3 is a control block diagram of a vehicle equalizer apparatus according to an embodiment.

3, the vehicle equalizer apparatus includes a sensing unit 100 for sensing noise, a voice recognition unit 200 for recognizing a voice of a user recognized through a voice recognition microphone 110, An input unit 300, a display unit 500 for visually displaying sound and noise information to a user, a speaker 700 for outputting sound to the inside of the vehicle 1, a storage for storing the detected noise and the size of sound to be output Unit 800 and a control unit 400 for controlling the entirety of the equalizer apparatus for a vehicle.

Specifically, the sensing unit 100 refers to a configuration or a module that senses external noise generated outside the vehicle 1 in the interior of the vehicle 1. That is, the sensing unit 100 is installed inside the vehicle 1, and senses the noise heard by the user due to the noise outside the vehicle 1.

Here, the sensing unit 100 may include various sensors, and may include a microphone 110 for voice recognition in one embodiment.

The voice recognition microphone 110 may refer to a microphone. When a user's utterance voice is input, the voice recognition microphone 110 converts the voice into an electrical signal and transmits the voice signal to the voice recognition unit 200, and can perform preprocessing.

Specifically, the microphone 110 for voice recognition may further include an analog-to-digital converter to transmit a digital voice signal to the voice recognition unit 200. When the analog-to-digital converter is included in the voice recognition unit 200, the voice recognition microphone 110 outputs an analog voice signal, and the voice recognition unit 200 converts the analog voice signal into a digital voice signal.

In addition, the voice recognition microphone 110 can measure noise generated by external noise transmitted to the vehicle 1 in addition to the voice of the user. That is, the voice recognition microphone 110 transmits the sensed sound to the control unit 400, and the control unit 400 compares the sensed sound with other output sounds of the vehicle 1 to determine the noise.

The input unit 300 transmits a user's input command for adjusting sound in the vehicle 1 to the control unit 400. That is, the user can adjust the sound inside the vehicle 1 using the input unit 300 or remove the noise.

Specifically, the input unit 300 may include various input devices, and the first input device 33 and the second input device 52 referred to in FIG. 2 may be one example. Also, according to an embodiment of the present invention, the user can adjust the sound through the touch input unit 310 installed together with the display unit 500.

The touch input unit 310 may be provided on the AVN display, that is, on the front surface of the display unit 500 in the form of a touch panel. Specifically, when the user touches the touch panel using his / her hand, the touch input unit 310 recognizes the decompression or the human body current, converts the sensed voltage into an electric signal, and transmits the electric signal to the controller 400.

In addition to the above-mentioned examples, the input unit 300 may be formed in various forms and devices, and is not limited.

The display unit 500 displays noise and sound inside the vehicle 1 by each band and provides information to the user.

Specifically, the display unit 500 can display the noise and sound analyzed by the control unit 400 in an infographic form. Various embodiments in which the display unit 500 displays sound information will be described later in Figs. 5A to 6B and the like.

As described above, the display unit 500 can display sound information through the display of FIG. However, the present invention is not limited to this, and other visual devices that ordinary artisans can think of are also possible. Also, the display unit 500 can display the sound inside the vehicle 1 in cooperation with the user terminal, and there is no limitation.

The speaker 700 refers to a device that outputs sound based on a control command transmitted from the control unit 400. [ Specifically, the speaker 700 can output various sounds such as music reproduction, warning sound, and navigation voice guidance.

Meanwhile, according to one embodiment, the speaker 700 may output the sound adjusted based on the sound level input by the user through the input unit 300. [

For example, when the control unit 400 controls the output of the navigation guidance voice currently output to control the noise in the high-frequency range, the speaker can output the treble range in the navigation guidance voice with an increased treble range.

Further, when the user adjusts the warning sound output together with the warning lamp displayed on the cluster 41, the speaker 700 can output the sound of the warning sound at a controlled magnitude.

Meanwhile, the speaker 700 may include an amplifier (not shown) for amplifying sound, and generally includes a speaker 700 installed in the vehicle 1. That is, the speaker 700 is sufficient for controlling the audio-related apparatus of the vehicle 1, and is not limited.

The control unit 400 is a processor that controls the overall control of the vehicle equalizer apparatus.

According to an embodiment of the present invention, the controller 400 serves to adjust the sound inside the vehicle 1 by determining the external noise of the vehicle 1 heard by the user in the vehicle 1, that is, the noise.

The external noise of the vehicle 1 may be transmitted to the user in the vehicle 1 and the user may not be able to hear the music or warning sound to be reproduced. In order to solve such a problem, an embodiment of the disclosed invention determines the magnitude of noise inside the vehicle 1 due to external noise through the sensing unit 100 installed inside the vehicle.

Specifically, the control unit 400 compares the received noise with the sound reproduced from the inside of the vehicle 1. That is, since the controller 400 knows the size information of the sound outputted through the speaker 700 in the vehicle 1, the controller 400 can compare the information with the information sensed by the sensing unit to determine the noise.

In addition, the controller 400 displays the magnitude of the noise by the frequency band through the display unit 500, thereby helping the user to grasp the noise.

Thereafter, the control unit 400 controls the sound reproduced in the vehicle 1 based on the input of the user.

The operation of the controller 400 is similar to noise canceling. Here, noise cancellation refers to a technique of interrupting noise by canceling out the detected noise.

That is, the control unit 400 adjusts the sound inside the vehicle 1 to cancel the noise, and allows the user to listen to the sound inside the vehicle 1 without disturbing the noise.

In addition, the control unit 400 can store the sound of the vehicle 1 before the noise generated through the storage unit 800 is generated. When the noise due to the external noise of the vehicle 1 disappears, the control unit 400 can control the speaker 700 to reproduce the previous sound stored therein. A detailed description of the operation of the control unit 400 will be described later in detail with reference to FIGS. 7 and 8. FIG.

The storage unit 800 stores various programs and information related to the operation of the controller 400 as described above.

More specifically, the storage unit 800 may store the sound volume of the vehicle 1 before the noise by the sound band, and may also store the size of the sound input by the user. That is, the storage unit 800 stores a variety of information required for the operation of the controller 400 in conjunction with the controller 400.

The storage unit 800 may include an inactive memory device such as a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPRM (EPROM), a flash memory, Volatile memory such as a random access memory (RAM) or a hard disk, a card type memory (e.g., SD or XD memory), or an optical disk. However, the storage unit 800 is not limited thereto, and various storage media that can be considered by the designer can be used.

At least one of the control unit 400, the output unit 600 and the storage unit 800 may be integrated in a system on chip (SOC) built in a vehicle equalizer device, Lt; / RTI >

However, there is not only one system-on-chip included in the equalizer apparatus for a vehicle, but it is not limited to being integrated into only one system-on-chip because there may be a plurality of system-on-chips.

In addition, the control block diagram referred to in FIG. 3 is merely an example for explaining the disclosed invention and may include various other configurations, without limitation.

4 is a diagram schematically illustrating a relationship between a sensing unit and other sensing units located in the periphery thereof according to an exemplary embodiment.

Referring to FIG. 4, the sensing unit 100 according to one embodiment may be disposed inside the vehicle 1. In FIG. The sensing unit 100 is a module mounted with an engine for recognizing noise and human voice. The sensing unit 100 may be a component mounted on the vehicle 1 or may be an electronic device independent of the vehicle 1. [

The sensing unit 100 shown in FIG. 4 may include a microphone 110 for voice recognition.

The microphone 1 for voice recognition may be located in the vehicle 1 shown in Fig. That is, the voice recognition microphone 110 according to an embodiment of the disclosed invention may be provided with a voice recognition microphone 110 at various positions to detect noise inside the vehicle 1 with respect to various external noises.

In the example of FIG. 4, there is another microphone 110 for voice recognition, but it is also possible that only one voice recognition device exists in the vicinity and three or more voice recognition devices exist in the vicinity.

According to an embodiment of the present invention, the voice recognition microphone 110 transmits the sensed noise and the human voice to the control unit 400.

The microphone 110 for speech recognition according to another embodiment can transmit noise sensed by the speech recognition unit 200 and human voice.

The voice recognition unit 200 and the control unit 400 distinguish the human voice from the noise in the vehicle 1 due to the external noise based on the transmitted signal. At this time, the other microphone for speech recognition 110 also receives the user's voice and noise, and can extract the noise signal from the audio signal. The speech recognition unit 200 can transmit the extracted noise signal to the control unit 400. [

When the control unit 400 extracts the voice signal and the noise signal, the noise signals extracted by the other voice recognition microphones 110 may be synthesized and judged together. In this case, the sensing unit 100 can accurately measure the magnitude of the noise by reflecting the noise extracted from other positions.

The control unit 400 and the voice recognition microphone 110 are both connected through wire or wireless communication and the control unit 400 considers the size of the noise received from the voice recognition microphone 110 and the input time difference Thereby synthesizing the noise signal and comparing it with the sound of the vehicle 1.

In other words, the control unit 400 can be located in various positions within the vehicle 1, and by detecting and integrating noise in the vehicle 1 due to external noises at various positions, the control unit 400 performs analysis with high accuracy Thereby helping the user to display and control the current sound condition inside the vehicle 1.

5A and 5B are views showing an example in which the display unit displays sounds in the vehicle. 5A and 5B will be described together to avoid redundant explanations.

Referring to FIG. 5A, the display unit 500 displays the noise and the sound of the present vehicle 1 on a band basis by a display such as an AVN apparatus. The bar shape displayed on the display unit 500 indicates the size of the sound quantified in the infographic form.

On the other hand, Treble / Middle / Bass refers to the treble, middle, and bass of the current sound in equalizing.

Here, equalizing represents a function of returning a signal having an uneven frequency characteristic to the original frequency characteristic for some reason, that is, a function of adjusting a frequency of a sound.

Therefore, the screen of FIG. 5A may indicate that a high-pitched noise is being generated in the present vehicle 1.

Specifically, the bar-shaped space representing the treble in FIG. 5A is more filled than the other middle and bass. This may mean that the display unit 500 outputs to the user the fact that a lot of noise in the treble region is generated in the present vehicle 1. [

That is, the equalizer apparatus for a vehicle according to an embodiment of the present invention analyzes the noise sensed by the sensing unit 100 and displays the sound of the present vehicle 1 in the form of FIG. 5A to the user. Therefore, the user can determine the degree of noise in the vehicle 1 due to external noise.

If noises in the treble range are generated in the vehicle 1, other sounds during driving of the vehicle 1, such as navigation voice guidance, warning sound, or audio singing sounds, can be reproduced relatively low. This can interfere with the driver and other users.

Therefore, the user can control the high frequency sound region of music or sound being reproduced or reproduced in the current vehicle 1 to be outputted through the input unit 310 at a high level. That is, the user of the vehicle 1 can adjust the sound inside the vehicle 1 through the equalizer device disclosed in Fig. 5B.

5B is a diagram showing an example in which the user of the vehicle adjusts the output of sound that can be reproduced internally.

As described above, the user can touch the display unit 500 of FIG. 2 to adjust the sound of the inside of the vehicle 1. That is, the input unit 300 may include a touch input unit 310, and a user may input a control command he / she desires by touching a touch pad connected to the touch input unit 310.

Referring to FIG. 5B, a user touches a screen for adjusting the band of the equalizer screen with his / her hand. In comparison with FIG. 5A, the user adjusts the size of the treble indicating the treble in the band.

Specifically, the user lowers the Treble value of the noise shown in FIG. 5A from 6 to 3. The input unit 300 transmits the received control command to the control unit 400. Thereafter, the controller 400 controls the speaker 700 to increase the output of the treble region of the sound currently being reproduced in the vehicle 1 to cancel the noise.

5A and 5B illustrate only one embodiment of the disclosed invention. In addition to controlling the sound band of the sound, other examples of equalizing, such as volume, surround sound, and fade, And may include general operations. Also, the display form shown to the user may not necessarily be a bar form, and there is no limitation.

6A and 6B are views showing another example of adjusting the navigation guidance sound. To avoid redundant description, the following description will be made.

Referring to FIG. 6A, the display unit 500 is included in the AVN apparatus to display the current position of the vehicle 1 and guide the user to travel.

In FIG. 6A, the triangular shape indicates the position of the current vehicle, and the guide line indicated with the arrow indicates the traveling route. In addition, several icons on the left and bottom of the screen indicate navigation options and other guidance information.

In order for the current vehicle 1 to arrive at the destination parking lot according to the guide route, the vehicle 1 may turn to the right. In this case, the navigation device can output a guidance voice or a sound for guiding the guidance.

In the upper left corner of FIG. 6B, the controller 400 measures the noise in the current vehicle 1 in accordance with the time for outputting the announcement voice described above, and displays it as an infographic design.

That is, another embodiment of the disclosed invention as shown in FIG. 6B can display noise and sound inside the current vehicle 1 through shapes and shapes different from FIG. 5A. In addition, as shown in the lower left part of FIG. 6B, an input screen may be displayed to guide the user to adjust the sound in the vehicle 1.

7 is a flowchart for explaining the operation of the disclosed invention according to an embodiment.

Referring to FIG. 7, the sensing unit 100 senses noise generated in the vehicle 1 due to external noise (1001).

The form of the external noise may vary as described in FIG. However, such external noise is not necessarily transmitted to the user in the vehicle 1. [ Therefore, the sensing unit 100 senses voice and noise generated in the vehicle 1, and transmits the noise to the control unit 400 in a classified manner.

The control unit 400 analyzes the noise and displays the noise by the frequency band (1002).

Specifically, the control unit 400 can display the noise in the various forms mentioned above through the display unit 500. In addition, the control unit 400 can display only noise, and can display music and noise already reproduced in the vehicle 1 together.

Thereafter, the control unit 400 checks whether an input command for removing noise is transmitted (1003).

For example, the control unit 400 determines whether an adjustment command of a specific frequency band is input for noise removal. If there is no input command, the control unit 400 may control the display unit 500 to continuously display the noise or output another screen.

Also, the controller 400 can analyze the noise sensed by the sensing unit 100 in real time and display it in real time.

Meanwhile, when the user adjusts the frequency band, the control unit 400 receives the input command through the input unit 300 and removes or adjusts the noise according to the command (1004).

Specifically, the control unit 400 can control the sound through the output of the speaker 700. [ For example, when music is being reproduced through the AVN apparatus, the controller 400 may control the AVN apparatus or the AVN apparatus to output a sound canceling the noise through the speaker 700 through which the music is reproduced.

8 is a diagram showing an example of the operation of the control unit after noise disappears.

Referring to FIG. 8, the control unit 400 controls the display unit 500 to display noise according to the frequency band (2001). As mentioned in FIG. 7, there are many ways to display the noise, and the noise may be displayed in a simple volume rather than in a band.

In accordance with the input of the user, the control unit 400 controls the sound inside the vehicle 1 (2002).

The equalization in which the control unit 400 adjusts the sound can be controlled through the output of the speaker 700 installed in the vehicle 1. [ For example, the control unit 400 can reproduce the sound at a volume larger than the noise based on the user's input, thereby preventing a situation where the user can not hear the sound due to the noise.

Thereafter, the sensing unit 100 continuously senses the noise (2003).

If the noise disappears, the sensing unit 100 transmits information indicating that noise has disappeared to the control unit 400, and the controller 400 displays the information that the noise disappears through the display unit 500 so that the user can confirm the disappearance of the noise .

According to an embodiment of the disclosed invention, the control unit 400 may control the audio system in the vehicle 1 to return to the state in which the sound is reproduced before the noise occurs (2004) when the noise disappears.

Specifically, the controller 400 may store the size information of the noise in real time. For example, if the user is playing music through the AVN device, the control unit 400 may store the size of the reproduced sound through the storage unit 800.

If the noise is generated and the user controls the sound volume inside the vehicle 1, the controller 400 stores the size of the noise at the time of control and the size information of the sound to be reproduced before the input.

If the noise disappears, the control unit 400 may compare the magnitude of the stored noise with the magnitude of the noise sensed by the sensing unit 100 to determine that the noise has disappeared.

After the determination, the control unit 400 controls the output unit 600 based on the size of the sound in the stored vehicle 1 to reproduce the sound in the previous state. Through this, the user can listen to the previously reproduced music and the like without controlling the audio device or the like installed in the vehicle 1 again after the noise is removed, so that the user can be provided with comfort during driving or boarding.
