Stating washer 33 can be integrally formed with T iron；In general, when the material of T iron 32 is harder, washer 33 uses identical material with T iron 32
Matter is simultaneously integrally formed；When the material is soft for T iron 32, washer 33 is then fastenedly connected using harder material and with the T iron 32,
To be reinforced that T iron 32 is avoided to deform to T iron 32.
It is provided with ringshaped magnet 31, set between the lower surface and frame 4 of the close voice unit of the partition board 322 of T iron 32
Set on the outside of cylinder 321, to which magnet 31 is folded between the lower surface of partition board 322 and frame 4, magnet 31 is solid for providing
Fixed magnetic field.In addition, the lower surface of the bottom end of frame 4 is connect with circuit board 5, circuit board 5 (does not show equipped with input terminal in figure
Go out) connection external power supply, it is inputted with the source of sound and current signal that provide loud speaker, and current signal is passed into high pitch voice coil 12
With bass coil 22.
The close centre position of protection cap 8 is equipped with the first damping screen 6, to adjust the air pressure in voice unit.The basin
The side of 4 bottom end of frame is equipped with the first wire lead slot 15, wherein the first lead (not shown) is drawn from the first wire lead slot 15, and edge
11 inside of tweeters diaphragms extends to high pitch voice coil 12 and is connected electrically, and to provide current signal to high pitch voice coil 12, first draws
The other end of line is connect by the first wire lead slot 15 with circuit board 5, and what this technology belonged to earphone field notes technology, passes through first
Lead, which is realized, is powered to high pitch voice coil 12, and high pitch voice coil 12 is driven to vibrate.In other embodiments, first lead can also lead to
It crosses and is otherwise connected on high pitch voice coil 12.
The outer edge side on the close top of the frame 4 is equipped with the second damping screen 7, to adjust the gas in bass unit
Pressure.The side on 4 top of the frame is equipped with the second wire lead slot 25, wherein one end of the second lead (not shown) and bass sound
22 connection of circle, the second lead other end are stretched along the outer rim edge of frame 4 by the second wire lead slot 25 and are connected with circuit board 5
It connects, is powered to the bass coil 22 with realizing, to drive bass coil 22 to vibrate.In other embodiments, described second draws
Line can be also otherwise connected in bass coil 22.
T iron 32 in magnetic circuit component 3 is in hollow columnar, and the cyclic annular tweeters diaphragmse 21 of its cooperation, tweeters diaphragms 11 and frame
Each component parts such as 4 form closed high pitch sound chamber 10 and bass sound chamber 20.The high pitch sound chamber 10, bass sound chamber 20
It forms specific as follows：
Tweeters diaphragms 11, the first fixed ring 13, magnetic circuit component 3 enclose a closed high pitch sound chamber 10, high pitch jointly
12 one end of voice coil connects vibrating diaphragm 11, and the other end stretches into high pitch sound chamber 10, and magnet 31 is that the high pitch voice coil 12 provides fixed magnetic
, high pitch voice coil 12 is passed through tone currents and will produce changing magnetic field, the fixed magnetic field phase that changing magnetic field is provided with magnet 31
Interaction, same polarity magnetic field is mutually exclusive, and opposed magnetic field attracts each other.Due to high pitch voice coil 12 and 11 phase of tweeters diaphragms
Even, high pitch voice coil 12 is repelling and tweeters diaphragms 11 is driven to vibrate air with sounding under attracting active force.At this point, high pitch sound chamber
Air in 10 is extruded or expands, to which most sound wave that voice unit is sent out can be communicated up by voice guide hole 30.
In addition, cyclic annular tweeters diaphragmse 21, the second fixed ring 23, third fixed ring 24, magnetic circuit component 3 and frame 4 are enclosed jointly
Synthesize a closed bass coil 20.22 one end of the bass coil connects tweeters diaphragmse 21, and the other end stretches into chamber between bass
In 20, the magnet 31 is that bass coil 22 provides fixed magnetic field, and being passed through tone currents in bass coil 22 will produce variation
Magnetic field, changing magnetic field interact with the fixed magnetic field that magnet 31 provides, and same polarity magnetic field is mutually exclusive, opposed magnetic field
It attracts each other.The bass coil 22 is connected with tweeters diaphragmse 21, and the bass coil 22 is under repulsion and attracting active force
The tweeters diaphragmse 21 is driven to vibrate air with sounding.Therefore the air in bass sound chamber 20 is extruded or expands.Bass unit
The most sound wave sent out can be communicated up through vibrating diaphragm 21.
Since the T iron 32 in magnetic circuit component 3 is in hollow columnar, and coordinate cyclic annular tweeters diaphragmse 21, tweeters diaphragms 11 and basin
Each component part such as frame 4, form above-mentioned high pitch sound chamber 10, with bass sound chamber 20, and two independent separated sound chambers, although altogether
With a magnet 31, but the air of two sound intracavitary does not circulate mutually, therefore air crosstalk does not occur, avoids the generation of audio mixing.
It is exported by voice guide hole 30 specifically, the voice unit sends out sound wave, and the sound wave that bass unit is sent out directly outflow is raised one's voice
Device 100, as a result, two groups of sound independently send out, sound field separation generates clean sound quality.
In other embodiments, voice unit, can replace with bass unit position.
Present embodiment also provides a kind of earphone, and the earphone includes the loud speaker 100, and those skilled in the art know
, the earphone further includes the earphone case of the installation loud speaker 100, and to the loud speaker 100 provide source of sound and
The cable of electric current input.The cable is connected to the input terminal on the circuit board 5 in loud speaker 100.
Embodiment of above is only for interpreting the claims.Right protection scope of the present invention is not limited to illustrate
Book.Any one skilled in the art in the technical scope of present disclosure, the variation that can readily occur in or
It replaces, is included within the scope of the present invention.
