All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence of the functions performed by the devices, modules or units.

Referring to fig. 1 and 2, an embodiment of the present disclosure provides a sound box 100. The sound box 100 is an acoustic structure in the projector 200. Projector 200 also includes a housing 201. The sound box 100 includes a sound emitting assembly 10, a support 20, and a connecting assembly 30. The support 20 is fixedly connected to the housing 201. The sound producing component 10 is provided with a sound cavity 11. The number of the connecting members 30 is three, and each connecting member 30 includes one buffer member 31 and one connecting member 33. The buffer member 31 abuts against the sound generating assembly 10 and the support 20 along the axial opposite ends of the first connecting hole 12, so as to isolate the sound generating assembly 10 from the support 20, and prevent the sound generating assembly 10 from contacting the support 20. The buffer member 31 is made of a silicone material, and the buffer member 31 can elastically deform, so that the abutting force of the buffer member 31 on the sounding component 10 and the support 20 is an elastic force. It is understood that in other embodiments, the buffer 31 may also be a spring, a composite structure of metal and plastic, etc. having a structure at least partially elastically deformable.

It is understood that in other embodiments, the sound box 100 may be a stand-alone sound structure, or may also be a sound of an electronic device such as a television, a computer, etc.

The support 20 and the housing 201 in this embodiment are fixedly connected by fasteners such as screws, and in other embodiments, the support 20 and the housing 201 may also be of an integral structure.

The sound emitting assembly 10 is provided with a first connection hole 12 at the outside of the sound chamber 11. The support 20 is provided with a second coupling hole 211. The connecting member 33 passes through the second connecting hole 211 and the first connecting hole 12 in sequence, and abuts against two opposite sides of the sound generating assembly 10 and the support 20, so as to clamp and fix the sound generating assembly 10 and the support 20. The connecting member 33 is made of a silicone material, and the connecting member 33 is an elastically deformable structure, so that the abutting force of the connecting member 33 on the sounding component 10 and the support 20 is an elastic force.

The sound box 100 is supported between the sound generating assembly 10 and the support 20 through the buffer member 31, so that the sound generating assembly 10 is isolated from the support 20, and supported on two sides of the sound generating assembly 10 opposite to the support 20 through the connecting member 33 to clamp the fixed support 20 and the sound generating assembly 10, so that the force applied to the support 20 and the sound generating assembly 10 by the connecting member 30 (the buffer member 31 and the connecting member 33) is elastic, the support 20 is elastically connected with the sound generating assembly 10, when the power of a loudspeaker (not shown) in the projector 200 is large and the sound generating assembly 10 vibrates greatly, the elastic connection mode of the connecting member 30 can enable the vibration to be absorbed, the vibration amplitude of the support 20 and the shell 201 is reduced, or the support 20 and the shell 201 can be prevented from vibrating along with the sound generating assembly 10.

When the connecting member 33 is installed from the side of the sound generating assembly 10 away from the support 20, the first groove 14 of the side of the first connecting hole 12 away from the support 20 needs to provide an overall accommodating space for the connecting member 33 (for example, the first groove 14 penetrates through the side of the sound generating assembly 10 away from the support 20) so that the connecting member 33 can pass through the first connecting hole from the first groove 14. When the connecting member 33 is installed from one side of the sound generating assembly facing the support 20, the first groove 14 does not need to provide the whole accommodating space of the connecting member 33, but only needs to provide the space of the part of the connecting member 33, so as to avoid reducing the volume of the sound cavity 11 or increasing the overall volume of the sound generating assembly 10 and the whole size of the sound box 100 on the premise of ensuring the volume of the sound cavity 11.

Referring to fig. 3 and 4, the sounding element 10 is provided with three first connection holes 12, three first grooves 14 and three protrusions 13. The first slot 14 is opened outside the sound chamber 11 and communicates with the first connection hole 12. The first slot 14 is located on the side of the sound chamber 11 facing the support 20. The sound emitting assembly 10 extends toward one side of the support 20 to form a projection 13. The protruding portion 13 is provided with a first through hole 131, and the first through hole 131 communicates with the first connection hole 12. One end of the connection member 33 is elastically deformed and sequentially passes through the first through hole 131 and the first connection hole 12 and is received in the first slot 14. The connecting member 33 received in the first groove 14 has one end restored to its original shape to be stopped on the bottom wall of the first groove 14 and the other end stopped on the support 20.

Connecting piece 33 deviates from one side installation of sound generating component 10 from support 20, and first groove 14 provides the accommodation space of connecting piece 33 through the part of first connecting hole 12, makes the space that first groove 14 deviates from support 20 one side can set up to the partly of sound chamber 11 to increase the volume of sound chamber 11, and then promote the tone quality of projecting apparatus 200.

It will be appreciated that in other embodiments, the connecting member 33 may be mounted from the side of the sound emitting assembly 10 facing away from the support base 20. No matter which direction the connecting member 33 is installed, the connecting member 30 can absorb the vibration of the sound box 100 and reduce the amplitude of the vibration of the sound box by the elastic connection manner of the connecting member 30, or prevent the occurrence of abnormal sound due to the collision between the support 20 and the sound generating member 10 caused by the vibration of the sound box.

It is understood that in other embodiments, the first slot 14 may be omitted. For example, the sound emitting assembly 10 is provided with a boss (not shown) protruding outwards, the first connection hole 12 penetrates through the boss, and one end of the connection member 33 can be received at one side of the boss after passing through the first connection hole 12.

It is understood that in other embodiments, the protrusion 13 may be a structure independent from the sound module 10 and fixedly connected to the sound module 10.

The hole wall of the first through hole 131 of the projection 13 is in contact with the connecting member 33, as shown in fig. 2. The link 33 includes a connection portion 331, a first stopper portion 333, and a second stopper portion 335. The first blocking portion 333 and the second blocking portion 335 are respectively disposed at two ends of the connecting portion 331. The first stopper 333 is elastically deformable and restores its original shape after passing through the first and second coupling holes 12 and 211. The first blocking portion 333 is stopped on the sound emitting assembly 10, and the second blocking portion 335 is stopped on the support 20. The first blocking portion 333 is elastically buckled to the sound component 10 by elastic deformation of itself, so that the installation convenience of the connector 33 is improved.

The connection portion 331 contacts the hole wall of the first through hole 131, positioning the connection member 33 in the radial direction of the first through hole 131. The protrusion 13 provides the connecting member 33 with a supporting force in a radial direction along the first through hole 131, and improves reliability of the connecting member 33 in connecting the sound generating assembly 10 and the support 20.

When the buffer 31 is installed between the sound generating component 10 and the support 20, the distance between the two opposite surfaces of the first blocking portion 333 and the second blocking portion 335 is greater than the dimension of the connecting portion 331 along the axial direction of the first connecting hole 12, so that the connecting member 33 and the buffer 31 are elastically deformed to connect the support 20 and the sound generating component 10, and the vibration amount of the sound generating component 10 along the axial direction of the first connecting hole 12 is controlled by setting the dimension of the connecting portion 331 and the dimension of the buffer 31 along the axial direction of the first connecting hole 12, respectively.

It is understood that in other embodiments, the connecting member 33 may be partially in contact with the hole wall of the first through hole 131, so that the connecting member 33 is positioned in the radial direction of the first through hole 131.

It is understood that in other embodiments, the protrusion 13 may be disposed on the support 20, and the protrusion 13 is spaced apart from the sound emitting assembly 10.

It is understood that in other embodiments, the second blocking portion 335 is a structure capable of being elastically deformed when the connecting member 33 is installed from the side of the support 20 away from the sound emitting assembly 10. The second blocking portion 335 is restored to its original shape after passing through the first connection hole 12, the first through hole 131, and the second connection hole 211 in sequence.

The first blocking portion 333 and the second blocking portion 335 are respectively a conical cylinder structure, and the connecting portion 331 is a circular cylinder structure, but not limited thereto. The first stopper 333 stops a portion on the sounding module 10 at an outer peripheral side of the first connection hole 12. The portion of the second blocking portion 335 stopped on the holder 20 is located at the outer circumferential side of the second coupling hole 211.

Referring to fig. 5, in another embodiment, the connecting member 33a is formed with a second groove 301, and the second groove 301 extends toward the side of the support 20. The second groove 301 penetrates the first stopper 333 and extends to the connecting portion 331. The second groove 301 penetrates the first stopper 333, so that the first stopper 333 is easily deformed to easily pass through the first through hole 131, the first connection hole 12 and the second connection hole 211.

It is understood that in other embodiments, the first blocking portion 333 and the second blocking portion 335 may have other shapes, for example, as shown in fig. 6, in the connecting member 33b, the connecting portion 331b has a square-cylinder structure. The first blocking portion 333b is a trapezoid block structure, and one side of the first blocking portion protrudes from the connecting portion 331b. The second blocking portion 335b has a square block structure, and one side of the second blocking portion protrudes from the connecting portion 331b. The one-sided projecting first stopper portion 333b is easily deformed.

Referring to fig. 7 and 8, the buffer 31 is a circular cylinder structure. The buffer member 31 is provided with a second through hole 311. The projection 13 is located in the second through hole 311. The wall portion of the second through hole 311 is recessed to form a plurality of spaced first grooves 313, and the groove walls of the first grooves 313 are not in contact with the projections 13, so that the projections 13 are in contact with the wall portion of the second through hole 311. The first groove 313 makes the convex portion 13 easily elastically deformed, enhancing the ability of the buffer member 31 to absorb the vibration of the acoustic enclosure 100.

It is understood that in other embodiments, the first groove 313 may be omitted, and the outer peripheral wall of the protrusion 13 may be entirely in contact with the hole wall of the second through hole 311.

The protruding portion 13 is at least partially in contact with the hole wall of the second through hole 311, so that the first protruding portion 13 is positioned in the radial direction of the second through hole 311, the buffer member 31 is prevented from moving due to the large vibration of the sound cavity 11, and the position stability of the buffer member 31 is improved.

The holder 20 is provided with a mounting groove 231. The holder 20 includes a main body 21 and three mounting portions 23.

The mounting groove 231 is opened to the mounting portion 23. The buffer member 31 is received in the mounting groove 231. The peripheral wall portion of the buffer member 31 is recessed to form a plurality of spaced second grooves 315. The groove wall of the second groove 315 is not in contact with the groove wall of the mounting groove 231, so that the buffer member 31 is in contact with the groove wall portion of the mounting groove 231. The second groove 315 facilitates elastic deformation of the protrusion 13, enhances the ability of the buffer member 31 to absorb vibration of the sound box 100, and facilitates mounting of the buffer member 31 between the protrusion 13 and the mount 20. It is understood that in other embodiments, the second recess 315 may be omitted.

The protruding portion 13 and the support 20 are respectively in contact with the buffer member 31, so that the buffer member 31 absorbs vibration in the radial direction of the first through hole 131, the amplitude of vibration of the support 20 and the housing 201 is reduced, or abnormal sound generated by collision between the support 20 and the sound generating assembly 10 due to vibration of the sound box can be avoided.

The sound box 100 controls the vibration amount of the sounding assembly 10 in the radial direction of the first connection hole 12 by setting the size of the buffer 31 in the radial direction of the first connection hole 12.

The first grooves 14 are the same number as the connecting members 30 for receiving the connecting members 33 of the connecting members 30. The number of the first connection holes 12 and the first through holes 131 is the same and equal to the number of the connection members 33. It is understood that, in other embodiments, the number of the connecting assemblies 30 may be two, four, five, etc., and the number of the buffers 31 and the connecting members 33 in each connecting assembly 30 may also be unequal, and may be other numbers respectively. For example, as shown in fig. 9, in another embodiment, the connecting assembly 30a omits the protrusion 13, and the number of the buffers 31a is two, and is located at two opposite sides of the connecting member 33. The mount 20a omits the mounting portion 23, and the mount 20a is partially recessed to form two mounting grooves 231a. A portion of the sound emitting module 10a is recessed to form two more mounting grooves 15. Opposite ends of each cushion member 31a are positioned and received in the mounting grooves 231a and 15 such that the sounding module 10a does not contact the support 20 a.

It is understood that in other embodiments, the connecting element 33 may be made of other materials such as rubber and plastic, or the connecting element 33 may be a composite structure formed by integrally molding metal and rubber, plastic and silicone.

It is understood that in other embodiments, the connecting member 33 may be a non-snap connection.
