Problems solved by technology

[0003] However, since this structure for controlling the power off of the backlight of the display screen must cooperate with the Hall sensor installed on the base and an additional magnet is installed on the corresponding position of the flip cover, it increases the cost and increases the number of components in the electronic product. Quantity and the weight of the flip cover, when designing the flip cover, it is necessary to reserve a space for installing the magnet, thus increasing the complexity of the manufacturing design and the difficulty of assembly

Embodiment Construction

[0033] Please refer to figure 1 A foldable electronic device provided by an embodiment of the present invention includes a relatively foldable first part and a second part, and the foldable electronic device includes a clamshell mobile phone, a notebook, a player (DVD, Digital Versatile Disk) with a display screen. ), etc., here we take a DVD player as an example to illustrate. The DVD 100 includes a foldable first part as a flip cover 10 and a second part as a body 20 , the flip cover 10 and the body 20 are pivotally connected so that they can be folded or unfolded relative to each other, so that the DVD 100 is closed or opened accordingly.

[0034] The flip cover 10 includes a casing 12 , a display screen 16 located on one side of the casing 12 , and a speaker 14 installed in the casing 12 . The speaker 14 is provided with a magnet 141 and a coil (not shown in the figure), and the magnet 141 provides a magnetic field for the speaker 14, so that the speaker 14 emits sound un...

Abstract

The invention discloses an electronic device. The electronic device comprises a first part and a second part which can be folded oppositely, wherein the first part and the second part are connected in a pivoting way; a Hall sensor is accommodated in the first part; a loudspeaker is arranged at the place, corresponding to the Hall sensor, in the second part; a magnetic element is arranged in the loudspeaker; and the Hall sensor senses the folding or unfolding state of the first part relative to the second part in the way of sensing the state of the relative position of a magnet so as to output different control signals to control the connection or disconnection of a power supply of the electronic device. Therefore, the magnet arranged outside the Hall sensor is saved, the element is saved, and a structure designed for fixing the element is saved.

Description

technical field [0001] The invention relates to an electronic device, in particular to a foldable electronic device. Background technique [0002] At present, foldable electronic products such as mobile phones, notebooks, and players with display screens (DVD, Digital Versatile Disc) have become very important tools in people's daily work and life, and are widely used in various fields. The foldable electronic product usually includes a main body and a flip cover pivotally connected with the main body and having a display screen. In order to save electric energy, a control structure capable of controlling the power of the backlight of the display screen to be turned off is usually provided between the body and the flip cover. Take a DVD with a display screen as an example. In the design of the DVD, there is usually a Hall sensor on the body, and a magnet is provided on the cover corresponding to the Hall element. When the DVD cover is closed, the Hall sensor is affected. T...
