technical field

The utility model relates to an earphone (headset), such as an earphone (earphone) or a headphone (headphone). In particular, but by no means exclusively, the invention relates to a cable interface installed between headphones and personal audio equipment, wherein the interface provides lighting features.

Background technique

Personal/portable music players such as MP3/MP4 players, CD players, and radios include headphones connected to them by cables. In public places, users of these devices are often overly affected by dangerous situations, as music input directly into the ear canal may overwhelm ambient noise - which may otherwise warn the user to take evasive action. For example, a user may not hear the screeching of tires of a motor vehicle when walking across a pedestrian crossing. In this case, unintentional will mainly rely on the reaction of the motor vehicle driver.

Also, the cables themselves often lack distinguishing features and are generally uninteresting.

Detailed ways

In Figures 1 and 2 of the accompanying drawings, a personal music device 10 is schematically depicted comprising a commercially available music player 18 which may be an MP3 player, MP4 player, i - Pod ^™ player, CD player, MiniDisc ^™ player or DVD player, mobile phone, portable TV or any other portable audio playback device. The music player 18 includes a standard stereo mini jack 80 into which the stereo mini plugs of a pair of headphones 11 are normally plugged.

Instead of directly inserting the pocket plug of the earphone 11 into the pocket jack 80 in this way, the interface device of the present invention is used. For this purpose, the embodiment depicted in FIGS. 1 and 2 comprises a connection sleeve 16 from which extends a cable having a mini-plug 17 for insertion into a mini-jack 80 . One or more button cells 70 are inserted into the connection sleeve as shown in Figure 2, and a convenient connection string 60 is also provided with connection lugs as shown.

Extending from said connection sleeve 16 are a pair of short cords 14 which extend to a connector 13 to which a pair of stereo headphones 11 are connected by their respective cables 12 . The connector 13 will typically be attached to the back of the wearer's neck so that the individual lanyards are clearly visible in the wearer's collar area. A respective earphone cable 12 will extend from a connector 13 on the back of the wearer's neck to a respective earphone plugged into the wearer's left and right ear.

Said respective short cords 14 typically comprise transparent flexible plastic sheaths, through one or both of said plastic sheaths, electrical audio cables extend from connector sleeves 16, along said plastic sheaths, more The LEDs 15 are spaced apart from each other within the sheath and are electrically connected back to the connection sleeve 16 via the short cord.

In Figures 3 and 4, alternative embodiments are drawn. In this embodiment, instead of separating the LEDs from each other along the short cord 14, a pair of LEDs are provided at the junction sleeve 16, and the short cord 14 itself is a flexible fiber optic cable, or one or more A flexible, light-transmissive plastic sheath within which optical fibers extend. Either way, in addition to light transmission, the short cords must also carry electrical audio signals to the earphones 11, for which purpose at least one of them will contain wires. Typically, the optical fiber is of the type that emits light from its outer surface throughout its length. This may be provided by a roughened outer surface on the fiber, which may be achieved by steaming, scraping, cutting, sandblasting, painting, etching or heat treating the outer surface of the fiber. Alternatively, fibers may be selected that transmit light only or primarily to their ends, and these fibers may be cut at different lengths so that the ends are spaced along the lanyard so that Light is emitted at locations at spaced points along the lanyard. As another option, during the manufacturing process, small air bubbles or pigment pockets may be placed in the short rope so that light applied to one end of the optical fiber not only reaches its other end, but is reflected through the air bubbles or pigment pockets , allowing fibers or cables to be illuminated in various ways.

It is desirable that the LED blinks in sync with the music played back by the earphone 11 . This can be done in one or more ways. One such method is illustrated in FIGS. 5 and 6 . FIG. 5 shows a pair of earphones 11 . Each earphone includes a speaker or sound converter 30 behind a cushion 31 . At one earphone, a microphone 32 that picks up sound emitted from the speaker 30 is provided. The microphone 32 is connected back to the circuitry within the connector sleeve 16 by wires passing through the cable 12 . An example of such a circuit is shown in FIG. 6 , which includes an amplifier chip 40 and a lighting controller chip 50 . The circuit will not be described in detail, since in the drawings we have identified the components on them with standard symbols and chip designation numbers. In the embodiment of FIG. 6, the audio signal received by the mini-plug 17 can only be directed to the speaker 30. As shown in FIG. Sound from one of the speakers 30 is picked up by a microphone 32 and fed back to an amplifier 40 from which the signal is sent to a lighting controller 50 through an electrical circuit. The output from the lighting controller 50 is a variable current amplified based on the amplifier 40 . A variable current output supplied by multiple controllers is connected to different LEDs to provide different light outputs (eg, bright or dim, on or off).

The lighting controller 50 need not rely on a microphone device, but instead may rely on electrical signals received via the mini-plug 17 . The circuit drawn in FIG. 7 illustrates a method in which the electrical signal at the mini-plug is not only routed to the earphone speaker 30 but also to the amplifier 40 . Lighting controller 50 cooperates with amplifier 40 in the same manner as it does in the embodiment of FIG. 6 .

It should be appreciated that modifications and changes obvious to those skilled in the art are not to be considered as departing from the scope of the present invention. For example, lighting need not be limited to short cords. Instead and/or in addition to lighting with the short cord, a light emitter could be located in the connection sleeve 16, in the headset itself, in a pocket plug or other connector, or in the audio player in itself.
