[0002] OWS (OpenWearable Stereo) speakers are speakers with an open design, primarily used in OWS headphones, which are open-ear wearable stereo headphones. OWS headphones do not need to be inserted into the ear during use, thus freeing the ear canal.
[0003] Existing OWS loudspeakers, due to the influence of their multi-folded diaphragm structure, experience asynchronous movement between the center and edge of the diaphragm during high-stroke conditions. This can easily lead to low-frequency diaphragm reverberation, resulting in abnormal sounds in the low frequencies and causing sound distortion. Summary of the Invention

The flange bracket 5 has multiple air passages 9 communicating with the first cavity 8 and the tuning through hole 7.
[0022] The dual-copper-ring OWS loudspeaker structure features airflow holes 9 that facilitate internal airflow. The double-copper-ring diaphragm 6 is connected to the frame 1 and flange-type bracket 5, simultaneously supporting it and ensuring more balanced axial vibration. Furthermore, the dual-copper-ring structure of the diaphragm 6 ensures stability during large-amplitude vibrations, preventing distortion caused by uneven vibration and further optimizing sound. In this embodiment, four airflow holes 9 are arranged in a ring at intervals on the flange-type bracket 5.
[0023] Preferably, the bottom of the flange bracket 5 extends a limiting shaft 10 that engages with the inner ring wall of the upper magnetic ring 4 to prevent the flange bracket 5 from shaking and causing adverse effects on the double copper ring diaphragm 6.
[0024] Preferably, the dual copper ring OWS loudspeaker structure further includes an outer magnet 11 attached to the lower magnetic plate 2, an outer magnetic ring 12 attached to the outer magnet 11, and a voice coil 13 attached to the dual copper ring diaphragm 6.

The diaphragm body 61 includes an outer ring portion 611, a first folded ring portion 612, a second folded ring portion 613, and an inner diaphragm portion 614 connected sequentially from the outside to the inside. The outer copper ring 62 is attached to the bottom of the outer ring portion 611, and the inner copper ring 63 is attached to the bottom of the inner diaphragm portion 614. The frame 1 and the flange bracket 5 connect the outer copper ring 62 and the inner copper ring 63 respectively, which simultaneously support the double copper ring diaphragm 6, making the axial vibration of the double copper ring diaphragm 6 more balanced. During large amplitude or low-frequency high-stroke vibration, the diaphragm's movement amplitude increases. The combined action of the outer copper ring 62 and the inner copper ring 63 achieves bidirectional positioning of the double copper ring diaphragm 6, optimizing the vibration sound.
[0026] Preferably, the top of the flange bracket 5 has a limiting protrusion 16 that cooperates with the inner ring wall of the inner copper ring 63.
