Side is fixedly connected with limit plate 20, and limit plate 20 is movably connected in the inside of shock-reducing sleeve 15, the side of elastic 14 and installation
The side of plate 10 is fixedly connected, and the outer wall of elastic 14 is connected with reset spring 16, is between mounting plate 10 and loudspeaker 11
It is fixedly connected, so can be transferred to vibration force on mounting plate 10 when loudspeaker 11 are worked, mounting plate 10 will vibrate
Power is transferred to respectively on support rod 13, elastic 14 and elastic webbing 18, when vibration force is transferred on support rod 13, can make vibration damping
Set 15 is moved in 13 outer wall of support rod, and squeezes elastic 14, and making 14 stress of elastic, deformation occurs, and pressed home bullet
Spring 16 makes 16 forced compression of reset spring, decomposes to vibration force, reduces the vibration force that loudspeaker 11 generate, disappears in vibration force
After mistake, under the drive of reset spring 16, elastic 14 is made quickly to restore to the original state, and restore mounting plate 10 to original position
It sets, one end of reset spring 16 is fixedly connected on the side of mounting plate 10, and the other end of reset spring 16 is fixedly connected on and subtracts
The side of vibration plate 12, the side of mounting plate 10 offer fixation hole 17, and the quantity of fixation hole 17 is four, every two fixation hole 17
It is one group, and two groups of fixation holes 17 are symmetrically distributed in the side of mounting plate 10, fixation hole using the middle line of mounting plate 10 as symmetry axis
17 inside is fixedly connected with elastic webbing 18, and the side of fixation hole 17 is fixedly connected with reinforcement block 21, and the quantity of reinforcement block 21 is
Four, elastic webbing 18 is fixed on the inside of fixation hole 17, and setting reinforcement block 21 is the fixation in order to enhance elastic webbing 18, prevents bullet
Property band 18 work when, since float force is excessive, and elastic webbing 18 is made to have the case where falling off inside fixation hole 17, upper spacer 5
Bottom and the top of lower clapboard 6 be fixedly connected to fixing seat 19, one end of elastic webbing 18 is fixedly connected on fixing seat 19
Inside will drive elastic webbing 18 and shaken when mounting plate 10 gradually vibrates, and elastic webbing 18 is by part on mounting plate 10
Vibration force is cut down, and is cooperated support rod 13 and elastic 14 to decompose vibration force, is prevented box house with loudspeaker 11
Work and generate resonance, protect the components inside speaker, by setting elastic webbing 18, elastic 14 and shock-reducing sleeve 15,
Speaker can be made to have the function of preventing resonance, the vibration that loudspeaker 11 generate is disappeared using elastic webbing 18 and elastic 14
Subtract, protects the components inside speaker to greatest extent, ensure that acoustical quality when speaker uses, while improving speaker
Service life.
It can to sum up obtain, by setting elastic webbing 18, elastic 14 and shock-reducing sleeve 15, speaker can be made to have to be prevented the present invention
The vibration that loudspeaker 11 generate is cut down using elastic webbing 18 and elastic 14, protects sound to greatest extent by the function of resonance
Components inside case ensure that acoustical quality when speaker uses, while improve the service life of speaker, loudspeaker 11 into
When row work, vibration can be generated, vibration force can be transferred in rubber rods 9, vibrate rubber rods 9, because of rubber rods 9
For rubber material, vibration force itself meeting puberty deformation is encountered, and reduces the transmitting of vibration force, reduces the resonance inside speaker,
To be fixedly connected between mounting plate 10 and loudspeaker 11, so vibration force can be transferred to installation when loudspeaker 11 are worked
On plate 10, vibration force is transferred on support rod 13, elastic 14 and elastic webbing 18 by mounting plate 10 respectively, when vibration force is transferred to
When on support rod 13, shock-reducing sleeve 15 can be made to be moved in 13 outer wall of support rod, and squeeze elastic 14, make 14 stress of elastic
Deformation occurs, and pressed home spring 16, makes 16 forced compression of reset spring, decomposes to vibration force, reduces loudspeaker 11 and produces
Raw vibration force under the drive of reset spring 16, makes elastic 14 quickly restore to the original state, and make to pacify after vibration force disappearance
The recovery of loading board 10 will drive elastic webbing 18 and shaken to original position when mounting plate 10 gradually vibrates, elastic webbing
18 cut down part vibration force on mounting plate 10, cooperate support rod 13 and elastic 14 to decompose vibration force, prevent
Box house generates resonance with the work of loudspeaker 11, protects the components inside speaker, by setting upper spacer 5, under
Partition 6 and gas port 7 can effectively enhance the circulation of speaker internal gas flow, when speaker 11 being made to be worked, air-flow
Flowing is more unobstructed, and front and back rhythm rushes when effectively preventing air-flow and rebound inside speaker, and speaker being caused to work
Prominent the case where causing speaker internal resonance generation, reduces the resonance of speaker, ensure that audio quality when speaker uses, on every
Cavity is formed between plate 5 and top plate 2, also forms cavity between lower clapboard 6 and bottom plate 3, when speaker is worked, can be produced
Anger stream, air-flow are flowed inside speaker, and enter cavity inside by gas port 7, then arrange air-flow by venthole 8
Speaker out reduces the current rate inside speaker, to effectively prevent air-flow, mutually rebound generates oscillation inside speaker,
And make to vibrate inside speaker, it solves existing speaker and does not have the function of preventing cabinet from resonating mostly, make box house
Components and loudspeaker generate resonance, not only influence whether the playing quality of speaker, but also long-term resonance, can also damage case
The problem of body internal component, makes speaker be damaged, and reduces the service life of speaker.
