[0018] Embodiments of the present application

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Fig. 1 and Fig. 2, Fig. 1 is a first structure schematic diagram of the existing electronic device, and Fig. 2 is a second structure schematic diagram of the existing electronic device.

[0021] At present, the fixed mode of some electronic devices 1 such as television is often fixed on the wall 200, and the distance between the back shell 2 and the wall 200 is basically 8 to 35 mm. The distance can support the back shell 2 of the electronic device 1 to adopt a hollow structure (heat dissipation hole 3) to realize large-area heat dissipation of the heating device 4 in the electronic device 1.

[0022] In order to further reduce the space occupied by the electronic device 1, the distance between the electronic device 1 and the wall 200 is closer and closer until the distance between the rear shell 2 of the electronic device 1 and the wall 200 is 0-5 mm. Obviously, the distance cannot support the rear shell 2 of the electronic device 1 to be hollowed out for heat dissipation, and can only support the natural convection heat dissipation of the heat dissipation hole 3 in the vertical direction, so that the heat dissipation is more difficult. However, the heat dissipation hole 3 at the bottom of the electronic device 1 is often blocked by the sound 5, which blocks the airflow to take away heat.

[0023] If a fan is directly arranged corresponding to the heat generating device 4, the thickness of the electronic device 1 will be increased, which is not conducive to the pursuit of thinness of the electronic device 1.

[0024] In order to solve the above problems, the electronic device and the television provided in the embodiments of the present application can enhance the heat dissipation capacity of the electronic device. The following will be specifically described with reference to the accompanying drawings.

[0025] Please refer to FIG. 3, which is a first schematic diagram of the electronic device provided in the embodiments of the present application.

[0026] The electronic device 100 provided in the embodiments of the present application can be a smart watch, a smart phone, a television, a computer, a display screen or the like. In the embodiments of the present application, the electronic device 100 is mainly taken as a television for example.

[0027] The electronic device 100 comprises a first shell 10, a heat generating device 20 and a sound 30.

[0028] The first shell 10 is the main shell of the electronic device 100, which is used to protect the internal structure of the electronic device 100 and play the role of appearance modification. The first shell 10 has a first accommodating cavity 11 and a heat dissipation hole 12, and the first accommodating cavity 11 is in communication with the heat dissipation hole 12. The first accommodating cavity 11 is used to accommodate the main structure of the electronic device 100, and comprises the heat generating device 20 and the sound 30. It can be understood that the heat generated by the heat generating device 20 can escape to the outside of the first shell 10 through the heat dissipation hole 12, so as to avoid heat accumulation.

[0029] The heat generating device 20 can be a circuit board or an electronic element on the circuit board, for example, the electronic element is a movement, a power supply or the like. The heat generating device 20 will generate heat when working.

[0030] The sound 30 can include but is not limited to ordinary sound, bass sound, sky sound, surround sound and the like. Please refer to FIG. 4, which is a first structure schematic diagram of the sound provided in the embodiments of the present application: FIG. 4(1) is a structure schematic diagram of the loudspeaker of the sound in a first state; and FIG. 4(2) is a structure schematic diagram of the loudspeaker of the sound in a second state.

[0031] The sound box 30 has a first inverting tube 31 which is in communication with the first accommodating cavity 11. It can be understood that the sound box 30 can also be an inverting sound box 30. When the inverting sound box 30 works, the diaphragm of the loudspeaker 33 in the sound box 30 generates sound by vibration to transmit the sound to the outside. The loudspeaker 33 and the air inside the first accommodating cavity 11 generate resonance, and the sound wave generated by vibration will be output to the outside of the sound box 30 through the first inverting tube 31, thereby strengthening the sound wave transmission and making the bass effect better.

[0032] According to the above, the loudspeaker 33 generates sound to drive the air inside the sound box 30 to flow from the first inverting tube 31 into the first accommodating cavity 11, and then drive the heat generated by the heat generating device 20 from the heat dissipation hole 12 to the outside of the first shell 10 to actively dissipate heat for the heat generating device 20.

[0033] When the electronic device 100 is a television, the television can ensure that the temperature rise of the heat generating device 20 in the electronic device 100 is reduced without affecting the performance and cost, and the reliability of the electronic device 100 hung on or against the wall is improved.

[0034] Please continue to refer to FIG. 3, in order to further improve the heat dissipation capacity of the electronic device 100, in a feasible case, the first inverting tube 31 is directed towards the heat generating device 20, so that the loudspeaker 33 generates sound to drive the air inside the sound box 30 to flow against the heat generating device 20, thereby enhancing the heat dissipation capacity of the electronic device 100.

[0035] The number of heat dissipation holes 12 is multiple, and the multiple heat dissipation holes 12 include a first heat dissipation hole 121 and a second heat dissipation hole 122, and the first heat dissipation hole 121 is arranged opposite to the second heat dissipation hole 122. It can be understood that the first shell 10 of the electronic device 100 has a main body part and multiple side parts, the main body part is arranged corresponding to the back plate of the electronic device 100, and the side parts are arranged around the main body part. In contrast, when the electronic device 100 is in use, the multiple side parts can be divided into top side parts, bottom side parts, left side parts and right side parts according to different positions. For example, in some cases, the first heat dissipation hole 121 is in the top side part, and the second heat dissipation hole 122 is in the bottom side part; in other cases, the first heat dissipation hole 121 is in the right side part, and the second heat dissipation hole 122 is in the left side part; or each side part is provided with a heat dissipation hole 12.

[0036] Please continue to refer to FIG. 3, taking the first heat dissipation hole 121 at the top side and the second heat dissipation hole 122 at the bottom side as examples, external air can pass through the openings of the first heat dissipation hole 121 and the second heat dissipation hole 122 to achieve air convection, thereby achieving air circulation heat dissipation of the electronic device 100. The heat generating device 20 is arranged inside the shell, the first inverting tube 31 of the acoustic device 30 is arranged opposite to the heat generating device 20, and the diaphragm of the acoustic device 30 is arranged on the side opposite to the first inverting tube 31, so that the first heat dissipation hole 121, the heat generating device 20, the first inverting tube 31 of the acoustic device 30, the diaphragm of the acoustic device 30, and the second heat dissipation hole 122 are approximately arranged on the same straight line, the air circulation is smoother, and the heat dissipation effect is better.

[0037] In order to prevent air flow from generating noise, the wall of the first inverting tube 31 is curved, which is beneficial to air flow buffering and avoids air impacting the wall of the first inverting tube 31 to form noise.

[0038] In some embodiments, please continue to refer to FIG. 4 and FIG. 5, FIG. 5 is a second structure schematic diagram of an acoustic device provided by an embodiment of the present application: FIG. 5(1) is a structure schematic diagram of a loudspeaker of the acoustic device in a first state; and FIG. 5(2) is a structure schematic diagram of the loudspeaker of the acoustic device in a second state. The acoustic device 30 includes a second shell 32 and a loudspeaker 33, the second shell 32 is provided with a second accommodating cavity 321 and a first inverting tube 31, the second accommodating cavity 321 is in communication with the first inverting tube 31, and the loudspeaker 33 is at least partially arranged in the second accommodating cavity 321, and the first inverting tube 31 is in communication with the first accommodating cavity 11 and the second accommodating cavity 321. The loudspeaker 33 can be fixed on the second shell 32, one side of the loudspeaker 33 with a diaphragm is exposed outside the second shell 32, and the side of the loudspeaker 33 away from the diaphragm faces into the second accommodating cavity 321. When the acoustic device 30 works, the diaphragm of the loudspeaker 33 generates sound through vibration to transmit the sound to the outside. At the same time, the side of the loudspeaker 33 away from the diaphragm also generates vibration to cause the air inside the loudspeaker 33, the second accommodating cavity 321, and the first inverting tube 31 to resonate, and the sound waves generated by vibration are output to the outside of the second shell 32 through the first inverting tube 31, thereby strengthening the transmission of sound waves; the diaphragm generates up-down displacement when vibrating, which also drives the air inside the acoustic device 30 to pass through the first inverting tube 31 to enter and exit, thereby generating air flow to dissipate heat of the heat generating device 20.

[0039] In some cases, please refer to Fig. 4, the sound box 30 further comprises a baffle 34, the baffle 34 is arranged in the second accommodating cavity 321, the baffle 34 is connected with the second shell 32, and the baffle 34 and the second shell 32 jointly form the first inverse pipe 31. That is, the baffle 34 and the second shell 32 jointly form the first inverse pipe 31. Further, by setting the position and length of the baffle 34, the position and length of the first inverse pipe 31 can be further determined, thereby facilitating the resonance of the air in the loudspeaker 33, the second accommodating cavity 321 and the first inverse pipe 31, and the bass effect is better.

[0040] Wherein, the loudspeaker 33 can be arranged on one side of the second shell 32, and the number of loudspeakers 33 can be one or two according to the size of the accommodating cavity surrounded by the second shell 32. When the number of loudspeakers 33 is more than one, the loudspeakers 33 can be arranged on the same side or opposite sides of the second shell 32. Of course, please continue to refer to Fig. 5, the loudspeaker 33 can be arranged opposite to the first inverse pipe 31, for example, the loudspeaker 33 is arranged on the upper side of the second shell 32, and the first inverse pipe 31 is arranged on the lower side of the second shell 32, and the first inverse pipe 31 is opposite to the back of the loudspeaker 33, that is, the loudspeaker 33 is arranged opposite to the side away from the diaphragm of the first inverse pipe 31, so that the air excited by the vibration of the back of the loudspeaker 33 can better leak out of the first inverse pipe 31, thereby improving the heat dissipation capacity of the sound box 30 for the heat generating device 20.

[0041] The second shell 32 has an opening (second opening 323) communicating with the second accommodating cavity 321, and the loudspeaker 33 has a diaphragm exposed to the second opening 323. When the loudspeaker 33 and the first inverse pipe 31 are arranged on opposite sides of the second shell 32, for example, on the upper and lower sides, the back of the loudspeaker 33 can be kept opposite to the first inverse pipe 31, thereby improving the efficiency and quality of sound wave transmission and the heat dissipation capacity of the sound box 30 for the heat generating device 20.

[0042] Wherein, the second shell 32 is sealingly connected with the loudspeaker 33, which can improve the efficiency and quality of sound wave transmission, prevent sound leakage, and improve the excitation strength of the loudspeaker 33 on the air in the second accommodating cavity 321 of the second shell 32.

[0043] The sealing connection between the second shell 32 and the loudspeaker 33 can be achieved in various ways, such as by using adhesive, adding a sealing ring, and welding.

[0044] In other cases, please refer to Fig. 6, which is a second schematic diagram of an electronic device provided by the present application. The sound box 30 further comprises a second inverse pipe 35, one end of the second inverse pipe 35 communicates with the first accommodating cavity 11, and the other end communicates with the second accommodating cavity 321.

[0045] In order to realize the conduction between the second inverter tube 35 and the second accommodating cavity 321, an opening (marked as a first opening 322) can be arranged on the second shell 32, and the first opening 322 is in communication with the second accommodating cavity 321. The second inverter tube 35 is inserted into the first opening 322, and the second inverter tube 35 is in communication with the second accommodating cavity 321 through the first opening 322, and the side wall of the first opening 322 is sealingly connected with the second inverter tube 35. The advantage of this arrangement is that it can prevent air leakage between the second inverter tube 35 and the second shell 32, thereby enhancing the sound transmission effect of the second inverter tube 35.

[0046] In the above case, the side wall of the first opening 322 is sealingly connected with the second inverter tube 35, which can be achieved by using glue, adding a sealing ring, and welding, etc. However, since the second shell 32 is generally made of plastic material, it is preferred to use glue to achieve sealing, which only needs to fill glue at the intersection of the first opening 322 and the second inverter tube 35, without any structural modification, and will not damage the second shell 32 and the second inverter tube 35.

[0047] It should be pointed out that one end of the second inverter tube 35 penetrates through the first opening 322, so that one end of the second inverter tube 35 is arranged inside the accommodating cavity, and the first opening 322 is sealingly connected with the outer wall of the second inverter tube 35, for example, by filling glue between the pipe wall of the first opening 322 and the outer pipe wall of the second inverter tube 35. As shown in the figure, at this time, only the upper end of the second inverter tube 35 is arranged in the accommodating cavity, so that this installation method not only only occupies a small part of the space of the accommodating cavity, but also can enhance the installation stability of the second inverter tube 35, and avoid the phenomenon of falling off of the second inverter tube 35.

[0048] It should be pointed out that after arranging one end of the second inverter tube 35 in the accommodating cavity, the distance between the port of the second inverter tube 35 and the loudspeaker 33 is shortened, that is, the sound wave transmission distance between the loudspeaker 33 and the second inverter tube 35 is reduced, thereby improving the sound wave transmission efficiency; at this time, in order to further improve the sound wave transmission efficiency, as shown in the figure, one end of the second inverter tube 35 arranged in the second accommodating cavity 321 can be extended towards the loudspeaker 33, that is, the upper end is arranged as close to the loudspeaker 33 as possible, so as to further reduce the distance between the port of the second inverter tube 35 and the loudspeaker 33, thereby providing an important guarantee for improving the sound wave transmission efficiency of the second inverter tube 35.
