For in vibrating diaphragm mechanism 2, as shown in Figure 7 to 10, two had in the end of the free end 212 of reed 21
Unfilled corner 2121, the end of free end 212 is trapezoidal.For reed 21, on the premise of the length of reed 21 is constant, free end
212 width is smaller, free end 212 it is easier vibration and vibration frequency is higher, improve reed 21 vibrate high frequency performance it is better.
That is, change reed 21 vibration frequency of itself so that the resonance point between reed 21 and air is shifted, so as to improve spring
The high frequency performance that piece 21 vibrates.Most preferably, two unfilled corners 2121 make it that the end of the free end 212 of reed 21 is triangular in shape, or
Person's taper.If only need to slightly improve the high frequency performance of the vibration of reed 21, it is possible to reduce the area of two unfilled corners 2121, or
One unfilled corner 2121 is only set.
As shown in Figure 7 to 10, six high sound hole 216 is offered on the free end 212 of reed 21, in the vertical root of reed 21
On the direction of portion side, high sound hole 216 is distributed in the range of the 2/3-1 of the length of reed 21 at 211, self-retaining end.For example, high pitch
The bore in hole 216 in the range of 0.003mm-0.01mm, such as 0.003mm, 0.004mm, 0.005mm, 0.006mm,
0.007mm, 0.008mm, 0.009mm, 0.01mm etc., in this range, the bore of high sound hole 216 are smaller, and reed 21 vibrates
Frequency it is higher, it is better that the audio performance of high pitch is enhanced, but the bore of high sound hole 216 is less than after 0.003mm, and high pitch is changed
Improvement degree when kind degree is in the high bore of sound hole 216 for 0.003mm, after now bore reduces again, it is beyond height
Sound pushes the polarity number of energy, even if reducing bore again, also will not further improve high pitch, this and the material of of reed 21 itself
It is related to the performance of structure.It is more than 0.01mm it is of course possible to design the bore of high sound hole 216, now improves the degree of high pitch
It is very weak, it is hardly further to improve high pitch.In a word, the setting of high sound hole 216, is not changing the premise of the length of reed 21
Under, it can further improve the high frequency performance of high pitch.
For reed 21, when the width of reed 21 is constant, the length of reed 21 is smaller, to the improvement performance of bass
Better, in order to not influence high frequency performance, the present embodiment opens up middle pitch on the premise of the length of reed 21 is not reduced on reed 21

0.9mm, 1mm etc., the bore in certain bass hole 214 might be less that 0.1mm, and it also has improvement result to low frequency performance, but
It is that improvement result is weaker；The bore of bass hole 214 can also be more than 1mm, but the bore in bass hole 214 is more than after 1mm, and it improves
As improvement degree when the degree of low frequency performance and the bore of bass hole 214 are 1mm, because the bore of bass hole 214 is more than 1mm
Afterwards, the limit range of energy is pushed beyond bass, even if increasing bore again, further improve also no longer is played to bass and is made
With.When the bore in bass hole 214 is in the range of 0.1mm-1mm, the aperture in bass hole 214 is bigger so that the frequency that reed 21 vibrates
Rate is lower, and the quality of bass is better.Two bass holes 214 can be evenly distributed in the fixing end 211 of reed 21, can also

Deng, within this range, when the bore of middle sound hole 215 more tends to median, its vibrate frequency it is higher, its frequency performance is enhanced
It is better, when the bore of middle sound hole 215 is closer to two marginal values (0.01mm or 0.1mm), vibration frequency is lower, its improve
The effect of middle pitch is weaker, but still has improvement result, and the bore of central sound hole 215 is after two boundary values, and middle pitch is enhanced
Degree very little.
