A group of useful models relates to the field of digital recording, namely, devices for recording and reproducing MP3 files, and is intended for recording and reproducing stereo speech of “talking books”, “sound books”, reproducing text files, as well as using as an FM radio receiver.

Talking books and sound books reproduce digital phonograms and are intended primarily for people with an inability to read, and especially for the blind and visually impaired.

In accordance with modern requirements, the cost of recording and reproducing phonograms should be the lowest. Recording and playback of phonograms should be carried out using technical means that are used by the whole population, while the condition must be met - the voice must be clear during reproduction. These tools should provide people with disabilities the ability to control the device.

One of the carriers of modern and promising digital phonograms is a flash card. Recording a talking book for the blind is in MP3 file format. The cheapest means of recording and playing MP3 files are MP3 players.

A device is known “Acoustic column” (patent for the invention of the Russian Federation No. 2086074, published July 27, 1997), comprising a housing, a loudspeaker with a diffuser installed in the housing, and a sound reflector mounted opposite the front surface of the diffuser, characterized in that the housing is made with an annular hole on the front wall and has a hemisphere-shaped partition, the loudspeaker is low-frequency and is installed along the edge of the diffuser in the opening of the partition wall, and the sound reflector has the shape of a hemisphere, the base of which is The swarm is fixed on the inner side of the front wall of the housing along the inner radius of its annular hole.

A disadvantage of the known technical solution is that the shape and design of the speaker system, in particular the speakers, are such that it has separate high-frequency, mid-frequency and low-frequency speakers to improve the quality of the audio signal, additional structural elements of the case are used to improve the quality of sound transmission through the speakers . This speaker system is not designed for portable dimensions of the reproducing device. The speaker systems of portable devices use a single speaker and usually do not have a case, which reduces the sound quality of reproduced information due to the small dynamic range, distortions at high volume levels, etc.

The problem to which the claimed technical solution is directed - the Acoustic Column, is to improve the quality of reproduction of audio information in the speaker system of a portable digital tifloplayer, since this device is intended primarily for people with visual impairments, for which listening to sound phonograms is one of the main sources of obtaining information. Therefore, the highest requirements are imposed on the quality of reproduction of sound information in portable devices used by the visually impaired.

The technical result consists in the development of a special design of the acoustic column of a digital tifloplayer, which provides improved quality of reproduction of audio information with portable dimensions of the device.

The utility model "Acoustic column" is illustrated by the following drawings:

Fig. 8 - Arrangement of acoustic elements in the case of a tifloplayer.

Figure 9 - Mounting of acoustic elements to the front panel of the tifloplayer case

Figure 10 - Location of speakers in acoustic elements

11 - Acoustic element assembly

Fig - The back of the acoustic element (cup)

Fig - The front part of the acoustic element (cap)

Fig. 14 - Speaker

The acoustic column consists of two small-sized acoustic elements (7), placed in the case of a tifloplayer (1) and rigidly fixed in it. The speaker housing serves simultaneously as a tifloplayer case.

Rigid fixing of the speakers in the case of the acoustic element provides clearer sound reproduction in the absence of noise caused by vibrational movements of the speaker in the device. In addition, the volume of air in the sealed enclosure of the acoustic element has damping properties. The installation and fixing of acoustic elements in the case of a Tifloplayer reduces the dispersion and enhances the effect of suppressing interference during the propagation of an audio signal, thereby providing the best performance for reproducing audio information with portable dimensions of the device.

The front and rear parts of the body of the acoustic element are fastened together using sealed adhesive joints located in the same plane.
