Description

Technical Field

[0001] The utility model relates to the field of speakers, in particular to a concave iron mesh speaker capable of strengthening sound waves. Background Art

[0002] A speaker, also known as a loudspeaker or horn, is a device that converts an audio signal into a sound signal and radiates it into space, and is a very crucial component in an audio system. A iron mesh is usually arranged on the front of the speaker. At present, the iron meshes on the front of speakers on the market are all flat or convex. Since the sound waves output through the flat and convex iron meshes are relatively dispersed, the output sound waves cannot be made more concentrated, and the volume level cannot be increased, which is not convenient for meeting different usage requirements of users.

[0003] Therefore, a concave iron mesh speaker capable of strengthening sound waves and capable of switching between concave and convex surfaces to meet different usage requirements of users has now been developed. Content of the Utility Model

[0004] In order to overcome the shortcomings that the iron meshes on the front of speakers on the market are all flat or convex, the output sound waves cannot be made more concentrated, the volume level cannot be increased, and it is not convenient for meeting different usage requirements of users, the utility model provides a concave iron mesh speaker capable of strengthening sound waves and capable of switching between concave and convex surfaces to meet different usage requirements of users.

[0005] The technical solution of the utility model is: a concave iron mesh speaker capable of strengthening sound waves, which includes a speaker main body, a concave mesh, clamping blocks, first springs and pins. The concave mesh is clamped on the upper side of the front part of the speaker main body. The upper side of the front part of the speaker main body is connected with clamping blocks through two left and right first springs. The clamping blocks are located on the upper side of the concave mesh. The lower sides of the left and right parts of the clamping blocks are both connected with pins, and the pins are in clamping fit with the concave mesh.

[0006] Furthermore, it also includes a handle, and the upper side of the middle part of the clamping block is connected with the handle.

[0007] Furthermore, the handle is provided with a soft pad.

[0008] Furthermore, it also includes shock absorbers, and the lower sides of the left and right parts of the speaker main body are both connected with shock absorbers.

[0009] Furthermore, it also includes a connecting frame, wheels and second springs. The rear side of the lower part of the speaker main body is connected with the connecting frame. The lower sides of the left and right parts of the connecting frame are both connected with wheels through damping sliding connections, and second springs are connected between the wheels and the connecting frame.

[0010] Furthermore, it also includes a pull handle, and the pull handle is connected with the connecting frame through a damping sliding connection.

[0011] The beneficial effects are as follows: 1. By pulling the clamping block upward, the first spring is stretched, causing the bolt to disengage from the concave mesh. Then, the concave mesh is flipped and repositioned on the speaker body. After releasing the handle, the first spring rebounds, causing the clamping block to move downward and reset, and the bolt to engage with the concave mesh again, converting the concave mesh into a convex surface, achieving the effect of being able to switch between concave and convex surfaces to meet different usage requirements of users.

[0012] 2. By pulling out the handle upward and then tilting the speaker body backward, the shock absorber is disengaged from the ground. Subsequently, the speaker body is moved through the handle and the wheels, achieving the effect of facilitating the movement of the speaker body.

[0013] 3. When the ground is uneven, the wheels move relative to the connecting frame, and through the action of the second spring, the vibration of the speaker body is reduced, preventing the speaker body from being damaged due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following specifically introduces the present invention in combination with the accompanying drawings and specific embodiments.

[0019] A concave iron mesh speaker that can strengthen sound waves, as Figures 1 - 3As shown in the figure, it includes a speaker main body 1, a concave-shaped net 2, clamping blocks 3, a handle 4, a first spring 5, a bolt 6, a shock absorber 7, a connecting frame 8, wheels 9, a second spring 10 and a pull handle 11. The upper side of the front part of the speaker main body 1 is clamped with the concave-shaped net 2. The upper side of the front part of the speaker main body 1 is connected with the clamping blocks 3 through two first springs 5 on the left and right. The clamping blocks 3 are located above the concave-shaped net 2. The upper side of the middle part of the clamping blocks 3 is connected with the handle 4. The handle 4 is provided with a soft pad for easy pulling. The lower sides of the left and right parts of the clamping blocks 3 are both connected with bolts 6. The bolts 6 are all in clamping fit with the concave-shaped net 2. The lower sides of the left and right parts of the speaker main body 1 are both connected with shock absorbers 7. The rear side of the lower part of the speaker main body 1 is connected with a connecting frame 8. The lower sides of the left and right parts of the connecting frame 8 are both connected with wheels 9 through a damping sliding connection. Second springs 10 are connected between the wheels 9 and the connecting frame 8. A pull handle 11 is connected to the connecting frame 8 through a damping sliding connection.

[0020] When using the present utility model, first place the speaker main body 1 in the use area. The shock absorber 7 contacts the ground to support the speaker main body 1, which can reduce the vibration generated when the speaker main body 1 is in use. When the speaker main body 1 plays audio, the sound is output from the concave-shaped net 2. The concave-shaped net 2 can make the sound waves output by the speaker more concentrated, strengthen the tightness of the waveform, and improve the volume level. When it is not necessary to improve the volume level, the clamping blocks 3 can be pulled upward by the handle 4. The first spring 5 is stretched, so that the bolts 6 are disengaged from the concave-shaped net 2. Then the concave-shaped net 2 is flipped and re-placed on the speaker main body 1. Then the handle 4 is released, and the first spring 5 rebounds, causing the clamping blocks 3 to move downward to reset, so that the bolts 6 are re-engaged with the concave-shaped net 2, making the concave-shaped net 2 converted into a convex surface, thus playing a role of being able to switch between the concave surface type and the convex surface type to meet different usage requirements of users. When it is necessary to move the speaker main body 1, the pull handle 11 can be pulled upward, and then the speaker main body 1 is tilted backward, so that the shock absorber 7 is disengaged from the ground. Then the speaker main body 1 is moved through the pull handle 11 and the wheels 9, so that it is convenient to move the speaker main body 1. When the ground is uneven, the wheels 9 move relative to the connecting frame 8. Through the action of the second spring 10, the vibration of the speaker main body 1 is reduced, and the speaker main body 1 is prevented from being damaged by vibration.

[0021] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
