Description

Areas of technology

This useful model relates to the field of multimedia devices designed to work with sound, namely, devices designed for individual or group vocals in situations where it is necessary to isolate the user's voice from the environment, and the user from ambient noise. The utility model can be used to teach vocals and conduct rehearsals at home or during classes with a teacher, as well as for leisure and entertainment.

State of the art

The privacy mask is disclosed in the prior art, disclosed in the patent for utility model RU166740 (published on 12/10/2016, IPC H04M 1/05). Known technical solution consists directly of the mask itself, covering the lower part of the user's face, microphone and earphone for placement in the user's ear. The mask is made of an elastic material, which, when put on the face of the user, takes the form in accordance with the configuration of his face, has a bezel from the sealant, providing a comfortable fit to the skin. Sound-absorbing material can be used to make the mask. Additionally, the mask contains an exhalation valve, temples and a microphone. A clip for attaching a headphone is installed on one of the arms. The microphone is installed on the inside of the mask, in the mouth. The well-known privacy mask can be used with a cell or landline phone. Connection can be made using Bluetooth technology.

The design flaws of the known device are due to its purpose. Thus, the known device is intended, first of all, to ensure the confidentiality of negotiations, i.e. isolating the user's voice from the external environment. Vocal lessons require more intense breathing, which can be hampered by the fact that the mask is adjacent to the face area both around the mouth and nose of the user. Placing the nose inside the mask also makes vocals uncomfortable, and leads to distortion of the user's voice. Another disadvantage of the known device is the type of earphone used in it, which does not completely isolate the user from ambient noise. And given the fact that the known device involves the use of only one earphone, high-quality noise isolation and the user's concentration on music become extremely difficult.

In accordance with another example, the anti-eavesdropping device disclosed in patent US5533131 (publ. 02.07.1996, IPC H04B 3/00) is known in the art. The known device contains a face mask and on-ear headphones. The mask is provided with holes for breathing and is made to fit either to the area around the mouth and nose, or only around the mouth of the user. The device can be used to organize communication between people with ensuring isolation of their speech from strangers.

However, the known device has a low performance, since the mask used in it fetters the jaw of the user. In a situation when it becomes necessary to open your mouth wide or quickly change the vocal position, the mask design will prevent this.

The prototype of the claimed utility model is the training device disclosed in the patent for the invention KR101279046 (publ. 02.07.2013, IPC G09B 5/04). The known device is intended for individual lessons, involving the training of pronunciation without causing inconvenience to people around. The training device contains a face pad, which is represented by a mask adjacent to the face around the mouth and nose of the user when using it, over-ear headphones with two speakers installed in the insulating rings of the headphones, and adjusting straps connecting the mask with the said insulating rings. Inside the mask there is a microphone and amplifier connected to one of the speakers so that the user can hear his voice during the pronunciation training. Another speaker is designed to play sound from an external multimedia device.

However, a disadvantage of the known device is the fit of the mask to the face of the user around the nose and mouth. As in the previous case, when placing the nose inside the mask, the user's breathing may be difficult, and the user's voice will be distorted, which can negatively affect vocals.

Another common disadvantage of the known solutions is the implementation of the mask, in which the volume of the mask space is minimized in favor of ensuring the compactness of the mask. With such a performance, the sound wave from the organs of speech instantly hits an obstacle, which leads to additional distortion of the user's voice.

Utility Model Implementation

The specifics of vocals is that, firstly, the user, depending on the technique used, needs to provide intensive breathing, both with his nose and mouth. In the absence of the technical ability to breathe freely through the nose, the user's voice is distorted and becomes more muffled, since the volume of air for breathing is limited by the mask area. Secondly, the user needs to ensure freedom of movement for the jaws and facial muscles of the face. In the opposite case, when the mask is adjacent to the face of the user, it becomes difficult to apply techniques for extracting high-pitched sounds or changing the vocal position, which also leads to distortion of the voice. Thus, the present utility model is aimed, first of all, at providing sound insulation of the user's voice from others, eliminating voice distortions when it is isolated by means of the front cover, and also allows to isolate the user from external noise, and increase the usability of the device.

In accordance with figures 1 and 2, the inventive device consists of headphones 1 and a front cover 2.

As headphones 1, it is advisable to use overhead or full-size headphones with two soundproofing rings, since headphones of this type can largely isolate the user from ambient noise. Headphone speakers are installed inside the soundproofing rings of the headphones and are oriented inside the ear canal of the user.

The insulating rings of the headphones 1 and the front cover 2 can be made of a single segment of soundproof and elastic material with the formation of a connector 4, which ensures the adaptation of the device to the size of the user's head. The insulating rings can be connected using the headband 3, which is a flexible handle with a regulator or a fabric tape with a textile fastener (tape-contact, acting on the principle of a burdock), which provides the ability to adjust the distance between these rings so as to completely cover the user's ears and more securely fix the device on the user's head. For a more comfortable fixation, the device can be equipped with an additional headband in the neck. In particular, the connector 4 can also be represented by a fabric tape with a textile fastener or other device, as is implemented in the prior art technical solutions, for example, a belt with a regulator.

The faceplate 2 is an oblong box, the internal volume of which is larger than in the case of a conventional (“flattened”) mask. The specified box can be made in the form of a sphere, spheroid or convex polyhedron with an internal cavity. The part of the box in contact with the user's face can be equipped with a soft, for example, silicone, sealing edge for a more comfortable fit to the skin of the face. The increase in the space inside such a box allows you to provide a more distinct sound of the user's voice due to the fact that the sound wave from the organs of speech during its propagation inside the box does not immediately hit the obstacle. In a normal mask, the voice sounds more muffled.

The contact area of the box with the face of the user is bounded above by the area between the nose and mouth, and from below by the base of the lower jaw, preferably closer to the neck. Due to the fact that the user's nose is outside the box, the voice sounds less distorted. In addition to this, the user gets the opportunity to breathe freely through his nose. When using the device, the box closes the mouth, chin and adheres to the base of the lower jaw, closer to the neck, which allows for freedom of movement of the facial muscles of the face and jaw, eliminates their stiffness, and does not prevent an active change in vocal position.

In the walls of the box can be made one or more holes 5 for a breathing valve or duct. Microphone 6 can be installed on the surface of the box, at a distance of 5-10 cm from the user's face, opposite the direction of the sound wave so that the pickup elements of the microphone 6 are oriented in the direction of the user's mouth.

The inventive device can be connected to an external multimedia device using cable 7 with a jack or mini-jack connector. An external multimedia device can be represented, for example, by a smartphone, audio player, computer, etc. When using wireless communications, the connection can be made using Bluetooth or radio.

Using this useful model in practice allows, among other things, conducting vocals in the evening and at night without causing any inconvenience to others, in any place convenient for classes. The device can be used for singing to accompaniment or for recording, for example, using karaoke systems. Also, the implementation of the device allows the user to accompany himself in the classroom on a digital or electronic musical instrument with the transmission of sound directly to the headphone speakers. The volume level for comfortable activities can be set by the user. Such classes can be carried out both individually and in a group, regardless of the geographical location of users, combining them into a single system, for example, using the Internet, abandoning bulky equipment that amplifies sound, and at the same time, getting high-quality full-fledged music sound and voices without inconvenience to others.
