Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Please refer to figure 1 , is a schematic structural diagram of Embodiment 1 of the electronic device of the present invention. The electronic device 200 includes a frame 1 with a receiving space, a screen 2 assembled in the frame 1 , and a vibration motor 4 fixed on the frame 1 and used to drive the frame 1 to vibrate. The vibration direction of the vibration motor 4 is perpendicular to the plane where the screen 2 is located.

[0030] The frame 1 includes a rear cover 11 , a frame 12 surrounding the rear cover 11 , and a middle frame 13 accommodated in the receiving space and fixed to the frame 12 . In this embodiment, the middle frame 13 is integrally formed with the frame 12 . Of course, the middle frame 13 and the frame 12 can also be arranged separately.

[0031] The electronic device 200 further includes a glass panel 22 fixed on the f...

Abstract

Provided is an electronic device, comprising a framework, a screen matched with the framework to form an accommodation space and a vibration motor that is accommodated in the accommodation space and fixedly connected with the framework. The vibration motor is used to drive the framework to vibrate, and to drive the screen to vibrate and to produce sound. The vibration motor comprises a case, a vibrator and a stator accommodated in the case, and an elastomer by which the vibrator is suspended inside the case. One of the vibrator and the stator comprises a magnetic circuit system and the other comprises a coil. The vibration motor vibrates along the direction perpendicular to a plane of the screen. The vibration motor of the electronic device provided in the invention is fixed to the framework. The vibration motor vibrates and drives the framework to vibrate, thereby driving the screen to vibrate and to produce sound with a good sounding performance.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of mobile electronic equipment, in particular to an electronic equipment. [0003] 【Background technique】 [0004] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile device. At present, the functions of mobile phones are extremely diverse, one of which is high-quality call and music playback functions, and the sound generating device in the mobile phone is one of the necessary conditions for realizing this high-quality call and music playback functions. [0005] In the related art, the screen sounder of the mobile phone usually drives the vibration motor to directly drive the screen to vibrate and produce sound by inputting an audio signal. The output sound quality of this driving method is poor, and the driving force of the vibration motor is small, which affects t...
