Vibrational system.The major parameter amount of vibrational system is stiffness (mechanical stiffness), quality, mechanical impedance, is changed by the change of structure, optimization
These three parameter amounts are able to achieve, reach required expected requirement.
After one sound system reaches stable state, acoustic pressure (corresponding to frequency response) is able to maintain constant, diaphragm when to make frequency shift
22 displacement just must be constant, and the movement velocity of diaphragm 22 is V, and driving force F, the mechanical impedance of vibrational system is Z, vibrating diaphragm
Displacement is ξ, and the angular frequency of vibration is ω, then vibrational system meets following formula relationship:
I.e. under the conditions of certain driving force, vibrational system is necessary for mechanical stiffness control system namely the impedance of vibrational system must
It must be mechanical stiffness, and:
When driving force frequency f is far below the intrinsic frequency f of vibrational system0, i.e. f < f0When, the elasticity of vibrational system is to vibration
System plays main function, and vibrational system is in area with flexible control.And when driving force frequency f is much larger than the intrinsic frequency of vibrational system
Rate f0, i.e. f > f0When, the quality of vibrational system plays main function to vibrational system, and vibrational system is in quality control zone.It is right
Meet following formula relationship in vibrational system its resonant frequency:
In the formula, K is the stiffness of vibrational system, and m is the quality of vibrational system moving component.

Piece 22 is fixed on the root on frame 21 and carries out local reduction, can also improve the low frequency performance of receiver.
And resonant frequency f should be made in high band0It is as big as possible, i.e., increase the stiffness of diaphragm 22, as far as possible to improve high frequency
Response, to obtain wider effective band.And reduce the motional inertia of vibrating diaphragm 22 as far as possible to improve transient response.And this
One condition can carry out certain process by the non-magnetic active region (free end of diaphragm) to diaphragm front, by this portion
Divide diaphragm to be thinned or inlay ultra-thin light alloy piece and suppresses the technology mode of reinforcing rib 226 on it to realize.
For example, the thickness of the second part of diaphragm 22 is less than the thickness of first part, so that the quality of diaphragm 22 mitigates,
To increase the high frequency performance of receiver.Or only the hanging end part of diaphragm 22 is thinned.
The gas chamber (the first cavity 13) for being V for a volume, when the vibration displacement amplitude ξ of diaphragm 22 is steady state value,
The acoustic pressure P that the effective area S of diaphragm generates vibration just plays key effect, and has following formula relationship:
C is the velocity of sound, P in the formula0For benchmark acoustic pressure.
