Description

TELEVISION FOR AUTOMATIC SOUND ADJUSTMENT
The present invention relates to a television which automatically adjusts the sound volume according to user habits.
A television is an electronic device which transmits the broadcast from broadcasting organizations to the user as sound and image via the screen and the speakers. It has been a focus of interest since its invention and used in almost every aspect of life. Thanks to recent technological developments televisions not only transmit the broadcast to the user but also enable the user to use applications specifically developed for televisions and to connect to the Internet. These smart multimedia televisions have been very popular among users, and recent technological developments in displays have changed television viewing habits.
Changing user habits have guided the television manufacturers in providing the user with a more comfortable experience, thus creating new areas of development for television technology. Existing smart televisions acquire new features each day. However, there are still some areas which require development. For example, due to varying dimensions of the rooms in a house, there is no fixed viewing/listening distance between the user and a television, and the distance between the user and the television affects the sound level sensed by the user in the same room. This is the result of the difference in distance from the sound source and in sound reflection. Moreover, the sound level sensed by two different users which listen to the television at the same distance will be different. This is the result of different thresholds of hearing of the users. Furthermore, taking into consideration that the television is not always used from a fixed distance and the user may change his/her location in the room for any reason whatsoever, the sound level experienced by the user according to his/her listening habits continuously changes, which in turn disturbs the user. That the user has to adjust the sound level with the remote control every time adversely affects the user experience and ease of use.
By means of the present invention, the need for the user to adjust the sound level after the distance between the user and the television is eliminated.
The aim of the present invention is the realization of a dynamic sound change algorithm which automatically adjusts the sound level according to decrease/increase in the distance between the user and the television and which thus improves the listening performance of the users while viewing the television.
According to the television viewing habits and personal thresholds of hearing of the users, the television is generally viewed at a certain sound level. This sound level changes depending on the distance between the position of the user and the television. In case the user gets very close to the television for any reason, the sound level, which has been adjusted according to the farther listening position, disturbs the user who gets close to the television, and in order to prevent this, the sound level of the television is required to be turned down by means of the remote control. On the contrary, in case the user moves away from the television, the sound level is required to be increased. This causes a problem for the users in terms of ease of use.
In the dynamic sound level changing method realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, the distance between the user and the television is detected, and this data is compared with a predefined sound pressure level database and thus the sound pressure level changing based on the changing distance is adjusted.
In the dynamic sound level changing method realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, the sound pressure level (SPL) of the television is measured at a reference distance in order to understand the sound characteristics of the television.
Said sound pressure level is taken as reference. Starting from the reference point, the sound measurement point is gradually moved close to and away from the television and measurements are taken, thus determining the sound pressure levels changing based on the distance. This process is carried out from the minimum distance up to an estimated maximum distance, and thus the changing level of the sound within a certain distance range and the resulting distance/SPL information is saved in a database.
In order to make a correlation between the resulting database and the user, the user is asked to enter the desired sound level. During this process, a sensor on the television measures the distance from the user, and the sound level determined by the user, which is taken as reference, is matched with the distance information measured by the sensor.
In the embodiment of the present invention, based on the recorded distance between the user and the television and the SPL and by monitoring the position of the user with the sensor, the voltage on the television speaker is reduced and the relevant sound pressure level is optimized in order to reach the corresponding value in the predetermined database in case the user gets close to the television.
In the embodiment of the present invention, in case the user moves away from the television, the voltage on the speaker is increase and the relevant sound pressure level is optimized.
In the embodiment of the present invention, in case the user moves away from the television by a distance more than the predetermined maximum distance, the voltage on the television speaker is fixed according to the predetermined maximum distance and thus the maximum sound pressure level is limited.
In the embodiment of the present invention, in case the user gets close to the television by a distance more than the predetermined minimum distance, the voltage on the television speaker is fixed according to the predetermined minimum distance and thus the minimum sound pressure level is limited.
In an embodiment of the present invention, by means of automatic sound adjustment based on distance, the problem of the user being required to adjust the sound level again with the remote control upon changing his/her listening position is solved.
After the sound pressure level of the television is measured at a distance taken as reference, this process is repeated from the minimum television viewing distance up to the maximum distance. Information on the change in sound level by distance is recorded in a database. The user is asked to enter the desired sound level on the television, the sound level is adjusted based on the distance information received from a sensor on the television. By automatically adjusting the sound level based on distance, the need for adjusting the sound level again with the remote control is eliminated.

    - determining the maximum and minimum distance points and recording the resulting SPL/distance information in the database, and
    - measuring the distance from the user at the listening level determined by the user as per his/her preference in order to make a correlation between the resulting database and the user, and then taking said sound level as reference and matching the same with the user distance.
  2. A television as in Claim 1, characterized by the control method which detects the position of the user by using the recorded distance data between the user and the television and the SPL.
  3. A television as in any one of the above claims, characterized by the control method which decreases the voltage on the speaker and optimizes the relevant sound pressure level in order to reach the corresponding value in the predetermined database in case the user gets close to the television.
  4. A television as in any one of the above claims, characterized by the control method which increases the voltage on the speaker and optimizes the relevant sound pressure level in order to reach the corresponding value in the predetermined database in case the user moves away from the television.
  5. A television as in any one of the above claims, characterized by the control method which fixes the voltage on the television speaker according to the predetermined maximum distance in case the user moves away from the television by a distance more than a predetermined maximum distance.
