Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a novel combined sound column speaker. Background Technology

[0002] A sound column is composed of multiple loudspeakers arranged and connected in phase. The directivity of a sound column is similar to that of a single loudspeaker in the horizontal direction, but it is significantly improved in the vertical direction. It propagates in a wave-like pattern horizontally, but exhibits strong directivity in the vertical direction, creating a "disc"-shaped stereo radiation effect. A speaker enclosure, simply put, refers to a speaker unit or subwoofer enclosure with a built-in power amplifier. This amplifier amplifies the audio signal before it is reproduced by the speaker itself, making the sound louder. To achieve optimal sound quality, multiple audio devices are usually used. However, most existing audio equipment is designed separately, requiring additional components or frames for combined use, making it inconvenient to carry.

[0003] For example, Chinese utility model patent CN 209882052 U discloses a transportable modular speaker system, including a line array speaker, a subwoofer, and a connecting component. The connecting component connects the line array speaker and the subwoofer, hinged together. The top of the subwoofer has a receiving slot that fits the line array speaker. When the modular speaker system needs to be transported, the line array speaker is rotated around the connecting component towards the receiving slot, allowing it to be housed within the subwoofer's receiving slot, thus saving transport space. However, this modular speaker system requires an additional connecting component, making assembly relatively complex. Utility Model Content

[0022] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0023] like Figures 1 to 6The diagram shown is a structural schematic of a novel combined column speaker provided by this utility model. The novel combined column speaker includes a base speaker 10, a telescopic component 20 disposed on one end face of the base speaker 10, and at least one column speaker 30 fixedly disposed on one end face of the telescopic component 20. It is conceivable that the novel combined column speaker also includes other functional structures, such as telescopic fasteners, buffer pads, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0024] The base speaker 10 includes a base frame 11 and a first speaker 12 embedded in the base frame 11.

[0025] A threaded blind hole 13 is provided on one end face of the base frame 11. The threaded blind hole 13 is located in the middle area of ​​the base frame 11 and is connected and fixed to the telescopic component 20.

[0026] The base frame 11 has at least one weight-reducing hole 14 at the end away from the screw blind hole 13, which reduces the overall weight and makes it easier to transport.

[0027] The first speaker 12 is an existing device used to convert audio signals into sound.

[0028] The telescopic assembly 20 includes a telescopic rod assembly 21 with one end fixedly disposed on one end face of the base speaker 10, and a first insertion slot 22 fixedly disposed on the free end of the telescopic rod 21.

[0029] One end of the telescopic rod assembly 21 is threaded and screwed into the threaded blind hole 13, making the telescopic rod 21 and the base frame 11 rigidly connected. The telescopic rod assembly 21 has two interlocking support rods 211, each support rod 211 is provided with multiple adjustment holes 23, and a pin 24 is inserted into the adjustment hole 23 to fix the length of the two support rods 211 after adjustment, thus adapting to different usage scenarios.

[0030] The first insertion slot 22 and the telescopic rod 21 can be connected and fixed by welding or screwing. A first insertion rod 25 is provided at each of the four corners of the bottom surface of the first insertion slot 22. The first insertion rod 25 and the first insertion slot 22 can be integrally cast, or the first insertion rod 25 can be screwed onto the first insertion slot 22.

[0031] The four first plug-in rods 25 are used to plug and fix the column speaker 30. The first plug-in rods 25 are greater than or equal to half the height of the column speaker 30, so that after the column speaker 30 is plugged into the first plug-in slot 22, the four first plug-in rods 23 can support and fix the column speaker 30, and will not sway or even fall off.

[0032] The pillar speaker 30 includes at least one second speaker 31 and a second connector 32 disposed at one end of the second speaker 31. Four connector holes 33 are provided at the four corners of the second speaker 31. The connector holes 33 are through holes and are disposed on the housing of the second speaker 31. The connector holes 33 are used for interlocking with the first connector slot 22 and the second connector slot 22.

[0033] The outer contour of the second speaker 31 is the same as the inner contour of the first insertion slot 22 and the second insertion slot 32. This allows both ends of the second speaker 31 to be fitted into the first insertion slot 22 and the second insertion slot 32.

[0034] Please see Figure 5 The second connector 32 includes two second connector slots 321 located on both sides, and two sets of second connector rods 322 fixedly mounted on the second connector slots 321.

[0035] A second plug rod 322 is provided at each of the four corners of the symmetrical end faces of the second plug-in component 32. The second plug rod 322 and the second plug groove 32 are integrally cast. Alternatively, the second plug rod 322 can be screwed onto the second plug groove 32 for the same purpose of improving space utilization and facilitating storage and carrying.

[0036] It is conceivable that the number of the first plug-in rod 25, the plug-in hole 33, and the second plug-in rod 322 are the same, and their positions correspond to each other.

[0037] The diameter of the insertion hole 33 is the same as the outer diameter of the first insertion rod 25 and the second insertion rod 322, so that the first insertion slot 22 can be inserted into the second speaker 31 and the second insertion slot 32. The depth of the insertion hole 33 is at least twice the length of the first insertion rod 25, so that the first insertion rod 25, after being inserted into the insertion hole 33, occupies at most half the depth of the insertion hole 33, leaving sufficient space for the second insertion rod 322. The insertion hole 33 is covered with a top cover 34, which includes a top cover groove 341 and a plurality of third insertion rods 342 spaced apart in the top cover groove 341. The top cover 34 is inserted into the insertion hole 33 through the third insertion slots 342, sealing one end of the second speaker 31 to prevent foreign objects from falling into the insertion hole 33.

[0038] The length of the second connector rod 322 is slightly less than or equal to half the height of the second speaker 31. This allows the second connector rod 322 to be fully inserted into the connector hole 33, ensuring stability when assembled, and also allowing the side wall of the second speaker 31 to abut against the side walls of the first connector slot 22 and the second connector slot 32.

[0039] In use, the threaded end of the telescopic rod 21 is screwed and fixed to the threaded blind hole 13, and the height of the telescopic rod 21 is adjusted as needed. Then, the insertion hole 33 on the second speaker 31 is inserted into the first insertion rod 25. When multiple column speakers 30 are needed, the second insertion rod 322 on one end face of the second insertion slot 32 is inserted into the insertion hole 33, and the second insertion rod 322 on the other end face of the second insertion slot 32 is inserted into another second speaker 31. Finally, the top cover 34 is inserted into the other end of the second speaker 31 to seal it.

[0040] Compared with the prior art, the present invention provides a novel combined column speaker system. A first insertion slot 22 is provided at the end of the telescopic rod 21, and a first insertion rod 25 is provided at each of the four corners of the bottom of the first insertion slot 22. An insertion hole 33 is provided at each of the four corners of the second speaker 31. The second speaker 31 is fixed to the first insertion slot 22 by interlocking the insertion holes 33 with the first insertion rods 25. A second insertion slot 32 is also provided. Multiple second speakers 32 can be connected by interlocking the second insertion rods 322 provided on both ends of the second insertion slot 32 with the insertion holes 33. This system is easy to assemble and disassemble, requires no wiring, and allows for adjustment of the number of speakers in the combination as needed.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
