Description

Electronic device and housing

Technical Field

The utility model relates to the technical field of intelligent equipment, in particular to electronic equipment and a shell.

Background

In electronic devices such as mobile phones, an earpiece usually adopts an open rear cavity structure to achieve a stereo effect. However, such a design of the earpiece may cause a significant vibration of the battery back cover in the electronic device, affecting the feel and experience of the user.

In the related art, foam is generally used to block the movement of the air flow to reduce the vibration of the rear cover of the battery. However, determining the proper foam thickness is very challenging. If the initial state of the foam is too thin, the vibration reduction effect is not obvious; if the initial state of the foam is too thick, the battery rear cover may be jacked up along with the increase of the service time of the electronic equipment, so that the use experience of a user is affected. Accordingly, there is a need to provide an improved vibration damping structure.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

For electronic devices such as mobile phones, a certain back cavity space is usually reserved between a battery back cover and a battery in the electronic device in consideration that the battery expands with the increase of the service time of the electronic device. In order to achieve the stereo effect, an earpiece in an electronic device generally adopts an open rear cavity structure, so that the earpiece is communicated with a rear cavity space at a rear cover of a battery. However, such a design of the earpiece may cause an airflow generated when playing sound through the earpiece to move in the rear cavity space, thereby causing a battery rear cover in the electronic device to vibrate obviously, which affects the feel and experience of the user.

Regarding the case vibration phenomenon of the electronic device due to sound production, the inventors noted that the amount of vibration perceived by the user's hand is related to factors of the human body perceived frequency, in addition to the magnitude of the vibration amplitude of the battery back cover itself. Specifically, under the condition of the same vibration amplitude, in the low-frequency field, the hand perception of a user is stronger; the mid-band starts and the user's hand perception drops dramatically.

In order to reduce vibration perception of a shell by a user, the embodiment of the application provides electronic equipment. As shown in fig. 1, the electronic device includes a housing 1, a functional module 2, a earpiece 3, and a vibration damping layer 4.

Wherein the housing 1 comprises a shell plate 11. The functional module 2 is located inside the housing 1 with a gap between the functional module 2 and the shell plate 11. The earpiece 3 is provided on the housing 1, and the earpiece 3 communicates with the gap between the functional module 2 and the shell plate 11 and the external environment. The damping layer 4 is attached to the inner side of the shell plate 11 and is at least partially located between the functional module 2 and the shell plate 11. The vibration damping layer 4 is configured such that the frequency of the outgoing sound wave after passing through the vibration damping layer 4 is larger than the frequency of the incoming sound wave incident through the earpiece 3.

According to the electronic equipment provided by the utility model, the vibration reduction layer 4 attached to the inner side of the shell plate 11 can change the frequency of sound waves incident through the earphone 3, so that the vibration frequency of the vibration of the shell 1 caused by the airflow motion due to the propagation of the sound waves can be changed; and the vibration damping layer 4 is specifically used for increasing the sound wave frequency, so that the vibration frequency of the shell 1 can be close to the middle-high frequency band, and the vibration perception of the hand of a user can be relieved.

In addition, in the electronic equipment provided by the utility model, the vibration frequency of the sound wave is changed through the vibration reduction layer 4, so that resonance between the shell 1 and the sound wave can be avoided, the shell vibration of the electronic equipment caused by sound production is reduced, and further, the vibration perception of the hands of a user can be reduced.

In some embodiments, the damping layer 4 may employ an acoustically non-linear material to perform the function of varying the frequency of the sound waves.

In some embodiments, the acoustic nonlinear material may have a frequency doubling or tripling function, i.e., the frequency of the outgoing sound wave after passing through the acoustic nonlinear material is two to three times the frequency of the incoming sound wave.

In some embodiments, the acoustically nonlinear material can be prepared in the form of a coating. The coating may be applied directly to the inner side of the shell plate 11. Alternatively, the coating may be applied to an additionally provided carrier layer and the laminate structure of the coating and the carrier layer may be used as the vibration damping layer 4, wherein the carrier layer may be attached to the inner side of the shell plate 11 and the coating may be applied to the side of the carrier layer facing away from the shell plate 11.

In some embodiments, the material of the carrier layer may be consistent with the material of the shell plate 11, for example, any one of a metal material, a ceramic material, or a resin material.

In some embodiments, the acoustic nonlinear material may be prepared in liquid form and the vibration damping layer 4 may be provided as a cylindrical structure containing the acoustic nonlinear material. The cylindrical structure may be attached to the inner side of the shell plate 11.

In some embodiments, the acoustically nonlinear material can be a contrast medium. For contrast media, the greater the amplitude of the incident sound wave, the higher the efficiency of the frequency shift conversion and the more pronounced the effect. In this case, the damping layer 4 may be a contrast medium coating; alternatively, the damping layer 4 may comprise a carrier layer and a contrast medium coating; alternatively, the vibration damping layer 4 may be a cylindrical structure containing a contrast medium. In other embodiments, the acoustically nonlinear material may also employ fluorinated liquid FC-43 or a similar inert liquid with a low acoustic velocity.

In some embodiments, the vibration damping layer 4 may be adhered to the inner side of the shell plate 11 by double sided tape or other adhesive substance.

According to the electronic equipment provided by the utility model, the sound wave frequency is changed through the acoustic nonlinear material, so that the perception degree of a user on the shell vibration of the electronic equipment is reduced, compared with the situation that the foam is used for blocking the movement of the airflow to reduce the vibration of the rear cover of the battery, the electronic equipment provided by the utility model realizes the vibration reduction effect by utilizing the inherent characteristics of the material, does not need to manually consider to design the proper foam thickness, and is simpler and more practical.

In some embodiments, the electronic device may be, for example, a cell phone, tablet computer, notebook computer, desktop computer, wearable device, mobile phone, landline phone, or hearing aid, among others.

As shown in fig. 1, in an electronic device having a display function, such as a cellular phone, the electronic device may further include a display panel 6, the display panel 6 being opposed to the case 11. The shell plate 11 may be a back shell of the electronic device, and the housing 1 may further include a middle frame 12. The shell plate 11, the middle frame 12 and the display panel 6 can be surrounded to form a containing cavity, and the functional module 2 and the vibration reduction layer 4 are positioned in the containing cavity. The earpiece 3 may be provided on the center frame 12.

In some embodiments, the functional module 2 may be a battery module, which may include a battery cell 21 and an additional component 22. The add-on assembly 22 may include a battery management chip, a PCBA (Printed Circuit Board Assembl, printed circuit board), an FPC (Flexible Printed Circuit, flexible circuit board), a battery protection chip, and the like. The additional assembly 22 may be used to control and manage the battery cells 21 to achieve various functions of the battery module.

In some embodiments, the battery cell 21 may be disposed near the bottom of the electronic device and the additional component 22 may be disposed near the top of the electronic device.

In some embodiments, the earpiece 3 may be located on top of the electronic device, and proximate to the add-on component 22. Also, as shown in fig. 1, in a direction directed by the case plate 11 of the electronic device toward the display panel 6, the earpiece 3 may be closer to the display panel 6 than the vibration reduction layer 4, so that the earpiece 3 may be aligned with a gap between the vibration reduction layer 4 and the functional module 2, so that sound waves incident through the earpiece 3 do not directly enter between the vibration reduction layer 4 and the case plate 11, but cause the case plate 11 to vibrate after passing through the vibration reduction layer 4.

In some embodiments, earpiece 3 may include a sound transmission channel and electronics such as voice coil and vibrating diaphragm.

Wherein the sound transmission channel may be provided in a hole-like structure, and the sound transmission channel may penetrate through a side wall of the middle frame 12 to communicate the inside of the electronic device with the external environment.

The electronics in the earpiece 3 may be arranged inside the centre frame 12. A first cavity can be formed between the vibrating diaphragm and the middle frame 12, and the first cavity is communicated with the sound transmission channel; and the side of the diaphragm facing away from the center frame 12 may form a second cavity. When the earphone 3 plays sound, the voice coil can be electrified to make the vibrating diaphragm vibrate. The vibration of the vibrating diaphragm may effect the compression and release of air within the first and second chambers, thereby creating an airflow motion to transmit sound waves.

In some embodiments, the electronics in the earpiece 3 may be electrically connected to a PCBA or FPC in the functional module 2 to control sound playback through the functional module 2. In other words, in some embodiments, the functional module 2 may also be a component for implementing audio playback.

In some embodiments, the shell plate 11 and the middle frame 12 may be integrally formed. Alternatively, the shell plate 11 and the center 12 may be formed separately from each other and then assembled together to form the housing 1.

Considering that the area of the battery cell 21 is much larger than the area of the additional component 22, the space for the airflow movement at the corresponding area of the battery cell 21 is larger, and thus the vibration of the housing near the battery cell 21 is more intense, and in some embodiments, the front projection of the vibration reduction layer 4 on the housing plate 11 may cover the front projection of the battery cell 21 on the housing plate 11. By providing the vibration damping layer 4 near the battery cell 21, the housing vibration perceived by the user can be effectively reduced.

In some embodiments, the front projection of the damping layer 4 onto the shell plate 11 may cover the front projection of the functional module 2 onto the shell plate 11. That is, the front projection of the damping layer 4 onto the housing plate 11 may cover the front projection of the battery cells 21 onto the housing plate 11 and cover the front projection of the additional components 22 onto the housing plate 11. By providing the vibration reduction layer 4 near both the battery cell 21 and the additional component 22, the coverage area of the vibration reduction layer 4 is enlarged, and the vibration of the housing perceived by the user can be reduced more effectively.

As shown in fig. 2, the electronic device may further comprise a camera module 5. The camera module 5 may be arranged close to the top of the electronic device and close to the earpiece 3, which is also arranged on top of the electronic device. The air flow generated in the earpiece 3 flows mainly via the camera module 5 to the rear cavity formed by the housing plate 11, and thus the vibration damping layer 4 may be provided around the camera module 5 inside the housing plate 11.

In some embodiments, as shown in fig. 2, the vibration damping layer 4 may include a first region 41 and a second region 42. Wherein the first region 41 may be arranged side by side with the camera module 5 in a first direction, the second region 42 may be arranged side by side with the camera module 5 in a second direction, and the first direction is perpendicular to the second direction.

In some embodiments, the first direction may be a width direction of the electronic device and the second direction may be a length direction of the electronic device. Also, the first region 41 may correspond to a disposition region of the additional member 22, and the second region 42 may correspond to a disposition region of the battery cell 21. The area of the second region 42 may be larger than the area of the first region 41.

In some embodiments, the first region 41 and the second region 42 may be integrally formed and configured to fit the shape of the shell plate 11 and to avoid the shape of the camera module 5, such that the first region 41 and the second region 42 may be connected to each other. Alternatively, as shown in fig. 2, a certain gap may be formed between the first region 41 and the second region 42, so that the first region 41 and the second region 42 may be separately attached to the inner side of the shell 11, thereby reducing the processing difficulty.

In some embodiments, the area of the vibration damping layer 4 is not less than 60% of the area of the case plate 11 to secure the vibration damping effect of the electronic device.

In some embodiments, the thickness of the vibration damping layer 4 may be in the range of 0.3mm-1mm to avoid unstable fixation of the vibration damping layer 4 due to too small a thickness of the vibration damping layer 4 or increase in thickness of the electronic device due to too large a thickness of the vibration damping layer 4.

The embodiment of the application also provides a shell, which comprises a shell plate 11 and a vibration reduction layer 4, wherein the vibration reduction layer 4 is attached to the inner side of the shell plate 11, and the vibration reduction layer 4 is configured so that the frequency of emergent sound waves after passing through the vibration reduction layer 4 is larger than the frequency of incident sound waves.

In some embodiments, the vibration layer 4 may be made of an acoustically nonlinear material. The acoustic nonlinear material may be prepared in the form of a coating; or the coating can be coated on a carrier layer which is additionally arranged, and the laminated structure of the coating and the carrier layer is used as the vibration reduction layer 4, wherein the carrier layer can be attached to the inner side of the shell plate 11, and the coating can be coated on the side of the carrier layer, which is away from the shell plate 11; or the vibrating layer 4 may be provided as a cylindrical structure containing an acoustically non-linear material.

In other words, the damping layer 4 may be a contrast medium coating; or the damping layer 4 may comprise a carrier layer and a contrast medium coating; or the vibration damping layer 4 may be a cylindrical structure containing a contrast medium.

In some embodiments, the vibration damping layer 4 may be adhered to the inner side of the shell plate 11 by double sided tape or other adhesive substance.

In some embodiments, the area of the vibration damping layer 4 may be not less than 60% of the area of the shell plate 11, and the thickness of the vibration damping layer 4 may be 0.3mm to 1mm.
