Refer to fig. 1-2.
A play adjustment system based on play distance, comprising:
and the user identification unit 1 is used for identifying the identity of the user, and the user identification unit 1 is connected with the distance acquisition unit 2. The user identification unit 1 identifies the user by means of face identification, fingerprint identification, pupil identification, and the like. The user recognition unit 1 outputs the recognition result to the distance acquisition unit 2.
The distance obtaining unit 2 is used for obtaining the distance between the user and the playing device, and the distance obtaining unit 2 is connected with the playing unit and detects the distance between the user and the playing device at intervals of preset time. The distance acquisition unit 2 acquires the actual distance between the user and the playback device.
And the playing adjusting unit 3 is used for adjusting the playing volume of the playing module and the angle of the playing module. As a preferable mode of this embodiment, when the usage scenario is consistent with the user operation habit stored in the storage unit, the playing adjusting unit 3 operates the volume and the angle of the playing module according to the user operation habit.
If the user identification unit 1 acquires that a user approaches the playback device, the user identification unit 1 identifies whether the user is a designated user, and if so, outputs a confirmation signal to the distance acquisition unit 2. The user identification unit 1 stores identification information for specifying a user, and the identification information includes identification information of identification methods such as face identification, fingerprint identification, and pupil identification.
The distance acquisition unit 2 acquires the distance between the specified user and the playback device after receiving the confirmation signal. As an implementation manner of this embodiment, the distance obtaining unit 2 may be an infrared distance measuring device, and obtains an actual linear distance between the user and the playing device.
If the distance value is not greater than the first distance threshold, the playing volume is adjusted to be the first volume value by the playing adjusting unit 3, and the angle of the playing module is adjusted to be the first angle by the playing adjusting unit 3. The first distance threshold may be set to 0-50cm, in particular to 30 cm. The first volume value may be set to 0-30%, in particular to 15%. The first angle may be set to 0-30 degrees, and particularly, may be set to 15 degrees. The first angle is an included angle formed by the playing module (loudspeaker) and a plane of the playing device, which is opposite to the user, and the first angle is an included angle of a plane parallel to the horizontal plane.
If the distance value is greater than the first distance threshold and not greater than the second distance threshold, the playing volume is adjusted to the second volume value by the playing adjusting unit 3, and the angle of the playing module is adjusted to the second angle by the playing adjusting unit 3. The first distance threshold may be set to 0-50cm, in particular to 30 cm. The second distance threshold may be set to 100 and 150cm, and may be specifically set to 130 cm. The second volume value may be set to 30-60%, in particular to 50%. The second angle may be set to 30-60 degrees, and particularly, may be set to 45 degrees.
If the distance value is greater than the second distance threshold, the playing volume is adjusted to be a third volume value by the playing adjusting unit 3, and the angle of the playing module is adjusted to be a third angle by the playing adjusting unit 3. The second distance threshold may be set to 100 and 150cm, and may be specifically set to 130 cm. The second volume value may be set to 60-90%, in particular to 80%. The second angle may be set to 60-90 degrees, and particularly may be set to 80 degrees.
As an embodiment of the invention, the method comprises the following steps: the user identification unit 1 stores the characteristics of the designated user, and if the identified user is not the designated user, the user identification unit outputs a closing signal to the distance acquisition unit 2, and the distance acquisition unit 2 stops detecting the user. The user characteristics include identification information of identification modes such as face identification, fingerprint identification, pupil identification and the like. If the current user is identified to be a non-designated user, the user identification unit 1 outputs a closing signal to the distance acquisition unit 2, and the distance acquisition unit 2 stops acquiring the user distance.

The second distance threshold may be set to 100 and 150cm, and may be specifically set to 130 cm. In this case, by increasing the distance from the playback device, it can be considered that the user feels that the volume discharged by the playback device is too large, and the playback adjusting unit 3 decreases the volume value of a preset proportion, which may be a volume value of 10%. If there are multiple times of the operation, the preset proportional volume value is sequentially reduced.
As an embodiment of the present invention, an ambient sound acquiring unit 4 is included to acquire ambient sound around the playback device, and the ambient sound acquiring unit 4 is connected to the playback adjusting unit 3. The ambient sound collecting unit collects ambient sound data including ambient noise and ambient background sound.
As an embodiment of the present invention, if the volume threshold of the ambient sound acquired by the ambient sound acquisition unit 4 is smaller than the first ambient volume threshold, the ambient sound acquisition unit 4 outputs a volume-down signal to the volume adjustment unit. The first ambient volume threshold may be set to 10-50 db, and may be specifically set to 40 db. If the volume threshold of the environmental sound acquired by the environmental sound acquisition unit 4 is smaller than the first environmental volume threshold, the environmental sound acquisition unit 4 outputs a volume reduction signal to the volume adjustment unit, and the volume adjustment unit reduces the volume by a preset proportion, where the volume by the preset proportion may be a volume value of 10%.
As an embodiment of the present invention, if the volume threshold of the ambient sound acquired by the ambient sound acquisition unit 4 is greater than the first ambient volume threshold, the ambient sound acquisition unit 4 outputs an increase volume signal to the volume adjustment unit. The first ambient volume threshold may be set to 10-50 db, and may be specifically set to 40 db. If the volume threshold of the environmental sound acquired by the environmental sound acquisition unit 4 is greater than the first environmental volume threshold, the environmental sound acquisition unit 4 outputs a volume increasing signal to the volume adjustment unit, and the volume adjustment unit increases the volume by a preset proportion, where the volume by the preset proportion may be a volume value of 10%.
As an embodiment of the present invention, if the volume of the ambient sound acquired by the ambient sound acquiring unit 4 is greater than the second ambient volume threshold, and the distance from the specified user acquired by the distance acquiring unit 2 exceeds the third distance threshold, the playback adjusting unit 3 will turn off the volume. The second ambient volume threshold may be set to 50-90 db, and may specifically be set to 80 db. The third distance threshold may be set to 150 and 200cm, and may be specifically set to 150cm.
As an embodiment of the present invention, if the volume of the ambient sound acquired by the ambient sound acquiring unit 4 is smaller than the third ambient volume threshold, and the distance from the specified user acquired by the distance acquiring unit 2 is smaller than the fourth distance threshold, the playback adjusting unit 3 will adjust the volume to the minimum volume. The third ambient volume threshold may be set to 10-50 db, and may specifically be set to 30 db. The fourth distance threshold may be set to 0-50cm, in particular to 20 cm.
