Description

Digital sound device

The proposed utility model relates to sound reproducing devices and can be used in sound advertising, burglar alarms, sound (including musical) toys for recording, storing and playing various kinds of sound information (voice messages, alarms, fragments of musical works, etc.). The device provides automatic playback of information when people appear near it. The main area of use of the proposed utility model is the sound advertising of goods in various retail outlets.

Currently, sound-reproducing devices for advertising and burglar alarms are being developed quite intensively, to a much lesser extent (according to a comparison of the number of patent documents) for musical games.

Known sound reproducing devices for recording, storing and automatically playing back audio information and used in burglar alarms (RuC | 2153567, RuC | 214421 |, RuA, 1611129, RuCi2099789, RuCi2057368, RuCi2029373, RuC, 2006949, RuC | 2006950, etc.) . As a rule, these devices are characterized by a complex and highly sensitive system for detecting the violation of the border of protected objects when using fairly primitive audio signals. Since these devices are performed without the possibility of recording audio information in the form of voice messages, as well as without the possibility of a constant change of these messages, their use for advertising purposes is impractical. In addition, these devices are generally not

portable and autonomous and provide a complex communication system with various parts of the protected objects, which also limits their scope.

Known sound reproducing devices for recording, storing and playing back audio information and used in sound advertising (see, for example, RuMi28406, RuMi26675, RuCi2136058, RuC22199785, RuCi2145736, RuCi2101780). In these devices, mainly for the transmission of information, a connection is made to the channels of radio and television broadcasting, preliminary recording of information on a tape recorder. Since the proposed utility model is a digital portable stand-alone device, which is a hardware-software complex, devices similar to those described, for example, in patents of the Russian Federation No. 2197165, 2161822, 2145736 are closer to it.

In the patent of the Russian Federation No. 2197165, drinking utensils equipped with a special vibration sensor and configured to transmit a signal via the quick-wire communication channels to start the actuator have the function of sound advertising, while the vibration sensor is triggered by the collision of dishes (glasses, glasses, etc.)

The RF patent JV22161822 describes a device for sound advertising and sound signaling, in which the informing functions are attached to the stands for pictures and vessels, and the reproduction of a pre-recorded sound message begins when the device is lifted from the table (the key connecting the input of the playback switch to the first source bus is closed voltage).

The RF patent. No. 2145736 describes a sound-reproducing label made using digital technologies, which is attached to the advertised product and reproduces a pre-recorded sound advertising message when a special button is pressed, or (if the label is made in the form of a booklet) - when the booklet label is opened.

The disadvantages of the above three devices are:

1. Lack of autonomy in the work (sound reproducing devices are inextricably linked with the advertised goods);

2. The need to supply a sound reproducing device for each unit of goods;

3. The inability to reprogram devices to change advertising messages (in whole or in part).

4. The need for mandatory contact with the advertised product.

For the prototype of the proposed device, a digital sound reproducing device is selected, which includes a constantly reprogrammable memory unit, a unit for reproducing audio information, and an automatic start unit. (Application for invention of the Russian Federation No. 2002108503/09. Advertising method and device for its implementation. IPC G09F25 / 00. Published on March 10, 2003). The prototype device is an electronic reproducing audio device with recorded advertising information, which is placed in special “pockets on the packaging of the goods. The power switch of the device is connected to the lid of the package and (or) the packaged product, and this happens when the package with the product is opened and / or the product is removed from the package, and when the package with the product is opened and (or) the product is removed from the package, the advertising information is reproduced starts from the beginning.

A prerequisite (and a common feature with the proposed utility model) is a constantly reprogrammable memory unit, which provides repeated reproduction of advertising information. However, at the same time, as well as the analogues described above, the prototype device is characterized by such disadvantages as: lack of autonomy in work and inextricable connection with the advertised product, the need to supply sound-reproducing devices to each

units of goods, the need for mandatory contact of the buyer with the advertised product, as well as the inability to control the sound volume, sequence and speed of playback, and other indicators.

The objective of the proposed utility model is to create the possibility of autonomous operation of the device without communication in the advertised product, eliminating the need to supply sound units of each unit of the advertised product, the ability to play sound information without any special actions by customers (opening the product, pressing a special button, lifting the product and etc.), creating the ability to constantly change the recorded information (partially or completely). In addition, the objective of the proposed utility model is the creation of the ability to control software settings depending on the external conditions and wishes of the customer, setting a specific sequence of information playback, the duration of pauses between device operations, adjusting the sound volume, the ability to force playback to start.

The task is achieved in that the device is portable and autonomous, the automatic start-up unit is made in the form of a photodetector selected from the group: photoresistor, photodiode, infrared radiation receiver; the audio information playback unit is made in the form of a loudspeaker, the device is additionally equipped with a microprocessor in the form of a high-speed reprogrammable microcontroller with built-in internal memory, as well as a low-frequency amplifier equipped with high-pass and low-pass filters, an interface port, a sound volume control and buttons for controlling the device operation modes, while the microprocessor and the memory block are interconnected by an interface bus, the outputs of the automatic start block and

buttons for controlling the operation modes of the device are connected to the microprocessor, the input of the low-frequency amplifier is connected to the microprocessor, and its output is connected to the input of the speaker.

In figure 1. presents a possible implementation of the appearance of the proposed device (Fig 1a is a front view, Fig. 16 is a rear view). In figure 2. presents a structural diagram of the proposed device. Structurally, the device of FIG. 1 comprises a housing 1 on one of the outer sides of which a speaker shield 2 and control elements are located: an on / off button for the device 3, a volume control 4, buttons for controlling the operation modes of the device 5.6, a window for the automatic start device 7 .On the other side of the module, there is an interface connector 8 for connecting external devices (computer, printer, similar to the device’s central memory). In Fig.2, the device contains a microprocessor (MPU) 9 and a memory unit (EEPROM) 10 which are interconnected by an interface bus 11, which can be either serial or parallel, depending on the type of memory used). As a microprocessor, a high-speed FLASH microcontroller from Microchip can be used (for example, P1C18F452 technical documentation DS3956A from Microchip Technology 1 psofoga1eё, USA). Using this type of microcontroller allows you to flexibly control devices connected to the microprocessor using the developed software and the standard set of microcontrollers of the microcontroller. As a memory module, flash memory with Atmel serial interface can be used (for example AT45DB041B technical documentation Rev. 193 8FDFLSH-10/02).

an automatic start-up device 12 and control and adjustment buttons 5 are connected to the microprocessor. A photodetector selected from the group: photoresistor, photodiode, infrared radiation receiver can be used as an automatic start device.

The output from the microprocessor is transmitted to the input of the low-frequency amplifier 13, which is equipped with a high-pass and low-pass filter 14.

Reprogramming the contents of the memory module, downloading software is done through the interface port 15 and bus 17.

The proposed device works as follows: When the power is turned on, the device is reset and set. The automatic start device, made in a specific implementation on a photocell, registers the value of illumination at the installation site of the device and transfers this data to the microprocessor. When a buyer walks past counters, display cases, trading trays, tables (equipped with this device), the automatic start-up device detects a change (by using a photocell or IR sensor, it detects a change in environment) and transmits a signal to the microprocessor, which starts the data exchange firmware with the memory module. Data from the memory is transferred to the microprocessor, and then the useful signal is fed to the low-frequency amplifier, and the buyer hears the reproduced information through the loudspeaker.

The sensitivity of the automatic start device and the pause between the operation of the device are regulated by software settings depending on the external conditions and the wishes of the customer.

Using a set of control buttons, you can set a specific sequence of information playback, as well as force playback to start.

in retail outlets, the proposed device can simultaneously perform the functions of sound advertising and sound signaling: the inclusion of a sound reproducing device when the buyer approaches, at the same time informs the buyer about the product and signals the seller about the location of the buyer or that the buyer has entered the premises (if the device is located at the entrance).

It is possible to use the device only as a security alarm. In this case, the sound information recorded and stored in the device should be an alarm signal, and the device should be located next to the protected goods (in retail outlets), or next to the exhibited sample (at exhibitions, shop windows), or (when protecting premises) several devices should be located in different parts of the premises.

It is possible to use the proposed device as an integral part of sound (including musical) toys, or as an independent sound toy.
