Abstract

The utility model discloses a theft-proof bag with a whistling device, which is the improvement of a bag for putting money and objects. A bag body tailored by flexible material is arranged in a bag or a pocket. A thin insulating lead wire or a ribbon-shaped metallic foil in a net shape is distributed on the surface in the bag body. The both ends of the lead wire are connected with the switch of a bag mouth. A circuit box which can whistle is fixed on the surface in the bag body, and the lead wire of the circuit box is switched on the thin insulating lead wire or the ribbon-shaped metal foil. The utility model has the advantages of simple structure and good theft-proof performance; only the theft-proof bag with a whistling device is opened or is cut broken, and the theft-proof bag with a whistling device can whistle.

Description

Theft-proof purse with whistling device

The utility model relates to a kind of architecture advances of putting money, thing bag, to some circuits and electronic devices and components be set in the bag, when putting money, can sending music when the thing bag is opened, increase delight of life, or send other sound, reminds people vigilance prevents that money, thing from being stolen, and is a kind of sounding Theft-proof purse specifically.

Be placed with money and goods in the general pocket or in the bag, handbag, the people relatively during the walking of crowded places,, perhaps stolen and do not realized, cause economic loss and mental burden sometimes because careless sack is opened, and money and goods is lost.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of sounding Theft-proof purse of putting money, thing, and when sack was opened, the reminds people vigilance of promptly can sounding prevented that money and goods from losing.

The present utility model purpose is realized by following technical scheme: the bag that this sounding Theft-proof purse is seamed into by flexible material is made or is bonded in the bag or in the pocket, there are a thin insulated conductor or a ribbon metal forming to be mesh cloth purseful body inside surface, the lead two ends are connected with the sack switch, the circuit box of energy sounding is fixed on the bag inside surface, and its extension line is connected with insulation thin wire or belt metal foil.

The sack switch is following any structure: the folding of sack can be adopted press-button type or zip mode or magnet-type or the sticking formula of nylon, and netted circuit two ends are connected with the sheet metal that is located at the sack both sides.According to the length of sack, the number of decision sheet metal, when sack is longer, can more sheet metals, the formed space of distance wants littler between the two metal sheets, and hand can not be stretched.If hand one puts in sack, will strut the sheet metal that contacts with each other, circuit is disconnected, the circuit box of energy sounding will be sounded people are given a warning, and points out the money and goods in the sounding Theft-proof purse.

The power supply that circuit box is made of button cell, on-off circuit, sound generating circuit, and the plastic casing that foregoing circuit is installed form.

On-off circuit is made up of cmos phase inverter 3, protective resistance 2, the positive charge resistance 1 of releasing.When hand touches two sheet metals of sack correspondence simultaneously, release through 1 through the micro-positive charge of receiving and distributing, be equivalent to off state, band helps the sounding component 6 of the operatic tunes to sound.

Sound generating circuit helps the piezo-electric ceramic sounding element 6 of the operatic tunes to form by audio manifold block 4, band.In order to enlarge the sound of emitting, power amplifier tube 5 of adjunction in circuit according to circumstances.The sound of recording in the audio manifold block can be music or warning language or alarm song, likes selecting different acoustic for use according to people's difference.

Its principle of work is: when sack is opened or bag when being cut; circuit disconnects; the input low-voltage through protective resistance Z behind cmos phase inverter 3; by phase inverter 3 output HIGH voltages to audio ic 4; audio ic 4 sends different electrical signals and directly or through power amplifier tube 5 back input tapes helps the piezo-electric ceramic sounding element 6 of the operatic tunes under action of high voltage, electric signal is converted into vibration sounds.When sack is closed, closing of circuit, cmos phase inverter input high voltage, output LOW voltage, audio ic does not signal, and loudspeaker is sounding not.

The utility model has the advantages that simple in structurely, ingenious, as long as cut or open the sounding Theft-proof purse, perhaps hand reaches and will send the alternative sounds of selecting according to people in the middle of the sack, and existing delight of life has the anti-function of stealing again.Owing to adopted piezoelectric ceramic loudspeaker, had diamagneticization destruction.Be the sounding Theft-proof purses of a kind of making and settlement that are suitable for applying in bag or in the pocket.

Embodiment of accompanying drawings.

Fig. 1 is a sounding Theft-proof purse stretch-out view,

Fig. 2 is the circuit logic diagram that the sounding Theft-proof purse has power amplifier tube,

Fig. 3 is the circuit diagram that the sounding Theft-proof purse has power amplifier tube,

Fig. 4 is the circuit logic diagram that the sounding Theft-proof purse does not have power amplifier tube,

Bag 10 is that weaving cloth is made, and its two sides and bottom surface can be made in the bag or in the pocket, and insulation thin wire 12 reticulates the inside surface that is covered with bag 10, sack has 3 pairs of snap-fasteners 11, is the metal snap-fastener, and itself has electric action, alternative sheet metal couples together with insulation thin wire 12.Circuit box 9 is fixed in the bag 10, and the extension line of circuit box is connected with the insulation thin wire.The power supply of being made up of the miniature button cell 7 of 3 joint 1.5V in the circuit box also has on-off circuit and sound generating circuit.On-off circuit comprises the positive charge resistance 1 of releasing, and its resistance value is 22K Ω; Protective resistance 2 its resistance values are 100K Ω; Cmos phase inverter 3, its model are Cc4069.Sound generating circuit comprises audio manifold block 4, model be in the CW9400 series any; Power amplification triode 5, model are 3DG6; Band helps the piezo-electric ceramic sounding element 6 of the operatic tunes, and model is HTD27A-1, φ 27mm.In sounding Theft-proof purse bottom 2 snap-fasteners are arranged, by in bag bottom or two of pocket inner bottom part by buckling, between bag bottom or two snap-fasteners of pocket inner bottom part, there is lead to connect, when the sounding Theft-proof purse is stolen when being removed from pocket or bag, circuit cuts off, piezoelectric ceramics block can sound the alarm, and calls people's attention.When producing in enormous quantities, the positive charge resistance 1 of releasing, protective resistance 2, phase inverter 3, audio manifold block 4 can integrate reduced volume.

Audio manifold block 4 is selected the KK-41C type for use among Fig. 4.
