The power supply unit 17 supplies power to circuits in the main body 1 and a display unit. The light receiving unit 18 determines an infrared pulse train incident from the light receiving window 1c and gives an operation instruction to the microcomputer 12.

In the semiconductor memory card 3, the terminal 3a
Is connected to the memory control unit 3b, and the memory control unit 3b controls reading of data from the memory element 3c and control of copyright protection based on a request from the main unit 1.

FIGS. 4A and 4B are external perspective views of the semiconductor memory card 3 used in the present embodiment, wherein FIG.
Is a view from the front. As an example of this embodiment, for example, a stamp size having a size of width 24 × length 32 × thickness 2.1 (mm) is used. With a capacity of 32 MB, it is possible to reproduce tens of minutes of audio depending on the compression ratio. In the memory card 3, the upper body 31 of the memory card and the lower body 32 of the memory card are combined, and the semiconductor memory element 3c and the memory control unit 3b are accommodated in the internal recess. A notch 33 is provided on a side surface of the upper body 31 of the memory card, and a write enable / disable setting element 34 is slidably fitted to the guide 35, and FIG. Then, the user can put a claw on it and slide it in the direction of arrow A, thereby making it possible to write data as shown in FIG. If it is a memory exclusively for reproduction, it may be fixed to the state of FIG. A plurality of terminals 36 are provided on the terminal portion 3a at one end in the longitudinal direction, and a reverse insertion preventing portion 37 is provided beside the terminal 36. The terminal 36 engages with the internal shape of the main body and can be inserted to the end even if it is inserted upside down. The terminal 36 and the connector of the main unit 1 are not electrically connected. Body 3 on memory card
The central portion of 1 is recessed one step from the peripheral portion, and forms a label attaching portion 38.

The operation is as described above, and the operation will be described below. First, the battery cover lid 7 is opened by sliding the battery cover lock knob 7b, and a predetermined battery is stored in the internal battery case. If the battery is thin and flexible, it can be stored along the headband portion 5 even if it is slightly curved. The battery case cover 7 is closed, and the battery case cover 7 is locked by the battery cover lock knob 7b. Thus, the headband unit 5 can be effectively used not only as a function of simply connecting the left and right speakers but also as a storage space for batteries.

The semiconductor memory card 3 is inserted into the insertion section 2 of the main body 1.
1B is mechanically fixed to the main body 1 by the insertion pressure and a plurality of terminals of the terminal 3a are electrically connected to the connector 11 inside the main body 1. The headband section 5 is pushed outward and attached to both ears. At this time, the above-mentioned sensor detects that the mounting state has been reached, and the power switch is turned on. Then, holding the remote controller 9, the light receiving window 1c of the main body 1 is held.
Is operated, the infrared ray incident from the light receiving window 1c is analyzed by the light receiving section 18 to provide an instruction to the microcomputer 12 according to the result. If the instruction is reproduction, the microcomputer 12 is connected to the connector 11 Instructs the memory controller 3b from the terminal 3a of the semiconductor memory card 3 to access the required address in the memory element 3c, fetches the data, sends it to the compression / expansion circuit 13, expands the compressed data, and The digital data is converted into analog data by the / A conversion circuit 14, amplified by the low-frequency amplifier 15, and can be heard by the speakers 4a and 6a. The use of the remote controller 9 facilitates the operation even when worn on the head.

As another method of the remote controller 9, the main unit 1 may be connected to the remote controller by a lead wire instead of wireless. In that case, it becomes easy to provide a display unit on the remote controller side.

The power supply 17 supplies power to the above circuits and the display unit 16. To stop the reproduction, the operation unit 9a of the remote controller 9 may be pressed again. The operation unit 9a
Is slid once in the direction of the arrow A1 to the beginning of the next tune currently being reproduced, and is reproduced. Each further slid is jumped to the beginning of the next tune number one by one. Each time the operation section 9a is slid once in the direction of the arrow B1, it goes to the beginning of the currently reproduced music piece, and each time it is slid once, it jumps to the beginning of the previous music piece number. Each time the operation unit 9a is slid once in the direction of the arrow C1, the volume slightly increases, and the operation unit 9a is moved once by the arrow D1.
Each time you slide in the direction, the volume will decrease slightly. The number of operation units and the functions that can be operated are merely examples, and can be changed as needed.

As described above, according to the present embodiment, the speaker section is provided on both sides of the headband, and one of the sections is provided with the memory card storage section and the reproducing means for reproducing the audio data recorded on the stored memory card. And
Since the audio signal reproduced by the reproducing means is acoustically output by the speaker unit, all of the recording medium including the semiconductor memory card can be integrally configured as a headphone device, so that it is convenient to carry and easy to use. You can enjoy the playback without getting in the way.

A radio / television wave receiving circuit may be added to this embodiment so that they can be switched to be audible.

In this embodiment, the operation is performed by the remote controller. However, an operation location may be provided in or around the main body 1 and operated there.

Since the display of the reproduction status and the like cannot be seen during reproduction if provided on the main unit, a display unit is provided on the remote controller so that bidirectional communication with the main unit 1 is enabled to display the operation state. Is also good. In that case, if the remote controller is connected not by radio but by a lead wire, bidirectional communication is easy.

Further, in the present embodiment, the reproduction apparatus has been described. However, a recording / reproducing apparatus may be provided by adding a microphone, an A / D conversion circuit, a compression circuit, a recording temporary memory, and the like.
