Problems solved by technology

[0003] On the front of the handheld electronic device, the display area needs to be as large as possible, and some buttons are usually set up. Due to the limitation of the product size, the sound hole of the speaker will occupy the area of ​​the display screen and the buttons.
Therefore, some operators set the sound outlet of the speaker on the side of the handheld electronic device, or even at the corner below (such as figure 1 As shown), the sound output mode of the speaker is side output sound, and the sound pressure will be lost in the sound cavity. At the same time, when the sound is output through the sound output hole, the middle and high frequency components are not rich, which affects the user's audio-visual enjoyment
At the same time, when the user holds the electronic device, the sound hole will be covered, which will further reduce the sound pressure.
However, when it is installed on the back, there is still the problem of covering the sound outlet when the electronic device is placed flat and used

Abstract

The invention relates to a portable electronic device which comprises a flat-shape shell. A right side of the shell is provided with a display area and a back side forms an inclined portion which is provided with a sound hole. A loudspeaker, which corresponds with the sound hole, is arranged in the shell. In the invention, under a condition of not influencing an electronic device display screen and button setting, sound pressure decrease caused by shielding of the sound during a usage process can be avoided and a hearer can obtain a good audio-visual enjoyment.

Description

technical field [0001] The invention relates to an electronic device, in particular to a portable electronic device. Background technique [0002] In portable, especially handheld electronic devices, such as mobile phones, tablet computers, handheld game consoles and MP4 players, built-in speakers are usually built in to satisfy users' audio-visual enjoyment when playing music or playing games. In order to ensure a better sound effect, the sound outlet of the speaker is preferably arranged on the front side of the electronic device, that is, the side with the display screen. [0003] On the front of the handheld electronic device, the display area needs to be as large as possible, and some buttons are usually provided. Due to the limitation of the product size, the sound outlet of the speaker will occupy the area of ​​the display screen and the buttons. Therefore, some operators set the sound outlet of the speaker on the side of the handheld electronic device, or even at th...
