Description

Technical Field

[0001] This utility model relates to a spring structure suitable for moving iron units. Background Technology

[0002] As a mid-to-high-end product on the market, balanced armature earphones offer advantages over dynamic driver earphones, including a more stable frequency response curve, higher sensitivity, deeper insertion into the ear, and lower resistance. Therefore, they are increasingly accepted, valued, and favored by music enthusiasts who prioritize sound quality. The balanced armature driver is the key transducer in balanced armature earphones. Existing balanced armature drivers generally include a shielded shell, a driver assembly inside the shell, and a diaphragm. The driver assembly mainly consists of a yoke, magnets, a coil, a balanced armature, and a guide pin. A magnet is located on the upper and lower inner walls of the yoke, and the coil is fixed to the yoke. The balanced armature is generally U-shaped, with one end fixed to the yoke and the other end passing through the coil and the two magnets, and connected to the diaphragm via the guide pin. The shell also has a sound outlet that connects the diaphragm and the shell to the front cavity. When the moving iron unit is working, the sound signal is transmitted to the coil in the form of an alternating current signal. The induced magnetic field generated by the coil is conducted to the balance armature. The balance armature is attracted or repelled by the inherent magnetic field generated by the upper and lower magnets and vibrates. The vibration is transmitted to the diaphragm through the guide needle. The diaphragm vibrates and produces sound, which is output to the outside from the sound hole.

[0003] As can be seen from the structure and working principle of balanced armature drivers, the vibration of the balance armature needs to be transmitted to the diaphragm through a guide pin. In existing balanced armature drivers, the balance armature is connected to the diaphragm through a single guide pin, and the diaphragm vibrates around one side as an axis. This reduces the efficiency of the diaphragm in pumping air. However, if the diaphragm could vibrate in parallel, its vibration efficiency could be improved, which would also improve the sound quality of the balanced armature driver.

[0004] A search revealed a patent: a moving iron unit with dual guide pins (CN201620246901.3), comprising a housing, a drive assembly, and a diaphragm. The diaphragm and housing form a front cavity, and the housing has a sound outlet hole communicating with the front cavity. The drive assembly is located inside the housing and connected to the diaphragm via guide pins for driving diaphragm vibration. The guide pins are divided into a first guide pin and a second guide pin, which are separate from each other and both connected to the diaphragm. The first and second guide pins are formed by bending two forked or overlapping legs located at the vibrating end of the balance armature. This structure is connected by a single molding process, limiting the use of different structures, resulting in low applicability. Furthermore, replacement requires replacing the entire unit, increasing costs.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of spring structure suitable for moving iron units, making it more valuable for industrial applications. Utility Model Content

A positioning recess is provided on the side of the extension protrusion 2. A first fixed support 3 is connected to the extension protrusion 2. The first fixed support 3 has a concave structure. The recess of the concave structure of the first fixed support 3 is connected to the positioning recess of the extension protrusion 2. A guide pin 4 perpendicular to the first fixed support 3 is connected to the center of the first fixed support 3. A second fixed support 5 is connected to the extension protrusion 2. The second fixed support 5 has an L-shaped structure. The L-shaped structure of the second fixed support 5 is connected to the first fixed support 3 and forms a "+" shape.

[0024] The reed body 1 described in this utility model includes a U-shaped reed or an E-shaped reed, which allows for the installation of different structures and improves applicability.

[0025] In this invention, the extension protrusion 2 and the spring body 1 are integrally formed, which improves its strength and ensures the stability and durability of the product.

[0026] In this invention, the first fixed support 3 and the second fixed support 5 are integrally formed, and the bottom surfaces of the first fixed support 3 and the second fixed support 5 are welded to the extension protrusion, thereby improving the overall robustness.

[0027] In this invention, the guide pin 4 is welded at the center where the first fixed support 3 and the second fixed support 5 intersect.

[0028] The specific working principle of this utility model has been disclosed in the existing patent: a moving iron unit with double guide pins (CN201620246901.3), and will not be repeated here.
