Problems solved by technology

Since the sound outlet of the speaker will occupy a certain area, if the size of the display screen is large, it is impossible to set up a sound outlet on the front of the handheld electronic device.
Some operators set the sound outlet of the speaker on the side of the handheld electronic device. However, when the user holds the electronic device, it is easy to cover the sound outlet, resulting in a decrease in sound quality.
When it is arranged on the back of the electronic device, although the user is not easy to touch the sound hole, when the electronic device is placed flat on a support (such as a desktop), the sound hole will be blocked due to the blocking of the support. Problems causing sound quality degradation

Abstract

The invention discloses a portable electronic device. The device comprises a housing; the front surface of the housing is provided with a display area; the back surface of the housing is provided with sound holes; loudspeakers are arranged at positions, which are opposite to the sound holes, inside the housing; the back surface of the housing comprises a contact surface which can be contacted with a support object, and sound surfaces provided with the sound holes; the sound surfaces are recessed towards the display area relative to the contact surface so as to form grooves at the back surface of the housing; the grooves are communicated with the outside environment at the lateral side of the portable electronic device; and the sound emitted by the loudspeakers penetrates the sound holes and the grooves and is transmitted to outer environment. When the portable electronic device is placed on the support object, the sound holes are not shielded so that sound quality is ensured.

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, a display screen is usually arranged, and some buttons for operation are arranged near the screen. Since the sound outlet of the speaker will occupy a certain area, if the size of the display screen is large, it is impossible to reserve a redundant position for the sound outlet on the front of the handheld electronic device. Some operators arrang...
