Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker technology, and in particular to a small tweeter horn loudspeaker. Background Technology
[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. As people's living standards improve, their demands for the sound effects of audio-visual systems are also increasing. This not only limits the size and thickness of tweeters but also places great emphasis on their sound quality.
[0003] Patent document CN218850971U discloses a high-propagation horn loudspeaker with a phase plug integrally molded within the front housing's sound chamber. This eliminates the need for connecting and fixing components, reducing cumbersome installation steps, lowering production costs, and saving assembly time. Furthermore, when the loudspeaker generates sound waves, the phase plug within the sound chamber effectively corrects the sound wave reflection angle, thus widening the sound wave's propagation angle. The sound waves then propagate outwards through the mesh cover within the sound chamber. Due to the arc-shaped dome design at the top of the mesh cover, sound diffraction is effectively reduced upon contact with the dome, allowing the sound waves to propagate effectively over a wider space without affecting sound quality.
[0004] In the above solution, the loudspeaker improves its radiation efficiency and controls the directivity of the sound by adding a horn. However, the horn is connected to the speaker frame with bolts, and mismatch issues at the interface may lead to energy loss. If the added horn is not precisely calibrated, phase distortion or frequency response dips may occur near the crossover point. It is also prone to uneven directivity diffusion due to physical size limitations. The output end of the horn is not equipped with a positioning component, and the horn output end is prone to displacement. The loudspeaker has a housing and adjustment components, and its size is too large to meet the needs of a compact installation space. Furthermore, some small loudspeakers do not consider heat dissipation issues. Therefore, it is necessary to provide a small tweeter horn loudspeaker to solve the shortcomings of the existing technology. Utility Model Content

Detailed Implementation
[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. 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.
[0030] Example 1:
[0031] In this embodiment, as Figure 1-8 As shown, this utility model proposes a small high-frequency horn loudspeaker, including a base 1, with mounting seats 11 and fins 12 arranged in a circumferential array on the base, and a housing 2 on the top of the base. The housing is integrally formed and includes, from bottom to top, a mounting part 21, a neck 22, a tube body 23, and a positioning part 24. Both the base and the mounting part have mounting spaces inside. The top surface of the mounting part has mounting holes 211 arranged in a circumferential array. Connecting bolts pass through the mounting holes and mounting seats to connect the mounting part to the base. The side of the mounting part has a notch, and a support plate 3 is provided inside the mounting part. The end of the support plate passes through the notch and faces outward from the mounting part. The positioning part has a positioning hole 241, and a positioning bolt passes through the positioning hole to connect the positioning part to the mounting part, preventing the housing from shifting during use.
[0032] In this example, the base contains a T-shaped iron, a magnet, and a washer. This structural technology is existing technology and will not be described in detail here.
[0033] In this embodiment, it is further configured that there are three mounting bases and three mounting holes, with each mounting base and mounting hole corresponding to the other. The distance between adjacent mounting bases and mounting holes is 120 degrees. The number of mounting bases and mounting holes can also be increased to four, in which case the distance between adjacent mounting bases and mounting holes is 90 degrees.
[0034] In this example, there are 9 fins between adjacent mounting bases, and the spacing between adjacent fins is 12 degrees. The fins can conduct heat away from the speaker and reduce the weight of the base.
[0035] In this embodiment, the neck is further configured to be cylindrical, with a neck diameter smaller than the mounting portion diameter and a neck diameter larger than the bottom diameter of the tube body, thereby strengthening the structural strength of the shell.
[0036] In this example, the tube body is directly connected to the mounting part, and the connection is relatively fragile and easily damaged. Therefore, a neck is added. The thickened neck can strengthen the structural strength of the shell, while providing transition space for sound transmission and installation space for the phase cone.
[0037] In this embodiment, the tube body is further configured to be trumpet-shaped, with a circular bottom cross-section and an elliptical top cross-section, and the short radius of the top of the tube body is greater than the radius of the bottom of the tube body.
[0038] In this example, due to the integrated design of the housing, the shape and curvature of the tube can be adjusted according to the sound emission test of the internal structure of the housing, so as to precisely control the horizontal and vertical diffusion angles, reduce environmental reflection interference, and achieve good conduction.
[0039] In this embodiment, the positioning part is further configured to be rectangular, with a flange 242 on the edge of the positioning part, and a reinforcing part 243 between the flange and the positioning hole. The reinforcing part can prevent damage to the positioning hole when the positioning bolt is installed, and strengthen the structural strength of the positioning part.
[0040] In this embodiment, the support plate is further configured to be in the shape of a ring, and an extension portion 31 is symmetrically provided at one end of the support plate, and the extension portion is provided with a wiring terminal 4.
[0041] In this example, the terminal blocks are positioned on the same side to avoid tangling of the connecting wires, which helps to reduce the required size of the speaker installation without affecting the speaker's function.
[0042] In this embodiment, the support plate is further configured such that a buffer pad 5 is provided on the top surface of the support plate, a diaphragm 6 is provided on the top surface of the buffer pad, the top of the voice coil 7 passes through the support plate and is connected to the diaphragm, and the voice coil is connected to the terminal block through a lead wire 8.
[0043] In this example, the buffer pad is annular, with an inner diameter larger than the support plate and an outer diameter smaller than the support plate, and the diaphragm is corrugated.
[0044] In this embodiment, a phase cone 9 is provided at the center of the neck, and the phase cone coincides with the axis of the base and the outer shell.
