The specific embodiment

In Fig. 1 and 2 of accompanying drawing, schematically drawn personal music device 10, this device 10 comprises commercially available music player 18, this music player 18 is MP3 player, MP4 player, i-Pod ^TMPlayer, CD Player, MiniDisc ^TMPlayer or DVD player, mobile phone, portable television or any other portable audio reproducing device.Described music player 18 comprises the stereo pocket jack 80 of standard, and the stereo pocket plug of a pair of earphone 11 is inserted into described stereo pocket jack 80 usually.

What the replacement pocket plug with earphone 11 like this directly was inserted into pocket jack 80 is to use interface equipment of the present utility model.For this purpose, the embodiment that describes in Fig. 1 and 2 comprises adapter sleeve 16, extends the cable with the pocket plug 17 that is used to be inserted into pocket jack 80 from this adapter sleeve 16.One or more button cells 70 are inserted in as shown in Figure 2 the adapter sleeve, and are provided with and have the cord of connection easily 60 of connecting flange as shown in the figure.

Extended from described adapter sleeve 16 is a pair of short rope 14 that extends to connector 13, and a pair of stereophone 11 is connected in described connector 13 by its cable 12 separately.Described connector 13 will typically be connected wearer's neck back, so that each short rope in wearer's collar area obviously as seen.Headphone cable 12 separately will extend on the corresponding earphone of the left and right ear that is inserted in the wearer from the connector 13 of wearer's neck back.

Described each short rope 14 typically comprises the plastic sheath of transparent flexible, by in the described plastic sheath one or two, electrical voice-frequency cable extends from adapter sleeve 16, along described plastic sheath, a plurality of LED15 separate each other in this sheath and get back to adapter sleeve 16 by the connection electrically of described short rope.

In Fig. 3 and 4, drawn optional embodiment.In this embodiment, be not that LED is separated each other along short rope 14, but pair of LEDs is arranged on adapter sleeve 16 places, and described short rope 14 itself is flexible fiber optic cables, or the light-passing plastic sheath of one or more optical fiber flexibility of extending within it.Which kind of mode no matter, except printing opacity, described short rope also must be transported to electric audio signal on earphone 11, and for this purpose, at least one in them will comprise electric wire.Typically, described optical fiber is for spreading all over its length from the radiative type of its outer surface.This can provide by the coarse outer surface on the described optical fiber, this coarse outer surface can steam by the outer surface to fiber, scrapes, cutting, blasting treatment, spray paint, etching or heat treatment realizes.As selection, the optical fiber that can select only to transport light to their end or mainly transport light to their end, and these optical fiber can be cut at the different length place, so that described end along short rope at interval, thereby are sending light along the position of described short spaced points of restricting.As another selection, in manufacture process, in described short rope, can be provided with minute bubbles or pigment capsule, not only arrive its other end so that put on the light of an end of optical fiber, and be reflected, thereby allow optical fiber or cable to be illuminated in every way by described bubble or pigment capsule.

Wish described LED and glimmer synchronously by the music of earphone 11 playbacks.This can realize by one or more methods.A kind of described method in Fig. 5 and 6 by example.Fig. 5 has shown a pair of earphone 11.Each earphone is included in the loudspeaker or the acoustic transducer 30 of cushion 31 back.At an earphone place, be provided with the microphone 32 that picks up the sound that sends from described loudspeaker 30.This microphone 32 is connected by the electric wire that passes cable 12 gets back to the circuit that is positioned at adapter sleeve 16.The example that has shown sort circuit among Fig. 6, this circuit comprise amplifier chip 40 and lighting controller chip 50.Described circuit will can not be described in detail, because we make the parts on it discern with standard symbol and chip marking numeral in the drawings.In the embodiment of Fig. 6, the audio signal that is received by pocket plug 17 can only pass to loudspeaker 30.The sound that sends from one of described loudspeaker 30 picks up and is fed back to amplifier 40 by microphone 32, is transported to lighting controller 50 by the described signal of circuit from described amplifier 40.The variable current that amplifier 40 amplifies that is based on from described lighting controller 50 outputs.The variable current output of supplying with by a plurality of controllers is connected in different LED, so as to provide different light output (for example, bright or dim, open or close).

Described lighting controller 50 does not need to rely on microphone apparatus, replaces to rely on the signal of telecommunication that receives via pocket plug 17.The circuit of drawing in Fig. 7 illustrates a kind of method, and wherein the signal of telecommunication at pocket plug place not only is sent to earphone speaker 30, and is sent to amplifier 40.Lighting controller 50 and amplifier 40 are with as its same mode co-operation in the embodiment of Fig. 6.

Should be appreciated that and person of ordinary skill in the field's modification and change clearly do not thought exceed scope of the present utility model.For example, illumination does not need to be limited to short rope.Replace and/or except throwing light on described short rope, optical transmitting set can be arranged in the adapter sleeve 16, can be arranged in the earphone itself, can be arranged in pocket plug or other the connector or can be arranged in the audio player itself.
