Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a surround pneumatic tweeter unit and loudspeaker. Background Technology

[0002] AMT (Air Motion Transformer) is a special tweeter technology. Its core lies in using a corrugated thin-film diaphragm to generate sound by rapidly compressing and stretching air under the influence of a magnetic field. The diaphragm of an AMT aerodynamic unit is typically made of lightweight, high-strength materials (such as polyimide film or aluminum foil), and its corrugated design increases the effective surface area of ​​the diaphragm. Conductive paths are embedded in the diaphragm; when energized in a magnetic field, an electromagnetic force is generated, propelling the diaphragm to move rapidly back and forth. Due to the compression of the diaphragm, air is expelled at a high speed, resulting in higher efficiency and faster response.

[0003] Despite the superior performance of AMT tweeters, they still face some limitations and challenges in practical applications. AMT tweeters have a narrower sound wave dispersion and significant directionality in the high-frequency range, which may degrade the listening experience for listeners not positioned directly in front of them. Furthermore, due to their lighter diaphragm and smaller amplitude of movement, AMT units are better suited for high-frequency response and contribute less to low frequencies. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a surround pneumatic tweeter and loudspeaker to solve the problems in the background art.

[0005] A surround-type pneumatic tweeter includes a top frame, a base, a diaphragm, and a magnet assembly. The top frame and the base are arranged vertically opposite each other. The magnet assembly and the diaphragm are both arranged in a ring shape. The upper and lower ends of the magnet assembly and the diaphragm are both located between the top frame and the base, and the diaphragm is located on the outside of the magnet assembly. In addition, the diaphragm is pleated.

[0006] Furthermore, an inner ring and an outer ring are provided on the bottom surface of the top frame, and a mounting groove is formed between the inner ring and the outer ring, with the top end of the magnet assembly embedded in the mounting groove.

[0007] Furthermore, the outer ring includes a plurality of uniformly arranged limiting posts, and the diaphragm is provided with a plurality of vertical corrugated grooves, with the limiting posts embedded in the corrugated grooves at corresponding positions.

[0008] Furthermore, a vertical plate is provided on one side of the top surface of the base, and a limiting groove is provided on the outer ring of the top frame, with the top of the vertical plate embedded in the limiting groove.

[0009] Furthermore, the magnet assembly includes a magnet bracket and a plurality of magnetic strips mounted on the magnet bracket. The magnet bracket is provided with a slot, and the magnetic strips are embedded in the slot.

[0010] Furthermore, the magnet bracket has a cylindrical design, including an upper ring, a lower ring, and several connecting blocks.

[0011] Furthermore, the card slot is T-shaped, the magnetic strip is embedded in the card slot, and both its upper and lower ends extend into the upper and lower rings.

[0012] Furthermore, the diaphragm is arranged in a corrugated shape with multiple corrugated grooves with openings facing outward and inward, and the limiting post is embedded in two adjacent corrugated grooves with openings facing outward.

[0013] A loudspeaker including the aforementioned surround aerodynamic tweeter.

[0014] In summary, this invention features a fully pleated diaphragm designed around the magnet assembly, with the pleats evenly distributed around the base, and utilizes a ring magnet as the inductive drive core. This creates omnidirectional sound diffusion, allowing sound waves to spread synchronously 360 degrees. The surround sound structure effectively reduces sound directionality and enhances the uniformity of the sound field, resulting in a better user experience and application. This invention is highly practical and has significant potential for widespread adoption. Attached Figure Description
