Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to an aluminum cone tweeter. 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 energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, producing sound. As people's living standards improve, their demands for the sound quality of audio-visual systems are also increasing, imposing limitations on the size and thickness of tweeters and placing greater emphasis on their sound quality.

[0003] Patent document CN220755038U discloses a tweeter with a phase plug, including a tweeter body having a sound-producing area; a phase plug body located in the sound-producing area is mounted on the tweeter body; the phase plug body includes a conical portion and a connecting portion located at the lower end of the conical portion, the conical portion having an outwardly protruding first curved surface and a second curved surface, the height of the second curved surface being greater than the height of the first curved surface, and the curvature of the first curved surface being greater than the curvature of the second curved surface; the curvatures of the first curved surface and the second curved surface being the same at the connection point; by mounting the phase plug body in the sound-producing area of ​​the tweeter body, and providing the first curved surface and the second curved surface on the conical portion of the phase plug body, the emitted sound can be converged by the first curved surface and the second curved surface before being emitted outward, thereby improving the resolution of the emitted sound.

[0004] In the above solution, although the tweeter is equipped with a phase plug to enhance the sound quality, the high-frequency sound is easily attenuated rapidly with increasing distance due to the direct vibration of the diaphragm. The propagation range is limited, which may result in the sound not being full enough or lacking brightness. It is also easily limited by the quality of the diaphragm, with the high-frequency extension usually only reaching 15kHz, and the high-frequency sensitivity is significantly reduced. Therefore, it is necessary to provide an aluminum cone tweeter to solve the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Example 1:

[0026] In this embodiment, as Figure 1-4As shown, this utility model proposes an aluminum cone tweeter, including a speaker body 1. The speaker body is provided with a T-iron 2, a magnet 3, a washer 4, a positioning ring 5, and a frame 6 from bottom to top. The positioning ring is equipped with a vibration assembly, which includes a support plate 7, a buffer pad 8, a diaphragm 9, a voice coil 10, and a terminal block 11. The support plate has a circular hole 701 in the middle. The bottom surface of the buffer pad is connected to the top surface of the support plate, and the bottom surface of the diaphragm is connected to the top surface of the buffer pad. The top of the voice coil passes through the circular hole and is connected to the diaphragm. The support plate has terminal blocks at both ends, and the terminal blocks are connected to the voice coil through lead wires 12. The frame is horn-shaped. The sound generated by the vibration of the diaphragm is amplified by the frame, which can widen the effective propagation range of high frequencies, making the high-frequency sound more prominent and bright. The top center of the frame has a phase cone 13, which can reduce sound wave interference, enhance high-frequency directivity, and maintain high loudness and good clarity at a greater distance.

[0027] In this example, the T-iron is made of pure iron or low-carbon steel, the magnet is made of neodymium iron boron, the washer is made of nickel-iron alloy, the positioning ring and support plate are made of plastic, and the frame is made of aluminum. The aluminum cone has good rigidity, which can prevent the sound from deforming during propagation due to its soft material, thus improving sound stability and reducing resonance.

[0028] In this example, the T-iron, magnet, washer, and positioning ring are all bonded together with adhesive. The positioning ring has a groove in the middle, in which the vibration component is embedded. The top of the positioning ring has a through hole, and the connecting bolts pass through the connecting hole and the through hole in sequence to connect the frame to the positioning ring.

[0029] In this embodiment, the support plate is further configured to include a circular body 702, a left ear plate 703 and a right ear plate 704, with the two ends of the circular body connected to the left ear plate and the right ear plate respectively, and the left ear plate and the right ear plate being symmetrically arranged.

[0030] In this embodiment, the buffer pad is further configured to be circular in shape, made of EVA cotton, with the width of the buffer pad matching the width of the main body of the circular ring, and the bottom surface of the buffer pad being attached to the top surface of the main body of the circular ring.

[0031] In this embodiment, the wiring terminals are further configured to be a pair, with the wiring terminals respectively located at the ends of the left and right ear plates.

[0032] In this embodiment, the diaphragm is further configured such that the middle part of the diaphragm is corrugated and the outer edge of the bottom surface of the diaphragm is attached to the top surface of the buffer pad.

[0033] In this example, an aluminum sheet is used for the diaphragm. When driven by the voice coil, the aluminum diaphragm can move more accurately according to the changes in the audio signal. It is less prone to irregular deformation due to its soft material, which helps to improve the accuracy of sound reproduction. Due to its rigidity and relatively light weight, the diaphragm can respond quickly to changes in the audio signal and can quickly change its vibration state during rapid vibration. At the same time, aluminum has good heat dissipation properties, which can help dissipate heat quickly. To a certain extent, it can protect the internal components of the speaker and reduce the risk of performance degradation or damage to components such as the voice coil due to overheating. This ensures that the speaker can work stably for a long time and maintain stable sound output.

[0034] Example 2:

[0035] In this embodiment, as Figure 1-2 As shown, based on Embodiment 1, the top of the basin frame is provided with an annular groove 14, the inner circumferential of the annular groove is provided with an auxiliary hole 15, and the annular groove is engaged with a ring 16.

[0036] In this embodiment, the frame is further configured with mounting holes 17 around its perimeter, and mounting bolts pass through the mounting holes to connect with the mounting components, thereby preventing the speaker body from shifting during use.

[0037] In this embodiment, the basin frame is further configured such that a connecting hole 18 is provided at the bottom of the basin frame, and a connecting bolt passes through the connecting hole to connect the basin frame to the positioning ring.

[0038] In this example, due to the small size of the speaker body and frame, it is not convenient to tighten the connecting bolts and connecting holes from the side when installing the frame and the positioning ring. Therefore, a ring groove and an auxiliary hole are made on the top of the frame. The auxiliary hole and the connecting hole are aligned on the axis. A screwdriver is passed through the auxiliary hole to tighten the connecting bolts and the connecting hole. The ring is then snapped into the ring groove to decorate the auxiliary hole and make it more aesthetically pleasing.

[0039] The sound-producing principle of this aluminum cone tweeter is that the sound generated by the vibration of the diaphragm is amplified by the basket, which widens the effective propagation range of high frequencies, making the high-frequency sound more prominent and bright. Then, it is transmitted through the phase cone to reduce sound wave interference and enhance the high-frequency directivity, so as to maintain high loudness and good clarity at a long distance.
