Description

Technical Field

[0001] The utility model relates to the field of sound boxes, and in particular to an inverted tower sound box with sufficient noise reduction characteristics. Background Art

[0002] From the perspective of speaker structure, it can be divided into sealed speakers, bass reflex speakers, labyrinth speakers, sonic tube speakers and multi-cavity resonance speakers, etc. For bass reflex speakers, it is a relatively new speaker structure, thanks to the specially designed acoustic cavity, it has excellent low-frequency performance and good sound field characteristics.

[0003] Most bass reflex speakers on the market currently use a conventional sound column (or rectangular box) structure, which creates a unique acoustic effect with the desktop (or ground) by setting the low-frequency sound source at the bottom. However, after long-term use, this type of rectangular box structure may have a gap between the base and the speaker body. This is because the base is slightly deformed due to the weight of the speaker body, which will produce noise over time. Due to the limitations of this type of "strong shock absorption", the low frequency that should be there cannot be fully released, affecting the listening experience. In addition, for scenes where there is no installation space at the bottom, this type of box-type speaker structure is inconvenient to install.

[0004] In view of this, this technical solution proposes an inverted tower speaker with sufficient noise reduction characteristics, which adopts a hoisting structure and can be installed with various hoisting parts. It uses a shock-absorbing cone assembly formed by stacking multiple cones to gradually reduce the over-release wave, but can maintain the frequency and enhance the listening experience. The overall structure is not complicated, and the product is easy to assemble and install. Utility Model Content

To this end, the main purpose of the utility model is to provide an inverted tower speaker with sufficient noise reduction characteristics, aiming to solve the problem that the inverted speaker in the prior art has poor noise reduction effect and does not have a hanging structure.

[0006] To achieve the above-mentioned purpose, the utility model provides an inverted tower speaker with sufficient noise reduction characteristics, including a speaker body, and a hanging piece arranged at the top of the cavity of the speaker body, and a noise-reducing shock-absorbing cone assembly is arranged at the bottom of the cavity.

[0007] The hanging part includes a top plate arranged at the top of the cavity, and hanging holes opened on the top plate, and positioning columns are arranged at each corner of the top plate.

[0008] The shock-absorbing frustum assembly includes a mounting seat arranged at the bottom of the cavity, and frustums that are conically sleeved from the outside to the inside of the mounting seat and downward in sequence, the bottom of each frustum is in contact with the mounting seat, the bottom of the frustum is provided with a cone head, and the bottom end of the cone head is provided with a cone tip.

[0024] as follows:

[0025] Please see attached Figure 1-4 ,

[0026] The main structure includes a speaker body 1, and a hanging part 2 arranged on the top of the cavity 10 of the speaker body 1, a noise-reducing shock-absorbing cone 31 assembly 3 is provided at the bottom of the cavity 10, the hanging part 2 includes a top plate 20 arranged at the top of the cavity 10, and hanging holes opened on the top plate 20, and positioning columns 21 are provided at each corner of the top plate 20. The shock-absorbing cone 31 assembly 3 includes a mounting seat 30 arranged at the bottom of the cavity 10, and each cone 31 is conically sleeved from the mounting seat 30 from the outside to the inside and downward in sequence, the bottom of each cone 31 is fitted with the mounting seat 30, the bottom of the cone 31 is provided with a cone head 32, and the bottom end of the cone head 32 is provided with a cone tip 33.

[0027] Here’s how it works:

[0028] During installation, first fix the top plate 20 to the external fixing parts (fixing structures such as beams, fixing frames or fixing rods), and then install one end of the cavity 10 of the speaker body 1 (which can be positioned and then fixed by the positioning column 21) to the top plate 20, which can be screwed or directly welded to form an integral structure. After the top fixing structure is installed, the mounting seat 30 is installed on the bottom of the speaker body 1, and then each cone 31 is sequentially sleeved from the inside to the outside (or from the outside to the inside) with the cone facing downward, and a cone head 32 is set at the bottom, and a cone tip 33 is set at the bottom of the cone head 32 (the cone tip 33 can be a replaceable and detachable structure, suitable for replacing the test sound field for various environments).

[0029] When the speaker body 1 generates low frequencies, the over-excited audio is transmitted from the cone 31 to the cone tip 33 and the vibration is reduced (or even disappears). Since the shock-absorbing cone 31 component 3 is not a completely wave-absorbing structure, it will not lose a lot of low frequencies. Therefore, it can restore the sound itself, weaken the over-excited low frequencies, and reduce noise.

[0030] The speaker body 1 with a hanging structure reduces the bottom space, and the bottom space is used to set the shock-absorbing mechanism, which is a shock-absorbing cone 31 assembly 3. By using a plurality of cones 31 to be connected, and the volume of the cone 31 is gradually reduced to the cone tip 33, the low-frequency vibration of the over-discharge is weakened. Another advantage of the hanging structure is that due to the influence of gravity, the speaker body 1 will not gradually cling to the external fixing parts, and the noise will not be increased after long-term use.

[0031] A preferred embodiment of the present invention: the sound box body 1 further comprises an absorbing column 11 arranged closely to each side of the cavity 10, and the absorbing column 11 is an embedded concave absorbing corrugated structure.

[0032] The function of the wave absorbing columns 11 is to reduce the distortion caused by the vibration waves in the cavity 10 colliding with the corners of the cavity 10 , and the wave absorbing columns 11 arranged at the corners of the cavity 10 can offset these collisions, making the sound waves inside the cavity 10 smooth and natural.

[0033] A preferred embodiment of the present invention: the mounting base 30 is welded to the bottom of the speaker body 1 .

[0034] A preferred embodiment of the present invention: the hanging member 2 further comprises a connecting rod 22 which is arranged in the cavity and whose two ends are respectively connected to the top plate 20 and the cone head 32 .

[0035] The connecting rod 22 can not only support the sound box body 1, but also be used to tighten the cones 31 so that the cones 31 are more closely attached.

[0036] A preferred embodiment of the present invention is as follows: washers 34 corresponding to the number of cones 31 are provided at the bottom of the speaker body 1 , and the washers 34 are arranged in concentric circles and are tightly attached to the bottom of each cone 31 .

[0037] The washer 34 is provided to help the cone 31 form a sealing structure and also has the function of reducing vibration caused by hard contact between the cone 31 and the box (or base).

[0038] A preferred embodiment of the present invention: the cone 31 and the cone head 32 are both stainless steel structures formed in one step.

[0039] Stainless steel has the characteristics of corrosion resistance, high hardness and strong acoustic conductivity. The stainless steel cone 31 and cone head 32 are provided so that it can be used for a long time without deformation.

[0040] A preferred embodiment of the present invention: the cone tip 33 is a detachable and replaceable structure, and the cone tip 33 is rotatably connected to the cone head 32 through a thread.

[0041] The cone tip 33 may be a replaceable and detachable structure, and is suitable for replacing the test sound field in various environments.

[0042] The above are only preferred embodiments of the technical solution of the utility model, and do 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.
