Abstract

PROBLEM TO BE SOLVED: To prevent the action by re-directing an attention of a suspicious person approaching from behind or the like to another object.SOLUTION: A portable type crime prevention alarm device 10 previously stores a repelling sound such as, for example, a wing slapping sound of a mosquito in a storage part 26. When a prescribed alarm setting operation is performed by an alarm setting switch 14, a control part 24 reproduces the repelling sound such as the wing flapping sound of the mosquito and the like by a reproducing part 28 to be repeatedly output from a speaker 30, thereby diverting the suspicious person's attention. The control part 24 makes the repelling sound repeatedly output by changing an amount of the reproduced sound and a pause time at random. Thus, for the repelling sound as the wing flapping sound of the mosquito, for example, a natural feeling is created.

Description

The present invention relates to a portable crime prevention alarm device for dealing with a suspicious person by sound output.

  In recent years, crimes targeting vulnerable people, such as women, children, and the elderly, have become a social problem, especially when women are approaching from behind, especially when women pass through unpopular places. Even if you are not a suspicious person, there is a daily situation where you are driven by strong anxiety.

  There is a security buzzer as a product for preventing such crimes targeting the weak. When a string or button is operated in an emergency, the security buzzer sounds a loud alarm sound, threatens the suspicious person, and informs the people in the vicinity that an emergency has occurred.

  In the case of a security buzzer, when a suspicious person is attacked or is about to be attacked, the string and button of the security buzzer will be operated. Since it is assumed that the crime prevention buzzer cannot be operated immediately, a device that does not require special operation and that sounds an alarm sound when the ambient sound voltage level is higher than a predetermined level has also been proposed. Yes.

[Appearance of security alarm device]
FIG. 1 is an explanatory view showing the appearance of a portable crime prevention alarm device according to the present invention. In FIG. 1, the security alarm device 10 is provided with an acoustic hole 16, a display unit 18, and an alarm switch 20 on the front side of the main body 12, a warning setting switch 14 is provided on the side surface of the main body 12, and a strap attachment portion on the upper part of the main body 12. 22 is provided.

  The warning setting switch 14 performs an operation of reading and repeatedly outputting a predetermined repelling sound stored in advance, for example, a mosquito feather sound, when a warning setting operation for sliding from the illustrated OFF position to the upper ON position is performed. Make it.

  The display unit 18 uses, for example, an LED, and when the output of the repelling sound is started by the warning setting operation of the warning setting switch 14, the display unit 18 lights up or blinks to display the operation state. The alarm switch 20 is, for example, a push button switch. When an alarm operation is performed by pressing the button, a predetermined alarm sound is output at a predetermined large volume, for example, a volume of 85 dB or more, and a function as a security buzzer is realized.

  The acoustic hole 16 has a built-in speaker so that a repelling sound and an alarm sound can be output. The strap attachment portion 22 can be suspended from a user's bag or the like by attaching a strap (string).

[Functional configuration of security alarm device]
FIG. 2 is a block diagram showing an outline of the functional configuration of the security alarm device 10 according to the present invention. In FIG. 2, the security alarm device 10 includes a control unit 24, a warning setting switch 14, a display unit 18, an alarm switch 20, a storage unit 26, a reproduction unit 28, and a speaker 30, and operates with a battery power source (not shown).

  The control unit 24 is a function realized by executing a program, for example. As the hardware, a CPU, a memory, a computer circuit having various input / output ports, and the like are used. Note that the storage unit 30 is realized by a partial function of a memory provided as hardware.

  The storage unit 26 stores a predetermined repelling sound in advance. In the present embodiment, the repelling sound stored in the storage unit 26 stores, for example, a mosquito feather sound that causes a strong repelling feeling when a person hears it. As shown in FIG. 3, for example, as shown in FIG. 3, three different signal patterns A, B, and C are prepared and stored as mosquito feather sounds stored in the storage unit 26 as repelling sounds.

  FIG. 3 shows signal patterns A to C of one phrase mosquito feathers reproduced at one phrase time T0 based on reading from the storage unit 26. Mosquito feather sounds are known to change in the range of about 300 Hz to 600 Hz, and when a person hears the mosquito feather sounds, they do not be attacked by the mosquitoes and thus take action to unconsciously drive them away. In addition, even if mosquitoes can hear the wings, they can hardly catch their appearance, and when stabbed, they cause a strong itching due to an allergic reaction, so most people have a strong repellent feeling.

  The signal pattern A represents a state in which the wing noise increases as the mosquito approaches, and the wing sound decreases as the mosquito approaches and then moves away. Signal pattern B shows that the mosquitoes approached and suddenly stopped after the wing noise reached its maximum, and this caused the mosquitoes to stop moving on people, and then the mosquitoes move away and stop. ing. Further, the signal pattern C represents a state in which the mosquito approaches once after approaching, and then approaches again and approaches further.

  The one-phrase time T0 of the signal patterns A to C of such mosquito feather sounds is set to a certain time in the range of, for example, T0 = about 5 to 10 seconds.

  The waveform of the signal patterns A to C may be a signal pattern recorded by bringing a small microphone close to an actual mosquito, or a signal pattern created artificially using a synthesizer or the like. .

  In addition, the storage of the mosquito feather sound signal patterns A to C in the storage unit 26 converts each analog signal into a digital signal by AD conversion and stores it.

  Referring to FIG. 2 again, the reproducing unit 28 includes an audio amplifier capable of controlling the gain, and the repelling sound signal E1 read from the storage unit 26 by the control unit 24 and converted into an analog signal is set by the gain control signal E2. Amplification is performed based on the gain, and output to the speaker 30 for reproduction.

  The volume of the mosquito feather sound reproduced from the speaker 30 by the repelling sound signal from the reproduction unit 28 may be a volume that can be heard when approaching the user carrying the crime prevention alarm device 10, and the volume is increased too much. Since it is unnatural as a mosquito's feather sound, for example, it is set to a volume that can be heard when approaching a range of about 2 to 3 meters.

  The gain of the playback unit 28 is controlled so that the volume is, for example, 85 dB or more when an alarm operation by the alarm switch 20 is detected by the control unit 24.

  The control unit 24 performs security warning control and security warning control.

(Security and security control)
When the control unit 24 detects acceptance of a warning setting operation by turning on the warning setting switch 14, the control unit 24 sequentially reads, for example, the mosquito feather sound signal patterns A to C stored in the storage unit 26 in advance. Then, after outputting the wing sound of one phrase based on the read signal pattern, security warning control is performed to reproduce and output the wing sound of the next one phrase after a predetermined pause time.

  In this case, the control unit 24 performs control to repeatedly output the mosquito feather sound as a repellent sound while changing the reproduction volume and the pause time at random.

  FIG. 4 is a time chart showing the security alert control performed by randomly changing the playback volume and pause time performed by the control unit 24. FIG. 4 (A) shows the playback volume, and FIG. 4 (B) shows the playback volume. And shows a pause.

  As shown in FIG. 4A, the control unit 24 controls the gain of the playback unit 28 so that the playback volume is changed to three levels, for example, large, medium, and small, and the order of changing the playback volume is as follows. For example, a random pattern such as “Large / Medium / Small / Medium / Medium” shown in the figure is changed and this random pattern is repeated. Note that the control unit 24 may change the reproduction volume in a predetermined order and repeat this.

  Further, as shown in FIG. 4B, the control unit 24 reads, for example, “A · B · C · B · A” as the order of reading the signal patterns A to C of FIG. 3 stored in the storage unit 26. The random pattern is controlled randomly so that this random pattern is repeated. Note that the control unit 24 may change the patterns A to C in this order, and control to repeat this.

  Further, the control unit 24 randomly changes the pause time when the signal patterns A to C are reproduced at random as different pause times as indicated by pause times T1 to T4 in FIG. It is controlled to repeat. Note that the control unit 24 may control the predetermined pause time without changing the pause time.

  In this way, the volume and signal pattern of the mosquito's feather sound that is played as a repellent sound is randomly changed so that it feels as natural as possible as a mosquito's feather sound. The illusion is that you are in the middle of your life so that you can divert your attention and lose the timing and energy to attack.

(Security alarm control)
When the control unit 24 detects acceptance of a security alarm operation by the alarm switch 20, the control unit 24 reads a security alarm sound stored in advance in the storage unit 26, controls the gain of the reproduction unit 28 to a predetermined gain, and controls the speaker 30. Control to output a security alarm sound at a loud volume of 85 dB or more.

  This security alarm control is similar to a conventional buzzer buzzer when a suspicious person's behavior is not suppressed and is attacked or attacked despite repeated output of repellent sounds such as mosquito feathers. For example, a crime prevention alarm sound with a large volume is output by a push button operation, and the threat to the suspicious person and the occurrence of an abnormality are notified to the surrounding people.

(Operation of security alarm device)
The operation of the security alarm device 10 according to the present embodiment is as follows.

  The security alarm device 10 of the present embodiment is always carried by a user, for example, a woman by wearing a strap string on her bag or the like.

  For example, when a female user who carries the security alarm device 10 comes home at night, he approaches a place where there is almost no traffic, and if a person comes from behind, the alarm setting switch of the security alarm device 10 14 is turned on and, for example, a mosquito feather sound is output as a repelling sound in a different pattern with a random pause.

  Thus, when a suspicious person approaches a female user in a state where a mosquito feather sound is repeatedly output as a repelling sound from the security alarm device 10 carried by the female user, for example, about 2 to 3 meters. When you reach the range, you will hear the sound of mosquitoes, and you will be deprived of attention to try to get rid of the mosquitoes, and you will be able to lose the timing and motivation to attack.

  Further, even if a mosquito feather sound is repeatedly emitted from the crime prevention alarm device 10 as a repelling sound, if a suspicious person who hesitates to act once tries to attack or strikes, the alarm switch 20 of the crime prevention alarm device 10 is used. By operating the, the security alarm can be output at a loud volume, threatening the suspicious person, and notifying people in the vicinity of the occurrence of an emergency.
