Abstract
The invention discloses a full-frequency loudspeaker provided with double voice coils, which comprises a loudspeaker bracket, a loudspeaker diaphragm, a dustproof cap, a spring wave, the voice coils, a magnetic circuit structure and a base bracket, wherein the loudspeaker diaphragm, the dustproof cap and the spring wave are installed on the loudspeaker bracket; the voice coils are used for driving the diaphragm to vibrate; the loudspeaker bracket and the magnetic circuit structure are installed on the base bracket; the two voice coils comprise a voice coil I and a voice coil II which are wound along the reverse direction; the magnetic circuit structure is a radial magnetic circuit structure which comprises a magnetic conductor and a permanent magnet; the magnetic conductor takes on a ring shape and is provided with a ring-shaped groove in the middle; and the permanent magnet takes on a ring shape and is arranged in the ring-shaped groove of the magnetic conductor in a suspension way.
Description
Technical field
The present invention relates to a kind of loud speaker.
Background technology
In the design of full range speaker, because the common horizontal magnetic circuit that adopts is the tonequality that single-tone circle or double-tone circle all can influence loud speaker because of the magnetic conduction problem.
Summary of the invention
Problem to be solved by this invention provide a kind of can bigger lifting loud speaker efficient and the full frequency speaker of the double-tone circle of tonequality.
The technical solution adopted in the present invention is: the full frequency speaker of double-tone circle comprises loudspeaker support, the diaphragm of loudspeaker, dust cap, play ripple, voice coil loudspeaker voice coil, magnetic structure and base support, the described diaphragm of loudspeaker, dust cap, playing ripple is installed on the loudspeaker support, described voice coil loudspeaker voice coil drives the vibrating diaphragm vibration, described loudspeaker support, magnetic structure is installed on the base support, described voice coil loudspeaker voice coil comprises voice coil loudspeaker voice coil one and 2 two voice coil loudspeaker voice coils of voice coil loudspeaker voice coil, voice coil loudspeaker voice coil one and voice coil loudspeaker voice coil two reverse coilings, described magnetic structure is magnetic structure radially, described radially magnetic structure comprises magnetic conductor, permanent magnet, described magnetic conductor in the form of a ring, the centre has a cannelure, described permanent magnet is suspended in the cannelure of magnetic conductor in the form of a ring.
In the such scheme, magnetic conductor also can be circular or the cross section also can be the ring-type of other regular polygons.
The invention has the beneficial effects as follows: the present invention is owing to formed two magnetic gaps in the magnetic circuit, two magnetic gaps transient response ability that makes loud speaker that interacts is greatly improved, two magnetic closures that voice coil loudspeaker voice coil forms, stopped because the distortion that leakage field produces, can be widely used in high-quality speaker design, efficient that can bigger lifting loud speaker, and avoid owing to cut apart the distortion that vibration produces.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1, the full frequency speaker of double-tone circle comprises loudspeaker support 1, the diaphragm of loudspeaker 2, dust cap 3, play ripple 4, voice coil loudspeaker voice coil 1, voice coil loudspeaker voice coil 26, magnetic structure and base support 7, the diaphragm of loudspeaker 2, dust cap 3, playing ripple 4 is installed on the loudspeaker support 1, voice coil loudspeaker voice coil 1 and voice coil loudspeaker voice coil 26 reverse coilings, drive same vibrating diaphragm 2 vibrations simultaneously, therefore two voice coil loudspeaker voice coils need not the frequency division processing in power amplifier electricity network, loudspeaker support 1, magnetic structure is installed on the base support 7, magnetic structure is magnetic structure radially, radially magnetic structure comprises magnetic conductor 8, permanent magnet 9, magnetic conductor 8 in the form of a ring, the centre has a cannelure 10, permanent magnet 9 in the form of a ring, be suspended in the cannelure 10 of magnetic conductor 8, owing to adopt same radially magnetic circuit, form two magnetic gaps in the magnetic conductor 8, voice coil loudspeaker voice coil 1 and voice coil loudspeaker voice coil 26 reverse coilings, induction thus, make electromagnetic field strengthen (similar) mutually in the transformer effect, and produce more powerful driving effect thus, be greatly improved owing to formed two magnetic gaps transient response ability that makes loud speaker that interacts in the magnetic circuit, two magnetic closures that voice coil loudspeaker voice coil forms have been stopped because the distortion that leakage field produces and owing to cut apart the distortion that vibration produces.
Claims (2)
