In second gripper shoe 112, the diameter of second gripper shoe 112 is less than first gripper shoe 111 for shake part 12
Diameter.
Seen from the above description, de-noising component arranges two-stage shock-damping structure, and vibration carries out one when being delivered to supporting part
Level damping, vibration is delivered to miaow head to be needed through bolster, and bolster can carry out secondary shock-absorbing, be effectively guaranteed picking up for miaow head
Sound quality.
Further, the surface of the shock absorber part 12 is provided with frosted layer.
Seen from the above description, shock absorber part surface arranges frosted layer, other portions of miaow head when shock absorber part can be avoided to deform
Position is bonded on shock absorber part.Prevent the mode that other positions of miaow head are bonded in shock absorber part from having a lot, for example, set on shock absorber part surface
Put bar shaped annular knurl, coat diaphragm etc. near the part of miaow head region to shock absorber part.
Further, the de-noising component 1 also includes sponge 13, and the sponge 13 is contained in the hollow structure and supports
The madial wall of the shell 2 is held, the sponge 13 is the hollow cylinder that one end has opening, the miaow head 3 and the shock absorber part
12 are contained in respectively in the hollow cylinder.
Seen from the above description, the sponge audio amplifier that can decay is set the sound of miaow head is passed to by air, from other canal
Road carries out de-noising, the occurrence of reduction is uttered long and high-pitched sounds so that the de-noising channel of de-noising component is more perfect, de-noising effect more preferably.
Further, the thickness of the sponge 13 is 3mm-5mm.
Further, the supporting part 11 and the clamping of the shell 2 or it is threadedly coupled.
Further, the audio amplifier 5 is detachably connected with the shell 2.
