Fig. 1 is an exploded view of a mobile device shown in accordance with an exemplary embodiment.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
A mobile device may generally include a frame, a first panel and a second panel disposed on both sides of the frame, and a piezoelectric receiver disposed on the first panel. In general, the first panel is disposed on the front surface of the frame, the second panel is typically disposed on the back surface of the frame, and the piezoelectric receiver is fixed on the first panel of the mobile device according to a method of using the piezoelectric receiver to attach to an ear of a user, which is beneficial for the piezoelectric receiver to vibrate and resonate the first panel to generate sound to an ear of a person. However, since the piezoelectric receiver resonates in all directions when vibrating, the first panel resonates, and the frame and the second panel resonate, and the vibration of the frame and the second panel may cause vibration when a user holds the receiver when receiving a call, which may reduce user experience, and may cause sound leakage to be emitted from the second panel.
Accordingly, the present disclosure provides a mobile device to solve the problem of the piezoelectric receiver of the mobile device of the related art resonating the case and the second panel of the mobile device when vibrating. The mobile device of the present disclosure is described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram illustrating a mobile device according to an exemplary embodiment. As shown in fig. 1, the mobile device of the present disclosure may include a frame 10, a first panel 20 and a second panel 30 disposed on both sides of the frame 10, and a piezoelectric receiver 40 disposed on the first panel 20, wherein the piezoelectric receiver 40 resonates with the frame 10 along a first preset direction (shown as an X direction). The frame 10 is provided with a first vibration damping device 510, and the first vibration damping device 510 vibrates in a direction opposite to the first preset direction according to the vibration parameter of the piezoelectric receiver 40, so as to counteract a resonance effect of the piezoelectric receiver 40 on the frame 10 in the first preset direction.
Optionally, the number of the first vibration dampers 510 is multiple, and the multiple first vibration dampers 510 are symmetrically disposed on the two first side walls 110 of the frame 10 along the first preset direction, so that the vibration of the frame 10 by the first vibration dampers 510 is more uniform, and the vibration damping effect is better. In the example shown in fig. 1, the number of the first vibration dampers 510 is two, and the first vibration dampers are symmetrically disposed on the two first side walls 110 of the frame 10 along the first predetermined direction.
Alternatively, the first vibration damping device 510 is a motor vibrator or a piezo-ceramic vibrator. Both motor vibrators and piezo-ceramic vibrators are active vibration damping devices, which may also be referred to as noise reducing vibration devices. The motor vibrator has the advantages of low cost but poor effect due to large occupied structure, and the pressure-sensitive ceramic vibrator has the advantages of customizable and light structure but higher cost. The user may select the type of the first vibration damping means 510 according to the actual needs.
In an embodiment of the present disclosure, the piezoelectric receiver 40 resonates with the frame 10 along a second preset direction (shown as a Y direction in the figure), and a second vibration damping device 520 is further disposed on the frame 10, where the second vibration damping device 520 vibrates along a direction opposite to the second preset direction according to the vibration parameter of the piezoelectric receiver 40, so as to counteract a resonant effect of the piezoelectric receiver 40 on the frame 10 along the second preset direction. The second preset direction is perpendicular to the first preset direction.
Optionally, the number of the second vibration dampers 520 is multiple, and the multiple second vibration dampers 520 are symmetrically disposed on the two second sidewalls 120 of the frame 10 along the second preset direction, so that the vibration is more uniform, and the reverse vibration effect is better. In the example shown in fig. 1, the number of the second vibration dampers 520 is two, and the second vibration dampers are symmetrically disposed on the two second side walls 120 of the frame 10 along the second predetermined direction.
Alternatively, the second vibration damping device 520 is a motor vibrator or a piezo-ceramic vibrator. Both motor vibrators and piezo-ceramic vibrators are active vibration damping devices, which may also be referred to as noise-reducing vibration devices. The motor vibrator has the advantages of low cost but poor effect due to large occupied structure, and the pressure-sensitive ceramic vibrator has the advantages of customizable and light structure but higher cost. The user can select the type of the second vibration damping device 520 according to actual needs.
In an embodiment of the present disclosure, the piezoelectric receiver 40 resonates with the second panel 30 along a third preset direction (shown as a Z direction), a third vibration reduction device 530 is disposed on the second panel 30, and the third vibration reduction device 530 vibrates in a direction opposite to the third preset direction according to the vibration parameter of the piezoelectric receiver 40, so as to counteract the resonant action of the piezoelectric receiver 40 on the second panel 30 along the third preset direction. The third preset direction is perpendicular to the first preset direction and the second preset direction.
Optionally, the number of the third vibration dampers 530 is plural, and the plural third vibration dampers 530 are symmetrically disposed on the second panel 30, so that the vibration is more uniform, and the reverse vibration effect is better. In the example shown in fig. 1, the number of the third vibration dampers 530 is two, and the third vibration dampers 530 are symmetrically disposed on the second panel 30, and the third vibration dampers 530 are arranged in the same direction as the piezoelectric microphones 40.
Alternatively, the third vibration damping device 530 is a motor vibrator or a piezo-ceramic vibrator. Both motor vibrators and piezo-ceramic vibrators are active vibration damping devices, which may also be referred to as noise-reducing vibration devices. The motor vibrator has the advantages of low cost but poor effect due to large occupied structure, and the pressure-sensitive ceramic vibrator has the advantages of customizable and light structure but higher cost. The user can select the type of the third vibration damping means 530 according to actual needs.
Therefore, the first vibration damping device 510 and the second vibration damping device 520 provided in the casing 10 of the mobile device of the present disclosure are mainly used to damp the resonance action of the piezoelectric microphone 40 on the casing 10 in the XY horizontal direction. The third vibration damping device 530 disposed on the second panel 30 of the mobile device is mainly used to damp the resonance action of the piezoelectric microphone 40 on the second panel 30 in the Z direction. Since the driving signal is known when the piezoelectric receiver 40 works, and the direction and amplitude of the vibration of the piezoelectric receiver are also known, the first vibration reduction device 510, the second vibration reduction device 520, and the third vibration reduction device 530 can perform opposite vibration in the XYZ direction relative to the resonant motion of the piezoelectric receiver 40 according to the vibration parameters of the piezoelectric receiver 40, so as to achieve the purpose of attenuating and canceling the additional vibration of the mobile device caused by the piezoelectric receiver 40. In addition, although the first vibration damping device 510, the second vibration damping device 520, and the third vibration damping device 530 do not affect the sound emission of the piezoelectric receiver 40 to the vibration of the first panel 20, unnecessary extra resonance of the housing 10 and the second panel 30 can be suppressed and attenuated, and finally, the user experience can be improved. In addition, when the extra vibration is reduced, the Signal-to-Noise Ratio (SNR) of the piezoelectric microphone 40 is improved, the Noise of the extra vibration is reduced, and the experience of the user holding the device is improved.
In practical applications, the method for using the mobile device of the present disclosure may include the following steps:

In step S103, a third vibration damping device 530 is disposed on the second panel 30, and the third vibration damping device 530 vibrates in a direction opposite to the third preset direction according to the vibration parameter of the piezoelectric receiver 40, so as to counteract the resonance effect of the piezoelectric receiver 40 on the second panel 30 in the third preset direction.
In one example, when a user uses the mobile device, the first panel is attached to the ear, and the piezoelectric receiver vibrates to resonate the first panel and to generate sound to the ear, and simultaneously resonates the housing and the second panel. At the moment, the first vibration reduction device arranged on the frame body vibrates in the direction opposite to the first preset direction according to the vibration parameters of the piezoelectric receiver, so that the resonance effect of the piezoelectric receiver on the frame body in the first preset direction is counteracted. And vibrating in the direction opposite to the second preset direction according to the vibration parameters of the piezoelectric receiver through a second vibration damping device arranged on the frame body so as to counteract the resonance effect of the piezoelectric receiver on the frame body in the second preset direction. The third vibration reduction device arranged on the second panel vibrates in the direction opposite to the third preset direction according to the vibration parameters of the piezoelectric receiver so as to counteract the resonance effect of the piezoelectric receiver on the second panel in the third preset direction, so that the purpose of attenuating and counteracting the additional vibration caused by the piezoelectric receiver on the mobile equipment is achieved, and the experience of a user for holding the equipment is improved.
