Embodiment two
Diaphragm-vibrating type linear motor in embodiment one, power drive structure include third magnet on oscillator 3 and are located at upper cover 11
The second coil 5, the oscillation intensity of diaphragm-vibrating type linear motor is small, it is often necessary to be driven using multiple diaphragm-vibrating type linear motors
Moving-target object.
What is different from the first embodiment is that the present embodiment also improves the power drive structure of diaphragm-vibrating type linear motor.
As shown in fig. 6, in the present embodiment, oscillator 3 includes permanent magnet and the fixed block for fixed permanent magnet
6.Permanent magnet includes the first permanent magnet 81 and the second permanent magnet 82.On oscillator 3, the first permanent magnet 81 and second is forever
The magnetic pole of long magnet 82 is oppositely arranged.
Electromagnet 7 includes iron core 71 and the first coil 72 being wrapped on iron core 71, is applied in the first coil 72
Current direction is in periodically variable alternating current.The waveform of alternating current can be sine curve, and waveform may be triangle
Shape wave, square-wave.But alternating current used in life preferably can be used, be exactly the alternating current with sinusoidal waveform.
Motor shell includes upper cover 11, and diaphragm-vibrating type linear motor further includes electromagnet 7, and electromagnet 7 is fixed in upper cover 11.
Specifically, there is the convex block 9 extended to 3 direction of oscillator, electromagnet 7 is fixed at the convex block 9 of upper cover 11 in upper cover 11.
The centre of the first permanent magnet 81 and the second permanent magnet 82, the first permanent magnet 81, electromagnetism is arranged in electromagnet 7
Iron 7 and 82 three of the second permanent magnet are arranged side by side.The direction of vibration of diaphragm-vibrating type linear motor is horizontal direction, and first is permanent
The pole orientation of 82 three of magnet 81, electromagnet 7 and the second permanent magnet is horizontal direction.First permanent magnet 81, electromagnetism
Iron 7,82 three of the second permanent magnet maintain gap each other.
In the state of no power, it is preferred that the first permanent magnet 81, electromagnet 7,82 three's phase of the second permanent magnet
It is identical that gap and gap are maintained between mutually.It is understood that the first permanent magnet 81, electromagnet 7, the second permanent magnet 82 3
Person symmetrically arranges on linear motor, makes oscillator 3 in the state of no power, and the power that the right and left is subject to is balanced.
For example, the magnetic pole arrangement of the first permanent magnet 81 is S-N as shown in fig. 7, from left to right, it is located in the middle electromagnetism
The magnetic pole arrangement of iron 7 can be S-N, and the magnetic pole arrangement of the second permanent magnet 82 is N-S.At this moment, the first permanent magnet 81 with forever
Heteropolar attracting between long magnet, the direction that electromagnet 7 is given to first 81 1 power F1 of permanent magnet is to the right；Electromagnet 7 with
Homopolarity mutually repels between second permanent magnet 82, electromagnet 7 be given to second another power of permanent magnet 82 F2 direction be also to
Right.At this moment oscillator 3 can move right on the whole by a power to the right.

Direction changes simultaneously, and the magnetic pole of electromagnet 7 arranges from S-N and becomes N-S.At this moment, the first permanent magnet 81 and permanent magnet
Between homopolarity mutually repel, the direction that electromagnet 7 is given to first 81 1 power F1 of permanent magnet is to the left；Electromagnet 7 is with second
Heteropolar attracting between permanent magnet 82, the direction that electromagnet 7 is given to second another power of permanent magnet 82 F2 is also to the left.This
Shi Zhenzi 3 by a power to the left, can be moved downward on the whole.
Therefore, with the variation in alternating current direction in first coil 72, the effect mutual with permanent magnet of electromagnet 7
The direction of power also changes therewith.Final drive vibrator 3 is vibrated back along linear direction.In addition, with conventional linear vibration motor
Structure compare, the application uses permanent magnet and electromagnet as power drive structure, bigger vibratory output may be implemented, tie
Structure is fairly simple, while the Qi Zhizhen time is few.
It should be noted that in other embodiments, permanent magnet can only include a permanent magnet, i.e., first is permanent
Magnet 81.First permanent magnet 81 and electromagnet 7 are arranged side by side.The direction of vibration of diaphragm-vibrating type linear motor is horizontal direction, the
The pole orientation of one permanent magnet 81 and electromagnet 7 is parallel to the direction of vibration of diaphragm-vibrating type linear motor, is horizontal direction.Cause
This, with the variation in alternating current direction in the first coil 72 of electromagnet 7, electromagnet 7 is mutual with the first permanent magnet 81
The direction of active force also change therewith.Finally also drive vibrator 3 is vibrated back along linear direction.But the program, and simultaneously
The first permanent magnet 81 is arranged to compare with the second permanent magnet 82, the driving force that oscillator 3 is subject to becomes smaller, therefore linear oscillator mould
Group seismaesthesia weakens.Meanwhile the balance of linear vibration is poor.
The present embodiment two replaces elastic slice by using vibrating diaphragm, because the damping ratio elastic slice of vibrating diaphragm is much larger, can allow linear
Motor is smaller in the amplitude variation that identical voltage drives under different frequency, is easier to control vibration sense driving, while can be big
The big dwell time for reducing Flexible element.
In addition, also permanent magnet and electromagnet is arranged side by side, the first permanent magnetic by setting permanent magnet and electromagnet
The pole orientation of iron and electromagnet is parallel to the direction of vibration of diaphragm-vibrating type linear motor；And apply in the first coil of electromagnet
Alternating current changes the both ends magnetic pole of electromagnet with the variation of current direction, permanent magnet and electromagnet it is mutual
Force direction changes with the direction of alternating current, and final drive vibrator is vibrated back along linear direction, linear with routine
The structure of vibrating motor is compared, and the application uses permanent magnet and electromagnet as power drive structure, relatively simple for structure, can be with
It realizes bigger vibratory output, the Qi Zhizhen time can also be further reduced.
Compared with the existing technology, the beneficial effects of the present invention are:
1, the present invention replaces elastic slice by using vibrating diaphragm, because the damping ratio elastic slice of vibrating diaphragm is much larger, linear motor can be allowed to exist
Identical voltage and the amplitude variation that drives under different frequency is smaller, be easier to control vibration sense driving, while can substantially reduce
