Magnetic circuit component 3 generally includes magnet 31, T iron 32.In some embodiments, since the structure difference of T iron 32 can volume Additional washer 33 outside.In this implementation, washer 33 is fixed in T iron 32.

The whole T iron 32 is in T-shaped comprising hollow cylinder 321 and annular partition 322, cylinder 321 and partition 322 It can be integrally formed or independent molding, partition 322 are annular in shape and generally around in the middle position of the cylinder 321；Such as Fig. 3 institute Show, the hollow part of cylinder 321 is the voice guide hole 30 for leading note, top and bass unit of the cylinder 321 close to bass unit Third fixed ring 24 be in contact, the bottom end of the close voice unit of cylinder 321 is equipped with washer 33, and washer 33 is used for magnetic conduction, For the usually lower mild steel of phosphorus content to reduce magnetic resistance, it usually constitutes magnetic circuit, in other embodiments, institute with T iron, magnet Stating washer 33 can be integrally formed with T iron；In general, washer 33 and T iron 32 use identical material when the material of T iron 32 is harder 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 carry out reinforcing that T iron 32 is avoided to deform to T iron 32.

Ringshaped magnet 31, set are provided between the lower surface and frame 4 of the close voice unit of the partition 322 of T iron 32 Set on the outside of cylinder 321, so that magnet 31 is folded between the lower surface of partition 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 is equipped with input terminal and (does not show in figure External power supply is connected out), to provide source of sound and the current signal input of loudspeaker, and current signal is passed into high pitch voice coil 12 With bass coil 22.

The close middle 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 first lead slot 15, and wherein first lead (not shown) is drawn from first lead slot 15, and edge It extends to high pitch voice coil 12 on the inside of tweeters diaphragms 11 to be connected electrically, to provide current signal to high pitch voice coil 12, first draws The other end of line is connect by first 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, the 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 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 with realizing to the bass coil 22, to drive bass coil 22 to vibrate.In other embodiments, described second draws Line can be also connected to otherwise in bass coil 22.

T iron 32 in magnetic circuit component 3 is in hollow columnar, and it cooperates cyclic annular tweeters diaphragmse 21, 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 protrudes 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, which is passed through tone currents, can generate 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, so that most sound wave that voice unit issues 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.Described 22 one end of bass coil connects tweeters diaphragmse 21, and the other end protrudes into chamber between bass In 20, the magnet 31 is that bass coil 22 provides fixed magnetic field, and tone currents is passed through in bass coil 22 can generate variation The fixed magnetic field that magnetic field, changing magnetic field and magnet 31 provide interacts, 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 Most sound wave of sending can be communicated up through vibrating diaphragm 21.

Since the T iron 32 in magnetic circuit component 3 is in hollow columnar, and cooperate 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 intracavitary air of two sounds does not circulate mutually, therefore air crosstalk does not occur, avoids the generation of audio mixing. It is exported specifically, the voice unit issues sound wave by voice guide hole 30, and the sound wave that bass unit issues directly spreads out of loudspeaking Device 100, two groups of sound independently issue as a result, and 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 loudspeaker 100, as known to those skilled in the art , the earphone further includes the earphone case for installing the loudspeaker 100, and to the loudspeaker 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 loudspeaker 100.

Embodiment of above is only for interpreting the claims.The right protection scope of the utility model is not limited to Bright book.Anyone skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in Change or replace, is included within the protection scope of the utility model.
