Embodiment 1

The present embodiment provides a kind of vibrating diaphragm mechanism applied to receiver, as shown in Figure 1 to Figure 3, including fixed frame 1, spring Piece 2 and sound film 3.Wherein, fixed frame 1 has hollow lumen.

Reed 2 is made of permeability magnetic material, such as iron-nickel alloy, is passed through admittedly as shown in figure 1, the one end of reed 2 is root side Fixed end 21 is connected with fixed frame 1, and gap 5 is left between other sides and fixed frame 1, and is vacantly arranged in hollow lumen, spring One end relative with fixing end 21 is free end 22 on piece 2, and the free end 22 is done of reciprocating vibration by the driving of electromagnetic mechanism；Such as figure Shown in 3, sound film 3 is all attached on whole fixed frame 1 and is covered on reed 2, with the formation of seal clearance 5 in fixed frame 1 And the gas channel between the upper and lower surface of reed 2.For example, correspond to fixed frame 1 and reed 2 on a side surface of sound film 3 Opening position sets glue, and sound film 3 is fixed on fixed frame 1 and reed 2 by glue.That is, sound film 3 by fixed frame 1 and reed 2 it Between gap 5 seal, the hole of any structure is not opened up on sound film 3, the gas in the side of fixed frame 1 cannot pass through sound film 3 Into the space of opposite side.

Vibration frequency of the edge shape of the side in the corresponding gap 5 of reed 2 according to needed for reed 2 determines, to improve reed 2 The high pitch performance of vibration.As shown in figure 3, the edge shape of the side of reed 2 is, two had in the end of reed free end 22 Unfilled corner 221, the end of free end 22 are trapezoidal.For reed 2, on the premise of the length of reed 2 is constant, free end 22 Width is smaller, free end 22 it is easier vibration and vibration frequency it is higher, improve reed 2 vibrate high frequency performance it is better.That is, change Change reed 2 vibration frequency of itself so that the resonance point between reed 2 and air shifts, so as to improve the vibration of reed 2 High frequency performance.Most preferably, two unfilled corners 221 make it that the end of the free end 22 of reed 2 is triangular in shape, or taper.If only need When slightly improving the high frequency performance that reed 2 vibrates, it is possible to reduce the area of two unfilled corners 221, or a unfilled corner is only set 221。

As shown in figure 1, six high sound hole 26 is offered on the free end 22 of reed 2, in the direction of 2 vertical root side of reed On, high sound hole 26 is distributed in the range of the 2/3-1 of the length of reed 2 risen at self-retaining end 21.For example, the bore of high sound hole 26 exists In the range of 0.003mm-0.01mm, for example, 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 26 are smaller, and the frequency that reed 2 vibrates is higher, the sound of high pitch After frequency performance is enhanced better, but the bore of high sound hole 26 is less than 0.003mm, the degree that high pitch is enhanced is in high pitch Improvement degree when the bore of hole 26 is 0.003mm, after now bore reduces again, it pushes the polarity number of energy beyond high pitch, i.e., Make to reduce bore again, also will not further improve high pitch, the material of this and reed 2 itself and the performance of structure are related.Certainly 0.01mm can be more than by what the bore of high sound hole 26 designed, now the degree of improvement high pitch is very weak, hardly further Improve high pitch.In a word, the setting of high sound hole 26, on the premise of the length of reed 2 is not changed, high pitch can further be improved High frequency performance.

For reed, when the width of reed 2 is constant, the length of reed 2 is smaller, and the improvement performance to bass is got over Good, in order to not influence high frequency performance, the present embodiment is not on the premise of the length of reed 2 is reduced, sound hole 25 in being opened up on reed 2 With bass hole 24, to improve the frequency performance and low frequency performance of reed vibration, during high pitch, middle pitch and bass is improved, Any pore structure will not be opened up on sound film 3.
