Description

Technical Field

[0001] This utility model relates to the field of loudspeaker horn technology, and in particular to a loudspeaker horn. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most crucial for sound effects. There are many types of loudspeakers, and their prices vary greatly. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, producing sound. The main function of assembling a horn in a loudspeaker is to improve its radiation efficiency and control the directivity of the sound.

[0003] For example, our company's previously filed Chinese patent application, CN220067683U, discloses an ultra-thin woofer, which includes a frame assembly, a vibration assembly, and a magnetic circuit assembly. Both the vibration assembly and the magnetic circuit assembly are located inside the frame assembly. The frame assembly includes a frame body and a support frame. The frame body has an opening at its center, and the top of the vibration assembly is located within this opening. The lower end of the vibration assembly is fitted onto the magnetic circuit assembly. The magnetic circuit assembly is fixedly connected to the frame body via a first connecting mechanism. The support frame is located below the frame body, and its top end is connected to the frame body via a second connecting mechanism, forming an installation space. The bottom end of the support frame is fixedly connected to the magnetic circuit assembly via a third connecting mechanism. This utility model features a frame assembly, including a frame body and a support frame, which form an installation space. The magnetic circuit assembly and the vibration assembly are disposed within this installation space. Compared to existing loudspeakers that place the magnetic circuit assembly outside the frame, this design makes the loudspeaker structure more compact and smaller in size.

[0004] In the above solutions, the loudspeaker has poor acoustic performance due to the lack of a loudspeaker horn, a short sound propagation distance, and an inability to accurately reproduce sound signals, making it prone to distortion. Furthermore, the sound cannot propagate in a directional manner, failing to meet current requirements. As for the loudspeaker horn with an improved structure disclosed in patent document CN207117931U, its tube structure is not stable enough, making it prone to vibration and affecting sound quality. In addition, the stability of the base connection also affects sound quality. Therefore, it is necessary to provide a loudspeaker horn to address the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a horn for loudspeakers.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A loudspeaker horn includes a horn body, which comprises a base, a tube body, and a top plate. The base, tube body, and top plate are integrally formed. A sound input port is provided in the center of the base. Positioning holes one and two are symmetrically provided on the edge of the base. Positioning bolt one passes through positioning hole one and is connected to the loudspeaker frame. Positioning bolt two passes through positioning hole two and is connected to the loudspeaker frame. The lower section of the tube body is a conical section, the bottom of which is connected to the top surface of the base. The upper section of the tube body is a horn section, the bottom of which is connected to the top of the conical section. The top of the horn section is connected to the bottom of the top plate. Reinforcing ribs are provided around the tube body to improve the structural strength of the tube body and reduce tube body vibration. A sound output port is provided in the center of the top plate. Mounting holes are arrayed on the outer edge of the top plate. Mounting bolts pass through the mounting holes and are connected to mounting components to prevent the horn body from shifting during use.

[0008] The present invention is further provided that the bottom inner ring of the base is provided with an annular groove, which can prevent the bottom of the base from contacting the outer edge of the speaker diaphragm, thereby affecting the speaker's sound production.

[0009] The present invention is further provided that the outer ring of the base has a hollow groove, which can reduce the weight of the base and facilitate installation and adjustment.

[0010] The present invention is further configured such that positioning hole one and positioning hole two have the same shape and are rounded rectangles, which facilitates the insertion of positioning bolt one and positioning bolt two, reduces the difficulty of positioning, and facilitates adjustment.

[0011] The present invention is further configured such that the cross-section of the conical section gradually decreases from bottom to top, and the cross-section of the horn section gradually increases from bottom to top.

[0012] The present invention is further provided with a triangular hole between the speaker output port and the mounting hole. The triangular hole can reduce the weight of the top plate and save materials.

[0013] The present invention is further configured such that the top plate is rectangular and the four corners of the top plate are rounded, which can avoid the problem of scratching or cutting hands caused by right angles.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The present invention has reinforcing ribs on the outer circumference of the tube body. The reinforcing ribs can improve the tube body's resistance to deformation, improve stability, reduce the vibration amplitude of the tube body during sound production, and facilitate manufacturing while avoiding stress concentration.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] Example 1:

[0024] In this embodiment, as Figure 1-3As shown, this utility model proposes a loudspeaker horn, including a horn body 1, which includes a base 2, a tube body 3, and a top plate 4. The base, tube body, and top plate are integrally formed. The base has a sound input port 21 in the middle, and positioning holes 22 and 23 are symmetrically provided on the edge of the base. Positioning bolt 1 passes through positioning hole 1 and is connected to the loudspeaker frame, and positioning bolt 2 passes through positioning hole 2 and is connected to the loudspeaker frame. The lower section of the tube body is a conical section 31, and the bottom of the conical section is connected to the top surface of the base. The upper section of the tube body is a horn section 32, and the bottom of the horn section is connected to the top of the conical section. The top of the horn section is connected to the bottom of the top plate. The tube body is provided with reinforcing ribs 5 around its circumference. The reinforcing ribs can improve the tube body's resistance to deformation, improve stability, reduce the vibration amplitude of the tube body during sound production, and facilitate manufacturing while avoiding stress concentration. The top plate has a sound output port 41 in the middle, and mounting holes 42 are arrayed on the outer edge of the top plate. Mounting bolts pass through the mounting holes and are connected to the mounting parts to prevent the horn body from shifting during use.

[0025] In this example, the loudspeaker is an existing product and technology, and will not be described in detail here. It is not shown in the figure. The size of the loudspeaker frame matches the size of the base. Also, positioning bolt one, positioning bolt two and mounting bolts are not shown in the figure.

[0026] In this embodiment, the base is further configured to have an annular groove 24 on the inner ring of the bottom. The annular groove can prevent the bottom of the base from contacting the outer edge of the speaker diaphragm, thereby affecting the speaker's sound output.

[0027] In this embodiment, the base is further configured with a slot 25 on the outer ring, and multiple slots are symmetrically arranged. The slots can reduce the weight of the base, facilitate installation and debugging, and at the same time reduce structural deformation caused by stress concentration when the speaker is working, thereby enhancing the stability of the structure.

[0028] In this embodiment, the positioning hole one and positioning hole two are of the same shape and are rounded rectangles, which makes it easy for positioning bolt one and positioning bolt two to be inserted, reducing the difficulty of positioning, facilitating adjustment, and making it suitable for various speakers.

[0029] In this embodiment, the cone section gradually decreases in cross-section from bottom to top, while the horn section gradually increases in cross-section from bottom to top, so that the sound is transmitted directionally through the speaker input port, the tube body, and the speaker output port, allowing the sound to travel further and more clearly.

[0030] In this embodiment, a triangular hole 43 is provided between the speaker output port and the mounting hole. The triangular hole can reduce the weight of the top plate and save materials.

[0031] Example 2:

[0032] In this embodiment, as Figure 1-3As shown, based on Embodiment 1, the top plate is rectangular, and the four corners of the top plate are rounded. The rounded corners can avoid the problem of scratching or cutting hands caused by right angles, thereby improving the safety of the product and the user experience.

[0033] In this embodiment, the top plate is further configured with a marking area 44 in the middle of its edge. The marking area is rectangular and has a pair of marking areas.

[0034] In this example, the label area can also be set to one. In this case, the label area can slightly increase its obstruction of the speaker output port, while the opposite side of the label area does not obstruct the speaker output port.
