Description

Technical Field

[0001] The utility model belongs to the technical field of diaphragm frames, and in particular relates to an integrated diaphragm frame structure suitable for the diaphragm of a planar magnetic speaker unit. Background Art

[0002] The working principle of a planar magnetic speaker is to utilize a thin film suspended between two parallel strong magnets. This thin film is inlaid or coated with a conductive coil. In order to maintain the shape and tension of the thin film, a frame is required.

[0003] The design of the frame is crucial. It not only needs to provide sufficient support but also minimize interference with the movement of the thin film. Generally, the frame is made of metal or other tough materials and must maintain extremely high flatness to ensure that the thin film can move uniformly in the magnetic field, thereby generating high-quality sound. The diaphragm frame of a traditional planar magnetic speaker unit and its connected signal input interface are of a split design, which not only increases the complexity of the assembly process but also leads to an increase in the thickness of the speaker unit. At the same time, the diaphragm of the planar magnetic speaker unit must maintain uniform tension in the magnetic field so that the entire diaphragm surface can respond evenly to the audio signal. If the frame does not have sufficient rigidity to support the diaphragm uniformly, the situation of uneven diaphragm tension may occur.

[0004] Therefore, it is necessary to innovate the design of the diaphragm frame structure to simplify the assembly process, reduce the thickness of the speaker unit, and ensure uniform diaphragm tension to improve the quality of audio output. Summary of the Utility Model

Apparently, the described embodiments are some, but not all, of the embodiments of the utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] This embodiment provides an integrated diaphragm frame structure applicable to the diaphragm of a planar magnetic speaker unit. Refer to Figure 1 , which includes a frame assembly, a signal input interface 104, and a diaphragm 102; the frame assembly includes a first frame 101 and a second frame 103;

[0026] The diaphragm 102 is clamped and installed between the first frame 101 and the second frame 103, and the signal input interface 104 is installed on the frame assembly.

[0027] In this embodiment, the first frame 101 is a circular ring structure.

[0028] As a preferred solution, the second frame 103 is a circular ring structure.

[0029] In addition, a clamping groove is provided on the frame assembly, and the signal input interface 104 is installed on the frame assembly through the clamping groove.

[0030] As a preferred solution of this embodiment, a contact is provided at the clamping groove, and the signal input interface 104 is connected to the contact.

[0031] Furthermore, the frame assembly serves as a circuit board, and the signal input connection 104 is soldered to the frame assembly.

[0032] Finally, the cable part of the diaphragm that is not effectively driven is preferably fixed within the frame assembly. Specifically, the cable part that is not effectively driven is the part that is not perpendicular to the magnetic field / magnetic induction line and the vibration direction.

[0033] In this embodiment, the frame assembly of the diaphragm 102 and the signal input interface 104 adopt an integrated design. By establishing contacts on the first frame 101 and the clamping groove as an assembly limiting structure, the signal input interface 104 is directly set in the frame structure, thereby reducing the overall thickness and simplifying the assembly process.

[0034] In addition, the diaphragm 102 frame of this embodiment can be made of a composite material with a high damping coefficient. Such materials can effectively absorb and dissipate the energy generated by the movement of the diaphragm 102, reducing unnecessary resonance. At the same time, in order to ensure that the diaphragm 102 can maintain uniform tension in the magnetic field, some of the circuit traces on the diaphragm 102 can be cleverly extended to the inside of the frame assembly. These design details work together to make the sound quality purer and more stable.

[0035] Based on the technical solution of this embodiment, it is possible to significantly reduce the thickness of the planar magnetic speaker unit, simplify the assembly process, and reduce resonance and improve the sound quality by using a composite material with a high damping coefficient, thereby improving the overall performance of the planar magnetic speaker unit without increasing costs.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
