Wireless headphone integrated with an adjustment control device
A wireless headphone integrated with an adjustment control device includes a headphone, a tuning unit having a base disposed on a side of the headphone containing an ear muff, a rotatable tuning shaft protruded from the base and coupled to a knob, a direction changing unit having a through hole at the middle of the direction changing unit and rotably coupled to the base, such that the tuning shaft is passed through the through hole, a microphone unit movably coupled to the direction changing unit, such that the microphone unit can be rotated, extended, contracted or adjusted by the direction changing unit. Therefore, the wireless headphone integrated with an adjustment control device achieves the effects of simplifying the assembly structure, lowering the manufacturing cost, and beautifying the appearance of the headphone.
1. A wireless headphone integrated with an adjustment control device, comprising:
a headphone;
a tuning unit, including a base disposed on a side of the headphone containing an ear muff, and a tuning shaft disposed at the base and coupled to a fixing element and a knob sequentially;
a direction changing unit, having a through hole, and turnably coupled to the base of the tuning unit, and the tuning shaft of the tuning unit passing through the through hole and connecting with the fixing element and the knob; and
a microphone unit, including a bendable link rod, a microphone connected to a front end of the link rod, and a signal line connected to the microphone, and a rear end of the link rod being slidably coupled to the direction changing unit;
wherein the base of the tuning unit includes a plurality of concave holes arranged in a semicircular shape, and the direction changing unit includes at least one protrusion disposed at a corresponding position and embedded into the concave hole;
wherein the base of the tuning unit has an arc hole arranged in a semicircular shape, and the signal line of the microphone unit is passed through the direction changing unit and the arc hole and connected to a wireless transmitter.
2. The wireless headphone integrated with an adjustment control device as recited in claim 1 , wherein the direction changing unit includes a containing hole disposed at an external end of the through hole and having a larger diameter than that of the through hole, and the tuning shaft is passed through the through hole and the containing hole, and the fixing element and the knob are coupled to the tuning shaft in the containing hole, such that the direction changing unit can be rotably coupled onto the base of the tuning unit.
3. The wireless headphone integrated with an adjustment control device as recited in claim 2 , wherein the direction changing unit includes a first rotating element and a second rotating element abutted against one another, and the through hole is disposed separately at middle sections of the first rotating element and the second rotating element, and the containing hole is disposed at an external end of the through hole of the second rotating element.
4. The wireless headphone integrated with an adjustment control device as recited in claim 1 , wherein the direction changing unit includes a first rotating element and a second rotating element abutted against one another, and the through hole is disposed separately at middle sections of the first rotating element and the second rotating element, and one or more slide slots are disposed separately on an internal abutted surface of the first rotating element and second rotating element, and fixed to the link rod of the microphone unit.
5. The wireless headphone integrated with an adjustment control device as recited in claim 4 , wherein the link rod is comprised of one or more metal bars, and a rear end of the link rod is clamped into the slide slot of the direction changing unit.
6. The wireless headphone integrated with an adjustment control device as recited in claim 1 , wherein the headphone comprises two ear muffs and a head band connected between the two ear muffs, and one of the ear muffs includes a signal line connected to a wireless transmitter.
