  • an audio player according to an embodiment of the present invention is provided with a main body 1 disposed on the rear of the neck of a user and two arms 2 extended from the main body 1 to two earphones 4 placed on ears of the user.
  • the earphones 4 has pads 5 covering the ears and ear hooks 3 hung on the ears.
  • Signal transmission lines connecting the main body 1 and the earphones 4 are built in or attached to the arms 2, so the audio player according to an embodiment of the present invention has a very compact structure without troublesome lines.
  • a disadvantage of the audio player according to the present invention is that the main body 1 is disposed on the rear of the neck of a user so that its weight is supported in a state contacted with the user' s skin.
  • the audio player according to the present invention has difficulties in being used as an audio player having mechanical parts such as a cassette deck and the like which are heavy as can be seen in a cassette tape player and so on, but is suitable for an audio player having only chip-shaped electronic components as can be seen in a radio, an MP3 player, or the like.
  • an audio player is structured as a reproduction- dedicated MP3 player using a flash memory F in which MP3 -formatted files are stored, and, preferably, further comprises an FM receiver.
  • Another problem occurring from a contact of the main body 1 to the skin of the neck is that sweat is easily penetrated into the main body 1.
  • the sweat is a corrosive liquid containing a saline matter so that the sweat causes a damage to electronic components easily.
  • a suitable absorptive pad such as velcro(a brand name) and so on is replaceable attached on a neck-touching portion of the main body 1.
  • the arms 2 become bent with respect to the main body 1 or the lengths of the arms 2 vary for the sake of convenient keeping.

  • the ear hooks 3 different from a conventional structure of FIG. 2, is upwardly extended through the interior of the ear phones 4 in a 7-lettered shape to be hooked from the front to rear.
  • the arms 12 are contacted with the rear portions of ears to cause skin diseases and the like when using the arms 12 for a long time, whereas, in the ear hooks
  • FIGs 5(A) and 5(B) are a side view and a plain view for showing wearing states of the audio player of FIG. 3, respectively.
  • the load due to the main body 1 is dispersed for the user not to feel much weight compared to a simple neck phone.
  • necessary keys 6 such as a push button and the like for controlling the audio player should be found only with a sensation of feeling in user' s hands since the main body
  • the keys 6 it is preferable for the keys 6 to be disposed on both sides of the main body 1 or to be provided on the ear phones 4 as shown in FIGs. 5(A) and 5(B).
  • the structure therefor will be in detail described later through FIG. 8.
  • FIG. 6 is a block diagram for showing the audio player of the FIG. 3.
  • MP3 files stored in the flash memory F are decoded through the MP3 decoder 1 10 under the control of the microprocessor 100 and then outputted to the output part 130 through the D/A converter 120, so that the structure becomes extremely simplified compared to a conventional MP3 player shown in FIG. 1 to reduce the cost.
  • Remaining reference numbers 150 and 140 denotes keys and a key input/output part, respectively.
  • the audio player according to an embodiment of the present invention does not have a separate interface so that MP3 files should be stored in the flash memory F in advance through a separate device. Therefore, a writer is indicated in FIG. 7.
  • the writer is a flash memory writer which may be found in the market.
  • An interface E is provided with a cable L and a connector N to be connected to a parallel port K and so on of a computer C, so that MP3 files stored in the computer C may be written to the flash memory F.
  • FIGs. 8(A) and 8(B) are side views for showing both sides of the neck phone as an embodiment of a key structure of the audio player of FIG. 3.
  • FIGs. 8(A) and 8(b) show a right and a left ear phone 4, respectively.
  • a user should find a desired key 6 thought only a sense of his hands, so that it is appropriate the number of keys 6 for the both ear phones 4 is at most not more than 2.
  • keys required for a general MP3 player are ON/OFF, PLAY, FF, STOP. REW, FR, volume, and so on, so that it is preferable for the keys 6 of the audio player according to an embodiment of the present invention to have the minimum number of keys with compatible functions.
  • the right ear phone 4 as in FIG. 8(A) is provided with a play key 6a and a stop key 6b, and the play key 6a may be functioned as PLAY when it is pressed once and as FF when it is pressed twice while the stop key 6b may be functioned as STOP when the audio player is in the state of PLAY and as ON/OFF when the audio player is in the state of STOP.
  • the left ear phone 4 as shown in FIG. 8(B) may be provided with a volume key 6c and an FM key 6d in case that an FM receiver is built in, to thereby sequentially select predetermined broadcasting stations in the FM receiver one by one every time the FM key 6d is pressed upon turning-on by the stop key 6b.
  • the volume key 6c steps up or down, in a digital control manner, the volume by a predetermined step every time it is pressed once.
  • any one of the keys 6a, 6b, and 6d is set to a shift key. For example, it may be considered that the volume is stepped down if the stop key 6b and the volume key 6c are pressed at the same time.

Abstract

L'invention concerne un baladeur pouvant être utilisé comme lecteur de fichiers musicaux MP3 et/ou récepteur FM. Un corps principal du baladeur se porte sur la nuque d'un usager, et deux bras allongés constituant des écouteurs sont maintenus sur les oreilles de l'usager par des crochets, sans fil de transmission du signal encombrant, ce qui confère au baladeur une portabilité et une utilité simplifiées.
