Description

Technical Field

[0001] The utility model relates to the field of sound boxes, and in particular to a tower sound box connection structure with height adjustable characteristics. Background Art

[0002] In the field of speakers, tower speakers (also known as bass reflex speakers) are one of the more popular speakers launched in recent years. They physically separate the low-frequency area from the mid- and high-frequency areas, and structurally use an overall cabinet to divide the body into two or three sections. The low-frequency area is set at the bottom (or middle), and the mid- and high-frequency areas are set in the middle and upper sections. In terms of listening experience, the speaker has a strong degree of separation, less sound coloration in each frequency band, and stronger sound details and clarity.

[0003] However, the production of such tower speakers is relatively complicated, as they use a large box to install three units of different frequency bands and a main control, which cannot be separated or adjusted in height. In addition, such an integrated structure is not flexible in terms of packaging and transportation.

[0004] In view of this, the technical solution proposes a tower speaker connection structure with adjustable height. It adopts a detachable and adjustable tower structure, with a low-frequency zone at the bottom and a detachable or additional connection component at the top. The mid-high frequency zone can be set at an ideal height at the top through the connection component. The external structure of the mid-high frequency zone is also simplified, making the entire speaker smaller and easier to transport and place. Utility Model Content

[0030] as follows:

[0031] Please see attached Figure 1-9 ,

[0032] The main structure includes a first speaker group 1 and a second speaker group 3 located above the first speaker group 1. The first speaker group 1 and the second speaker group 3 are connected by a connecting component 2, and the connecting component 2 and the first speaker group 1 and the second speaker group 3 are all detachably connected. The first speaker group 1 includes a first box body 10 and a first sound-speaking area 11 arranged on one side of the first box body 10. A connecting position 2112 is provided at the top of the first box body 10. The connecting component 2 includes a connecting column 20 and a docking position arranged at the top of the connecting column 20. The second speaker group 3 includes a second box body 30 and a second sound-speaking area 31 arranged on one side of the second box body 30. The connecting column 20 and the bottom of the second box body 30 are both provided with connecting heads 22. The connecting component 2 is a stacking structure that can be added head to tail.

[0033] Here’s how it works:

[0034] The difference from the existing tower (stacked) structure speakers is that this solution uses an intermediate component (connection component 2) to connect the speakers at both ends. This connection method can minimize the degree of sound coloration (mutual interference between low frequency and mid-high frequency). The connection components 2 can be stacked one by one, and the user can increase the number of connection components 2 according to actual needs such as the size of the space. When connecting, first place the first speaker group 1, with the connection position 2112 of the first box body 10 facing up, and then insert the end of the connecting column 20 with the connecting head 22 into the connecting position 2112, and finally dock the connecting head 22 of the second box body 30 with the docking position on the top of the lower connecting column 20 to complete the installation.

[0035] A preferred embodiment of the present invention is that the connector 22 is an inverted trapezoidal structure with the bottoms on both sides being inwardly contracted, and the inverted trapezoidal structure forms an interference fit connection with the docking position.

[0036] The inverted trapezoidal connector 22 can avoid the vibration caused by the straight-tube structure fitting against the inner wall, thereby reducing the generation of noise.

[0037] A preferred embodiment of the present invention: the first speaker group 1 is a main control speaker structure with a control unit on the back. The first speaker area 11 is a low-frequency speaker. The second speaker area 31 is a medium-high frequency speaker.

[0038] The first speaker group 1 is a main bass speaker with a control unit on the back, while the second speaker area 31 is a mid-high frequency speaker. Placing the mid-high frequency speaker on the top is conducive to the full diffusion of the high frequency and further separation from the low frequency.

[0039] A preferred embodiment of the present invention: the connecting head 22, the connecting column 20 and the second box body 30 are all ultrasonically welded connection structures.

[0040] The connector 22 is connected to the bottom of the connecting column 20 by ultrasonic welding to form an integrated structure, without using screws or punching holes, thereby improving the structural strength.

[0041] A preferred embodiment of the present invention is that the connecting column 20 is a column structure with a cavity in the middle. The second speaker group 3 can adopt a contact point (magnetic contact point) contact method or a wiring method. If the wiring method is adopted, it passes through the hollow part of the connecting column 20 to connect with the first speaker group 1.

[0042] The above description is only a preferred embodiment of the technical solution of the utility model, and does not limit the patent scope of the technical solution of the utility model. All equivalent structural changes made by using the contents of the technical solution description and drawings of the utility model under the conception of the technical solution of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the utility model.
