[0034] Currently, electronic devices with a sound box assembly have a design requirement of sound and picture integration in order to obtain a good audio-visual experience. In order to realize sound and picture integration of the electronic device and obtain a good stereo effect, the loudspeaker of the sound box assembly needs to be inclined forward and downward. In the prior art, the sound box assembly in the electronic device is rotated to realize the inclined sound emission of the loudspeaker.
[0035] The electronic device in the prior art has a problem that the sound box assembly produces resonance sound, thereby affecting the sound quality.
[0036] Please refer to Figures 1-5 The electronic device 1000 can effectively improve the above-mentioned technical problems, can alleviate the resonance sound produced by the sound box assembly 100 of the electronic device 1000, and ensure good sound quality of the electronic device 1000.
[0037] Please refer to Figure 1 The electronic device 1000 includes a sound box assembly 100 and a whole machine shell 200. The sound box assembly 100 includes a shell 110 and a loudspeaker 120. The shell 110 is arranged in the whole machine shell 200, and the loudspeaker 120 is arranged inside the shell 110. The loudspeaker 120 is arranged in a vertical direction and downwardly inclined. The whole machine shell 200 and the shell 110 define a sound emitting front cavity.
[0038] The shell 110 is provided with a gap, and the gap is in communication with the sound emitting front cavity.
[0039] In the embodiment, the electronic device 1000 with the sound box assembly 100 is a projector. In other embodiments, the electronic device 1000 with the sound box can also be a television or a radio and other electronic devices 1000 that need to emit sound. Herein, no specific limitation is made.
[0040] Further, the whole machine shell 200 is in a circular ring shape. In other embodiments, the shape of the whole machine shell 200 can be changed according to actual conditions, which can be rectangular or special-shaped. Herein, no specific limitation is made.
[0041] It can be understood that when the electronic device 1000 is a projector, the sound box assembly 100 and the projector body (not shown in the figure) are arranged in the whole machine shell 200.
[0042] More, the electronic device 1000 can be installed on the ceiling, can be placed on the desktop installation or can also be installed on the mounting rack. The electronic device 1000 in the embodiment is installed on the ceiling, and since the electronic device 1000 is installed on the ceiling, the position of the electronic device 1000 is above the person, so that in order to obtain good sound quality, the sound box assembly 100 of the electronic device 1000 needs to be inclined forward and downward.
[0043] In other embodiments, the sound emission direction of the sound box assembly 100 of the electronic device 1000 is adaptively adjusted according to the installation position of the electronic device 1000. Herein, no specific limitation is made.
[0044] Please refer to Figure 1 , specifically, in order to realize the unity of sound and picture and obtain good stereo effect, the sound box assembly 100 needs to emit sound in the direction of inclined forward and downward, but the structure stack in the whole machine shell 200 is very compact, the projector body is stacked around the sound box assembly 100, and the space inside the whole machine shell 200 is limited, so that the sound box assembly 100 cannot be rotated in the whole machine shell 200. Therefore, the loudspeaker 120 of the sound box assembly 100 is rotated, so that the loudspeaker 120 is inclined in the direction of inclined forward and downward. This way does not affect the installation of the sound box assembly 100 in the whole machine shell 200, and realizes the purpose of the sound box assembly 100 emitting sound in the direction of inclined forward and downward, so as to obtain good sound and picture experience.
[0045] When the loudspeaker 120 is inclined and arranged in the direction of inclined forward and downward, the whole machine shell 200 and the shell 110 define a sound emitting front cavity of the loudspeaker 120. In the working process of the sound box assembly 100, the resonance of the sound emitting front cavity can cause the frequency response valley of the whole machine audio to be very deep in the medium and high frequency band, and the sound listening feeling also has the resonance sound of the cavity, which seriously affects the sound quality of the whole machine. In order to solve the adverse effects of the resonance of the sound emitting front cavity on the sound effect, the present application opens a gap in the shell 110, and the gap is communicated with the sound emitting front cavity, so as to destroy the closed structure of the sound emitting front cavity. The resonance sound generated in the working process of the sound box assembly 100 is relieved, and the sound quality of the electronic device 1000 is ensured to be good.
[0046] Figures 2-4 The specific structure of the sound box assembly 100 is shown, and the structure of the sound box assembly 100 will be described in detail below.
[0047] Please refer to Figure 2 and Figure 3 , the shell 110 includes a first inclined surface 111 and a second inclined surface 112, the first inclined surface 111 is connected with the second inclined surface 112, the first inclined surface 111 has an opening 1111, and the loudspeaker 120 has a sound emitting part, which is arranged towards the opening 1111.
[0048] Specifically, in order to adapt to the shape of the sound outlet of the loudspeaker 120, the opening 1111 is circular. In other embodiments, the shape of the opening 1111 can be arc-shaped or rectangular, which is not specifically limited here.
[0049] Please refer to Figure 3 Since the loudspeaker 120 needs to be tilted towards the obliquely downward direction in order to achieve sound-picture integration and obtain good stereo effect, the loudspeaker 120 needs to be tilted towards the obliquely downward direction, the first inclined surface 111 and the second inclined surface 112 are V-shaped, and the inclination angle of the first inclined surface 111 is the same as the inclination angle of the loudspeaker 120.
[0050] Please refer to Figure 3 Specifically, in the present embodiment, the included angle between the first inclined surface 111 and the second inclined surface 112 is obtuse, and the range is between 90 degrees and 130 degrees.
[0051] Further, in order to ensure good sound quality of the loudspeaker 120, the inclination angle of the loudspeaker 120 ranges from 10 degrees to 30 degrees. In the present embodiment, the inclination angle of the loudspeaker 120 refers to the included angle between the loudspeaker 120 and the vertical direction.
[0052] The included angle between the first inclined surface 111 and the second inclined surface 112 and the inclination angle of the loudspeaker 120 are both pre-set through experimental data, which can be adjusted according to actual needs later.
[0053] Please refer to Figure 4 Further, the shell 110 includes a first side wall 113 and a second side wall 114, the first side wall 113, the first inclined surface 111, the second inclined surface 112, the second side wall 114, and the whole machine shell 200 define a sound emitting front cavity.
[0054] In the present embodiment, the thickness of the first side wall 113 is less than the thickness of the second side wall 114. In other embodiments, the thickness of the first side wall 113 can be equal to or greater than the thickness of the second side wall 114. This is not specifically limited here.
[0055] In the relative position of Figure 4 , the first side wall 113 is located on the left side of the first inclined surface 111, and the second side wall 114 is located on the right side of the first inclined surface 111.
[0056] In the relative position of Figure 4 , the left-right direction shown in Figure 4 can be understood as the relative position of the sound box assembly 100 in Figure 4 , or the relative positional relationship when the product is placed conventionally.
[0057] The gap includes a first gap 1131 and a second gap 1141. The first gap 1131 is opened to the edge of the first sidewall 113, and the second gap 1141 is opened to the second sidewall 114. Both the first gap 1131 and the second gap 1141 are connected to the pre-vocal cavity.
[0058] The second sidewall 114 is also provided with a sound-venting groove 115, which extends through the bottom and top of the second sidewall 114 and communicates with the second notch 1141. Specifically, the sound-venting groove 115 is elongated. In other embodiments, the shape of the sound-venting groove 115 can be changed according to the actual situation, and is not specifically limited here.
[0059] Figure 5 The specific structure of the casing 200 is shown. The structure of the casing 200 will be described in detail below.
[0060] Please refer to Figure 5 In order to achieve audio-visual integration and obtain a good stereo effect without damaging the structural strength of the casing 200, the casing 200 is provided with a first through hole 220. The position of the first through hole 220 is adapted to the setting position of the speaker 120, and the first through hole 220 is connected to the sound front cavity.
[0061] In this embodiment, the first through hole 220 is circular. In other embodiments, the shape of the first through hole 220 can be rectangular or triangular. No specific limitation is made here.
[0062] When the electronic device 1000 is a projector, for the speaker 120 to produce sound, an opening must be made in the casing 200. The thickness of the projector casing 200 is generally 2.5mm-3mm. If a hole perpendicular to the casing 200 is made, due to the considerable thickness of the casing 200, the thick vertical sound outlet 211 will guide the sound forward, thus failing to achieve oblique downward sound output. Therefore, to achieve the purpose of the speaker 120 outputting sound obliquely downward, an oblique downward through-hole needs to be made in the casing 200. However, since it is difficult to directly make an oblique downward through-hole in the casing 200 using molds in actual manufacturing processes, in this embodiment, the first through-hole 220 is covered by a mesh cover 210, the thickness of which is less than 1mm. Specifically, the mesh cover 210 has multiple sound outlet holes 211, and these multiple sound outlet holes 211 are arranged obliquely downward to achieve the purpose of the speaker 120 outputting sound obliquely downward.
[0063] More preferably, the thickness of the mesh cover 210 is less than 0.6 mm.
[0064] The outer casing 200 also has a second through hole 230, which is connected to the sound front cavity.
[0065] Specifically, the number of the second through holes 230 is multiple, and the multiple second through holes 230 are distributed above and below the first through hole 220.
[0066] In the embodiment, two rows of second through holes 230 are arranged above the first through hole 220, and one row of second through holes 230 is arranged below the first through hole 220. In other embodiments, the distribution position of the second through holes 230 can be changed according to actual conditions, which is not specifically limited here.
[0067] Further, the diameter of the second through hole 230 is smaller than the diameter of the first through hole 220.
[0068] The mesh cover 210 covers the first through hole 220 and the second through hole 230.
[0069] In the embodiment, the mesh cover 210 is square. In other embodiments, the mesh cover 210 can also be circular, which is not specifically limited here.
[0070] The electronic device 1000 provided in the embodiment has at least the following advantages:
[0071] When the loudspeaker 120 is obliquely and downwardly arranged, the whole machine shell 200 and the shell 110 define a sound emitting front cavity of the loudspeaker 120. During the working process of the sound box assembly 100, the resonance of the sound emitting front cavity can cause a very deep frequency response valley in the medium and high frequency band of the whole machine audio frequency response, and the sound listening feeling also has a cavity resonance sound, which seriously affects the sound quality of the whole machine. In order to solve the adverse effects of the sound emitting front cavity resonance on the sound effect, the present application opens a gap in the shell 110, and the gap is in communication with the sound emitting front cavity, thereby destroying the closed structure of the sound emitting front cavity. The resonance sound generated in the working process of the sound box assembly 100 is relieved, and the sound quality of the electronic device 1000 is ensured to be good.
[0072] In summary, the electronic device 1000 provided in the embodiment includes a whole machine shell 200 and a sound box assembly 100. The sound box assembly 100 includes a shell 110 and a loudspeaker 120. The shell 110 is arranged in the whole machine shell 200, and the loudspeaker 120 is arranged inside the shell 110. The loudspeaker 120 is arranged obliquely and downwardly along the vertical direction. The whole machine shell 200 and the shell 110 define a sound emitting front cavity. The shell 110 is provided with a gap, and the gap is in communication with the sound emitting front cavity. Since the sound emitting front cavity defined by the whole machine shell 200 and the shell 110 can resonate to cause a resonance sound during the working process of the sound box assembly 100, the electronic device 1000 opens a gap in the shell 110, and the gap is in communication with the sound emitting front cavity. The gap destroys the closed structure of the sound emitting front cavity, relieves the resonance sound generated in the working process of the sound box assembly 100, and ensures the sound quality of the electronic device 1000 to be good.
[0073] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
