In the inner chamber of fixed frame, gap vacantly is formed between fixed frame 21 and oscillating plate for end；Tibial membrane is arranged on fixed frame, will be whole
Individual oscillating plate 22 is outstanding to be covered so that the first cavity 13 separates with the sealing of the second cavity 14, and two cavitys do not connect.
For example, tibial membrane 23 is by being adhesive on fixed frame 21 and oscillating plate 22, or tibial membrane 23 is existed by glue sticking
21 on fixed frame, the preset clearance formed between the free end of oscillating plate 22 and fixed frame 21 is sealed, the material of tibial membrane 23
Preferably polymer compound film, such as PVC, PE composite membrane etc..
After being powered to driving structure, driving structure driving ultrasonic transformer 3 drives oscillating plate 22 to do and set perpendicular to vibrating diaphragm mechanism
Put the of reciprocating vibration of direction.It should be noted that the setting direction for the vibrating diaphragm mechanism being related in text refers to that oscillating plate 22 is in
Under inactive state, the setting direction of vibrating diaphragm mechanism, in the present embodiment 1, vibrating diaphragm mechanism is horizontally disposed, accordingly oscillating plate 22
Direction of vibration is vertical direction.
As shown in figure 1, driving structure is rounded piezoelectric vibrator 4, it is vacantly arranged in the second cavity 14.For example,
Support frame is provided with second shell body, piezoelectric vibrator 4 is arranged on support frame, and is be arranged in parallel with fixed frame 21；Or do not set
Support frame is put, is directly arranged on the circumferential edge of piezoelectric vibrator 4 in the interior sidewall surface of second housing, two kinds of mounting means cause
Piezoelectric vibrator 4 and second has vibration gap between bottom surface.
As shown in Fig. 2 piezoelectric vibrator 4 include set gradually from top to bottom the first piezoelectric ceramics 41, separation layer 42 and
Second piezoelectric ceramics 43.Separation layer 42 is conductor, for example with iron plate or copper sheet.First piezoelectric ceramics 41 and the second piezoelectric ceramics
43 itself polarized, two faces are respectively positive pole and negative pole.First piezoelectric ceramics 41 and the homopolarity of the second piezoelectric ceramics 43 during setting
Relatively, such as the lower surface of the first piezoelectric ceramics 41 is negative pole, and the top surface of the second piezoelectric ceramics 43 is negative pole.First piezoelectricity is made pottery
The top surface connection positive electrode of porcelain 41, the lower surface connection negative electrode of the second piezoelectric ceramics 43.First piezoelectric ceramics 41, every
The piezoelectric ceramics 43 of absciss layer 42 and second forms the loop of a series connection.Positive electrode and negative electrode connect AC power input respectively
End, when positive electricity extremely positive voltage, negative electricity extremely negative voltage when, by inverse piezoelectric effect, the first piezoelectric ceramics 41 extends, the second pressure
Electroceramics 43 shrinks, and piezoelectric vibrator 4 produces convex bending deformation；When positive electricity extremely negative voltage, negative electricity extremely positive voltage when, pass through
Inverse piezoelectric effect, the first piezoelectric ceramics 41 shrink, and the second piezoelectric ceramics 43 extends, and piezoelectric vibrator 4 produces bow deformation, by
In the regular exchange of alternating current both positive and negative polarity so that piezoelectric vibrator 4 produce it is regular pump, so as to drive vibration
Plate is realized of reciprocating vibration.

First arm of force between fixing point and the first fulcrum on bar is L1, the second power of the free end of connecting rod 5 to the first fulcrum Z1
Arm is L2, and the resistance that the free end of ultrasonic transformer 3 and connecting rod 5 is subject to respectively is F1 and F2, is drawn by lever principle, formula one：
F1*L1=F2*L2.Due to L1<L2 causes F1>F2, namely when the resistance suffered by ultrasonic transformer 3 is F1, suffered by oscillating plate 22
Resistance F3 ＜ F1, oscillating plate 22 is smaller by resistance, its be easier vibrate, Oscillation Amplitude increase, pass through setting so as to realize
Connecting rod 5, further increase the function of the sound of receiver.
For connecting rod 5, connecting rod 5 is L-shaped, and the end of the horizontal part of L-shaped is as fixing end, the end of vertical portion
As free end；Or connecting rod 5 is in horizon bar, connecting rod 5 is fixedly connected with oscillating plate 22 by vertical connecting rod.
As shown in figure 1, above-mentioned receiver, in addition to the sender 15 being opened in the side wall of the first housing 11 and fixation
The sound guide tube 6 being contained within the outer surface of the first housing 11 and by sender 15.Driving hair when oscillating plate 22 vibrates
Sound film 23 agitates the air movement in the first cavity 13 so that sends required sound in the first cavity 13, sound passes through again
Sender 15 enters in sound guide tube 6 and then blazed abroad.

And the fixing end of two connecting rods 5 is located at the both sides of the second housing respectively, or the homonymy of the second housing can also be located at.
The middle part of circular piezoelectric vibrator 4 is mounted on by ultrasonic transformer 3 in the connecting rod 5 of lower section, and ultrasonic transformer 3 is connecting
Fixing point on bar 5 is located between two ends of the connecting rod 5, is consolidated so that underlying connecting rod 5 is formed with it
Fixed end is the first fulcrum Z1 primary lever, as shown in fig. 7, the first power between the fixed peace of ultrasonic transformer 3 and the first fulcrum Z1
Arm is L1, and second arm of force of free end to the first fulcrum of one-level bar thick stick is L2, ultrasonic transformer 3 and primary lever free end difference
The resistance being subject to is F1 and F2, is drawn by lever principle, formula one：F1*L1=F2*L2.
Similarly, connecting rod 5 above forms the second lever using its fixing end as the second fulcrum Z2, second lever
Free end to the second fulcrum Z2 the 3rd arm of force be L3, free end to the second fulcrum Z2 of primary lever the 4th arm of force are
Resistance suffered by L4, the free end of second lever and the free end of primary lever is respectively F3 and F2, is drawn by lever principle,
Formula two：F3*L3=F2*L4, formula one is combined with formula two, F3=[(L1*L3)/(L2*L4)] F1 is drawn, due to L2 ＞
L1, while L4 ＞ L3 so that F3 ＜ F1, that is, when the resistance suffered by piezoelectric vibrator 4 is F1, the resistance suffered by oscillating plate 22
Power F3 ＜ F1, oscillating plate 22 is smaller by resistance, and it is easier to vibrate, Oscillation Amplitude increase, so as to realize by setting two-stage
Lever, further to increase the function of the sound of receiver.
