Abstract

PROBLEM TO BE SOLVED: To enable eliminating the need for external charging and the replacement of batteries, by interlocking a generator with an ear speaker with a built-in winder, generating power when the ear speaker is unreeled and/or reeled, and thereby charging a secondary battery through a controller for charging. SOLUTION: A generator 7 is of small-sized rotary type, and charges a secondary battery 3 with power, induced in a coil by the rotation of permanent magnets, through a controller 8 for charging. The rotational shaft of the generator 7 is mechanically connected with a winder 6 for an ear speaker 4, so that the shaft will be rotated in interlock with the winder. Thus the generator is capable of generating power, when the ear speaker 4 is unreeled and/or reeled. The controller 8 for charging is for matching power generated in the generator 7 with the charging voltage and polarity of the secondary battery, and consists of a constant-voltage circuit and a rectifying element.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable electronic device.

[0002]

2. Description of the Related Art In a conventional portable electronic device, a primary battery or a rechargeable secondary battery has been used to secure its electric energy.

FIG. 2 is an explanatory view of a conventional portable electronic device having an ear speaker with a built-in main unit and a winder.

In FIGS. 1 and 2, reference numeral 1 denotes a portable electronic device such as a portable telephone, a portable video camera, a portable radio, a portable tape recorder, a portable television, a portable navigation system, a portable video viewer, and the like. 2 is the main body, 3 is an attached secondary battery, 4 is a built-in ear speaker with a winder, 5 is a cord for the ear speaker,
6 is a winder for storing the ear speaker in the main body,
Reference numeral 7 denotes a power generator added for the present invention, and reference numeral 8 denotes a charging controller for introducing the electric power generated by the power generator 7 into the secondary battery 3.

FIG. 2 shows a conventional portable electronic device having an ear speaker with a built-in main unit and a winder.
Is connected to a cord 5 for supplying an audio signal to a speaker and wound up by a winder 6. The winder 6 has a spring (not shown) in the form of a mainspring, stores energy when the ear speaker 4 is pulled out, and generates a winding force during storage. In the center of the winder 6, there is a slider (not shown) for connecting the audio signal from the main body 2 to the cord 5.

[0006]

However, in case the battery is depleted on the go, always carry a spare battery.
Alternatively, the amount of consumption has been measured and the use time has been limited or dealt with. Some mobile devices display the battery level, but this is not a radical solution. In other words, battery management has been an important issue in using portable devices.

[0007] The present invention provides a portable electronic device that can be returned to a usable state when there is no fear of running out of the battery even when going out, or when the battery is exhausted.

[0008]

In order to solve the above-mentioned problems, the present invention employs means for incorporating a small-sized generator into a portable electronic device. The generator is linked to an ear speaker with a built-in winder incorporated in the main body, generates power when the ear speaker is pulled out and / or stored, and charges the attached secondary battery via a charging controller.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram of a portable electronic device according to the present invention.

According to the present invention, as shown in FIG. 1, a generator 7 and a charging controller 8 are added to the conventional configuration of FIG.
Configuration. In FIG. 1, a generator 7 is a small rotary generator (not shown), and charges the secondary battery 3 via a charging controller 8 with electricity induced in a coil by rotation of a permanent magnet. On the other hand, a rotating shaft (not shown) of the generator 7 is mechanically connected so as to rotate in conjunction with the winder 6 of the ear speaker 4, and can generate power when the ear speaker 4 is pulled out and / or stored. It has become. The charging controller 8 is for adjusting the electricity generated by the generator 7 to the charging voltage and the polarity of the secondary battery, and includes a constant voltage circuit and a rectifying element (not shown).

[0012]

According to the present invention, power can be generated each time the ear speaker is used, and by storing the energy, in a portable radio or the like with small power consumption, external charging work and the like can be performed until the life of the secondary battery is exhausted. There is no need to change batteries. In addition, if the battery is low on the go when power consumption is high or the frequency of use of the ear speaker is infrequent and it is not possible to generate the amount corresponding to the power consumption and the battery runs out on the go, you can operate the ear speaker several times on the spot Since the battery can be charged, an unexpected situation can be avoided.
