Abstract
The utility model discloses a kind of two film earphone horn, comprise circular shell, magnet, washer, voice coil loudspeaker voice coil, the first vibrating diaphragm, the second vibrating diaphragm, dust cap, lower cover, the first bullet ripple, the second bullet ripple; Wherein magnet is fixed on down and covers, and described voice coil loudspeaker voice coil is enclosed within outside described magnet; On the first vibrating diaphragm above the upper end of described voice coil loudspeaker voice coil is fixed on and is positioned at, on the second vibrating diaphragm below the other end is fixed on and is positioned at; Described dust cap is located at the top of described voice coil loudspeaker voice coil, and described first plays ripple is connected between described voice coil loudspeaker voice coil upper end and described shell, and described second plays ripple is connected between described voice coil loudspeaker voice coil lower end and described shell.Adopt technique scheme, of the present utility model pair of film earphone horn, when after voice coil loudspeaker voice coil energising, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces can along with changing, active force is produced, Continuous Drive first vibrating diaphragm, the second vibrating diaphragm vibrations sounding with magnet.
Description
Technical field
The utility model relates to earphone field, particularly relates to a kind of two film earphone horn.
Background technology
Earphone is a kind of electronic product conventional in life.As shown in Figure 1, the loudspeaker of earphone generally include frame 101, base 102, iron core 103, magnet 104, voice coil loudspeaker voice coil 105, vibrating diaphragm 106, dust cap 107 and play ripple 108.After voice coil loudspeaker voice coil 105 is energized, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces along with changing, can produce active force with magnet 104, and Continuous Drive vibrating diaphragm 106 shakes sounding.
Earphone horn of the prior art is all only arrange a vibrating diaphragm in one direction, and therefore sound can only be propagated to a direction, is necessary to relate to a kind of new earphone horn, can propagates to both direction.
Utility model content
Therefore, the technical problems to be solved in the utility model is to provide a kind of two film earphone horns can propagated to both direction.
To achieve these goals, the two film earphone horn of one of the present utility model, comprises circular shell, magnet, washer, voice coil loudspeaker voice coil, the first vibrating diaphragm, the second vibrating diaphragm, dust cap, lower cover, the first bullet ripple, the second bullet ripple; Wherein magnet is fixed on down and covers, and described voice coil loudspeaker voice coil is enclosed within outside described magnet; On the first vibrating diaphragm above the upper end of described voice coil loudspeaker voice coil is fixed on and is positioned at, on the second vibrating diaphragm below the other end is fixed on and is positioned at; Described dust cap is located at the top of described voice coil loudspeaker voice coil, and described first plays ripple is connected between described voice coil loudspeaker voice coil upper end and described shell, and described second plays ripple is connected between described voice coil loudspeaker voice coil lower end and described shell.
Described lower cover comprises the outer toroid and interior annulus that arrange with one heart, between described outer toroid and interior annulus, be connected with connecting rod.
Described magnet is arranged on mount pad, and described mount pad passes described interior annulus and is threaded with described interior annulus.
Described washer is arranged on above described magnet, is connected between described mount pad with described washer by multiple joint pin.
Adopt technique scheme, of the present utility model pair of film earphone horn, when after voice coil loudspeaker voice coil energising, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces can along with changing, active force is produced, Continuous Drive first vibrating diaphragm, the second vibrating diaphragm vibrations sounding with magnet.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing earphone horn.
Fig. 2 is the structural representation of earphone horn in the utility model.
Fig. 3 is the structural representation of lower cover in the utility model.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2,3, the utility model provides a kind of two film earphone horn, comprises circular shell 201, magnet 204, washer 211, voice coil loudspeaker voice coil 205, first vibrating diaphragm 206a, the second vibrating diaphragm 206b, dust cap 207, lower cover 202, first bullet ripple 208a, the second bullet ripple 208b; Wherein magnet 204 is fixed on lower cover 202, and described voice coil loudspeaker voice coil 205 is enclosed within outside described magnet 204; On the first vibrating diaphragm 206a above the upper end of described voice coil loudspeaker voice coil 205 is fixed on and is positioned at, on the second vibrating diaphragm 206b below the other end is fixed on and is positioned at; Described dust cap 207 is located at the top of described voice coil loudspeaker voice coil 205, and described first plays ripple 208a is connected between described voice coil loudspeaker voice coil 205 upper end and described shell 201, and described second plays ripple 208b is connected between described voice coil loudspeaker voice coil 205 lower end and described shell 201.
Described lower cover 202 comprises the outer toroid 202a and interior annulus 202b that arrange with one heart, between described outer toroid 202a and interior annulus 202b, be connected with connecting rod 202c.
Described magnet 204 is arranged on mount pad 212, and described mount pad 212 passes described interior annulus 202b and is threaded with described interior annulus 202b.
Described washer 211 is arranged on above described magnet 204, is connected between described mount pad 212 with described washer 211 by multiple joint pin 212.
Adopt technique scheme, of the present utility model pair of film earphone horn, when after voice coil loudspeaker voice coil energising, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces can along with changing, active force is produced, Continuous Drive first vibrating diaphragm, the second vibrating diaphragm vibrations sounding with magnet.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
