Abstract

(57) [Abstract] [Purpose] To provide a portable alarm that causes a specific sound or a changed sound to be generated from headphones when a preset time elapses and notifies that the preset time elapses. [Structure] The portable alarm has a structure in which an acoustic signal output from an acoustic signal generation unit is amplified by an acoustic signal amplification unit 18 to operate the headphones 3. The configuration is such that a time setting unit 7 that sets a required time and an acoustic signal that notifies that when the time set by the time setting unit 7 has elapsed are input from the acoustic signal generation unit 16 to the headphones 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a portable alarm that causes a headphone to generate a specific sound or a changed sound when a preset time elapses and notifies the user.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, there are various types of portable radios and portable tape recorders equipped with headphones, which are widely used when commuting to work or attending school using a train, or traveling. ing.

[0003]

[Problems to be solved by the device]

 In general, when traveling by train, it is estimated that the train is approaching the drop-off station based on the time required between the embarkation / departure stations or the time from the current time to the estimated arrival time at the drop-off station, and the station name is used to get off. I know the station. However, when using a train for a relatively long time, we often sleep while riding, and in such cases we often overrun. Also, when the train is crowded, it is not easy to check the station name, which is very inconvenient.

In view of the above situation, the present invention sets a required time in advance from the current time before, after, or before boarding, and puts the headphones on the ear. It is an object of the present invention to propose a portable alarm that can reliably notify that by approaching sound when approaching or arriving, and can prevent inadvertent overtaking.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is configured as follows. That is, in a portable audio device that amplifies the acoustic signal sent from the acoustic signal generation unit by the acoustic signal amplification unit and operates the headphones, when the time set by the time setting unit and the time set by the time setting unit elapses. This is a portable informing device configured to input an acoustic signal for informing this to the headphones from the acoustic signal generating section via the above path.

[0006]

[Action]

 According to the portable alarm device of the present invention, by simply setting the required time in advance in the time setting unit and putting the headphones on the ears, the acoustic signal is input to the headphones when the set time has elapsed, and the specific sound is output. Alternatively, a sound different from usual is used to notify the user.

【Example】

 An embodiment will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main body of a portable alarm device, which is of a size suitable for carrying in a pocket, for example, and a headphone 3 is attached to and detached from a headphone connecting section 2. It is free. 4 is a volume control dial that also serves as a power switch, 5 is a radio AM / FM broadcast switching switch, and 6 is a broadcast channel selection dial. The main body 1 has a reproducing function using a cassette tape (not shown). Reference numeral 7 is a time setting section, and pressing the + side increases the set time, and pressing the-side decreases the set time to zero. Reference numeral 8 is a power supply battery, and 9 is an attachment portion for a hand strap.

The main body 1 is provided with a time display section 10 such as a liquid crystal display, and the time display section 10 displays a set time band in a range of 0 to 60 minutes. The time required for setting by the operation of the time setting unit 7 is displayed. Reference numeral 11 denotes a station name display section of the train. This station name display section 11 displays, for example, a specific section in a specific direction on a specific route. In the example of getting on from A station and getting off at B station, The station name corresponds to the scale 0 on the time display unit 10, and the B station name corresponds to the scale (55 minutes in the figure) corresponding to the time required from the A station.

Since the station name display section 11 of the train displays a specific section in a specific direction on a specific route, in order to have versatility as a portable alarm, the specific section in a specific direction on the specific route is displayed. It is advisable to prepare various types of plates to be used and allow the user to select the appropriate plate according to the usage situation.

FIG. 2 illustrates a circuit configuration of the portable alarm device shown in FIG. In FIG. 2, reference numeral 12 is an AM receiving circuit section of a radio, 13 is an FM receiving circuit section of the same, 14 is a reproducing circuit section of a cassette tape, 15 is a driving section thereof, and 16 is an acoustic signal generating section (buzzer oscillating section). Reference numeral 17 denotes an input switching circuit. The input side of the input switching circuit 17 includes an AM receiving circuit section 12 of the radio, an FM receiving circuit section 13, a reproducing circuit section 14 of the cassette tape, a driving section 15 thereof, and an audio signal. The generator 16 is connected. Reference numeral 18 is an acoustic signal amplifier, and the output signal of the input switching circuit 17 is amplified by the acoustic signal amplifier 18 and input to the headphones 3. Reference numeral 19 denotes a notification function setting circuit unit, which outputs a time signal set by the operation of the notification function setting operation unit 19 connected thereto to the time display unit 10. The notification function setting circuit unit 19 has a built-in power supply and is configured to supply power to each unit.

In order to use the portable alarm configured as described above, before or after boarding the train, or at an appropriate time within 60 minutes before the scheduled arrival time at the getting-off station B, The required time is calculated, the time is set by operating the time setting unit 7, and the time is displayed on the time display unit 10. In the example shown in the figure, when getting on at station A displayed on the station name display section 11 and getting off at station B, the band setting on the time display section 10 of the time setting section 7 should correspond to station B. The required time of 55 minutes can be set easily and surely only by operating. The notification by sound is performed by a specific sound that becomes an alarm such as a buzzer sound, or by generating a changed sound that is clearly different from the radio reception or the tape playback state. In order to cancel the notification function and enter the radio reception or tape reproduction state, the time setting unit 7 may reduce the time to zero. The portable alarm according to the present invention is not particularly limited to use when getting on a train. It can be used in various ways.

[0012]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. You can set the required time in advance from the current time before, after, or before boarding, and just put the headphones on your ears, and use a notification sound to notify you when a train approaches the drop-off station or when you arrive. It can be surely notified, and it is possible to prevent accidental overtaking.
