1. Technical Field
The present disclosure relates to electronic devices, and particularly to an electronic device comprising a signal receiving unit.
2. Description of Related Art
Electronic devices, such as DVD players, may include a housing having a bottom plate and a front sidewall slantingly extending from a rim of the bottom wall, a sensor window cover secured to the front sidewall, a circuit board received in the housing and parallel to the bottom wall, and a signal receiving unit perpendicularly secured to the circuit board and corresponding to the sensor window. However, the sensor window cover is generally coplanar with front sidewall and is slanted relative to the bottom plate. When the signal receiving unit is perpendicularly secured to the circuit board, the signal receiving unit may maintain a greater distance with the sensor window cover, which may result in a weaker receiving capability of the signal receiving unit.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the four views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

The sensor window cover 20 is secured to the front sidewall 102 and maintains the angle α with the bottom wall 101. In the embodiment, the sensor window cover 20 is made of polymethyl methacrylate, and is coplanar with the front sidewall 102.
The circuit board 30 is substantially rectangular, and is arranged parallel to the bottom wall 110. The circuit board 30 defines two fixing holes 310. The fixing holes 310 are arranged at an end of the circuit board 30 adjacent to the front sidewall 102 and correspond to the signal receiving unit 20.
The signal receiving unit 40 is secured to an end of the circuit board 30 adjacent to the front sidewall 102 and corresponds to the sensor window cover 20. The signal receiving unit 40 is electrically connected to the circuit board by a plurality of pins 60. In the embodiment, the pins 60 is conductive and is stiff enough to support the signal receiving unit 40 in the circuit board 30. The signal receiving unit 40 includes a main body 410 and a receiving portion 420 secured to the main body 410. The receiving portion 420 is substantially semispherical and corresponds to the sensor window cover 20.

The supporting mechanism 50 includes a base 510, a holding member 520 protruding from an end of the base 510 adjacent to the sensor window cover 20, two abutting members 530 secured to the base 510 and parallel with each other, and two fixing posts 540 secured to a surface of the base 510 opposite to the holding member 520.
The base 510 includes a top surface 511, a bottom surface 512 opposite to the top surface 511, a front end 513, and a rear end 514 opposite to the front end 513. The top surface 511 define a receiving groove 515. The bottom of the receiving groove 515 defines three through holes 517. The through holes 517 are spaced from each other and are aligned parallel to and adjacent to the rear end 514. The bottom of the receiving groove 515 further defines an opening 516. The opening 516 is arranged adjacent to the front end 513.
An end of the holding member 520 away from the top surface 511 define a recess 521 for receiving the main body 410 of the signal receiving unit 40. Each abutting member 530 perpendicularly extends from the bottom of the receiving groove 515 and perpendicularly connects with the rear end 514. Each abutting member 530 is arranged between two adjacent through holes 517. An end of each abutting member 530 bents toward the holding member 520 to from a cantilever 532. The projection of the cantilevers 532 to the bottom of the receiving groove 515 extend into the opening 516. Each cantilever 532 defines an abutting surface 534. The abutting surface 534 extends in a direction parallel to the front sidewall 102. In the embodiment, when the supporting mechanism 50 is secured to the circuit board 30, the abutting surface 534 maintains the angle α with the bottom wall 101. The abutting surface 534 cooperates with the recess 521 of the holding member 520 to define a holding space 536 communicating the opening 516. The fixing posts 540 protrude from the rear surface 512 and are arranged adjacent to the rear end 514. The fixing posts 540 correspond to and are received in the fixing holes 310 respectively.
