According to an embodiment of the present invention, there is provided a speaker apparatus. The device comprises a housing, a base 15 and an elastic connection. Either one of the base 15 and the housing has a through hole 18, a first cambered surface 16 is provided around the outer periphery of the through hole 18, and the other one of the two has an abutment portion that mates with the first cambered surface 16. For example, the through holes 18 may be circular, elliptical, or polygonal in shape to meet different usage requirements. For example, the first cambered surface 16 is a concave cambered surface or a convex cambered surface. The first cambered surface 16 may be an arc surface, an elliptical cambered surface or a cambered surface with any radian set according to needs, so long as the relative angle between the base 15 and the housing can be changed.

The elastic connection portion passes through the through hole 18 and connects the base 15 and the housing. For example, the elastic connection is an elastic rubber member or an assembly of a plurality of parts of different functions.

The aperture of the through hole 18 is larger than the outer diameter of the elastic connection portion. In this way, there is enough freedom between the base 15 and the housing to change the relative angle, and the elastic connection does not form an interference with the base 15 or the housing. The elastic connection portion is configured to form an elastic force directed toward the housing by the base 15 so that the abutment portion abuts against the first cambered surface 16, and the abutment portion can slide along the first cambered surface 16. For example, the abutting portion may be a second arc surface 26, a plurality of arc surfaces arranged at intervals, or a ring structure, as long as the abutting portion can abut against the first arc surface 16 and slide along the first arc surface 16 to change the relative angle between the base 15 and the housing.

For example, the base 15 has a through hole 18, a first arcuate surface 16 is provided around the outer periphery of the through hole 18, and an abutment is provided on the housing. The abutment portion abuts against the first cambered surface 16 and can slide along the first cambered surface 16.

For example, the housing has a through hole 18, a first arcuate surface 16 is provided around the outer periphery of the through hole 18, and an abutment is provided on the base 15. The abutment portion abuts against the first cambered surface 16 and can slide along the first cambered surface 16.

In the speaker device of the present invention, the first cambered surface 16 is in contact with the contact portion and can slide relatively, so that the setting angle between the base 15 and the housing can be changed. Therefore, the direction of the loudspeaker can be adjusted according to different installation positions, so that the sound effect of the device is good. The adaptation of the loudspeaker device is improved.

In addition, the elastic connection portion can form an elastic force directed to the housing by the base 15 so that the abutment portion abuts against the first cambered surface 16. In this way, the angle between the base 15 and the housing changes due to the change in the contact position of the contact portion with the first cambered surface 16.

In addition, the elastic force forms friction between the base 15 and the housing, so that the angle between the base 15 and the housing can be fixed.

Fig. 1 is an exploded view of a speaker apparatus according to one embodiment of the present invention. Fig. 2 is a cross-sectional view of a speaker apparatus according to one embodiment of the present invention. Fig. 3 is a cross-sectional view of a speaker apparatus rotated by a set angle according to an embodiment of the present invention.

As shown in fig. 1, the housing includes a front cover 11 and a bottom cover 13 that snap together. The front cover 11 has sound outlets. The bottom case 13 is for connection with the base 15. The interior of the housing forms a cavity. The speaker unit 12 is disposed in the cavity and opposite the sound outlet. A circular through hole 18 is provided in the base 15, and a first cambered surface 16 surrounding said through hole 18. The first cambered surface 16 is a convex cambered surface. As shown in fig. 2, the bottom case 13 is provided with an abutting portion, which is a second arc surface 26 that matches the first arc surface 16. The second cambered surface 26 is a concave cambered surface. The first cambered surface is a 16-bit concave cambered surface, and the second cambered surface is a convex cambered surface. In this way, the relative sliding between the first cambered surface 16 and the second cambered surface 26 is smoother, and the rotating operation is more labor-saving.

In addition, the first cambered surface 16 and the second cambered surface 26 have larger contact area, the pressure intensity of the two cambered surfaces is small, the two cambered surfaces are not easy to damage, and the service life is long.

Optionally, a damping coating is applied to at least one of the first and second cambered surfaces 16, 26. The damping paint can increase the friction between the two cambered surfaces, so that the rotating angle of the base 15 and the bottom shell 13 can be fixed.

In one example, a guide rail extending in the set direction is provided on either the first cambered surface 16 or the abutting portion, and a groove matching the guide rail is provided on the other, and the guide rail 17 is inserted into the groove to define the direction in which the housing and the base rotate. For example, the set direction is a direction in which the bottom case 13 and the base 15 relatively rotate. As shown in fig. 1-3, the first cambered surface 16 is located on the base 15, and the guide rails are arranged on both sides of the through hole 18 in the rotation direction. The height of the guide rail can be set by a person skilled in the art according to actual needs. A groove is provided on the second cambered surface 26. The guide rail 17 is inserted into the groove during assembly. The grooves form a definition of the guide rail 17. During rotation, the bottom shell 13 and the base 15 can only rotate in the extending direction of the guide rail 17. In this way, the angle between the bottom shell 13 and the base 15 is adjusted more accurately, and the two are prevented from being displaced randomly.

Of course, the guide rail 17 may be provided on the abutting portion (for example, the second cambered surface 26), and the groove may be provided on the first cambered surface 16, as long as the rotation direction can be defined.

In one example, the elastic connection is an assembly of multiple pieces. For example, the elastic connection includes an elastic element and a pin 22. The elastic member is used to provide elastic force, and the pin 22 is used to connect the housing with the base 15. One end of the pin 22 is connected to the housing and the other end is connected to the base 15. The pin 22 passes through the through hole 18. The bore diameter of the through hole 18 is larger than the outer diameter of the pin 22. The elastic element is located between the end of the pin 22 and the housing or between the end of the pin 22 and the base 15. The length of the pin 22 is such that there is axial freedom between the housing and the base 15 to facilitate angular adjustment and assembly of the speaker. For example, as shown in fig. 7, both ends of the pin 22 have the engaging portions 23. As shown in fig. 1-3, the clamping portion 23 of the pin 22 forms a clamping connection with the base 15 and the bottom shell 13, respectively. This structure facilitates the assembly of the speaker device.

As shown in fig. 2 to 3, the bottom case 13 is allowed to move in the radial direction of the pin 22 during rotation because the aperture of the through hole 18 is larger than the outer diameter of the pin 22. Since the abutting portion abuts against the first cambered surface 16, the position of the bottom shell 13 with respect to the first cambered surface 16 changes. The change of position changes the angle of the bottom shell 13 relative to the base 15, and angle adjustment is achieved.

Preferably, at least one of the housing and the base 15 is removably connected to the pin 22. This facilitates the connection of the housing to the base 15 and makes the assembly of the loudspeaker device simpler. For example, the engagement portion 23 is screwed with the pin body 27. During installation, the clamping part 23 and the pin shaft main body 27 are firstly loosened; then, the pin body 27 passes through the bottom case 13 and the base 15; the engaging portion 23 is then screwed with the pin body 27.

In one example, the elastic element is a spring 19. The spring 19 includes a ring 21 and a plurality of spring arms 20 connected to the ring 21. Spring arms 20 are used to form a spring force. Each spring arm 20 is connected to the ring 21 and extends outwardly, the spring arms 20 forming stops with the housing or base 15. The pin 22 passes through the inner ring of the ring 21. For example, the plurality of spring arms 20 are uniformly arranged around the ring 21. During assembly, the elastic sheet 19 is pressed by the clamping part 23 of the pin 22, and elastic deformation occurs between the elastic arm 20 and the annular piece 21 to form a force for making the bottom shell 13 close to the base 15. The spring 19 has simple structure, convenient assembly and good elasticity.

Preferably, as shown in fig. 8, the spring arms 20 are 2 and are oppositely disposed on both sides of the ring 21. This saves material and the spring 19 has sufficient spring force. Alternatively, two spring arms 20 are respectively opposite to the two guide rails 17. In this way, the spring piece 19 has a sufficient spring force in the rotational direction. Preferably, the elastic sheet 19 is an arc surface structure, and the arc surface structure is the same as the protruding direction of the first arc surface 16. In this way, the pin 22 can be made shorter and the spring force is more directional.

For example, as shown in fig. 7, a stepped boss 24 is provided on the pin body 27. The outer diameter of the stepped boss 24 is the same as that of one of the engagement portions 23. For example, the outer diameter of the pin body 27 is the same as the inner diameter of the ring 21. In this way, the clip portion 23 can pass through the ring member 21 to facilitate assembly of the spring piece 19, and the ring member 21 can be fitted over the stepped boss 24. Since the outer diameter of the step-shaped protrusion 24 is the same as the inner diameter of the ring-shaped member 21, the step-shaped protrusion 24 can prevent displacement between the elastic sheet 19 and the pin 22 when the housing and the base 15 rotate relatively, so that the elastic force between the base 15 and the housing is stable.

Fig. 4 is an exploded view of a speaker apparatus according to another embodiment of the present invention. Fig. 5 is a schematic structural view of a speaker apparatus according to another embodiment of the present invention. Fig. 6 is a schematic structural view of a speaker apparatus rotated by a set angle according to another embodiment of the present invention.

As shown in fig. 4 to 6, a wavy bulge 25 arranged in the rotation direction is provided on either one of the base 15 and the housing, and a bump 14 engaged with the wavy bulge 25 is provided on the other of the two, the wavy bulge 25 and the bump 14 forming a damping gear effect. For example, the damping gear effect means that the wavy bulge 25 is engaged with the convex point 14, and the convex point 14 slides along the peak and the valley of the wavy bulge 25 when rotating, forming a jerk feel similar to when shifting gears, and when rotating to a proper angle, the convex point 14 is blocked into the valley of the wavy bulge 25, forming a fixation of the angle. In this way, the adjustment of the angle between the housing and the base 15 can be made more precise and the relative position between the two more fixed. In addition, the damping gear effect improves the user experience.

Preferably, the bump 14 is plural and arranged in the rotational direction. The arrangement of the plurality of protruding points 14 can enable the relative position between the base 15 and the shell to be more fixed, and the offset of the relative angle between the shell and the base 15 is effectively avoided.
