Japanese Unexamined Patent Publication No. 2013-126498

When voice guidance is performed in the luggage storage box as described above, it is common to incorporate a speaker in the operation panel. However, in this case, it was necessary to secure a large space on the back side of the operation panel in order to install the speaker.

On the other hand, it is conceivable to arrange a vibrating device on the back surface of the operation panel and vibrate the wall surface of the operating panel by the vibrating device to generate voice guidance. In this case, since the exciter is smaller than the speaker, it is easy to secure the installation space. However, if the vibration generated by the vibrating device is widely transmitted to the wall surface constituting the operation panel, an unnecessary vibration sound is added to the voice guidance, which may make the voice guidance difficult to hear.

An object of the present disclosure is to provide a luggage storage box capable of clearing the voice guidance generated by using a vibration exciter and making it easier for the user to hear.

The luggage storage box according to the present disclosure is a luggage storage box in which a vibrating device is attached to the back surface of a panel wall surface of an operation panel including an operation unit, and sound is generated by vibration transmission from the vibrating device to the panel wall surface. The voice data transmitted to the exciter is a signal from which a predetermined low frequency band has been removed.

According to the luggage storage box according to the present disclosure, it is possible to clear the voice guidance generated by using the shaker and make it easier for the user to hear.

It is an overall perspective view of the luggage storage box which is one Embodiment. It is a figure which shows the back surface of the operation panel. It is the figure which looked at the exciter attached to the back surface of the operation panel from the vertical direction. FIG. 3 is a cross-sectional view taken along the line AA in FIG. It is a side view which shows the stud bolt enlarged. It is a functional block diagram which shows the structure which the audio signal is applied to a vibration exciter. It is a figure which shows the equal loudness curve.

Further, two lock levers 19 are rotatably provided on the back surface of the operation panel 14. These lock levers 19 can be rotated by inserting a key from the front side (front side) of the luggage storage box 10. When the lock lever 19 is rotated to a position disengaged from an engaging portion (not shown) provided on the frame portion 18, the panel door 15 constituting the operation panel 14 can be opened. On the other hand, when the lock lever 19 is rotated to a position where it engages with the engaging portion provided on the frame portion 18, the panel door 15 constituting the operation panel 14 is locked in a closed state. The key for opening the panel door 15 of the operation panel 14 is possessed by the manager who manages the luggage storage box 10.

The display unit 20 is installed at substantially the center position in the vertical direction and the width direction on the operation panel 14. For the display unit 20, for example, a touch panel type liquid crystal display device can be preferably used. The display unit 20 can display the procedure of how to use the luggage storage box 10 to the user with images or characters. Further, the user can input information such as temporary deposit, delivery, and receipt by touching the icon or the like displayed on the display unit 20.

The printer 22 has a function of printing out a piece of paper such as a receipt or a receipt to the user. This piece of paper may be printed with the date and time of use of the luggage storage box 10, the purpose of use (for example, temporary deposit, delivery, etc.), the usage fee, and the like. Further, bar code information indicating the locker box specific information in which the cargo is deposited, the deposit date and time information, and the like may be printed on a piece of paper for the user used for the purpose of temporary deposit of the cargo. By reading the barcode printed on this piece of paper with a barcode reader described later, the usage fee can be calculated based on the locker box size used, the usage time (or the usage period), and the like.

The camera 24 has a function of capturing an image of a user who operates the operation panel 14 from the viewpoint of crime prevention. It is preferable that the captured image is stored in the storage unit for a predetermined period of time. This storage unit can be provided in a control unit arranged inside or outside the luggage storage box 10, which will be described later. The camera 24 can be configured to start the shooting operation when the touch operation on the display unit 20 is detected, and stop the shooting after the state in which the touch operation on the display unit 20 is not performed continues for a predetermined time.

The payment terminal 26 has a function of allowing a user to pay a baggage delivery fee, a baggage purchase price, a baggage storage box 10 usage fee, and the like by contacting an IC card capable of electronic payment. As the readable IC card, for example, an IC card that can be used for paying a train fare can be used.

Insert the mobile phone into the department. As a result, when the information read by the barcode reader 28 matches the consignee information, the opening / closing door of the locker box in which the luggage addressed to the user is stored is unlocked. As a result, the user can receive the baggage addressed to him / her.

In the operation panel 14, the exciter 30 is installed on the back surface of the panel door 15. The exciter 30 has a function of transmitting vibration to the panel wall surface of the panel door 15 and thereby generating voice guidance on the front surface side (or front side) of the operation panel 14. In the present embodiment, the exciter 30 is arranged on the back surface of the panel door 15 and next to the display unit 20. Further, it is preferable that the exciter 30 is arranged at a position near the edge portion of the panel wall surface constituting the panel door 15.

FIG. 3 is a view of the exciter 30 attached to the back surface of the operation panel 14 as viewed from above and below. FIG. 4 is a cross-sectional view taken along the line AA in FIG. Further, FIG. 5 is an enlarged side view showing the stud bolt 44.

As shown in FIGS. 3 and 4, the exciter 30 is attached to a mounting portion 40 provided on the back surface of the panel wall surface 15a constituting the panel door 15. The mounting portion 40 is composed of a vibration transmission plate 42 to which the exciter 30 is mounted, and a stud bolt 44 and a nut 46 for fixing the vibration transmission plate 42 to the back surface of the panel wall surface 15a. Further, a sheet 48 may be provided between the vibration transmission plate 42 and the panel wall surface 15a. When the seat 48 is provided, the seat 48 is also a member constituting the mounting portion 40.

The vibration transmission plate 42 is formed of, for example, a metal plate. The vibration transmission plate 42 is preferably formed of a metal plate having a thickness thicker than that of the panel wall surface 15a. By forming the vibration transmission plate 42 from the thick metal plate in this way, the rigidity of the portion of the panel wall surface 15a to which the vibration transmission plate 42 is fixed increases. As a result, when vibration is transmitted from the vibrating device 30 to the panel wall surface 15a via the vibration transmission plate 42, the area of the region where the panel wall surface 15a vibrates can be limited. As a result, it is possible to suppress unnecessary vibration sound from being superimposed on the voice guidance generated by the vibration of the panel wall surface 15a. Here, the unnecessary vibration sound is a wide panel area including not only the panel area of the mounting portion 40 to which the exciter 30 is mounted but also other panel areas to which the printer 22, the camera 24, etc. are mounted. It is a vibration sound generated by the vibration of the camera, and is also called a chattering sound.

The vibrating device 30 is fixed to the vibration transmission plate 42 by, for example, a countersunk screw (not shown). The threaded portion of the countersunk screw is inserted into the through hole of the vibration transmission plate 42 and screwed into the female threaded portion of the exciter 30. Further, the head of the countersunk screw is housed in a truncated cone-shaped counterbore hole formed in the vibration transmission plate 42.

The vibration transmission plate 42 is fixed by a nut 46 screwed into a stud bolt 44 erected on the back surface of the panel wall surface 15a. Specifically, as shown in FIG. 4, two stud bolts 44 are erected on the back surface of the panel wall surface 15a. As shown in FIG. 5, the stud bolt 44 has a shaft-shaped threaded portion 44a, a flange portion 44b provided at the end of the threaded portion 44a, and a protrusion 44c projecting from the center of the end surface of the flange portion 44b. Have. The stud bolt 44 is positioned with the protrusion 44c fitted in the recess formed in the panel wall surface 15a, and the flange portions 44b are welded and fixed to the panel wall surface 15a at a plurality of places.

The vibration transmission plate 42 is a long metal plate extending in the vertical direction, and through holes are formed in the upper end portion and the lower end portion, respectively. These through holes have a larger diameter than the flange portion 44b of the stud bolt 44 and do not interfere with the weld overlay portion (or the weld whiskers portion) that may be formed so as to project around the flange portion 44b. It is preferably formed to the diameter of. By being formed in such a size, the vibration transmission plate 42 can be fixed in close contact with the panel wall surface 15a, and vibration transmission from the vibration exciter 30 can be efficiently performed.

The two stud bolts 44 erected on the panel wall surface 15a as described above are inserted into the through holes at the upper end and the lower end, and the vibration transmission plate 42 to which the exciter 30 is fixed is assembled. Then, the nut 46 is screwed into the stat bolt 44 and tightened. As a result, the exciter 30 is attached to the panel wall surface 15a via the vibration transmission plate 42.

At this time, the sheet 48 may be interposed between the vibration transmission plate 42 and the panel wall surface 15a. The sheet 48 is made of, for example, a non-woven fabric, an adhesive tape, or the like. The thickness of the sheet 48 is preferably in the range of 0.1 to 0.5 mm. If it is thinner than 0.1 mm, it becomes difficult to bring them into close contact with each other while eliminating the surface irregularities of the vibration transmission plate 42 and the panel wall surface 15a. On the other hand, if it is thicker than 0.5 mm, the vibration of the exciter 30 is absorbed by the sheet 48. This is because the efficiency of vibration transmission to the panel wall surface 15a is reduced.

Referring to FIG. 3 again, the exciter 30 is arranged in the vicinity of the widthwise edge portion 15b of the panel door 15. In the present embodiment, a bent portion 15c is formed at the edge portion 15b of the panel door 15. The bent portion 15c is a width direction that is bent along the depth direction Y at a right angle from the panel wall surface 15a and a width direction that is further bent at a right angle from the end of the depth direction wall portion 15c1. Includes wall portion 15c2. By forming the bent portion 15c on the edge portion 15b of the panel wall surface 15a in this way, the rigidity of the panel wall surface 15a in the vicinity of the edge portion 15b is increased. Therefore, when vibration is transmitted from the vibrating device 30 to the panel wall surface 15a via the vibration transmission plate 42, the area of the region where the panel wall surface 15a vibrates can be limited. As a result, the amplitude of the panel wall surface 15a can be reduced. As a result, it is possible to suppress unnecessary vibration sound from being superimposed on the voice guidance generated by the vibration of the panel wall surface 15a.

In the present embodiment, an example in which the bent portion 15c formed on the edge portion 15b of the panel wall surface 15a includes the depth direction wall portion 15c1 and the width direction wall portion 15c2 has been described, but the present invention is not limited thereto. The bent portion may be composed of only the wall portion in the depth direction. Further, the bending angle of the bent portion is not limited to a substantially right angle, and may be set to an acute angle or an obtuse angle other than the right angle.

FIG. 6 is a functional block diagram showing a configuration in which a voice data signal is applied to the exciter 30. The exciter 30 is electrically connected to the control unit 34 via an amplifier 32. As the exciter 30 and the amplifier 32, any known configuration may be used.

The control unit 34 includes a CPU (Central Processing Unit) 34a, a storage unit 34b, and a voice data correction unit 34c. The control unit 34 is preferably configured by, for example, a microcomputer. Further, the control unit 34 may further include a sound pressure amplification unit 34d and a frequency specifying unit 34e. The functions of the sound pressure amplification unit 34d and the frequency specifying unit 34e will be described later.

The storage unit 34b stores a program or the like for managing the luggage storage box 10. The CPU 34a can read and execute a program or the like stored in the storage unit 34b. The control unit 34 may be provided on the back surface side of the operation panel 14 of the luggage storage box 10, or may be provided outside the luggage storage box 10 and connected via a communication line such as the Internet.

The control unit 34 is also electrically connected to the display unit 20, the printer 22, the payment terminal 26, and the bar code reader 28 via a signal line (not shown). The control unit 34 displays images and characters that guide the user's operation procedure. Further, the storage unit 34b stores voice data for a plurality of voice guidance for guiding the operation procedure, and the CPU 34a selects the voice data according to the operation procedure displayed on the display unit 20. Then, the selected voice data is output to the exciter 30 via the amplifier 32 after the predetermined low frequency band is removed (or cut) by the function of the voice data correction unit 34c described later. As a result, the vibrating device 30 vibrates, and the vibration is transmitted to the panel wall surface 15a constituting the panel door 15. As a result, the panel wall surface 15a functions as a diaphragm, and the voice guidance is radiated in front of the operation panel 14.

The voice data correction unit 34c in the control unit 34 has a function of removing or cutting a predetermined low frequency band included in the voice data. The audio data correction unit 34c is preferably configured by, for example, a bandpass filter, a lowpass filter, or the like. Here, the predetermined low frequency band is preferably 200 Hz or less. The reason will be described below.

Generally, the bandpass characteristics for telephone calls are defined as follows. The main component of the human voice is said to be in the frequency range of approximately 200 to 4000 Hz. Among them, the intermediate frequency is generally around 1000 Hz (or 1 kHz), and if the frequencies around this range can be covered to some extent, it is possible to realize sound quality that can distinguish the voice without covering all the frequencies. Further, this frequency band was determined from the experience that communication is sufficiently possible in the range of 300 to 3400 Hz. It has been well proven that this was appropriate even after many years of use. It is generally said that the human ear can hear the sound in the range of 2000 to 4000 Hz best.

FIG. 7 is a diagram showing an equal loudness curve. The equal loudness curve is internationally standardized as ISO226: 2003. The equal loudness curve is a contour line obtained by measuring the sound pressure level at which the same loudness (loudness by human hearing, noisy noise) is obtained when the frequency of the sound is changed. Further, in the graph of FIG. 7, the frequency (hertz (Hz)) is plotted on the horizontal axis and the sound pressure level (decibel (dB)) is plotted on the vertical axis, and 80, 60, and 40 are shown for a plurality of curves, respectively. The unit of each number of, 20 is "phon". Referring to the equal loudness curve, the lower the frequency band, the higher the sound pressure level. That is, a sound in a low frequency band cannot be heard as a sound of the same loudness unless the sound pressure level is high. In other words, the low frequency band is inaudible unless the sound pressure level is raised. Ultimately, the low frequency band is a sound that is almost inaudible to humans in the first place. Therefore, even if a predetermined low frequency band (for example, 200 Hz or less) is removed from the voice data, the audibility of the voice message is not deteriorated.

With reference to the bandpass characteristics of the above-mentioned telephone call, the frequency band below an appropriate frequency in the range of 100 Hz to 500 Hz was cut, and the highest cut frequency band in which the voice guidance was clearly heard was verified. As a result, it was determined that 5 out of 5 people heard the voice guidance that cut the low frequency band of 200 Hz or less most clearly. On the other hand, when the frequency band higher than 200 Hz (for example, 500 Hz or less) was cut, it was found that the bass portion of the voice guidance became difficult to hear and felt unnatural. Therefore, it was confirmed that the cut frequency band of the voice data is preferably 200 Hz or less.

In this way, in the control unit 34, the voice data from which the predetermined low frequency band has been removed by the voice data correction unit 34c is output to the amplifier 32, amplified by the amplifier 32, and applied to the exciter 30. As a result, the vibrating device 30 vibrates, and the vibration is transmitted to the panel wall surface 15a via the vibration transmission plate 42 and the seat 48, and as a result, the voice guidance is radiated forward.

At this time, when the audio data includes a low frequency region, the amplitude of the panel wall surface 15a becomes large due to resonance, and the operation unit configuration of the printer 22, the camera 24, etc. in another panel region away from the exciter 30 is configured. Even parts may vibrate and generate noise (or chattering noise). Then, the voice guidance may be difficult to hear due to the noise generated by the operation panel 15.

On the other hand, in the luggage storage box 10 of the present embodiment, the voice data transmitted to the vibration exciter 30 is a signal from which a predetermined low frequency band is removed, so that the generation of chattering sound on the panel wall surface 15a can be suppressed. As a result, the voice guidance can be easily heard by the user.

Next, a modified example of the luggage storage box 10 of the present embodiment will be described with reference to FIG. 6 again.

As described above, the control unit 34 may include a sound pressure amplification unit 34d. The sound pressure amplification unit 34d has a function of amplifying the sound pressure in the frequency band that overlaps with the frequency band of the noise of the surrounding environment in which the luggage storage box 10 is installed in the voice data applied to the exciter 30. As the frequency band amplified by the sound pressure amplification unit 34d, a frequency band stored in advance in the storage unit 34b by measuring the noise of the surrounding environment at the place where the luggage storage box 10 is set can be used.

In this way, if the sound pressure in the frequency band that overlaps with the frequency band of the noise in the surrounding environment is amplified to generate the voice guidance, the sound in the frequency band that is easily drowned out (or masked) by the noise in the surrounding environment is generated. The part can be made easier to hear. Further, when the sound pressure level of the entire voice guidance is amplified, the voice guidance itself generated from the luggage storage box becomes noise to the surroundings, but as in this case, the sound pressure level of a part of the voice guidance is amplified. If only, such an adverse effect can be prevented.

Further, although the frequency band amplified by the sound pressure amplification unit 34d has been described above as using the frequency band stored in advance in the storage unit 34b, the frequency band is not limited to this. The luggage storage box 10 may include a frequency specifying unit 34e in the control unit 34 and a microphone 36 for acquiring noise in the surrounding environment. It is preferable that the microphone 36 is arranged inside the operation panel 14 and close to the through hole 15d formed in the panel wall surface 15a in order to acquire the noise of the surrounding environment.

The noise of the ambient environment acquired by the microphone 36 is input to the control unit 34, and the frequency band of the noise of the ambient environment is specified by the function of the frequency specifying unit 34e. Using the frequency band specified here, the sound pressure amplification unit 34d of the control unit 34 amplifies the corresponding frequency band of the voice data. As a result, the same masking prevention effect as described above can be obtained. Further, in this case, it is possible to amplify the frequency band adapted to the noise level of the surrounding environment at that time, and there is an advantage that the adaptability to the change of the noise of the surrounding environment is improved.

The luggage storage box according to the present disclosure is not limited to the above-described embodiment and its modifications, and various changes and improvements can be made within the scope of the matters described in the claims of the present application. Of course there is.
