Abstract
A retractable headphone connection structure includes two connection supports which are slidably connected with each other in a sliding connection direction. One of the connection supports has a plurality of first magnetically attractive portions arranged at intervals along the sliding connection direction. The other of the connection supports has a second magnetically attractive portion. Therein, the two supports relatively slide to make the second magnetically attractive portion slide over the plurality of first magnetically attractive portions to generate a magnetic attraction force between the second magnetically attractive portion and one of the first magnetically attractive portions that is opposite to the second magnetically attractive portion. The magnetic attraction force positions the first connection support and the second connection support. A head-mounted audio device includes a headphone and the above retractable headphone connection structure. The headphone is disposed on one of the connection supports.
