本申请涉及电子产品技术领域,尤其涉及一种屏幕结构及电子设备。The present application relates to the technical field of electronic products, and in particular, to a screen structure and electronic equipment.
屏幕发声的技术原理是利用振动原件推动屏幕振动发出声音。例如:共振式的屏幕发声方案,是将一个具有振动特性的器件贴在屏幕下方或整机中框上,器件在工作时候产生振动,最终带动屏幕振动发声;又例如:直推式的屏幕发声方案,器件主要由两部分构成,其中一部分直接贴在屏幕上,另一部分固定于中框上,当器件工作时,两部分会产生相互作用的引力或者斥力,由此来推动屏幕振动发声,其相比于共振式的屏幕发声方案转换效率有提高。但是,目前的屏幕发声方案由于电子设备内的堆叠空间受限,均只能堆叠于屏幕下方的某个空间,所以在推动屏幕振动发声时效率较低,并且由于空间受限只能将器件布局与屏幕的较小的区域内,器件在屏幕上的应力都会比较大,在整机受力时,屏幕在与器件耦合的部分会形成明显的应力,有比较大的可靠性风险。The technical principle of the screen sound is to use the vibration element to push the screen to vibrate to produce sound. For example, the resonant screen sounding scheme is to attach a device with vibration characteristics to the bottom of the screen or on the middle frame of the whole machine. The device vibrates during operation, and finally drives the screen to vibrate and sound; another example: direct push screen sound In the scheme, the device is mainly composed of two parts, one part is directly attached to the screen, and the other part is fixed on the middle frame. When the device is working, the two parts will generate mutual attraction or repulsion, thereby pushing the screen to vibrate and sound, which Compared with the resonant screen sound generation scheme, the conversion efficiency is improved. However, due to the limited stacking space in the electronic device, the current screen sound generation solutions can only be stacked in a certain space below the screen, so the efficiency of pushing the screen to vibrate and sound is low, and due to the limited space, the device can only be laid out. Compared with the smaller area of the screen, the stress of the device on the screen will be relatively large. When the whole machine is stressed, the screen will form obvious stress in the part coupled with the device, which has a relatively large reliability risk.

本申请实施例中的电子设备包括如上所述的屏幕结构,能够节省空间,并且由于振动结构呈板状,也便于电子设备的内部空间布局,并有利于提高屏幕振动发声时效率,也有利于减小屏幕上的应力,从而提高可靠性。The electronic device in the embodiment of the present application includes the above-mentioned screen structure, which can save space, and because the vibration structure is in the shape of a plate, it is also convenient for the internal space layout of the electronic device, and is beneficial to improve the efficiency when the screen vibrates and emits sound. Reduces stress on the screen, improving reliability.
可选地,所述电子设备还包括:控制器,所述控制器与所述振动组件3连接;所述控制器用于输出激励信号至所述振动组件3;所述振动组件3在所述激励信号的作用下发生振动,并带动所述屏幕组件1振动发声。Optionally, the electronic device further includes: a controller, which is connected to the vibration component 3; the controller is used to output an excitation signal to the vibration component 3; Vibration occurs under the action of the signal, and drives the screen assembly 1 to vibrate and emit sound.
例如:控制器可以向振动组件3中的连接臂32输出激励信号,而连接臂32作为整个结构中的动力部分,当通入激励信号时,由于压电效应,连接臂32会上下振动,带动振动片31上下运动,从而对屏幕组件1产生推拉力,推拉力作用于屏幕组件1会引起屏幕组件1的振动,从而发出声音。For example, the controller can output an excitation signal to the connecting arm 32 in the vibration component 3, and the connecting arm 32 is the power part in the whole structure. When the excitation signal is input, the connecting arm 32 will vibrate up and down due to the piezoelectric effect, driving the The vibrating piece 31 moves up and down, thereby generating a push-pull force on the screen assembly 1, and the push-pull force acting on the screen assembly 1 will cause the screen assembly 1 to vibrate, thereby producing sound.

Wherein, the vibration parameters may include the amplitude, phase, frequency, etc. of the vibration.
又例如:每个振动组件3可以通过单独的控制电路控制,即单独的控制电路可以向其对应的振动组件3分别输出激励信号,以实现多个振动组件3能够单独振动;或者单独的控制电路可以向其对应的振动组件3输出相同或不同的激励信号,以实现多个振动组件3能够同时振动。Another example: each vibration component 3 can be controlled by a separate control circuit, that is, the separate control circuit can output excitation signals to its corresponding vibration components 3 respectively, so as to realize that multiple vibration components 3 can vibrate independently; or a separate control circuit The same or different excitation signals can be output to the corresponding vibration components 3, so that multiple vibration components 3 can vibrate at the same time.
该实施例中,由于多个振动组件3之间间隔设置,即如图2所示的基板2上的多个通孔21之间相互隔离。这样,当基板2与屏幕组件1耦合后,相当于将屏幕组件1被划分为多个独立区域,每个独立区域分别与对应的振动片31耦合,当振动片31振动时单独推动其对应的独立区域振动,而不会影响到其他区域,从而可以避免造成相互之间的干扰,从而可以实现较好的声学效果。In this embodiment, since the plurality of vibration components 3 are arranged at intervals, that is, the plurality of through holes 21 on the substrate 2 as shown in FIG. 2 are isolated from each other. In this way, when the substrate 2 is coupled with the screen assembly 1, it is equivalent to dividing the screen assembly 1 into a plurality of independent areas, each independent area is respectively coupled with the corresponding vibrating piece 31, and when the vibrating piece 31 vibrates, its corresponding Independent areas vibrate without affecting other areas, so as to avoid mutual interference and achieve better acoustic effects.
可选地,当需要较好的低频时,可以控制所有的振动片31同相位开始振 动,这样屏幕组件1推动空气的体积可以达到最大,能够达到较好的低频效果;当需要特定的声场需求时,如3维(3D)声音效果,可以控制不同振动片31的振幅和相位,从而达到特定的声场需求。Optionally, when a better low frequency is required, all the vibrating sheets 31 can be controlled to start vibrating in the same phase, so that the volume of the air pushed by the screen assembly 1 can be maximized, and a better low frequency effect can be achieved; when specific sound field requirements are required For example, 3-dimensional (3D) sound effects, the amplitude and phase of different vibrating pieces 31 can be controlled to achieve specific sound field requirements.
具体还可以根据不同的应用要求,对振动片31之间的间距作调整,以达到特殊的阵列要求。如:为了让该振动结构在屏幕组件1上发出符合超声波定向发声的指向性要求,可以根据超声波定向发声的声压级要求、指向角要求等特性,布局振动片31之间的间距,同时匹配电路的控制调整振动片31的相位,用以达到需要的声场需求,本申请实施例不以此为限。Specifically, according to different application requirements, the spacing between the vibrating sheets 31 can be adjusted to meet special array requirements. For example, in order to make the vibration structure emit on the screen assembly 1 to meet the directivity requirements of ultrasonic directional sounding, the spacing between the vibrating sheets 31 can be arranged according to the sound pressure level requirements, pointing angle requirements and other characteristics of ultrasonic directional sounding, and at the same time matching The control of the circuit adjusts the phase of the vibrating piece 31 to meet the required sound field requirements, and the embodiment of the present application is not limited to this.
