Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Electronic device 100 according to an embodiment of the present invention is described below with reference to Fig. 1-Fig. 2.
As Figure 1-Figure 2, electronic device 100 according to an embodiment of the present invention, comprising: mainboard 2, shell 1 and driver 3。
Specifically, mainboard 2 is located in shell 1, shell 1 includes the pars stridulans 12 that flexible deformation can occur, and driver 3 is set It is electrically connected in shell 1 and with mainboard 2, driver 3 is connected to drive the vibration of pars stridulans 12 and sounding with pars stridulans 12.Wherein, Driver 3 can convert the electrical signal to mechanical oscillation.Driver 3 includes vibrating elements, and vibrating elements is connected with pars stridulans 12, Driver 3 receives different electric signals, and the voltage or electric current of input actuator 3 are also just different, so that the vibration of driver 3 Element generates different vibrations.When vibrating elements vibrates, pars stridulans 12 can be driven to vibrate, to push external gas Body generates sound.
When user plays the files such as video, audio using electronic device 100, driver 3 according to audio signal, (believe by audio Number essence is exactly electric signal) variation generate corresponding vibration, and the pars stridulans 12 on shell 1 is driven to vibrate and elastic change occurs Shape, pars stridulans 12 can produce the microvibration of micron level on the thickness direction of shell 1, so that external gas be pushed to produce Raw sound (referring to Fig. 2).
Optionally, vibrating elements can be electromagnetic vibration element or piezoelectric type vibration element.For example, vibrating elements is Piezoelectric ceramics part.
Optionally, pars stridulans 12 can be plastic parts.As a result, pars stridulans 12 have preferable elastic deformability.
Optionally, in the case where guaranteeing sounding effect, the difference of the hardness of the other parts of pars stridulans 12 and shell 1 can With the smaller of setting, thus user can weaken user and perceive different piece on shell 1 in normal use electronic device 100 Difference of hardness paresthesia, promote the usage experience of user.
Electronic device 100 according to an embodiment of the present invention, by the hair that a part of shell 1 is arranged to elastically deformable Part 12, while being connected with pars stridulans 12 by the driver 3 of setting to drive the vibration of pars stridulans 12 and sounding, without in shell Sound outlet hole is set on 1, so that the appearance of electronic device 100 has better integrality, and waterproof performance can be improved, while Screen sounding bring vibratory sensation is avoided, user is not influenced and touches the experience of screen, and solve user's both hands transverse screen and hold Firmly electronic device 100 leads to user's pain spot problem of bottom loudspeaker audio difference, and chicken, king's honor are eaten in especially both hands transverse screen object for appreciation Etc. mainstreams hand trip.
According to some embodiments of the present invention, shell 1 includes the first sub- shell 11 and the second sub- shell being connected with each other, the The hardness of one sub- shell 11 is greater than the hardness of the second sub- shell, and the second sub- shell constitutes pars stridulans 12.As a result, shell 1 Structure is simple.First sub- shell 11 and the second sub- shell can be glued or the second sub- shell is directly injection-moulded in the first sub- shell On 11.Optionally, the first sub- shell 11 and the second sub- shell are plastic parts, alternatively, the first sub- shell 11 is metalwork and the Two sub- shells are plastic parts.
Optionally, the length direction (up and down direction in referring to Fig.1) of the first sub- shell 11 and the second sub- shell in shell 1 Upper arrangement.For example, in the example of fig. 1, the first sub- shell 11 is two, the second sub- shell be located at two the first sub- shells 11 it Between.Thus, it is possible to guarantee the overall structural strength of shell 1, while the middle part of the neighbouring complete machine of the second sub- shell is arranged, It can prevent from holding pars stridulans when hand-hold electronic device 100 and influencing sounding.
Optionally, the first sub- shell 11 and the second sub- shell can also be on the width direction (left sides in referring to Fig.1 of shell 1 Right direction) on arrange.
According to some embodiments of the present invention, referring to Fig.1, pars stridulans 12 are arranged adjacent to the upper end of shell 1.It as a result, will hair The region that user will not often hold is arranged in part, can reduce external disturbance, can be better protected from hand-hold electronic device Pars stridulans are held when 100 and influence sounding, while without the vibratory sensation of screen sounding, do not influence the experience that user touches screen.
It should be noted that when " upper and lower, left and right " described herein are relative to user's hand-hold electronic device 100 For orientation.For example, when user holds mobile phone, the direction of 4 face user of display screen is when electronic device 100 is mobile phone Before, the left and right sides of user is left and right directions, is upper far from the part that user holds under the part that user holds is.
According to some embodiments of the present invention, the area of the outer surface of pars stridulans 12 is S1, total face of the outer surface of shell 1 Product is S2, and described S1, S2 meet: 1/3≤S1/S2≤1/2.As a result, pars stridulans 12 have biggish sounding area, guarantee Sound effect, while guaranteeing the overall structural strength of shell 1.
According to some embodiments of the present invention, shell 1 includes: rigid backbone, and rigid backbone can be metallic framework, sounding Portion 12 is coated in rigid backbone, and the peripheral part of pars stridulans 12 can be fixedly connected with rigid backbone.As a result, pars stridulans 12 have biggish area, further improve sounding effect.
Illustratively, the electronic device 100 of the application can be mobile or portable and execute the various types of of wireless communication Any one of computer system device of type (only illustratively shows a kind of form) in Fig. 1.Specifically, electronic device 100 can be mobile phone or smart phone (for example, being based on iPhone TM, the phone based on Android TM), portable game Play equipment (such as Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), laptop computer, PDA, portable Internet appliance, music player and data storage device, other handheld devices with And wrist-watch, In-Ear Headphones, pendant, headphone etc., electronic device 100 can also be other wearable devices (for example, such as electronic glasses, electronics clothes, electronics bracelet, electronics necklace, electronics are tatooed, the head of electronic equipment or smartwatch Wear formula equipment (HMD)).
