Headphones with headband made of elastic plastic material

7723484 12/01/77

The invention relates to a pair of headphones with a headband made of elastic plastic material connected earphones.

The accommodation of the cable for the electrical connection lines between the earphones prepares Trouble. On the one hand, the cables should be secured against being torn off over the head of one of the earphones to be led to others. On the other hand, accommodation should be as aesthetically pleasing as possible.

In known headphones in which the headband is off consists of two roughly parallel steel wires, the cable was routed from the left to the right earpiece placed between the steel wires and there was a connection in two places by an overmolded Plastic part. If you needed several wires, a hose was pulled over the steel wire, in which the cables were guided, with the formation of the head strap Up to now, the cables were made from a flat steel band above the steel band or in a laterally arranged one Profile hose guided. In all of these known arrangements, the attachment of the cables to the headband is only done in a few places and there must be enough cable length available in between, To avoid tearing or excessive tensioning of the cable during the elastic bending up or down of the headband to avoid.

The invention is based on the object of the cable * to be arranged between the hearing capsules in a headband made of elastic plastic so that it is aesthetically pleasing

appealing way about the gansae length without the Risk of tearing associated with the headband.

To solve this problem, it is proposed according to the invention for headphones of the type mentioned at the outset that that the electrical cables between the earphones are in an elastic opening of the headband neutral zone are attached in the headband. By inserting the cable with any number of services in one "; plastic bracket in the neutral zone ensures that the cable behaves neutrally in its expansion, that is, neither elongation nor compression occurs when the headband flexes or is widened.

Appropriate ways of attaching and securing the Cables on the headband are identified in the subclaims. Exemplary embodiments are described in more detail below with reference to the accompanying drawings. Show it:

Fig. 1 is a schematic view of a headphone,

FIG. 2, on an enlarged scale, a sectional view along the line A-A in FIG. 1,

FIG. 3 in a representation corresponding to FIG another execution format.

According to FIG. 1, the headphones consist of a headband 1 made of elastic plastic. The hearing capsules attached to the ends of the headband 1 are denoted by 2 and only indicated by dashed lines.

As can be seen in FIG. 2, the plastic headband 1 has an essentially rectangular cross section. Its zone, which is neutral with regard to bending up or down, is identified by a dash-dotted line, which is denoted by S. On one of the narrow sides, symmetrical to the neutral zone 3, a recess 4 with a circular cross-section is provided, which is used to receive a two-core cable 5 in the present case. The recess 4 comprises the cable 5 on more than half of its circumference, so that the cable 5 is held by clamping. On the narrow side opposite the recess 4, the headband 1 has an outer contour 6 which corresponds to the contour on the opposite side with the inserted cable 5. This gives the bracket with cable an aesthetically beautiful and symmetrical appearance.

In the embodiment according to FIG. 3, the same parts are provided with the same reference numerals. The only difference from the previous embodiment is that recesses 4 for receiving a cable 5 are provided here on both narrow sides of the headband 1. An attractive appearance can also be achieved thereby when the color of the outer jacket of the cable 5 relative to the color of the plastic of the headband is discontinued.
