Description

Technical Field

[0001] The embodiments of the present application relate to the field of projection display technology, and more particularly to a projection device. Background Art

[0002] With the continuous development of science and technology, projection equipment is increasingly used in people's work and life. Projection equipment has the advantages of small size, portability, and adjustable display screen. The projection equipment includes a projection module and a speaker. The projection module can be configured to project a screen. The speaker can be configured to emit corresponding sounds, so that the projection equipment can play sounds while displaying the screen.

[0003] In the related art, the speaker and the projection module are connected through a wireless Bluetooth module. However, the wireless connection method is prone to delays and asynchronism between the speaker and the projection module. In other words, the sound emitted by the speaker is not synchronized with the picture projected by the projection module. If the speaker and the projection module are connected by wire, when the angle of the projection device is adjusted (for example, when the projection module is rotated 360°), it is easy to cause the connection line between the speaker and the projection module to be pulled and twisted, which can easily lead to poor connection between the speaker and the projection module, affecting the user experience. Utility Model Content

[0004] The embodiment of the present application provides a projection device, which can solve the problem of poor connection between the speaker and the projection module caused by pulling or twisting of the connecting line between the speaker and the projection module during the angle adjustment of the projection device while achieving synchronization between the projected image and the played sound.

[0005] In a first aspect, an embodiment of the present application provides a projection device, comprising:

[0006] a projection subject configured to project an image;

[0007] A speaker, configured to play sound, the speaker being electrically connected to the projection body via a connecting line;

[0008] A first adjustment seat, the projection body and the connecting line are arranged on the first adjustment seat, and the first adjustment seat is provided with a receiving space for accommodating the speaker and the connecting line;

[0009] The first adjustment seat is rotatably connected to the second adjustment seat, so that the projection body, the speaker, the connecting line and the first adjustment seat move synchronously.

[0010] In the embodiment of the present application, the projection body and the speaker can be connected by a connecting line so that the projection body and the speaker can operate synchronously, and the image projected by the projection body can correspond to the sound played by the speaker. In addition, since the projection body and the speaker are both arranged on the first adjustment seat, the first adjustment seat can be rotatably connected to the second adjustment seat by setting the first adjustment seat to be rotatable, so that the first adjustment seat can be rotated 360° relative to the second adjustment seat to adjust the position of the projection body. During the rotation of the first adjustment seat, the projection body, the speaker, and the connecting line used to connect the two can all move synchronously with the first adjustment seat. In other words, the connecting line and the projection body and the speaker can be relatively still, thereby reducing the possibility that the connecting line is pulled or twisted, thereby affecting the connection reliability between the projection body and the speaker.

[0011] In some embodiments of the present application, the first adjustment seat has a avoidance hole along the first direction, the avoidance hole corresponds to the sound outlet of the speaker, and the avoidance hole faces the projection body;

[0012] A fixing bracket for fixing the speaker is disposed in the first adjustment seat, the fixing bracket is located in the accommodating space, and the fixing bracket is configured to support the projection body so that the projection body and the speaker are spaced apart.

[0013] In the embodiment of the present application, the sound outlet of the speaker can correspond to the avoidance hole of the first adjustment seat, so that the sound played by the speaker outlet can be released through the avoidance hole. By setting a fixed bracket, the projection body and the speaker can be spaced apart, thereby preventing the projection body from blocking the sound outlet of the speaker.

[0014] In some embodiments of the present application, along the first direction, the speaker is located on a side of the fixed bracket facing the projection body, the fixed bracket is provided with a wiring groove extending in the direction of the projection body, one end of the connecting wire is connected to the speaker, and the other end is connected to the projection body, and at least part of the connecting wire is located in the wiring groove.

[0015] In the embodiment of the present application, by providing a wiring groove on the fixed bracket, a wiring space can be provided for the connecting wires, and the side wall of the wiring groove can also be used to provide a wiring path for the connecting wires, so that the connecting wires can be wired along the wiring path provided by the wiring groove to connect to the projection body. The wiring groove can make the connecting wires neatly arranged on the fixed bracket, reducing the possibility that the connecting wires are entangled with the fixed bracket or other structures in the first connection seat, causing the connecting wires to be pulled and affecting the reliability of the connection between the projection body and the speaker.

[0016] In some embodiments of the present application, the first adjustment seat is rotatably connected to the projection body via a first rotating shaft, and the first rotating shaft is provided with a threading hole so that the connecting wire can be passed through the threading hole to be connected to the projection body.

[0017] In the embodiment of the present application, when the projection device is placed on a lower horizontal plane, the projection body is arranged above the second adjustment seat through the first adjustment seat. The first adjustment seat can be configured to adjust the pitch angle of the projection body by rotating the first rotation axis. Therefore, when the projection device is placed horizontally, the user can adjust the position of the projection body in the horizontal direction by adjusting the first adjustment seat to rotate relative to the second adjustment seat; by operating the projection body to rotate relative to the first adjustment seat around the first rotation axis, the pitch angle of the projection body can be adjusted to meet the visual requirements of the projection device projecting the image.

[0018] The connection line between the speaker and the projection body can be passed along the wiring groove of the fixing bracket and through the threading hole on the first rotating shaft to enter the housing of the projection body, thereby being electrically connected to the projection module located in the housing. Since the pitch angle is less than 360°, the projection body is adjusted within a certain range. Therefore, during the process of adjusting the pitch of the projection body, the twisting angle of the connection line is small, which is conducive to reducing the possibility of poor connection between the connection line and the projection body and the speaker during the process of adjusting the pitch angle of the projection body.

[0019] In some embodiments of the present application, the first adjustment seat is rotatably connected to the second adjustment seat via the second rotating shaft, and along the first direction, the first adjustment seat and the projection body are located on the same side of the second adjustment seat.

[0020] In an embodiment of the present application, when adjusting the rotation angle of the first adjustment seat relative to the second adjustment seat, the first adjustment seat and the projection body located on the same side of the second adjustment seat can move synchronously. At this time, the connecting line can also move synchronously with the first adjustment seat and the projection body, thereby reducing the possibility of the connecting line being subjected to torsion, pulling and other forces, thereby affecting the connection stability between the projection body and the speaker.

[0021] In some embodiments of the present application, the projection device includes a fixing column and a connecting piece, the fixing column is arranged on the fixing bracket, and the connecting piece fixes the speaker to the fixing column;

[0022] The projection device further comprises a shock absorbing member, part of which is located between the speaker and the fixing column, and part of which is located between the speaker and the connecting member.

[0023] The shock absorber of the embodiment of the present application can be configured to absorb at least part of the vibration generated by the speaker. Specifically, during the vibration of the speaker, the shock absorber can absorb part of the vibration generated by the speaker to avoid a rigid connection between the speaker and the connecting member or the fixed column, and reduce the possibility of a rigid collision between the fixed bracket and the speaker to produce an abnormal sound, thereby affecting the possibility of the broadcasting effect. In addition, the shock absorber absorbs part of the vibration generated by the speaker, which can reduce the vibration generated by the speaker that is transmitted to the fixed bracket through the fixed column, and then transmitted to the projection body by the fixed bracket, thereby reducing the impact of the vibration of the speaker causing the projection body to shake, and the image projected by the projection body to shake.

[0024] In some embodiments of the present application, along the first direction, a first shock-absorbing protrusion is protruding from the surface where the shock-absorbing member is connected to the connecting member, and a second shock-absorbing protrusion is protruding from the surface where the shock-absorbing member is connected to the fixing column.

[0025] In the embodiment of the present application, the first shock-absorbing protrusion can provide a buffer gap for the vibration of the speaker along the first direction toward the projection body, and the second shock-absorbing protrusion can provide a buffer gap for the vibration of the speaker along the first direction toward the fixed column. Therefore, during the vibration of the speaker, the first shock-absorbing protrusion and the second shock-absorbing protrusion can produce compression deformation, so that the vibration of the speaker is not easily transmitted to the fixed bracket, thereby reducing the phenomenon of the jitter of the projected image of the projection body. In addition, it is easy to understand that the compression of the first shock-absorbing protrusion and the second shock-absorbing protrusion is not easy to hinder the vibration generated during the operation of the speaker, so as to ensure the playback effect of the speaker.

[0026] In some embodiments of the present application, the speaker has a first mounting surface and a second mounting surface opposite to each other along a first direction, the first mounting surface is configured to be connected to the connecting member, and the second mounting surface is configured to be connected to the fixing column;

[0027] The shock absorbing member comprises a first shock absorbing portion and a second shock absorbing portion, the first shock absorbing protrusion is arranged on the first shock absorbing portion, and the second shock absorbing protrusion is arranged on the second shock absorbing portion;

[0028] The first shock absorbing part is arranged on the first mounting surface so that the connecting member is indirectly connected to the first mounting surface, and the second shock absorbing part is arranged on the second mounting surface so that the second mounting surface is indirectly connected to the connecting member.

[0029] In the embodiment of the present application, the connecting member and the first mounting surface can be flexibly connected through the first shock absorbing part. The connecting member and the second mounting surface can be flexibly connected through the second shock absorbing part. Therefore, the first shock absorbing part and the second shock absorbing part can absorb part of the vibration generated during the operation of the speaker, reduce the possibility that the vibration of the speaker is transmitted to the projection body through the fixed column and the fixed bracket, causing the image projected by the projection body to shake, thereby affecting the user experience.

[0030] In some embodiments of the present application, the first adjustment seat includes a first shell and a second shell, and the first shell and the second shell are arranged to form the accommodation space.

[0031] The projection device further includes a support column, which is disposed on the fixing bracket and passes through the speaker to be connected to the first shell.

[0032] In the embodiment of the present application, a support column can be provided to support the area of ​​the first shell near the sound outlet, thereby reducing the possibility of collapse or deformation of the area of ​​the first shell near the sound outlet due to slight external force.

[0033] In a second aspect, an embodiment of the present application provides a projection device, comprising a projection body, a speaker, a first adjustment seat and a second adjustment seat, the projection body being configured to project an image, the speaker being configured to play a sound, the speaker being electrically connected to the projection body via a connecting line, the projection body and the speaker being both disposed on the first adjustment seat, the second adjustment seat being configured to support the first adjustment seat, the first adjustment seat being rotatably connected to the second adjustment seat so that the projection body, the speaker, the connecting line and the first adjustment seat move synchronously.

[0063] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] A projection device is a device that can project images or videos onto a wall or screen. With the continuous development of technology, projection devices are developing in the direction of small size, easy to carry, and adjustable display screen. Therefore, they are widely used in various application environments such as homes, offices, schools, and entertainment venues.

[0066] The projection device can integrate a projection module and a speaker to project images or videos onto a receiving medium such as a wall or a screen through the projection module, and play the corresponding sound of the video screen through the speaker, so that the projection device can play sound while displaying the screen.

[0067] In the related art, the speaker and the projection module are connected via a wireless Bluetooth module. However, the wireless connection method is prone to delay and asynchronism between the speaker and the projection module. In other words, the sound emitted by the speaker is not synchronized with the image projected by the projection module.

[0068] If the speaker and the projection module are connected by wire, when the angle of the projection device is adjusted (for example, when the projection module is rotated 360°), the connection wire between the speaker and the projection module is easily pulled or twisted. When the connection wire is repeatedly pulled or twisted, it is easy to cause a poor connection between the speaker and the projection module, affecting the user experience.

[0069] Based on the above technical problems, the applicant has improved the structure of the existing projection equipment. In the embodiment of the present application, the projection body and the speaker can be connected by a connecting line so that the projection body and the speaker can operate synchronously, and the image projected by the projection body and the sound played by the speaker can correspond. In addition, since the projection body and the speaker are both arranged on the first adjustment seat, by setting the first adjustment seat to be rotatably connected to the second adjustment seat, the rotation angle of the first adjustment seat relative to the second adjustment seat can be greater than 360°, so as to adjust the position of the projection body. During the rotation of the first adjustment seat, the projection body, the speaker and the connecting line used to connect the two can all move synchronously with the first adjustment seat. In other words, the connecting line and the projection body and the speaker can be relatively still, thereby reducing the possibility that the connecting line is pulled or twisted, thereby affecting the connection reliability between the projection body and the speaker.

[0070] The projection device 100 provided in the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

Figure 4 A schematic diagram of a three-dimensional structure of a projection device 100 provided in an embodiment of the present application after the second shell 142 is hidden. Figure 5 This is a schematic diagram of a three-dimensional structure in which the speaker 120 provided in an embodiment of the present application is fixed between a fixing bracket 160 and a first shell 141 . Figure 6 A schematic diagram of a partial exploded structure of a projection device 100 provided in an embodiment of the present application.

[0072] See also Figures 1 to 6 As shown, the projection device 100 of the embodiment of the present application may include a projection body 110. The projection body 110 may be used to emit a light beam to a curtain or a wall to display a picture through the curtain or the wall.

[0073] In some examples, the projection body 110 may include a housing 111 and a projection module. The projection module may be located in the housing 111 to protect the projection module.

[0074] In some embodiments, the projection device 100 may include a speaker 120. The speaker 120 may be configured to play sound. The speaker 120 of the embodiment of the present application may be electrically connected to the projection body 110 via a connecting line 130 so that the projection body 110 and the speaker 120 may operate synchronously, thereby reducing the possibility of the effect projected by the projection body 110 and the sound played by the speaker 120 being out of sync.

[0075] In some examples, the speaker 120 may be a bass speaker (commonly known as a subwoofer). The bass speaker may enhance the bass area to make the sound fuller, thereby improving the user experience.

[0076] In some embodiments, the projection device 100 may include a first adjustment seat 140 . The projection body 110 and the connection line 130 may be disposed on the first adjustment seat 140 , and the first adjustment seat 140 may be provided with an accommodation space 140 a for accommodating the speaker 120 and the connection line 130 .

[0077] In the embodiment of the present application, the accommodation space 140a may be a relatively closed space, or the accommodation space 140a may have an opening, or the accommodation space 140a may be formed by a groove structure, which is not limited in the present embodiment. The speaker 120 may be fixed in the accommodation space 140a.

[0078] In some examples, the projection body 110 may be connected to the first adjustment base 140 via the housing 111 .

[0079] In some embodiments, the projection device 100 may include a second adjustment base 150. The first adjustment base 140 may be rotatably connected to the second adjustment base 150, so that the projection body 110, the speaker 120, the connection line 130 and the first adjustment base 140 move synchronously.

[0080] In the embodiment of the present application, since the projection body 110, the connecting wire 130 and the speaker 120 can all be arranged on the first adjustment seat 140, the projection body 110, the connecting wire 130 and the speaker 120 can form a whole with the first adjustment seat 140 and move synchronously. The position of the projection body 110 can be adjusted by adjusting the position of the first adjustment seat 140 relative to the second adjustment seat 150. In the process of adjusting the first adjustment seat 140, the connecting wire 130 and the projection body 110 and the speaker 120 can be relatively still, thereby reducing the possibility that the connecting wire 130 is pulled or twisted to affect the connection reliability of the projection body 110 and the speaker 120.

[0081] In some examples, the range of rotation of the first adjustment seat 140 relative to the second adjustment seat 150 in the embodiment of the present application can be n*360° (n is a natural number). Therefore, after the user uses the projection device 100 to play, it is not necessary to reset the position of the first adjustment seat 140. When the projection device 100 is used again, the first adjustment seat 140 can be adjusted to adjust the position of the projection body 110. In the process of adjusting the position of the first adjustment seat 140, even if the first adjustment seat 140 rotates multiple 360° relative to the second adjustment seat 150, the connection stability of the connecting line 130 should not be affected.

[0082] In some embodiments, the projection device 100 of the embodiment of the present application can be placed at a lower position such as a coffee table or a desktop, or can be hoisted or hung on a ceiling or a wall. The projection device 100 can be placed horizontally, tilted, or upside down, which is not limited in this embodiment. The position of the projection device 100 can be fixed according to the specific application environment.

[0083] For example, when the projection device 100 is placed horizontally on a lower horizontal plane, the first adjustment seat 140 rotates relative to the second adjustment seat 150 to adjust the horizontal position of the projection body 110. Since the connecting wire 130 is not arranged between the first adjustment seat 140 and the second adjustment seat 150, the connecting wire 130 is not easily pulled or twisted during the rotation of the first adjustment seat 140 relative to the second adjustment seat 150, which can effectively reduce the unstable connection between the projection body 110 and the speaker 120.

[0084] In some possible implementations, see Figure 3 As shown, the first adjustment seat 140 may have an avoidance hole 140b along the first direction X. The avoidance hole 140b may face the projection body 110. The sound outlet 120a of the speaker 120 may correspond to the avoidance hole 140b of the first adjustment seat 140, so that the sound played by the sound outlet 120a of the speaker 120 can be released through the avoidance hole 140b.

[0085] In some examples, when the projection device 100 is placed at a lower position such as a coffee table, it can be fixed to the coffee table through the second adjustment seat 150. The projection body 110 can be arranged above the second adjustment seat 150 through the first adjustment seat 140. The sound outlet 120a of the first adjustment seat 140 can face upward so that the sound played by the speaker 120 can diffuse upward. Similarly, when the projection device 100 is suspended in a higher position such as a ceiling, the projection device 100 can be fixed to the ceiling through the second adjustment seat 150. The sound outlet 120a of the first adjustment seat 140 can face downward so that the sound played by the speaker 120 can diffuse downward.

[0086] In some examples, along the first direction X and pointing toward the projection body 110 , at least 12 mm of unobstructed space may be reserved at the sound outlet 120 a of the speaker 120 , so that the sound outlet 120 a is not easily obstructed.

[0087] In some embodiments, see Figures 3 to 5 As shown, a fixing bracket 160 for fixing the speaker 120 may be provided in the first adjustment seat 140. The fixing bracket 160 may be located in the accommodation space 140a. The fixing bracket 160 may be configured to support the projection body 110 so that the projection body 110 and the speaker 120 are spaced apart, thereby preventing the projection body 110 from blocking the sound outlet 120a of the speaker 120.

[0088] In some examples, the projection body 110 has a certain weight, and there is a gap between the projection body 110 and the speaker 120. Therefore, the fixed bracket 160 of the embodiment of the present application can be a die-casting or cast iron part, which is used to increase the counterweight of the projection device 100 and reduce the possibility that the projection device 100 will flip over due to the weight of the projection body 110, thereby affecting the normal use of the projection device 100.

[0089] In addition, the fixing bracket 160 is a die-casting or cast iron part, which can have a higher processing accuracy, so as to be configured to improve the assembly accuracy and assembly efficiency of the speaker 120 and the fixing bracket 160 .

[0090] In some possible implementations, see Figure 4 As shown, along the first direction X, the speaker 120 may be located on a side of the fixing bracket 160 facing the projection body 110 , so that the sound outlet 120 a of the speaker 120 corresponds to the avoidance hole 140 b of the first adjustment seat 140 .

[0091] In some embodiments, the fixing bracket 160 may be provided with a wiring groove 160a extending toward the projection body 110. One end of the connection line 130 is connected to the speaker 120, and the other end may be connected to the projection body 110. At least part of the connection line 130 may be located in the wiring groove 160a.

[0092] In the embodiment of the present application, by providing a wiring groove 160a on the fixed bracket 160, a wiring space can be provided for the connecting wire 130, and the side wall of the wiring groove 160a can also be used to provide a wiring path for the connecting wire 130, so that the connecting wire 130 can be wired along the wiring path provided by the wiring groove 160a to connect with the projection body 110. The wiring groove 160a can make the connecting wire 130 neatly arranged on the fixed bracket 160, reduce the possibility of the connecting wire 130 being entangled with the fixed bracket 160 or other structures in the first connection seat, causing the connecting wire 130 to be pulled and affecting the connection reliability of the projection body 110 and the speaker 120.

[0093] In some possible implementations, see Figure 4 As shown, the first adjustment seat 140 can be rotatably connected to the projection body 110 via the first rotating shaft 170. The first rotating shaft 170 can be provided with a threading hole 170a, so that the connecting wire 130 can be passed through the threading hole 170a to be connected to the projection body 110.

[0094] In the embodiment of the present application, when the projection device 100 is placed on a lower horizontal plane, the projection body 110 is disposed above the second adjustment seat 150 through the first adjustment seat 140. The first adjustment seat 140 can be configured to adjust the pitch angle of the projection body 110 by rotating the first rotating shaft 170.

[0095] Therefore, when the projection device 100 is placed horizontally, the user can adjust the position of the projection body 110 in the horizontal direction by adjusting the first adjustment seat 140 to rotate relative to the second adjustment seat 150; by operating the projection body 110 to rotate relative to the first adjustment seat 140 around the first rotation axis 170, the pitch angle of the projection body 110 can be adjusted to meet the visual requirements of the image projected by the projection device 100.

[0096] In some examples, the projection body 110 may emit a light beam toward a screen or a wall along the second direction Y to project an image. It should be noted that the light beam emitted by the projection body 110 may diffuse toward the screen or the wall along the second direction Y to present an image satisfying the user's visual effect on the screen or the wall.

[0097] See also Figure 4 As shown, since the projection body 110 is disposed on the first adjustment seat 140 , the pitch angle of the projection body 110 can be less than 360° to prevent the first adjustment seat 140 from blocking the projection port of the projection body 110 .

[0098] In some examples, the connection line 130 between the speaker 120 and the projection body 110 can be routed along the wiring groove 160a of the fixing bracket 160 and passed through the threading hole 170a on the first rotating shaft 170 to enter the housing 111 of the projection body 110, thereby being electrically connected to the projection module located in the housing 111. Since the pitch angle is less than 360°, the projection body 110 is adjusted within a certain range. Therefore, during the process of adjusting the pitch of the projection body 110, the twisting angle of the connection line 130 is small, which is conducive to reducing the possibility of poor connection between the connection line 130 and the projection body 110 and the speaker 120 during the process of adjusting the pitch angle of the projection body 110.

[0099] In some possible implementations, see Figure 6 As shown, the first adjustment seat 140 can be rotatably connected to the second adjustment seat 150 via the second rotating shaft 200 .

[0100] In some examples, the axial direction of the second rotating shaft 200 may be the same direction as the first direction X. The second adjustment seat 150 may be a disc structure.

[0101] In some embodiments, along the first direction X, the first adjustment seat 140 and the projection body 110 may be located on the same side of the second adjustment seat 150. When adjusting the rotation angle of the first adjustment seat 140 relative to the second adjustment seat 150, the first adjustment seat 140 and the projection body 110 located on the same side of the second adjustment seat 150 may move synchronously, and at this time, the connecting line 130 may also move synchronously with the first adjustment seat 140 and the projection body 110, thereby reducing the possibility that the connecting line 130 is subjected to twisting, pulling, and other forces, which may affect the connection stability between the projection body 110 and the speaker 120.

[0102] Figure 7 The exploded structure of the speaker 120 and the fixing bracket 160 provided in the embodiment of the present application is schematically shown. Figure 8 A schematic diagram of a partial cross-sectional structure of a projection device 100 provided in an embodiment of the present application. Fig. 9 for Figure 8 Schematic diagram of the enlarged structure at point A in the middle. Fig.10 This is a schematic diagram of the structure in which the speaker 120 and the shock absorbing member 190 provided in an embodiment of the present application are connected in cooperation.

[0103] In some possible implementations, see Figures 7 to 10 As shown, the projection device 100 may include a fixing column 161 and a connecting member 180. The fixing column 161 may be disposed on the fixing bracket 160. The connecting member 180 may fix the speaker 120 to the fixing column 161.

[0104] The fixing column 161 of the embodiment of the present application can be configured to support the speaker 120. In addition, the fixing column 161 can reduce the contact area between the speaker 120 and the fixing bracket 160, so as to reduce the possibility of rigid collision between the fixing bracket 160 and the speaker 120 during the vibration of the speaker 120, thereby affecting the playback effect.

[0105] In some embodiments, the projection device 100 may further include a shock absorbing member 190 . Part of the shock absorbing member 190 may be located between the speaker 120 and the fixing column 161 , and part of the shock absorbing member 190 may be located between the speaker 120 and the connecting member 180 .

[0106] The shock absorber 190 of the embodiment of the present application can be configured to absorb at least part of the vibration generated by the speaker 120. Specifically, during the vibration of the speaker 120, the shock absorber 190 can absorb part of the vibration generated by the speaker 120 to avoid a rigid connection between the speaker 120 and the connecting member 180 or the fixing column 161, and reduce the possibility of a rigid collision between the fixing bracket 160 and the speaker 120 causing an abnormal sound, thereby affecting the broadcasting effect. In addition, the shock absorber 190 absorbs part of the vibration generated by the speaker 120, which can reduce the vibration generated by the speaker 120 being transmitted to the fixing bracket 160 through the fixing column 161, and then transmitted to the projection body 110 by the fixing bracket 160, thereby reducing the impact of the vibration of the speaker 120 causing the projection body 110 to shake, and the image projected by the projection body 110 also shaking.

[0107] For some examples, see Figure 3 , Figure 8 and Fig. 9 As shown, the connecting member 180 may be a locking member. The connecting member 180 may lock the speaker 120 on the fixing column 161 of the fixing bracket 160. The connecting member 180 and the fixing column 161 may be threadedly connected.

[0108] In some examples, since the speaker 120 may generate vibrations during operation, a rigid structure may be avoided within a certain range around the speaker 120 to reduce the possibility of the vibration of the speaker 120 colliding with the rigid structure, or the rigid structure hindering the vibration of the speaker 120 and affecting the playback effect.

[0109] For example, no rigid structure may be provided in the space of more than 3 mm around the speaker 120, or a flexible structure may be arranged to prevent direct collision between the speaker 120 and the rigid structure. When the projection device 100 is hung upside down on a ceiling or a wall, the space reserved around the speaker 120 to avoid the rigid structure may be greater than or equal to 4 mm.

[0110] In some examples, the shock absorber 190 can be made of a material that can produce elastic deformation, such as rubber.

[0111] In some possible implementations, see Figure 8 and Fig. 9 As shown, along the first direction X, the surface of the shock absorbing member 190 connected to the connecting member 180 may be protrudingly provided with a first shock absorbing protrusion 191. The surface of the shock absorbing member 190 connected to the fixing column 161 may be protrudingly provided with a second shock absorbing protrusion 192.

[0112] In the embodiment of the present application, the first shock-absorbing protrusion 191 can provide a buffer gap for the vibration of the speaker 120 along the first direction X to the projection body 110, and the second shock-absorbing protrusion 192 can provide a buffer gap for the vibration of the speaker 120 along the first direction X to the fixed column 161. Therefore, during the vibration of the speaker 120, the first shock-absorbing protrusion 191 and the second shock-absorbing protrusion 192 can produce compression deformation, so that the vibration of the speaker 120 is not easily transmitted to the fixed bracket 160, thereby reducing the shaking of the image projected by the projection body 110. In addition, it is easy to understand that the first shock-absorbing protrusion 191 and the second shock-absorbing protrusion 192 are compressed, and it is not easy to hinder the vibration generated during the operation of the speaker 120, so as to ensure the playback effect of the speaker 120.

[0113] In some examples, there may be a plurality of fixing posts 161. Correspondingly, the speaker 120 may be provided with fixing holes corresponding to the fixing posts 161. The fixing holes may be provided near the outer edge of the speaker 120. The plurality of fixing posts 161 may be spaced and evenly distributed along the circumference of the speaker 120.

[0114] In some examples, a reserved notch may be provided on the peripheral side of the speaker 120 to be configured as a wiring space for the connection wire 130 .

[0115] In some possible implementations, see Fig. 9 As shown, the speaker 120 may have a first mounting surface 121 and a second mounting surface 122 that are opposite to each other along a first direction X. The first mounting surface 121 may be configured to be connected to the connector 180 . The second mounting surface 122 may be configured to be connected to the fixing column 161 .

[0116] In some embodiments, the shock absorbing member 190 may include a first shock absorbing portion 193 and a second shock absorbing portion 194. The first shock absorbing protrusion 191 may be disposed on the first shock absorbing portion 193. The second shock absorbing protrusion 192 may be disposed on the second shock absorbing portion 194.

[0117] In some examples, the number of the first shock absorbing protrusion 191 and the number of the second shock absorbing protrusion 192 can be plural. The plurality of first shock absorbing protrusions 191 can be evenly distributed on the first shock absorbing portion 193. The plurality of second shock absorbing protrusions 192 can be evenly distributed on the second shock absorbing portion 194.

[0118] In some examples, the surface of the first shock-absorbing protrusion 191 in contact with the first connecting member 180 may be a spherical surface. The size of the first shock-absorbing protrusion 191 protruding from the first shock-absorbing portion 193 may range from 0.5 mm to 0.7 mm. The surface of the second shock-absorbing protrusion 192 in contact with the second connecting member 180 may also be a spherical surface. The size of the second shock-absorbing protrusion 192 protruding from the second shock-absorbing portion 194 may range from 0.5 mm to 0.7 mm.

[0119] Taking the size range of the first shock absorbing part 193 as 0.5mm to 0.7mm as an example, when the size of the first shock absorbing part 193 is too small, the shock absorbing effect of the first shock absorbing part 193 is insufficient, and the vibration generated by the speaker 120 is easily transmitted to the projection body 110 through the fixing bracket 160, so that the playback image is easily shaken. If the size of the first shock absorbing part 193 is too large, it is easy to occupy the avoidance space around the speaker 120.

[0120] In some embodiments, the first shock absorbing portion 193 may be disposed on the first mounting surface 121 to indirectly connect the connector 180 to the first mounting surface 121. The second shock absorbing portion 194 may be disposed on the second mounting surface 122 to indirectly connect the second mounting surface 122 to the connector 180.

[0121] In the embodiment of the present application, the connecting member 180 and the first mounting surface 121 may be flexibly connected via the first shock absorbing portion 193. The connecting member 180 and the second mounting surface 122 may be flexibly connected via the second shock absorbing portion 194. Therefore, the first shock absorbing portion 193 and the second shock absorbing portion 194 may absorb part of the vibration generated during the operation of the speaker 120, thereby reducing the possibility that the vibration of the speaker 120 is transmitted to the projection body 110 through the fixing column 161 and the fixing bracket 160, causing the image projected by the projection body 110 to shake, thereby affecting the user experience.

[0122] In some embodiments, the shock absorbing member 190 may further include a shock absorbing sleeve 195. The shock absorbing sleeve 195 may connect the first shock absorbing portion 193 and the second shock absorbing portion 194. Along the radial direction of the fixing column 161, the shock absorbing sleeve 195 may indirectly connect the fixing column 161 to the inner wall of the mounting hole 120b of the speaker 120.

[0123] Specifically, during operation, the speaker 120 can generate vibrations along the first direction X and can also generate vibrations along the circumference of the speaker 120. Therefore, the shock-absorbing sleeve 195 of the shock-absorbing member 190 can buffer part of the vibrations generated along the circumference of the speaker 120, thereby avoiding the possibility of a rigid collision between the fixing column 161 and the inner wall of the mounting hole 120b of the speaker 120, thereby affecting the playback effect of the speaker 120.

[0124] In some possible implementations, see Figure 3 and Figure 8 As shown, the first adjustment seat 140 may include a first shell 141 and a second shell 142. The first shell 141 and the second shell 142 may be arranged to form a receiving space 140a.

[0125] In some examples, the fixing bracket 160 may be located in the receiving space 140 a formed by the first shell 141 and the second shell 142 , so that the fixing bracket 160 is not easily exposed.

[0126] In some embodiments, see Fig. 9 and Fig.10 As shown, the projection device 100 may further include a support column 162. The support column 162 may be disposed on the fixing bracket 160. The support column 162 may pass through the speaker 120 to be connected to the first housing 141.

[0127] The end surface of the support column 162 in the embodiment of the present application, which is away from the fixing bracket 160 , may abut against the first shell 141 to support the first shell 141 .

[0128] In some examples, the speaker 120 may be provided with a through hole 120c corresponding to the support column 162. The through hole 120c may be provided close to the sound outlet 120a of the speaker 120. There may be a plurality of through holes 120c. The through hole 120c may correspond to the support column 162.

[0129] The support column 162 can be provided to support the area of ​​the first shell 141 close to the sound outlet 120a, thereby reducing the possibility of collapse or deformation of the area of ​​the first shell 141 close to the sound outlet 120a due to slight external force.

[0130] In some embodiments, the fixing bracket 160 may include a support arm 163. The support arm 163 is connected to the projection body 110 to be configured to support the projection body 110. The first housing 141 may include a first cantilever 1411. The second housing 142 may include a second cantilever 1421. The support arm 163 may be located between the first cantilever 1411 and the second cantilever 1421.

[0131] In some examples, the support arm 163 can be connected to the first cantilever 1411 and the second cantilever 1421 by a fastener so that the fixed bracket 160 forms a whole with the first shell 141 and the second shell 142, so that the fixed bracket 160 and the first adjustment seat 140 and the projection body 110 can move synchronously relative to the second adjustment seat 150.

[0132] In some examples, the fixing bracket 160 may include two supporting arms 163 that are opposite to each other along the third direction Z. The two supporting arms 163 may be rotatably connected to two opposite sides of the projection body 110 along the third direction Z.
