Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present application more clear, the technical solutions of the embodiments of the present application are described in further detail below, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In the description of the present application, unless explicitly stated and limited otherwise, the terms "connected," "secured" and "fixed" are to be construed broadly, as for example, they may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated between two elements or the interaction relationship between the two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In this application, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact with each other by way of additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.

In the terminal device in the prior art, if the display of images and the playing of sound are to be realized, a plurality of hole sites are generally arranged on a speaker module, a corresponding number of threaded holes are arranged on a backboard of a display screen, and then the speaker module is fixedly arranged on the backboard of the display screen by being matched and connected with the hole sites and the threaded holes through screws and gaskets. Because the installation process of the loudspeaker module and the display screen needs to align the hole position with the threaded hole, and the screw is screwed in place one by one when the screw is screwed, the installation efficiency of the loudspeaker and the display device is low.

In order to solve the problem of low installation efficiency of a speaker and a display device in the prior art, as shown in fig. 1, 2 and 3, the present embodiment provides a speaker fixing structure, including:

a speaker body 1 having a mounting hole 11;

an elastic connection member 2 having a protrusion 211 at one end surface and a cavity 231 at the other end surface;

a mounting surface 3 having a connection hole 31, the connection hole 31 for receiving the protrusion 211;

the casing 4 is fixedly arranged on the mounting surface 3, the casing 4 is provided with a containing cavity 41, the containing cavity 41 can contain the loudspeaker body 1 and the elastic connecting piece 2, the cavity bottom of the containing cavity 41 is convexly provided with a connecting rod 42, and the connecting rod 42 is used for plugging the concave cavity 231 so as to fixedly arrange the loudspeaker body 1 and enable the loudspeaker body 1 to be arranged at intervals with the mounting surface 3 and the wall surface of the casing 4.

By providing the mounting hole 11 on the speaker body 1, the elastic connection member 2 is provided in the mounting hole 11. Since one of the end surfaces of the elastic connection member 2 has the protrusion 211 and the mounting surface 3 has the connection hole 31, the protrusion 211 of the elastic connection member 2 can be disposed in the connection hole 31, thereby spacing-fixing one end of the elastic connection member 2 through the mounting surface 3.

Meanwhile, the housing 4 is provided with a containing cavity 41 capable of containing the speaker body 1 and the elastic connecting piece 2, the connecting rod 42 is convexly arranged at the bottom of the containing cavity 41, and the other end face of the elastic connecting piece 2 is provided with a concave cavity 231, so that the connecting rod 42 and the concave cavity 231 can be correspondingly arranged to limit and fix the other end of the elastic connecting piece 2. Further, since the housing 4 is fixedly provided to the mounting surface 3, the elastic connector 2 can be held by the housing 4 and the mounting surface 3, and the speaker body 1 can be fixedly provided.

Therefore, the speaker fixing structure of the present application clamps the elastic connection member 2 through the housing 4 and the mounting surface 3, and can fix the speaker body 1 provided on the elastic connection member 2 on the premise of avoiding direct contact with the speaker body 1. Since the elastic connection member 2 has elastic deformation capability and vibration buffering capability, after the vibration generated when the speaker body 1 works by sounding is transmitted to the elastic connection member 2, the vibration can be absorbed and buffered by the elastic connection member 2, so that the vibration generated by the speaker body 1 is transmitted to the mounting surface 3 and the housing 4 to cause vibration damage to the display device 9, and the service life of the display device 9 can be prolonged.

Preferably, the housing 4 has a function of wrapping and protecting elements such as a hardware main board, a screen driving board, and an internal wire, in addition to the speaker body 1.

For an example structure of the elastic connection member 2, optionally, referring to fig. 4, the elastic connection member 2 has a first stopper section 21, a connection post 22, and a second stopper section 23, which are sequentially provided. The connecting column 22 is arranged in the mounting hole 11, the first limiting section 21 and the second limiting section 23 at the two ends of the elastic connecting piece 2 are respectively abutted against the two sides of the mounting hole 11, and the connecting column 22 can be limited to be separated from the mounting hole 11 through the first limiting section 21 and the second limiting section 23. Correspondingly, the end surface of the first limiting section 21 has a protrusion 211, and the end surface of the second limiting section 23 has a concave cavity 231 to be respectively connected to the connection hole 31 and the connection rod 42.

When the loudspeaker body 1 is installed and fixed, the first limiting section 21 of the elastic connecting piece 2 can be plugged into the installation hole 11 of the loudspeaker body 1, and the first limiting section 21 can elastically deform, so that the connecting column 22 is arranged in the installation hole 11 after the first limiting section 21 passes through the installation hole 11, and the first limiting section 21 is restored to the original shape. At this time, the first limiting section 21 and the second limiting section 23 are respectively disposed at two ends of the mounting hole 11, and the edges of the mounting hole 11 are abutted by the first limiting section 21 and the second limiting section 23, so that the connection post 22 can be limited to be separated from the mounting hole 11, and the elastic connection piece 2 is kept in clamping connection with the speaker body 1. The protrusion 211 of the elastic connector 2 is inserted into the connection hole 31 of the mounting surface 3, and the connecting rod 42 of the housing 4 is inserted into the cavity 231 of the elastic connector 2, so that the elastic connector 2 can be fixed between the housing 4 and the mounting surface 3. Finally, the shell 4 is fixedly arranged on the mounting surface 3, so that the elastic connecting piece 2 and the loudspeaker body 1 fixedly arranged on the elastic connecting piece 2 are clamped and fixed, and the loudspeaker body 1 is prevented from being in direct contact with the shell 4 and the mounting surface 3.

In addition, the mounting holes 11 may be provided only at both ends of the speaker body 1 in the diagonal direction, and correspondingly, the case 4 may be provided with two connection rods 42, and the mounting surface 3 may be provided with two connection holes 31. The elastic connector 2 in the mounting hole 11 is clamped by the housing 4 and the mounting surface 3, so that the translation and rotation of the loudspeaker can be limited, and the fixing effect is realized. In order to promote the alignment connection between the speaker body 1 and the mounting surface 3, mounting holes 11 may be provided at four corners of the speaker, correspondingly, four connection holes 31 may be provided on the mounting surface 3, and the protrusions 211 of the elastic connection member 2 in the mounting holes 11 are used to correspond to the plug connection holes 31, so as to improve the accuracy of the mounting positions of the speaker body 1 and the mounting surface 3. However, the housing 4 may still adopt two connecting rods 42 corresponding to the diagonal lines, and the speaker body 1 may be limited and fixed only by clamping the elastic connecting piece 2 of the speaker body 1 located on the diagonal line, so as to avoid the excessive positioning and reduce the installation efficiency.

In particular, referring to fig. 4, at least one annular groove 212 is provided at a side surface of the first limiting section 21, and when the first limiting section 21 is axially compressed, an elastic deformation section of the first limiting section 21 can be increased by the annular groove 212, thereby increasing a vibration absorbing capacity of the elastic connection member 2. When the number of the annular grooves 212 increases, the elastic deformation range of the first limiting section 21 also increases, but the larger the elastic deformation range is, the greater the risk that the speaker body 1 contacts the housing 4 and the mounting surface 3 increases. Therefore, the actual number of the annular grooves 212 may be determined according to the actual deformation requirement, and the present embodiment is not particularly limited.

Further, when the number of the annular grooves 212 is greater than two, the two adjacent annular grooves 212 are spaced apart, so that the structural strength of the first limiting section 21 can be prevented from being excessively weakened, and the supporting performance of the first limiting section 21 can be maintained. In a preferred embodiment, the spacing between adjacent annular grooves 212 is the same to maintain the uniformity of elastic deformation of the first stop segment 21.

Still preferably, referring to fig. 4, rounded transition structures are provided at the walls and notches of the annular recess 212. On one hand, stress concentration on the surface of the first limiting section 21 is reduced, and the risk of fracture of the first limiting section 21 is reduced; on the other hand, the first limiting section 21 is also convenient to be inserted into the mounting hole 11, so that the friction resistance between the annular groove 212 and the mounting hole 11 is reduced.

Alternatively, referring to fig. 4, the width of the end of the first limiting section 21 away from the second limiting section 23 may be made smaller than the width of the end near the second limiting section 23, so as to insert the end of the first limiting section 21 into the mounting hole 11. When the first limiting section 21 is inserted into the mounting hole 11, the efficiency of penetrating the first limiting section 21 through the mounting hole 11 can be improved, and the resistance of the first limiting section 21 penetrating through the mounting hole 11 can be reduced.

Preferably, referring to fig. 1 and 2, the wall of the mounting hole 11 is provided with a slot 12, and the slot 12 can accommodate the deformed connecting post 22. On the one hand, the connecting column 22 arranged behind the mounting hole 11 can overflow into the slot 12 during extrusion deformation, and the elastic deformation section of the connecting column 22 is lifted, so that the vibration buffering performance of the elastic connecting piece 2 is improved; on the other hand, when the elastic connector 2 is mounted in the mounting hole 11, the connecting column 22 can be crushed in the radial direction and then plugged into the slot 12, so that the connecting slot can be moved into the mounting hole 11 along the slot 12, and the mounting efficiency of the elastic connector 2 and the loudspeaker body 1 can be improved.

Further, referring to fig. 4, the cavity bottom of the cavity 231 is provided with a blind hole 24, and the blind hole 24 extends to the first limiting section 21. The blind holes 24 can enlarge the elastic deformation space of the elastic connecting piece 2, so that the connecting column 22 can be extruded into the slot 12 in a plate shape, and can be restored into a column shape after reaching the mounting hole 11, thereby improving the mounting efficiency of the elastic connecting piece 2 and the mounting hole 11.

For the preferred structure of the connecting rod 42 of the housing 4, a threaded hole may be provided at a position of the housing 4 corresponding to the connecting rod 42, the connecting rod 42 is a bolt, and the screw thread of the bolt is connected to the threaded hole, so that the distance between the end of the screw and the cavity 231 can be adjusted by driving the screw to rotate. Pressure can be provided to the resilient connecting element 2 by driving the screw to rotate towards the resilient connecting element 2.

In a preferred embodiment, referring to fig. 3, a convex hull 33 is provided on the mounting surface 3, a cavity is provided in the convex hull 33, and a connection hole 31 is concavely provided on the surface of the convex hull 33, so that the protrusion 211 can be accommodated by the cavity, the protrusion 211 is prevented from protruding from the bottom of the mounting surface 3, and the protrusion 211 can be prevented from occupying the space below the mounting surface 3. The convex hull 33 of the present embodiment is not only used for carrying the elastic connection member 2, but also for avoiding the contact between the speaker body 1 and the mounting surface 3, so that the distance between the speaker body 1 and the mounting surface 3 is an amplitude gap, and the distance between the speaker body 1 and the mounting surface 3 can be maintained when the speaker body 1 vibrates. For a preferred height of the convex hull 33, it may be 3mm.

In particular, referring to fig. 5, the mounting surface 3 is convexly provided with the positioning post 32, correspondingly, the housing 4 is provided with the positioning hole 43, and the positioning post 32 is correspondingly connected with the positioning hole 43, so that the connection strength of the housing 4 and the mounting surface 3 can be further improved, and the risk of twisting the housing 4 relative to the mounting surface 3 is reduced.
