Detailed Description
Reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The following description, with reference to the drawings, is exemplary in nature and is intended to be illustrative of the invention and is not to be construed as limiting the invention.
An adaptive adjustment sound effect system 1000 based on an in-vehicle display terminal according to an embodiment of the present invention is described below with reference to fig. 1 to 6.
As shown in fig. 1, the adaptive adjusting sound effect system 1000 based on the in-vehicle display terminal may include: the system comprises a display terminal 200, a position detection device 300, a sound receiving device 400 and a data processing device 500.
The position detection device 300 is configured to detect a real-time position of the display terminal 200 and send the real-time position of the display terminal to the data processing device 500. The sound receiving apparatus 400 may include a recording unit 410, and the sound receiving apparatus 400 collects audio signals through the recording unit 410 and transmits the collected audio signals to the data processing apparatus 500. The data processing device 500 is configured to compare the audio signal with an initially set audio parameter to generate an adjustment signal when determining that the position of the display terminal 200 changes according to the real-time position of the display terminal 200, and adjust the sound emission of the display terminal 200 according to the adjustment signal.
It should be noted that the display terminal 200 may be a vehicle-mounted PAD (tablet personal computer) as a vehicle-mounted multimedia of the vehicle, and has functions of navigating, playing music/video, and radio, and the display terminal 200 may be disposed on an instrument desk of the vehicle, so as to facilitate a driver to view the display terminal 200. The position sensing device 300, which may include but is not limited to a position sensor, is an initiating part of the overall system 1000. The radio receiving device 400 and the data processing device 500 have a bidirectional communication function, and the communication form includes but is not limited to CAN (Controller Area Network), ethernet, bluetooth, WIFI (Wireless-Fidelity), and the like. The data processing device 500 is used for receiving, processing and transmitting data and is a core part of the entire system 1000.
Specifically, after the user sends a power-on command to the display terminal 200 through a key (e.g., a physical key or a touch screen key), the display terminal 200 triggers the position detection device 300 (e.g., a position sensor) to operate, detects the position of the display terminal 200 through the position detection device 300 as an initial position, and sends the initial position information to the data processing device 500, and the data processing device 500 records the position. After the user rotates the display terminal 200, the position detecting device 300 is again triggered, the position of the display terminal 200 is detected as a real-time position by the position detecting device 300, and the real-time position information is transmitted to the data processing device 500, and the data processing device 500 records the position. After acquiring the initial position and the real-time position, the data processing device 500 verifies the initial position and the real-time position, and determines whether the position of the display terminal 200 changes according to a verification result. If the verification is not changed, the data processing device 500 determines that the position of the display terminal 200 is not changed; if there is a change in the verification, the data processing device 500 determines that the position of the display terminal 200 has changed.
Further, when the data processing device 500 determines that the position of the display terminal 200 changes, the data processing device 500 sends a start instruction to the sound receiving device 400 to turn on the sound receiving device 400, so that the whole system 1000 starts to operate. During the operation of the whole system 1000, the sound receiving device 400 receives external sound through the sound recording unit 410, converts the received external sound into an audio signal, and feeds the audio signal back to the data processing device 500. The data processing device 500 compares the audio signal with the initially set audio parameter, calculates a corresponding adjustment signal through an algorithm, and transmits the adjustment signal to the display terminal 200. After receiving the adjustment signal, the display terminal 200 adjusts the sound according to the adjustment signal, and outputs the adjusted sound.
It should be noted that the above embodiment only exemplifies that the display terminal 200 rotates once, but in practical applications, a user may rotate the display terminal 200 multiple times. After the display terminal 200 is rotated each time, the position detection device 300 is triggered, and the real-time position (i.e., the position after this rotation) is obtained through the position detection device 300. After acquiring the position after the current rotation, the data processing device 500 verifies the position after the current rotation with the position after the previous rotation, compares the audio signal with the initially set audio parameter again to generate an adjustment signal when the position of the display terminal 200 changes, and adjusts the sound emission of the display terminal 200 again according to the adjustment signal.
Therefore, the system can adjust the sound effect in a self-adaptive manner when the position of the display terminal changes, so that the difference in hearing caused by the operation of the display terminal by a user can be offset, the sound field around the display terminal cannot be changed due to the position change, complicated operations such as setting and the like can be omitted, and the adjustment intelligence is realized.
It should be noted that, in other embodiments of the present invention, the data processing device 500 may also be integrated in the display terminal 200.
According to an embodiment of the present invention, as shown in fig. 2, the display terminal 200 may include a sound generating device 220, wherein the data processing device 500 is specifically configured to adjust the sound generation of the sound generating device 220 according to the adjusting signal.
Specifically, after the user rotates the display terminal 200, the real-time position of the display terminal 200 is detected by the position detecting device 300 and transmitted to the data processing device 500. The data processing device 500 judges whether the position of the display terminal 200 is changed according to the real-time position of the display terminal 200, and controls the sound receiving device 400 to be turned on if the position of the display terminal 200 is judged to be changed. The sound receiving device 400 receives external sound through the recording unit 410, converts the received external sound into an audio signal, and feeds the audio signal back to the data processing device 500. The data processing device 500 compares the audio signal with the initially set audio parameter to generate an adjustment signal, and adjusts the sound generation of the sound generating device 220 according to the adjustment signal, so that not only can the auditory difference caused by the operation of the display terminal by the user be offset, but also the sound field around the display terminal can not be changed due to the position change, and the complicated operations such as setting and the like can be omitted, thereby realizing the intellectualization of the adjustment.
It should be noted that the sound generating device 220 (e.g. speakers) is an implementation part of the whole system, and the number thereof can be set according to actual conditions, for example, as shown in fig. 3, the sound generating device 220, taking 4 speakers as an example, can be respectively disposed at the side of the display terminal 200 (e.g. a1 side, a2 side, B1 side and B2 side), or can be respectively disposed at the back of the display terminal 200, or can be disposed at the side and the back of the display 200 at the same time, and is not limited herein.
Further, according to an embodiment of the present invention, as shown in fig. 2, the sound receiving apparatus 400 may further include a sound effect identification unit 420, the sound effect identification unit 420 is configured to identify a current sound effect and send the current sound effect to the data processing apparatus 500, the data processing apparatus 500 compares the current sound effect with an initially set sound effect to determine whether the current sound effect is the same, and if the current sound effect is the same, the adjustment of the sound generating apparatus 220 is stopped; if not, the sound production of the sound production device 220 is continuously adjusted.
According to an embodiment of the present invention, as shown in fig. 2 and 3, the recording unit 410 may include a recording MIC, and the sound effect recognition unit 420 may include an identification MIC, wherein the recording MIC and the identification MIC respectively occupy separate communication channels to respectively transmit audio data to the data processing apparatus 500.
Specifically, while the data processing device 500 adjusts the generating device 220 to generate sound according to the adjustment signal, the MIC is identified in the sound receiving device 400, the sound is recorded and adjusted, the sound is converted into corresponding audio data and then sent to the data processing device 500, and then the data processing device 500 compares the current sound effect with the sound effect initially set to determine whether the current sound effect and the sound effect are the same. If the two are different, the data processing device 500 continues to send an instruction for controlling the sound receiving device 400 to turn on the sound receiving device 400 to receive external sound, and the external sound is converted into an audio signal again through the sound receiving device 400 and then sent to the data processing device 500, the data processing device 500 compares the audio signal with the initially set audio parameter again to generate an adjusting signal and sends the adjusting signal to the sound generating device 220, and the sound generating device 220 continues to adjust the sound according to the signal after receiving the adjusting signal until the data processing device 500 judges that the current sound effect is the same as the initially set sound effect, and stops adjusting the generating device 220.
It should be noted that the number of the sound recording units 410 and the sound effect identification unit 420 may be set according to actual situations, for example, as shown in fig. 3, the sound recording unit 410 may include 1 sound recording MIC, and the 1 sound recording MIC may be set at a middle position of the display terminal 200; the sound effect identification unit 420 includes 4 identifications MIC as an example, and the 4 identifications MIC may be respectively and correspondingly disposed around the speaker so as to identify the sound effect emitted by the speaker. The recorded MIC and the recognized MIC include, but are not limited to, an active MIC, a passive MIC, an analog MIC, and a digital MIC.
Therefore, the sound effect can be adjusted in a self-adaptive mode when the position of the display terminal changes, so that the difference in hearing caused by the fact that a user operates the display terminal can be offset, the situation that a sound field around the display terminal cannot change due to the position change is guaranteed, complex operations such as setting can be omitted, and adjustment intelligence is achieved.
As a specific example, the display terminal 200 is exemplified by a rotating PAD, and the position detection device 300 is exemplified by a position sensor, and as shown in fig. 4, the process of adaptively adjusting the tone effect based on the rotating PAD may include the following steps:
