Abstract

A sound information device consisting of a housing, a power source, a control unit connected to a memory unit, a play button and an electro-acoustic transducer, characterized in that a pairing unit is connected to the circuit between the control unit and the electro-acoustic transducer, the output of which is connected to an electrical connector for connecting a special equipment.

Description

The utility model relates to the field of means of providing orientation facilitation, obtaining information by persons with various diseases of the sensory organs, in particular, to audio information transmission devices. It is preferable to use a utility model in the field of rehabilitation of people with hearing impairments, in particular hearing impairment.

Well-known audio information devices are designed to acoustically inform an unlimited number of people of various kinds of information, for example, about the location, purpose of infrastructure, and the sequence diagram.

A device is known tactile-sound mnemonic circuit described in patent document No. 135173 (application dated July 31, 2013 published on November 27, 2013). One of the functions of this device is the scoring of various information to a user suffering from a disease of the organs of vision.

The scoring of information is provided by the power supply available in the device, the memory unit, the digital-to-analog converter, the button, and the electro-acoustic converter. The digital-to-analog converter is connected to a memory unit, a button, and an electro-acoustic converter. A power supply unit, a memory unit and a digital-to-analog converter are located in the case, a button is placed to ensure its accessibility from the outside of the case, and an electro-acoustic converter is placed to allow listening to the information it emits from the outside of the case.

The operation of the device is as follows. If it is necessary to obtain information or additional information not reflected in text form, the user clicks on the button. A signal corresponding to the specific information contained in the memory unit, which is reproduced by the electro-acoustic transducer, is supplied to the digital-to-analog converter.

The disadvantage of this device is that the audio transmission of information is carried out in a single way - through an electro-acoustic transducer.

A well-known speaking information plate is described in patent document No. 135912 (application dated 08/06/2013 published on 12/27/2013).

The main purpose of the device described in the patent document is the storage and reproduction of sound information of various nature, for example, information about the purpose of the room, work schedule, etc.

The device consists of a housing, a power source, a control unit connected to a memory unit, a microphone, a microphone activation button, a play button, an electro-acoustic transducer.

The operation of the device is as follows.

The necessary information recorded by means of a microphone is stored in a memory unit. When you click on the play button, information through the control unit is extracted from the memory unit, converted into an analog signal and voiced by an electro-acoustic transducer.

This device is selected as a prototype.

The disadvantage of the prototype is its limited effectiveness in transmitting audio information. So, the prototype is not able to transmit acoustic information to people suffering from diseases of the hearing organs, causing its partial loss or weakening. The device does not contain elements that allow for the delivery of sound information to persons with hearing impairment. Since the device is located in a public place, the level of external noise does not allow people with hearing impairment to perceive sound information reproduced by the device, and an increase in the volume level of the device’s speaker is not structurally provided and may be unacceptable due to restrictions on the volume level in public places. The device is also deprived of the technical ability to connect to special equipment to ensure the delivery of sound information by other methods than playback through a sound emitter, for example, with an amplifier for induction systems for the hearing impaired.

The task to which the claimed utility model is directed is to provide the technical feasibility of interfacing an audio information device with special equipment, for example, an amplifier for induction systems for the hearing impaired.

The technical result of the utility model is to increase the efficiency of the sound information device by creating the technical ability to deliver sound information to the hearing impaired in a different way than through reproduction by means of a sound emitter.

A sound information device consisting of a housing, a power source, a control unit connected to a memory unit, a play button and an electro-acoustic transducer, characterized in that a pairing unit is connected to the circuit between the control unit and the electro-acoustic transducer, the output of which is connected to an electrical connector for connecting special equipment .

As a control unit, any microprocessor with an integrated digital-to-analog converter can be used; in a number of technical implementations, a digital-to-analog converter can be used as a control unit.

As a power source, a rechargeable battery or mains power through a transformation device can be used.

The memory block can be made as a separate element, or integrated into a microprocessor.

The role of the interface unit may be, for example, a resistor divider.

Any type of electrical connection suitable for connecting special equipment can be used as an electrical connector for connecting special equipment.

As special equipment, for example, an induction loop signal amplifier or other device can be used.

The utility model is implemented as follows.

When a hearing-impaired user presses a play button, the information previously recorded in the memory unit is transferred through the control unit to the circuit between the control unit and the electro-acoustic transducer in the form of a signal. Through the interface unit, the signal is fed to an electrical connector for connecting special equipment.

The signal coming through the electrical connector for connecting special equipment is processed by the connected special equipment, for example, an induction loop amplifier. After processing, the signal through the induction loop is fed to the user's hearing instrument and is voiced individually, without interference and with a given volume and quality.
