Problems solved by technology

The exciter is arranged on the middle plate and is located between the back cover and the middle plate; in the above two patent documents, a single exciter is used to drive the screen to produce sound, and there are the following main problems, which are: There is a narrow frequency band (mainly because the stiffness of the screen is relatively high, so the low-frequency response is relatively poor) and the screen has strong resonance, which affects the user's experience when holding it. The stereo function cannot be realized.
[0004] The prior art also discloses a technical solution in which multiple vibration sources drive the screen to produce sound. For example, patent WO2019 / 191953A1 discloses a terminal device, including: a screen component, at least one vibration source, a device middle frame, a circuit board and a back cover; , the screen assembly is installed on the front of the middle frame of the device, the circuit board is installed on the front of the middle frame of the device and is located between the screen assembly and the middle frame of the device, and the back cover is installed on the The back of the middle frame of the device; the vibration source is installed on the back of the screen assembly, and the vibration source is used to drive the screen assembly to vibrate and make sound in a direction perpendicular to the screen assembly, but the above-mentioned patent The screen sound generating devices are all concentrated behind the screen components, which have a strong sense of shock and affect the user experience, and their stereo effect is poor, and the frequency response is narrow

Embodiment 1

[0069]Such asFigure 1-3 And 4A-4C, in this embodiment, a screen sounding device applied to a mobile phone includes a front panel 1, a block and a rear cover 3, the front panel 1 is fixed above, and then The cover 3 is fixed below the middle frame, the middle frame including the medium plate 2 and the frame 4, the outer plate, the front panel, the front frame, and the medium plate to enclose a closed space; the rear cover, The border and the medium plate are enclosed in a closed space; two front exciters 5 are provided between the front panels and the medium plates, and the two front exciters 5 are respectively fixed to the intermediate of the front and rear sides of the front panel 1. Position, one postal exciter 6 is provided between the back cover and the medium plate, wherein the rear excitation 6 is fixed to the back cover 3.

[0070]Among them, the front panel 1 of the present invention is used as the screen, and the battery 9 and the PCB plate 8 are provided in the rear cover, an...

Embodiment 2

[0077]Such asFigure 8-10 As shown, the present embodiment is different from the mounting portion 7 of the first embodiment to the back cover, the remainder, the rear cover, the mounting portion, wherein the mounting portion in the present embodiment is a square structure, the mounting portion 7 The periphery surround corrugated structure 14, the corrugated structure 14 is a continuously disposed rib structure, wherein the adjacent arrangement of the rib structure is opposite.

Embodiment 3

[0079]Such asFigure 11-13As shown, the present embodiment is different from the back cover of the first embodiment, wherein the rear cover in the present embodiment is two layers, and specifically includes the outer surface plate 15 and the inner surface plate 16; the outer surface plate 15 is used as a mobile phone The role of the panel, the outer panel 15 is not opened at a position corresponding to the post-installation of the rear exciter 6, the outer surface plate 15 and the inner surface panel 16 are identical, and the inner surface plate 16 is adjacent to the intermediate position. With through holes 17, the through hole 17 is a rectangular, and the rear exciter 6 is directly bonded to the outer surface panel 15 through the through hole 17, which can cause the vibration range to be limited to the area of ​​the through hole 17. Inside, the outer surface plate 15 and the inner surface plate 16 are glued.

Abstract

The invention relates to the technical field of electronic equipment, and specifically provides a screen sound generating device, method, storage medium and electronic device. The device provided by the present invention includes a front panel, a middle frame and a rear cover, the front panel is fixed above the middle frame, the rear cover is fixed below the middle frame, the middle frame includes a frame and a middle plate, and the front panel There are two front exciters arranged between the middle plate and the two front exciters respectively fixed in the middle positions of the left and right sides of the front panel, and one rear exciter is arranged between the rear cover and the middle plate exciter. Wider frequency response and stereo function are achieved through the frequency division combination of the front / rear exciter, and at the same time, the structural optimization of the rear cover avoids the tactile interference caused by the surface vibration of the terminal device to the user.

Description

Technical field[0001]The present invention belongs to the technical field of electronic devices, and in particular, the present invention relates to screen sounding devices, methods, storage media, and electronic devices.Background technique[0002]The current development trend of mobile phones is that the screen accounts for growing, and finally develops to the full screen. The head of the camera is always an impact on the screen space. If you can completely cancel the handset hole, on the screen The increase in the proportion will have a great help.[0003]The principle of the screen vocal is to be installed behind a tablet with an exciter that pushes the flat sound vibration through the exciter, generating a sound signal, the source of the exciter, is not limited to, the electromagnet drive, linear motor, or coil-magnet drive structure, When the actuator is installed behind the mobile phone panel (screen), drive the exciter with an audio signal, can drive the screen vibration, by adj...
