Description

Technical Field

[0001] The present application relates to the technical field of sound boxes, and in particular to a sound box with low noise and strong sound layering. Background Art

[0002] A speaker is a device that converts electrical signals into sound. It is used to amplify and play audio signals. It is usually composed of one or more drive units (such as speakers). They convert electrical signals into sound and transmit the sound into the surrounding air through the box structure.

[0003] In the prior art, with the development and progress of speaker technology, the internal structure of the speaker has become more and more complex, and the appearance has been designed to be more and more beautiful. Some miniaturized speakers are equipped with two symmetrically arranged tweeters to increase the three-dimensional sense of sound and ensure the stability of the treble, but the symmetrically arranged tweeters make the sound lack a sense of layering and the sound effect is relatively single; at the same time, miniaturized speakers are usually equipped with handles and other structures for users to carry easily, but the handle structure usually damages the outer wall of the box, and the speaker will vibrate when working, causing the outer wall where the handle is installed to emit vibration sound, thereby interfering with the sound emitted by the speaker and distorting the sound emitted by the speaker.

[0004] Therefore, the inventor is necessary to design a new low-noise and high-level sound box to overcome the above problems. Summary of the invention

[0005] The main purpose of the present application is to provide a speaker with low noise and strong sound layering, so as to solve the problems of lack of layering of high pitch and vibration at the handle in the related art.

[0006] In order to achieve the above-mentioned object, the present application provides a low-noise speaker with a strong sense of sound hierarchy, comprising a speaker box, a mesh assembly, a top shell, and a bottom shell, wherein the speaker box is fixedly connected between the top shell and the bottom shell, the mesh assembly is wrapped around the outside of the speaker box and fixedly connected between the top shell and the bottom shell, and two tweeters are fixedly installed on the speaker box, and the two tweeters are asymmetrically installed;

[0007] It also includes a handle, which is rotatably mounted on the outer wall of the mesh assembly through a bolt assembly, and a shock-absorbing member is also arranged between the bolt assembly and the speaker box body.

[0008] Preferably, two installation cavities are fixedly provided at the upper end of the speaker box, and the two tweeters are fixedly installed in the installation cavities, and the two installation cavities are asymmetrically arranged.

[0009] Preferably, the angle between the central axis of one of the installation cavities and the central axis of the mesh assembly is 30°, and the angle between the central axis of the other installation cavity and the central axis of the mesh assembly is 15°.

[0010] Preferably, the bolt assembly includes a bolt body and a nut body, and the bolt body passes through the handle and is fixedly connected to the mesh assembly through the nut body.

[0011] Preferably, an inner concave cavity is provided on the speaker box body, and the nut body is located between the inner concave cavity and the mesh assembly.

[0012] Preferably, the shock absorbing member comprises an EVA sleeve, and the EVA sleeve is sleeved on the outer wall of the nut body.

[0013] Preferably, a woofer is fixedly disposed at the lower end of the speaker box.

[0014] Preferably, the bolt assemblies are symmetrically arranged in two groups, and the two ends of the handle are rotatably mounted on the outer wall of the mesh assembly through the two handle assemblies.

[0015] Preferably, the mesh assembly is clamped between the top shell and the bottom shell.

[0016] The utility model provides a low-noise speaker with a strong sense of sound layering. Compared with the prior art, the utility model has the following beneficial effects:

[0017] By installing the two tweeters on the speaker cabinet asymmetrically, the sounds emitted by the two tweeters have phase differences. At the same time, the sounds emitted overlap at different positions through the oscillation of objects in the space, producing complex and changeable acoustic effects, thereby increasing the layering and three-dimensional sense of the sound. At the same time, an EVA cushion cover is put on the outside of the nut so that the speaker cabinet hits the EVA cushion cover when it vibrates, thereby greatly reducing the vibration sound at the handle installation point.

[0033] like Figures 1 to 7As shown, a low-noise speaker with a strong sense of sound hierarchy comprises a speaker box 1, a mesh assembly 2, a top shell 3, and a bottom shell 4, wherein the speaker box 1 is fixedly connected between the top shell 3 and the bottom shell 4, the mesh assembly 2 is wrapped around the outside of the speaker box 1 and fixedly connected between the top shell 3 and the bottom shell 4, two tweeters 5 are fixedly installed on the speaker box 1, and the two tweeters 5 are installed asymmetrically; it also comprises a handle 6, which is rotatably installed on the outer wall of the mesh assembly 2 by a bolt assembly, and a shock-absorbing member is also arranged between the bolt assembly and the speaker box 1; when working, components such as chip boards are pre-installed on the bottom shell 4, components such as control panels are pre-installed on the top shell 3, the diameter of the bottom shell 4 is larger than the diameter of the top shell 3, the mesh assembly 2 is truncated cone-shaped, and its outer peripheral surface has velvet The cloth is not only beautiful but also can make the sound more balanced. During installation, the speaker box 1 is first fixedly installed with the bottom shell 4, and then the cloth net component 2 equipped with the handle 6 is wrapped around the outside of the speaker box 1, and then the top shell 3 is fixedly installed with the speaker box 1, so that the assembly of the entire speaker is realized. Here, the connection method between the speaker box 1 and the top shell 3 and the bottom shell 4 can be bolt connection, snap connection, etc., and the two tweeters 5 on the speaker box 1 are installed asymmetrically, so that the sounds emitted by the two tweeters 5 have phase differences, and the sounds emitted overlap at different positions through the oscillation of objects in the space, thereby producing complex and changeable acoustic effects, thereby increasing the layering and three-dimensional sense of the sound; at the same time, the EVA cushion sleeve 11 is put on the outside of the nut, so that the speaker box 1 hits the EVA cushion sleeve 11 when vibrating, thereby greatly reducing the vibration sound at the installation point of the handle 6.

[0034] Two mounting cavities 7 are fixedly provided at the upper end of the speaker cabinet 1, and the two tweeters 5 are fixedly installed in the mounting cavities 7, and the two mounting cavities 7 are asymmetrically arranged; the angle between the central axis of one of the mounting cavities 7 and the central axis of the mesh assembly 2 is 30°, and the angle between the central axis of the other mounting cavity 7 and the central axis of the mesh assembly 2 is 15°; when working, the mounting cavity 7 is an integrally formed depression of the speaker cabinet 1, and the tweeter 5 is fixedly installed in the mounting cavity 7. Generally speaking, an asymmetrical arrangement will produce phase differences. If the phase difference is too small, the sense of hierarchy will be relatively weak. If the phase angle is too large, the sound may appear messy and the listening experience will deteriorate. In actual use, the design with an angle of 30° on one side and 15 degrees on the other side makes the overall listening experience of the sound relatively good.

[0035] The bolt assembly includes a bolt body 8 and a nut body 9. The bolt body 8 penetrates the handle 6 and is fixedly connected to the mesh assembly 2 through the nut body 9. An inner concave cavity 10 is provided on the speaker box 1, and the nut body 9 is located between the inner concave cavity 10 and the mesh assembly 2. During operation, before installing the mesh assembly 2, the nut body 9 is first placed in the inner concave cavity 10, and then the handle 6, the bolt body 8 and the bolt holes on the mesh assembly 2 are installed. The bolt body 8 and the nut body 9 are tightened to realize the installation of the handle 6. The handle 6 here can be fixedly connected to the bolt body 8 or rotatably connected, and can be set according to actual needs.

[0036] The shock absorbing member comprises an EVA cushion sleeve 11, and the EVA cushion sleeve 11 is sleeved on the outer wall of the nut body 9; when working, the EVA cushion sleeve 11 has a good shock absorbing effect, a strong deformability, and a low cost.

[0037] A woofer 12 is also fixedly disposed at the lower end of the sound box body 1; when in operation, the woofer 12 cooperates with the tweeter 5 to produce rich sound effects.

[0038] The bolt assemblies are symmetrically arranged in two groups, and the two ends of the handle 6 are rotatably mounted on the outer wall of the mesh assembly 2 through the two handle 6 assemblies.

[0039] The mesh assembly 2 is clamped between the top shell 3 and the bottom shell 4. When working, a clamping slot can be opened on the top shell 3 and the bottom shell 4, and the mesh assembly 2 can be clamped between the clamping slots of the two to achieve fixed installation, which simplifies the installation structure and is more beautiful.
