AI Technical Summary

Technical Problem

The combination of dynamic speakers and dynamic iron speakers requires larger internal space on the space stack, resulting in larger size of the headphones, sacrificing the comfort of wearing.

Method used

A coil-iron headphone is designed, which includes a housing, a dynamic iron speaker and a dynamic coil speaker. The dynamic iron speaker is fixed in the sound guide tube, the sides are electrically connected to the motherboard, and the dynamic coil speaker is fixed in the housing. There are preset angles between the two and a specific interval length to optimize the spatial layout.

Benefits of technology

On the premise of ensuring sound quality, the space occupied by dynamic speakers and dynamic iron speakers is reduced, thereby reducing the size of the headphones and improving the wearing experience.

Abstract

The embodiment of the invention discloses a coil-iron earphone and a layout detection device of the coil-iron earphone. According to one specific embodiment, the coil-iron earphone comprises a shell, a moving-iron loudspeaker and a moving-coil loudspeaker, and the shell is provided with a sound guide tube; the moving iron loudspeaker is fixed in the sound guide tube; the side surface of the moving-iron loudspeaker is electrically connected to the main board of the coil-iron earphone; the moving coil loudspeaker is fixed in the shell; an included angle with a preset angle is formed between the moving iron loudspeaker and the moving coil loudspeaker; the center of the moving iron loudspeaker and the center of the moving coil loudspeaker are spaced by a first preset length in the horizontal direction. A second preset length is arranged between the moving-iron loudspeaker and the moving-coil loudspeaker, and the second preset length is measured in the direction perpendicular to the end face of the moving-coil loudspeaker; a third preset length is arranged between the end face of the sound guide tube and the center point of the end face of the moving coil loudspeaker. According to the embodiment, the wearing experience of the user can be improved.
