Description of the invention: - Technical field to which the invention pertains The present invention relates to an electronic device, and more particularly to an electronic device having a sound module. [Prior Art] In recent years, display technology, image processing, and wafer technology have continued to evolve. 'Thinness has become a trend in the development of electronic devices such as computer monitors and televisions. Taking televisions as an example, it has experienced a thin evolution from the original cathode ray tube television (CRT), rear projection television to flat panel televisions (such as plasma and LCD TV). In this evolution, the volume and installation method of the sound module including the speaker has a relatively large influence on the size of the flat-panel TV, because flat-panel TVs, especially large-sized flat-panel TVs, usually have speakers. And the display screens are assembled inside the casing, and the speakers are located on either side of the display screen or below. Since the sound emitting port of the speaker has a fixed size area, therefore, when the sound emission of the speaker is directly directed toward the front user, the sound emitting port will occupy some area on the front surface of the casing, so that the casing covering the edge of the screen is covered. The size of the part is too wide. In order to overcome the above shortcomings, a flat panel television with an improved sound module came into being. In the flat-panel video camera, the left side and the right side of the display screen disposed on the inside of the casing, the sound two = mouth direction: the money is placed, the sound reflector is a through slot structure, and the speaker is placed in the speaker Below, the reflection from the sound reflection II after the transmission (four) machine ^ emission ° sound waves through, however, in this through-the-slot structure of the sound reflector, a left-hand 6 200829054 Gu Er speaker sound waves will Interfere with each other, resulting in poor sound. • [Invention] In view of this, it is necessary to provide an electronic device with less interference. Furthermore, it is also necessary to provide a sound module applied to the above electronic device. An electronic device includes a casing and a sound module housed in the casing. The sound module includes at least two speakers and at least one sound reflector. The sound reflector includes a support portion supporting the speaker and a reflective speaker opposite to the support portion. a reflection portion of the emitted sound wave, a connection portion connecting the support portion and the reflection portion, and an interference portion between the adjacent speakers to prevent the sound waves emitted from the adjacent speakers from interfering with each other in the reflector, and the support portion is provided with The sound transmission part of the sound wave transmitted by the speaker. A sound module includes at least two speakers and a sound reflector, the sound reflector includes a support portion supporting the speaker, a reflection portion opposite to the support portion that reflects sound waves emitted from the speaker, a connection portion connecting the support portion and the reflection portion, and An interference portion between adjacent speakers that avoids sound waves emitted from adjacent speakers from interfering with each other in the reflector, and the support portion is provided with a sound-transmitting portion for transmitting sound waves emitted by the speaker. In the above electronic device and sound module, since the interference portion partitions the inside of the sound reflector to guide the sound transmission, the sound is prevented from interfering with each other inside the sound reflector, and a better sound effect can be provided for the user to enjoy. [Embodiment] The electronic device may be a computer display, a flat-panel television, or other audible device. In the following embodiments, a flat-panel television is taken as an example. • Referring to Figures 1 and 2, the flat panel television 10 includes a housing 20, a display screen 30, a sound module 40, and a bracket 50. The bottom of the casing 20 is supported by the bracket 50. The display screen 30 and the sound module 40 are received in the casing 20, and the sound module 40 is located below the display screen 30. The casing 20 has a front fascia 22 that is wrapped around the four periphery of the display screen 30, and a rear casing 24 that is fixedly fitted to the front fascia 22. The front fascia 22 is slightly smaller in size than the rear casing 24. After being assembled in the rear casing 24, a gap partially accommodating the sound module 40 is stored between the bottom edge of the front fascia 22 and the bottom edge of the rear casing 24. 3 to 5, the sound module 40 includes a pair of speakers 42 and a sound reflector 44. The speaker 42 includes a sound emitting surface 420 and a flange 422. The sound emitting surface 420 is a virtual surface on which the leading edge of the speaker 42 in the sound emission direction is located. The flange 422 extends from the portion of the speaker 42 adjacent to the sound emitting surface 420 to the periphery, and a plurality of through holes (not shown) are formed therein for fixing screws (not shown). The sound reflector 44 includes a support portion 440, a reflection portion 442 provided to face the support portion 440, a connection portion 444 connecting the support portion 440 and the reflection portion 442, and a disturbance portion 446. The support portion 440 and the reflection portion 442 are disposed at an angle α. . The support portion 440, the reflection portion 442, and the connection portion 444 are combined into a semi-closed housing structure. The support portion 440 is provided with two sound-transmitting portions 440a spaced apart from each other, a fixing seat 440b for fixing the speaker 42, a plurality of bosses 440c fixedly connected to the front fascia 22 and the rear case 24, and ribs 440d. The sound transmitting portion 440a of the present embodiment 200829054 is a grill through which sound waves emitted from the speaker 42 pass, and may be a structure in which a sound wave can pass through a diaphragm or the like. The surface of the reflecting portion 442 facing the supporting portion 440 is a sound reflecting surface 442a, and the sound reflecting surface 442a is a sloped structure with respect to the supporting portion 440, which is at an angle with the sound emitting surface 420 of the speaker 42 (such as an angle 〇〇 setting). The sound waves from the sound emitting surface 420 can be reflected. The support portion 440, the reflecting portion 442, and the portion of the connecting portion 444 located between the adjacent sound transmitting portions 440a are provided with a through slit 445 penetrating in a direction substantially perpendicular to the supporting portion 440. The rib 440d partially covers the slit 445, so that the strength of the support portion 44 can be increased to avoid deformation. The interference portion 446 connects the edges of the closed slit 445 to form a U-shaped structure, thereby supporting the support portion 440, the reflecting portion 442 and the connecting portion 444. The space between the three is divided into two chambers 447, and the end of the chamber 447 in the direction in which the sound waves reflected by the reflecting portion 442 are emitted forms a sound port 448 which restricts the sound waves emitted from the adjacent speakers 42. They are transmitted from the corresponding sound outlets 448, respectively, without mutual interference in the chamber 447. The bracket 50 has a base 52 and a post 54 extending perpendicularly from the base. 54 can be connected to the casing 20 through the slit 445. During assembly, the speaker 42 is placed on the fixing base 440b such that the sound emitting surface 420 covers the corresponding sound transmitting portion 440a and is at an angle to the reflecting portion 442. Then, the speaker 42 is fixed by screws or other means (such as snapping or bonding), then the sound reflector 44 is fixed to the bottom edge of the front fascia 22, and the bracket 50 is attached so that the struts 54 pass through the slit 445 and After the bracket (not shown) of the display screen 30 is fixedly connected, the front panel 22 and the rear panel 24 200829054 are displayed on the display screen 30, and the speaker 42 is hidden behind the front panel 22. The sound reflector 44 is just closed. When the front fascia 22 and the rear case 24 are closed, the gap between the bottom ends of the two ends is fixed, and then the support portion 440 and the rear case 24 are fixedly secured. In use, the sound waves emitted from the speaker 42 are emitted from the sound emitting surface 420. When the sound is emitted, the sound wave enters the chamber 447 through the sound-transmitting portion 440a, and after being incident on the reflecting portion 442, it is then reflected by the sound reflecting surface 442& on the reflecting portion 442, and the reflected sound wave is transmitted from the sound outlet 448 to the flat plate. TV 1Q outside. Due to the interference section 446 blocks the sound reflector 42 into two chambers 447, and directs the sound waves emitted from the adjacent speakers 42 to be respectively transmitted from the corresponding sound outlets 448 without mutual interference in the chamber 447. Therefore, the sound module 4缩小 While reducing the width of the bottom edge of the front fascia 22, it can also provide better sound effects for the user to enjoy. In other embodiments, the number of the speakers 42 is not limited to a pair, but one or more ' The number of the transmissive portions 440a may be equal to the number of the speakers (42). The sound module 4 can be disposed at the bottom of the display screen 30, or at the top of the display screen 3, or even on both sides. The slit 445 on the support portion 440 can be eliminated by merely changing the shape of the post 54 on the bracket 50, such as by partially bending the post 54 to avoid the acoustic reflector 44. The sound reflecting surface 442a is not limited to being a slope, and may be a curved surface as long as it is shaped to reflect sound waves from the speaker 42 out of the flat panel television 10.
