[Prior Art] In portable, especially handheld electronic devices, such as mobile phones, tablets, handheld game consoles, and MP4 players, speakers are usually built in to satisfy the user's enjoyment of playing music or playing games. . In order to ensure better sound, the sound hole of the speaker is preferably placed on the front side of the electronic device, that is, the side on which the display screen is provided. On the front side of the handheld electronic device, the display area needs to be as large as possible, and usually some buttons are set. Due to the size of the product, the sound hole of the speaker will occupy the area of the display screen and the button. Therefore, some manufacturers set the sound hole of the speaker on the side of the palm-type electronic device, even at the lower corner (as shown in FIG. 1), the speaker sounding mode is side sounding, and one sound pressure is lost in the sound cavity. At the same time, when the sound hole is out, the medium 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 is blocked, which further causes the sound pressure to drop. When it is placed on the back side, there is still a problem that the sound hole is blocked when the electronic device is laid flat. SUMMARY OF THE INVENTION In view of the above, the present invention is directed to a portable electronic device that does not affect the display screen and button settings and ensures sound effects.

Referring to FIG. 4 together, the rear cover 12 includes a substantially rectangular rear plate body 124 and a side wall 125 extending from the periphery of the rear plate body 124 toward the plate 11. The flat portion 126 is located in the middle of the rear plate body 124, and the two inclined portions 121 are respectively located on opposite sides of the flat portion 126, and are located at a position where the casing 1 is abutting to the periphery. The inclined portion 121 is formed by the obliquely bent sides of the straight portion 126 to form ' and is lifted upward with respect to the straight portion 126. The angle between the inclined portion 121 and the front surface of the casing 1 thereof is preferably selected from 3 to 60 degrees. As shown in FIG. 5, when the casing 10 is horizontally upward in the display area 111, when the ❹ is placed on a horizontal plane 3', the inclined portion 21 is higher than the flat portion 126 of the casing 10, thereby An outwardly expanding open space 31 is formed between the inclined portion ι21 and the horizontal plane 3〇 to facilitate the outward propagation of the sound transmitted from the sound hole 122. [0013] The β-tilt portion 121 may be a plane or a curved surface, and the sound hole 丨2 2 is centrally disposed along a straight extending direction (ie, a longitudinal direction) of the inclined portion 121. In this embodiment, the inclined portion 121 is a flat surface, and the sound emitting holes 122 are distributed in the rectangular portion of the inclined portion 121. In other embodiments, the sound holes 122 may also be in other forms, such as a circular array, a square array. 000137551 Form No. A0101 Page 5 of 17 0992065432-0 201221011 [0016] [0016] [0016] The inner wall of the rear plate body 124 extends perpendicularly to each set of sound holes 22 to form an annular wall 127, The wall 127 and the rear plate body 124 are enclosed to form the sound cavity 123. The sound chamber 123 is substantially in the shape of a disk and includes a circular cavity and a rectangular cavity on the side of the circular cavity. The opening area of each set of sound holes 122 is located in the area of the casing 1 facing the sound chamber 123, and the aperture ratio of each group of sound holes 122 (ie, the total area of the sound hole 122 of the group and the sound hole 122) The ratio of the opening area is more than 2%. Each speaker 20 is correspondingly disposed in a sound chamber 123, and the front surface of the speaker 2 面对 faces the area where the sound hole 122 is located on the casing 10, that is, the sound of the speaker 2 is sounded directly (positive sound). . When the speaker 2 is operated, the sound emitted by the speaker 2 is led out through the sound hole 122 and spreads obliquely outward, wherein the sound emitted by the speaker 2 is transmitted through the sound hole 122 and the sound intensity is the largest ( As shown by the arrow in Fig. 5), it forms an acute angle with the plane of the display area ιη, that is, it is not parallel or perpendicular. In the portable electronic device 100, the housing 10 has a symmetrical structure, and the back inclined portion 121 is symmetrically disposed. The two sets of sound holes 22 are symmetrically disposed on the back of the two inclined portions 12 on the housing. It is also possible to provide four inclined portions 12 at a position adjacent to the sin of the casing 10, and a set of sound holes 122 are formed in each of the inclined portions 121, that is, four sets of sound holes 122 are disposed on the back surface of the casing 1〇. 'Correspondingly, a speaker 20 is disposed in the casing 1 for each set of sound holes 122. = In the portable electronic device 100, since the sound hole (2) is provided on the casing_moon surface, the speaker 20 can be set to sound directly (positive sound) with respect to the sound hole 122, relative to the side sound. Mode speaker, the speaker 20 pairs of sound medium and high frequency components (5KHz ~ 20KHz) with 099137551 Form No. A0101 Page 6 / 17 pages 0992065432-0 201221011 have higher fidelity, thus meeting the user Enjoy audiovisual enjoyment while listening to music or playing games. [0017] The improvement of the external structure of the casing and the adjustment of the sound hole of the present invention provide a means for the operator to effectively avoid sound shielding and ensure sound pressure, and the structural design can also change the sound of the speaker accordingly. Ways to ensure sound effects. C〇〇18] Red, the invention complies with the invention patent requirements, and patents are filed according to law.
