One end of the voice coil 2 is set calmly, and the magnet steel system 3 is the prior art comprising magnet steel and magnetic conductive board.The magnet steel system
3 are inserted in the voice coil 2.Air-flow can gap between the voice coil 2 and the U iron 1 and the voice coil 2 with it is described
The heat release hole 111 is flowed and leads in gap between magnet steel system 3, forms convection channel.When loudspeaker works in low-frequency range
When, the voice coil 2 significantly longitudinally reciprocating motion forces the convection channel on hot and cold air edge to flow, i.e., described in cold airflow flow direction
Voice coil 2, thermal current flows to 20 region of radiator, for convection heat dissipation, accelerates radiating rate.Loudspeaker is in medium-high frequency section
When work, in the case where 2 amplitude of voice coil is little, the voice coil 2 generates heat transfer to the U iron 1, due to the U
Iron 1 is completely embedded with the mounting cylinder 20, so that U iron 1 transfers heat in the installing pipe 21, and due to each described scattered
The side of hot fin 22 is connect with the annular interconnecting piece 11, and the frame main body 10 is made to be connected as one with the radiator 20
It is whole, and then heat can be transmitted on the frame main body 10 and the radiator 20, and the frame main body 10 is dissipated with described
Hot device 20 outwardly dissipates heat.
As shown in fig. 6, loudspeaker low-frequency range work when, since inside loudspeakers vibrational system significantly moves back and forth,
Hot and cold air passes through the heat release hole 111 and enters and leaves loudspeaker, and the thermal current in the frame main body 10 is forced to flow to described dissipate
Hot device 20, cold airflow enter loudspeaker 20 from the heat release hole and radiate, and hot and cold air passes through the radiating fin
Gap between 22 enters and leaves loudspeaker, realizes heat loss through convection, improves radiating efficiency.Meanwhile no matter loudspeaker works in low-frequency range,
Or loudspeaker works in medium-high frequency section, and in the case where the amplitude of inside loudspeakers vibrational system is little, loudspeaker is by heat
It can all be transmitted in the installing pipe 21, and since the side of each radiating fin 22 and the annular interconnecting piece 11 connect
It connects, the frame main body 10 is made to be connected as an entirety with the radiator 20, thus the frame main body 10 and the heat dissipation
It radiates on device 20, is outwardly radiated heat by way of increasing heat dissipation area, improve the radiating efficiency of loudspeaker, it is real
Heat loss through conduction and heat loss through radiation are showed.

31 position, the screw 9 pass through the threaded hole 312 and the magnetic circuit system 50 and the frame 30 are fixed together.And
The surrounding of the magnetic circuit system 50 is arranged in 40 annular of radiating fin, to guide the air-flow entered and left from heat release hole 322.Separately
Outside, the magnetic circuit system 50 seals the basin bottom 31, and the centring disk 6, voice coil 7 and dust cover 8 are by the frame 30
Interior another side seal makes to form an airtight chamber in addition to heat release hole 322 in frame 30, and the diameter of the voice coil 7 is less than
The diameter of the mounting hole 311, the diameter for plugging portion 512 of the T iron 51 is less than the diameter of the voice coil 7, so that air-flow can
Pass through clearance flow between the gap plugged between portion 512 and the voice coil 7, the voice coil 7 and the mounting hole 311
It is dynamic, and a cold and hot convection channel is formed with the heat release hole 322.When full frequency speaker is in low frequency operation and 7 band of the voice coil
When moving the dustproof cover 8 significantly reciprocation type vibrating, the voice coil 7 is made to be formed by the air in confined space with dust cover 8
Plug-type movement is formed, i.e., cold and hot convection current when voice coil 7 is moved to 50 direction of magnetic circuit system in the hot-air of surrounding by design
Channel is pushed out from heat release hole 322, and the voice coil 7 to far from 50 direction of magnetic circuit system move when the external world cold air again from
It is sucked into heat release hole 322 and, the hot and cold air near voice coil 7 is completed by forced convection radiating mode and is exchanged.Work as loudspeaker
When in medium-high frequency work, Oscillation Amplitude becomes smaller, since the magnetic circuit system 50 is fixedly connected with the frame 30, the voice coil 7
The heat of generation passes through on 50 heat loss through conduction fin 40 of magnetic circuit system, and the radiating fin 40 increases heat loss through radiation area.
Compared with prior art, the frame provided by the utility model with heat sinking function passes through in the frame main body 10
On heat release hole 111 and the radiator 20 that links together with the frame main body 10 radiate.And it is every on radiator 20
