, and in use, holding structure is reliable and stable.
Described voice coil suspension 8 is fixedly connected with brandreth 3, and in use, holding structure is stablized.
Described plate 9 of speaking is provided with phonate hole 11, in use, keeps giving great volume.
Described phonate hole 11 is provided with more than one, in use, keeps audio good.
In use, lead-in wire 6 enters power supply when making tone currents by voice coil loudspeaker voice coil 7 by iron core 2, the stationary magnetic field of the alternating magnetic field that voice coil loudspeaker voice coil 7 produces and permanent magnet 5 interacts and voice coil loudspeaker voice coil 7 is vibrated by audio frequency, drives cone 4 to promote air and sound by voice coil loudspeaker voice coil 7.
The beneficial effects of the utility model are: arrange iron core and keep importing current stabilization; permanent magnet can provide constant magnetic field; holding structure is compact; easy for installation; long service life, the voice coil suspension outside voice coil loudspeaker voice coil can keep voice coil vibrations to stablize, and tonequality is good; highly sensitive, foam encasement can protect plate of speaking injury-free.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in this with within novel protection range.
