An image capturing module and an electronic apparatus according to an embodiment of the present application are described below with reference to fig. 1 to 6.

As shown in fig. 1 and 2, an image capturing module according to some embodiments of the present application includes: the lens assembly 100, the chassis 200, the flexible filter 300, the vibrator 400, and the imaging chip 500. The base 200 is connected with the lens assembly 100, the flexible optical filter 300 is arranged on the base 200, the vibrating piece 400 is arranged on the flexible optical filter 300, the vibrating piece 400 is used for driving the flexible optical filter 300 to vibrate, and the vibrating piece 400 has light transmittance. The imaging chip 500 is connected to the chassis 200, and the flexible filter 300 is located between the lens assembly 100 and the imaging chip 500.

The flexible filter 300 and the imaging chip 500 are fixed on the base 200, the flexible filter 300 is used for filtering the light received by the lens assembly 100, and the imaging chip 500 receives the light from the lens assembly 100 for analog-to-digital conversion.

The vibration member 400 can vibrate, and since the vibration member 400 is disposed on the flexible filter 300, when the vibration member 400 vibrates, the vibration member 400 can drive the flexible filter 300 to vibrate. If dust falls on the flexible optical filter 300, along with the vibration of the flexible optical filter 300, the dust falling on the flexible optical filter 300 can be driven to vibrate, so that the dust falling can be separated from the surface of the flexible optical filter 300, the purpose of dust removal is achieved, the effect of shooting is prevented from being influenced due to the fact that the dust falling stays on the flexible optical filter 300, and the problem of black clusters in shooting or video recording can be solved.

The flexible filter has the advantage of easy deformation, and the piezoelectric element 410 can drive the flexible filter to generate larger deformation, so that the dust removal effect of the flexible filter can be improved.

Because the flexible optical filter 300 is easy to deform, when the piezoelectric element 410 drives the flexible optical filter 300 to deform, the flexible optical filter 300 is not easy to break or damage, so that the damage rate of the flexible optical filter 300 can be reduced.

The vibration member 400 has light transmittance, and prevents light of the flexible filter 300 from reaching the imaging chip 500.

As shown in connection with fig. 1, 2, and 5, in some embodiments, optionally, the vibrating member 400 includes: piezoelectric element 410. Piezoelectric element 410 is located between flexible filter 300 and base 200.

When voltage acts on the piezoelectric element 410, the piezoelectric element 410 generates mechanical deformation along with the change of voltage and frequency, so that the piezoelectric element 410 generates high-frequency vibration, the flexible optical filter 300 and the piezoelectric element 410 are connected together through a dispensing process, when the piezoelectric element 410 vibrates, the flexible optical filter 300 is driven to vibrate together, and dust attached to the surface of the flexible optical filter 300 can fall off the flexible optical filter 300 due to the deformation of the flexible optical filter 300 and the high-frequency vibration.

In one possible application, the piezoelectric element 410 may be a piezoelectric ceramic or a piezoelectric crystal.

In fig. 3, when the piezoelectric element 410 and the flexible filter 300 are not in operation, as shown in fig. 4, after the piezoelectric element 410 is energized, the piezoelectric element 410 deforms and deforms together with the flexible filter 300 along the arrow direction, and the dust falling on the surface of the flexible filter 300 falls off due to the reciprocating deformation and vibration of the piezoelectric element 410.

In other embodiments, the vibration member 400 may be an ultrasonic vibrator, and uses ultrasonic waves to generate mechanical vibration, so as to drive the flexible filter 300 to generate vibration.

In some embodiments, optionally, piezoelectric element 410 comprises: the transparent piezoelectric element is attached to one side of the flexible filter 300 away from the lens assembly 100.

The transparent piezoelectric element is attached to the flexible optical filter 300, and the vibration effect of the flexible optical filter 300 can be improved by increasing the contact area between the transparent piezoelectric element and the flexible optical filter 300, so that the dust removal effect of the flexible optical filter 300 is improved.

The transparent piezoelectric member has piezoelectricity and transparency, and because the transparent piezoelectric member can transmit light, even if the transparent piezoelectric member is attached to the flexible optical filter 300, the transparent piezoelectric member can not block light of the flexible optical filter 300 from reaching the imaging chip 500, and on the basis of improving the vibration effect, the imaging effect can not be affected.

In addition, because the transparent piezoelectric piece is attached to the flexible optical filter 300, when the transparent piezoelectric piece deforms, the transparent piezoelectric piece also drives the flexible optical filter 300 to deform, so that dust on the flexible optical filter 300 moves along with the deformation of the flexible optical filter 300, and the dust is separated from the flexible optical filter 300, and the dust removing effect on the flexible optical filter 300 is further improved.

Illustratively, the transparent piezoelectric member is a transparent piezoelectric ceramic.

As shown in connection with fig. 2 and 5, in some embodiments, optionally, a through hole 210 is provided on the base 200, and a portion of the piezoelectric element 410 is disposed opposite the through hole 210.

As shown in fig. 2 and 5, in some embodiments, optionally, the base 200 is provided with a receiving groove 220, where the receiving groove 220 communicates with the through hole 210, and the piezoelectric element 410 and the flexible filter 300 are located in the receiving groove 220.

The accommodating groove 220 can also play a role in positioning and limiting the flexible optical filter 300, the flexible optical filter 300 can vibrate under the driving of the piezoelectric element 410, and the flexible optical filter 300 can be prevented from deviating from the installation position through the positioning and limiting effects of the accommodating groove 220, so that the flexible optical filter 300 can be ensured to stably realize the optical filtering function.

The accommodating groove 220 is formed on the base 200 in a machining mode, the piezoelectric element 410 and the flexible optical filter 300 can be installed in the accommodating groove 220, and the piezoelectric element 410 and the flexible optical filter 300 can be prevented from protruding out of the surface of the base 200 in the assembling mode, so that interference between the piezoelectric element 410 and the flexible optical filter 300 and other components is avoided.

When the piezoelectric element 410 drives the flexible filter 300 to vibrate, the dust on the flexible filter 300 falls, and when the dust is suspended in the space, the dust in the air can be generally considered to have positive charges, so that the dust can be electrostatically adsorbed. Through installing electrostatic adsorption assembly 600 on base 200, electrostatic adsorption assembly 600 can adsorb the dust fall for the dust fall concentrates on electrostatic adsorption assembly 600, avoids the dust fall to fall back on flexible filter 300 again, effectively prevents to cover the dust fall that can fall on the flexible filter 300.

In some embodiments, the electrostatic adsorption assemblies 600 are optionally distributed along the circumference of the flexible filter 300.

As shown in connection with fig. 5 and 6, in some embodiments, the base 200 may optionally be provided with a recess 230, and the electrostatic chuck assembly 600 is located in the recess 230.

The electrostatic adsorption assembly 600 is disposed in the recess 230, so that the electrostatic adsorption assembly 600 can adsorb dust fall into the recess 230, and the recess 230 has a certain depth, so that the dust fall is not easy to separate from the recess 230 after entering the recess 230.

As shown in fig. 5, in some embodiments, optionally, the electrostatic chuck assembly 600 includes: positive electrode 610 and negative electrode 620, positive electrode 610 and negative electrode 620 being provided on opposite side inner walls in groove 230.
