Abstract
The utility model provides a moving-coil speaker using combined vibration film which is characterized in that a big sound coil is arranged at the edge of the big vibration film which is arranged in the speaker, and arranged in the magnetic circuit system which is arranged in the middle of the basin holder; a small sound coil is arranged at the centre of the small vibration film, and arranged in the magnetic circuit system which is arranged at the bottom of the basin holder; the small vibration film is conglutinated at the edge of the opening of the inner ring of the big vibration film. When the tone current gets across and connected in parallel with the two sound coils, the reciprocity between the magnetic fields makes the two vibration film sound at the same time; because the small vibration film is capable of vibrating independently, effectively increasing the playback bandwidth of the speaker, reducing distortion and increasing power.
Description
The utility model relates to a kind of variation tone currents and converts mechanical oscillation to and the coil-moving speaker of sounding, particularly a kind of conversion efficiency height, and the playback bandwidth, audio distortions is little, adopts the loud speaker of composite type vibrating diaphragm.Be suitable for various tone currentss are converted to mechanical oscillation, and the promotion air is sounded.
Existing coil-moving speaker is by vibrating diaphragm, and voice coil loudspeaker voice coil, magnetic circuit system are formed, magnetic field and the magnetic field interaction in the magnetic circuit system that tone currents produces during by voice coil loudspeaker voice coil, and drive vibrating diaphragm vibration sounding.Voice coil loudspeaker voice coil in the existing loud speaker is installed in single vibrating diaphragm center, the efficient difference the when vibrating diaphragm of certain area is operated in various frequency, and single vibrating diaphragm makes the playback frequency bandwidth be subjected to certain placing restrictions on, and frequency distortion strengthens.Because voice coil loudspeaker voice coil and vibrating diaphragm edge have distance, the vibrating diaphragm operating efficiency reduces during low frequency.Therefore to improving the conversion efficiency of loud speaker, increase the playback frequency bandwidth, reduce distortion and all can't effectively be implemented.
Task of the present utility model provides a kind of coil-moving speaker that adopts the composite type vibrating diaphragm, and it can improve conversion efficiency effectively.Increase the playback frequency bandwidth, reduce distortion, and increased the power of loud speaker.
Task of the present utility model is finished as follows: the good film edge in the loud speaker has ring, and the outer ring is bonded on the basin frame forward edge, and the ring inner ring is installed big voice coil loudspeaker voice coil, and big voice coil loudspeaker voice coil is in the magnetic circuit system that is installed in basin frame middle part.Little vibrating diaphragm edge also has ring, and the outer ring is bonded on the edge of big vibrating diaphragm inner ring tapping, and little voice coil loudspeaker voice coil is installed at the center, and little voice coil loudspeaker voice coil is in the magnetic circuit system that is installed in basin frame bottom, and two voice coil loudspeaker voice coil same-phases are connected in parallel.Magnetic field interaction in magnetic field that tone currents produces during by voice coil loudspeaker voice coil and magnetic circuit system, and drive big or small vibrating diaphragm vibration sounding.Because little vibrating diaphragm has ring and voice coil loudspeaker voice coil independently, can also independently vibrate during with big vibrating diaphragm co-operation, improve the operating efficiency of vibrating diaphragm when various frequency significantly, increased power, and the minimizing distortion.When the exemplary construction that will describe in detail below adopting, the coil-moving speaker of composite type vibrating diaphragm is simple in structure, the playback bandwidth, and the conversion efficiency height has certain economic benefit.
Below with reference to accompanying drawing the utility model is made into detailed description.
Accompanying drawing is a kind of concrete structure figure of the present utility model.
With reference to accompanying drawing: big vibrating diaphragm (2) edge has ring (1), the outer ring is bonded on the anterior edge of basin frame (5), ring (1) inner ring is installed by copper cash (21) and is wound on big voice coil loudspeaker voice coil (6) on the skeleton (20), and the skeleton surface has several holes (7), and voice coil loudspeaker voice coil weight is reduced.The big deckle board (8) of soft iron permeability magnetic material, T shape open tubular column (10), big magnet (9) formation of the annular magnetic circuit system with the hard iron magnetic material is installed in basin frame (5) middle part.Copper coil (21) is in the magnetic gap of magnetic circuit system.The big support (13) that is installed in basin frame (5) afterbody joins through connected set (11) and big vibrating diaphragm (2).Support has certain elasticity, plays positioning action.Little vibrating diaphragm (4) edge has ring (3), and the outer ring is bonded on the inner ring tapping edge of big vibrating diaphragm (2), and the center is installed by copper cash (18) and is wound on little voice coil loudspeaker voice coil (14) on the little skeleton (19).Little deckle board (15), T shape solid post (17), annular small magnet (16) constitutes the one magnetic path system, is installed in basin frame (5) bottom.Copper coil (18) is in the magnetic gap of this magnetic circuit system.The small rack (12) that is installed in little voice coil loudspeaker voice coil (14) middle part joins with connected set (11) inner ring.Two copper coils (18), (21) same-phase are connected in parallel.
When tone currents passes through two copper coils (18), (21), two vibrating diaphragms (2), the vibration of (4) same-phase, loud speaker is started working.When audio frequency is low, mainly by big vibrating diaphragm (2) vibration sounding.When frequency is higher, mainly, increased the playback frequency bandwidth significantly, reduced distortion, and improved power of loudspeaker by little vibrating diaphragm (4) vibration sounding.The voice coil loudspeaker voice coil (6) that increases diameter increases with big vibrating diaphragm (2) faying face, advances the operating efficiency of a loud speaker when having improved low frequency.Being in the vibrating diaphragm back is hollow T shape post (10), air can be circulated and does not influence the vibrating diaphragm sounding.
