Definitions
- the present invention relates to the field of the equipment of theaters, and especially cinemas or theaters, or home cinema, in a dedicated place or in a living room or a living room ( "Home cinema" in English) and more particularly the equipment for 3D sound diffusion and 4D kinesthetic.
- the installation of broadcast points in the room generally corresponds to the so-called 5.1 digital systems. with 3 main screen channels, and 2 surround channels in the room and a channel specializing in very low frequencies placed behind the screen. This choice was made to offer the best possible distribution of sound in the room, but also to allow the use of sound effects more or less spectacular.
- the bass reinforcement channel (20 to 80/100 Hz) which reproduces only the most serious sounds plays a big part in the spectacular. These vibrations that spread very easily are also felt by the whole body and no longer by the single ear.
- surround EX Another type 6.1 solution, known under the trade names of surround EX or DTS-ES, is a variant of this arrangement.
- the surround channels are divided into 3 channels: Left, Right and Rear. Screen channels do not change.
- the level of listening is the same in mixing auditoriums and theaters. It generally corresponds to a reference level of 78 to 85 decibels depending on the configuration and the size of the room or listening room. It must not vary from one film to another. Because the sound levels of each scene are determined in the mix according to the effects and sensations desired with reference to this level of listening. A variation of this level would not only alter artistic intentions by changing the overall dynamics of the film, but it would also impair listening comfort by sometimes becoming too weak or dangerously too loud.
- the headrest comprises a central portion provided with at least one loudspeaker, a first lateral portion provided with at least one loudspeaker, and a second lateral portion provided with at least one loudspeaker.
- the lateral portions are disposed on each side of the central portion and generally extend substantially perpendicularly upwardly relative to the central portion.
- the headrest is configured to be connected to a source of audio signals that can generate several different audio signals.
- This document relates to a relaxation chair comprising transducers for transmitting vibrations to the body of a user for the purpose of providing vibratory or auditory stimuli for treatment of the nervous system. It is specified that these sessions of neurostimulation and relaxation can be practiced while the user listens to music or plays a video game, the sound being of course transmitted by means other than vibratory exciters integrated in the chair.
- the present invention relates, in its most general sense, to a sound diffusion system in a collective space equipped with a plurality of individual chairs each equipped with a sound diffusion means connected to a common source, characterized in that each of said broadcasting means comprises a specific correction circuit provided with a processor and a means of communication with an individual device, for reading a configuration file recorded in the individual equipment of the user of the corresponding chair. .
- This configuration file may notably consist of a digital audiogram, for example in the form of an impulse response signal.
- said digital audiogram is recorded on a remote resource (cloud, server, etc.), the chair being associated with means for downloading the corresponding file according to personalization information of the viewer sitting in the chair.
- said configuration files are recorded on a remote support, the chair having means of communication with said support according to personalization information of the user.
- said communication means is of the type Communication in a near field (NFC).
- each of said chairs comprises a display screen for displaying a pairing code with the individual equipment of the corresponding user.
- each of said chairs comprises a communication connector with the individual equipment of the corresponding user.
- the system further comprises a server for the recording of said configuration files and the calculation of an allocation information of the individual chairs according to the different configuration files saved.
- it further comprises a server for recording said configuration files and controlling a plurality of chairs installed in an area of the collective space by a common configuration file calculated according to the different individual configuration files of the shared space. users of that area.
- said common configuration file is calculated according to the different individual configuration files of the users of said zone and according to a second type of individual parameter.
- said configuration file comprises spectral filtering parameters.
- said configuration file is constituted by an impulse response and in that each of said chairs comprises an impulse response filter.
- the chairs are equipped with directional loudspeakers, with a variable directivity to allow adaptation to the viewer installed in the chair.
- said directional loudspeakers consist of sound lines, directivity controlled by a system controlled by sensors position and conformation of the viewer.
- FIG. 1 represents an exemplary embodiment of a system according to the invention.
- the auditorium is equipped with a series of armchair 1 to 6.
- Each chair is equipped with 12 to 15 directional speakers broadcasting sound to the user installed in the chair.
- Each chair is also equipped with a presence detector controlling the interruption of the broadcast by the speakers that equip it in the absence of user installed in the chair.
- the chairs 1 to 6 are also equipped with an electronic circuit 11 to 61 comprising a radio frequency receiver, for example Bluetooth for communicating with a user equipment, for example a cell phone.
- the chair comprises in the example described a display 16 for viewing a pairing code with the cell phone of the user installed in the chair.
- an application downloads a personal configuration file of the user, controlling an electronic filter controlling the sound diffusion by the speakers 12 to 15 of the chair in question.
- This configuration file is for example constituted by an XML file in which are saved the spectral filtering parameters adapted to the user, which are downloaded during the installation of the user in a chair.
- This file can also be constituted by an audiogram prepared for example by a hearing care professional and recorded or tele-transmitted to the user.
- This file is used by the circuit 21 to control a multi-band equalizer and to define an individual response adapting the sound broadcast by the speakers of the chair in which the user is installed.
- the configuration file can also be a WAV file corresponding to the recording of a impulse response, which is then operated by a convolution circuit that multiplies the signal downloaded by the user of the chair with the collective sound signal broadcast to all chairs 1 to 6 by the operator of the room.
- the chair 1 to 6 may also include a connector for connecting a tablet or a cell phone, allowing on the one hand the transfer of the configuration file and other by its electric recharge.
- the configuration file may, alternatively, be transmitted beforehand to a server distributing the files to the chairs of the users concerned in order to allow groupings in the same zone of users whose files are similar. These files can also be saved by the user in the Cloud.
- the diffusion can be identical for the armchairs of the zone considered, for example with an equalization calculated by aggregation of the individual configurations of the users grouped together in the same zone.
- This approval may be weighted by an additional parameter, for example a numerical value representative of the fidelity of the user, according to the frequency of attendance of the room or the category of price paid.
- the speakers intended for the user of a chair 1 are integrated for part of them in the adjacent chair 3 in order to reinforce sound spatialization.
- the speakers of the adjacent chair 3 are controlled by the electronic circuit 11 of the chair 1 of the user, and the file configuration transmitted by the latter to the circuit 31 of the chair 3.
- the chair can also provide means for acquiring information on the morphology of the user, for example its size, in order to control the spatialization of the diffusion of the chair in which the user is installed.
- the chairs 1 to 6 are in a variant of the cockpit chairs having in the dorsal and lateral portion of the sound bars or acoustic lines (line array in English), preferably directives with a controlled directivity to define a low aperture diffusion lobe.
- the acoustic lines consist of a network of acoustic speakers to a single dimension ("in line"), allowing the diffusion of sound with a directivity controlled by the phase and amplitude of the signal applied to each of the diffusers.
- the acoustic line has a size of between 15 and 40 centimeters, preferably of the order of 20 centimeters, and is equipped with micro-transducers whose section is between 0.5 and 2 centimeters. .
- the chair 6 at the front of the chair 4 of the user has acoustic lines facing the chair 4 of the user.
- the back of the chair 6 may also include a camera for recognizing the position of the head of the user of the chair 4 of the next row, in order to control the orientation and directivity of the sound diffusers optimally, depending on the size and the position of the head of the user of the chair 4 placed behind the chair 6 equipped with this camera.
- the camera may also be constituted by a camera disposed near the screen, for example a living room screen.
- the front armrest of the chair can each have an acoustic line dynamically directed towards the viewer's ear.
- the control of the orientation of each of the acoustic lines can be controlled by a camera analyzing the position of the wheelchair user.
- Each user receives the sound signal from 6 to 14 acoustic lines:
- the seat of the chair can include four additional acoustic lines arranged in the front-back direction, on either side of a median line to produce the effects "ground", such as the sound of a river for crossing scenes of a bridge.
- This variant brings to the viewer a rich three-dimensional sound experience close to him, while adapting this sound experience to its sensory specificities, in a public or private auditorium receiving several spectators with different sensory profiles.
- Each chair can also be equipped with a subwoofer, also controlled by the configuration file, to allow an individual adjustment of this parameter for which there is a high variability of the perception according to the user and which provides a kinesthetic effect.
- This parameter can thus be adapted to the perception of each user, from the signal distributed by a central unit, and the personal configuration file of the user occupying the chair.
- the chair may also include a footrest in which a vibrator is incorporated, to reproduce kinesthetic effects particularly noticeable to the user.
- the setting of the chairs of a listening area can take into account the personal information of each user, with a weighting of the configuration files according to parameters such as the frequency of passage of each user, or the price paid.
- a calculator calculates the aggregation of the profiles of the neighbors for a zone of the space with a frame of the variation of the dynamics.
- the broadcasting system further comprises one or more cameras for acquiring the cranial morphology of the persons present and the automatic calculation, for each of the persons identified, of data characterizing the transformations made to the sound wave by the body of a listener.
- This HRTF (Head related transfer function) data is then transmitted to the corresponding chair equipment to recreate a sound environment three-dimensional with speakers from a binaural signal common to all chairs and the application of a binaural process according to HRTF data.
- the image analysis makes it possible to extract the faces and determine for the occupant of each individual chair the type of cranial morphology by the parameter characterization such as the distance between the ears, the orientation of the interaural axis, the interaural difference in level (ILD) determined according to the morphology of the face which acts as a masking and diffracting obstacle.
- the parameter characterization such as the distance between the ears, the orientation of the interaural axis, the interaural difference in level (ILD) determined according to the morphology of the face which acts as a masking and diffracting obstacle.
- HRTF transfer function Head Related Transfer Functions
- the method involves different filtering for canceling cross paths while preserving the timbre of the record.
