Description

  The present invention relates to an AV device and a control method therefor, and in particular, a display disposed on the front surface of the main body is movable, and a portable device is inserted and stored in the main body with the display open, and the display is closed. It is suitable for use in an AV device configured to be able to operate a portable device.

  Conventionally, an in-vehicle AV that is configured so that a display disposed on the front surface of the main body is opened and a medium such as a CD (Compact Disc) or a DVD (Digital Versatile Disk) can be inserted and stored in the main body in that state. (Audio Visual) Device exists. Recently, as shown in FIG. 7, an AV device 200 is also provided which is configured so that a portable device 100 including an antenna 101 of a near field communication standard such as Bluetooth can be stored in the main body.

  Some portable devices 100 include a microphone 102 in addition to the Bluetooth antenna 101 and can be used as a hands-free device. This type of portable device 100 exchanges audio signals with a Bluetooth built-in mobile phone outside the AV device 200 via the Bluetooth antenna 101 while being housed inside the AV device 200. Then, the audio signal (received voice) received from the mobile phone is output from the speaker of the AV device 200, and the audio signal (transmitted voice) input from the microphone 102 is transmitted to the mobile phone so that the other party can make a call. Send to the side.

  Some portable devices 100 can be used for music download and playback. This type of portable device 100 exchanges audio signals with the portable audio player outside the AV device 200 via the Bluetooth antenna 101 while being stored inside the AV device 200. Then, the audio signal received from the portable audio player is output from the speaker of the AV device 200.

Here, when the portable device 100 is housed in the AV device 200 and the portable device 100 is actually operated, the display 201 of the AV device 200 is closed. Various information related to the operation is displayed on the screen of the display 201. Further, when a touch panel is disposed on the display 201, an operation for controlling the operation state can be performed by a touch operation on the touch panel. In addition, in order to make it easy to see the display on the display 201, a technique has been proposed in which the viewing angle can be changed (see, for example, Patent Document 1).
JP-A-10-197843

  However, when the portable device 100 operates, the display 201 of the AV device 200 that houses the portable device 100 is closed, which causes the following problem. For example, when the portable device 100 is used for a hands-free call, even if the Bluetooth antenna 101 of the portable device 100 is shielded by the display 201 of the AV device 200, it diffracts and flows in from the gap between the main body of the AV device 200 and the display 201. It is possible for the Bluetooth antenna 101 to catch the incoming signal and detect whether there is an incoming call in the standby state.

  However, during a call, it is difficult to use an unstable signal that diffracts and flows in from a gap, even though the Bluetooth antenna 101 must receive a signal stably to ensure a continuous audio stream. There was a problem that the call was interrupted. Further, since the microphone 102 of the portable device 100 is shielded by the display 201 of the AV device 200, there is a problem that the input sensitivity of the microphone 102 is lowered and the speaker voice cannot be captured well.

  Even when the portable device 100 is used for music download and playback, the Bluetooth antenna 101 must stably receive signals in order to secure a continuous audio stream. However, an unstable signal that is diffracted / inflowed from the gap between the main body of the AV apparatus 200 and the display 201 is difficult to do so, and there is a problem that the sound of the reproduced sound is interrupted.

The present invention has been made to solve such a problem. When a portable device housed in an AV device is operated, a sufficient received electric field strength is obtained with respect to an audio signal received through the antenna of the portable device. The purpose is to ensure a stable supply.
It is another object of the present invention to stably secure a sufficient microphone sensitivity for an audio signal input from a microphone of a portable device during operation of the portable device housed in the AV device.

  In order to solve the above-described problems, according to the present invention, an antenna in a main body and a main body according to the received electric field strength of a signal received through an antenna provided in a portable device housed in the main body of the AV device. The components of the AV equipment are driven and moved so that there are fewer elements that hinder the wireless communication with the outside. For example, the display is opened so that the degree of opening of the display arranged on the front surface of the AV device is increased. Further, the storage position is moved so that the portable device in the main body approaches the opening of the display.

  In another aspect of the present invention, depending on the sensitivity of the microphone provided in the portable device housed in the main body of the AV device, there is an element that hinders the propagation of sound between the microphone inside the main body and the outside of the main body. The constituent members of the AV equipment are driven and moved so as to reduce the number. For example, the display is opened so that the degree of opening of the display arranged on the front surface of the AV device is increased. Further, the storage position is moved so that the portable device in the main body approaches the opening of the display.

  According to the present invention configured as described above, since the portable device is housed inside the AV device, for example, the reception electric field strength necessary for securing a continuous audio stream is not sufficiently secured. In this case, an obstruction factor that prevents the reception electric field strength from being secured can be avoided by moving a component of the AV device (for example, a moving mechanism of a display or a portable device). As a result, when the portable device housed in the AV device is in operation, it is possible to stably ensure a sufficient received electric field strength for the audio signal received via the antenna of the portable device, and to prevent the occurrence of sound interruption. Is possible.

  According to another aspect of the present invention, since the portable device is housed inside the AV device, for example, when the microphone sensitivity necessary to ensure good sound quality is not sufficiently ensured, the AV device By moving the component members of the device, an obstruction factor that prevents the microphone sensitivity from being secured can be avoided. As a result, when the portable device stored in the AV device is operated, sufficient microphone sensitivity can be stably ensured for the audio signal input from the microphone.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of an AV device 10 and a portable device 20 accommodated therein according to the first embodiment. As shown in FIG. 1, the AV device 10 of this embodiment includes an audio signal selector 11, an electronic volume 12, an audio amplifier 13, a speaker 14, a display 15, a motor driver 16, a motor 17, and a microcomputer 18.

  The audio signal selector 11 is for selecting a source of an audio signal to be reproduced by the AV device 10. For example, when the AV device 10 includes a radio reception unit and a DVD (Digital Versatile Disk) reproduction unit, the audio signal selector 11 includes an audio signal from the radio reception unit, an audio signal from the DVD reproduction unit, and a portable device 20. Is selectively output.

  The electronic volume 12 includes a volume 12a, a tone controller 12b, and a fade volume 12c, and adjusts and outputs the volume of the audio signal output from the audio signal selector 11. The audio amplifier 13 amplifies and outputs the audio signal output from the electronic volume 12. The speaker 14 outputs sound based on the sound signal amplified by the sound amplifier 13.

  The display 15 displays various information related to the reproduction of the audio signal. In addition, a touch panel is arranged on the display 15 so that an operation for controlling the operation state of the radio reception unit, the DVD playback unit, or the portable device 20 can be performed by a touch operation on the touch panel. Yes.

  The display 15 is disposed on the front surface of the main body of the AV device 10. When the motor driver 16 drives the motor 17, the display 15 is movable. As shown in FIG. 7, the portable device 20 is inserted and stored in the AV device 10 with the display 15 opened, and the portable device 20 can be operated with the display 15 closed. Yes.

  FIG. 2 is a diagram illustrating a movable state of the display 15. FIG. 2 shows a state in which the main body 10 ′ of the AV device 10 and the display 15 disposed on the front surface thereof are viewed from the side. 2A shows a state where the display 15 is completely closed, and FIG. 2D shows a state where the display 15 is fully opened.

  For example, when the display 15 is opened from the closed state shown in FIG. 2A, first, the display 15 is moved forward by a predetermined amount as shown in FIG. . Thereafter, as shown in FIG. 2 (c), the display 15 starts to rotate with its lower end portion as the rotation axis, and finally the display 15 is completely opened as shown in FIG. 2 (d). When the display 15 is closed from the closed state in FIG. 2D, the procedure is reversed.

  The microcomputer 18 controls the operations of the audio signal selector 11, the display 15, and the motor driver 16 described above. That is, the microcomputer 18 controls the audio signal selector 11 so as to select an audio source instructed by the user through an operation on a touch panel arranged on the display 15. The microcomputer 18 also performs display control of various information on the display 15.

  Further, the microcomputer 18 is electrically connected to the microcomputer 25 included in the portable device 20 via the serial communication interface (I / F) 30 in a state where the portable device 20 is housed in the AV device 10. Yes. The microcomputer 18 of the AV device 10 and the microcomputer 25 of the portable device 20 exchange information via the communication I / F 30.

  Specifically, the microcomputer 18 acquires information regarding the received electric field strength of a signal received via the built-in antenna 22 provided in the portable device 20 from the portable device 20 via the communication I / F 30. In addition, the microcomputer 18 acquires information on the microphone sensitivity of the built-in microphone 21 provided in the portable device 20 from the portable device 20 via the communication I / F 30. Then, the motor driver 16 is driven according to the acquired received electric field strength and microphone sensitivity to control the degree of opening of the display 15. Thus, the microcomputer 18 of the AV device 10 corresponds to an electric field intensity acquisition unit, a microphone sensitivity acquisition unit, and a display drive unit of the present invention.

  For example, when the portable device 20 is used for a hands-free call, the microcomputer 18 first receives a call from a mobile phone (not shown) outside the AV device 10 through communication with the microcomputer 25 of the portable device 20. Determine. That is, when there is an incoming call with a mobile phone, it is notified to the portable device 20 and further notified from the microcomputer 25 of the portable device 20 to the microcomputer 18 of the AV device 10. The microcomputer 18 determines whether or not there is an incoming call depending on whether or not there is this notification. When it is determined that there is an incoming call, the above-described information on the received electric field strength and the microphone sensitivity is acquired from the portable device 20.

  Then, the motor driver 16 is driven according to the acquired received electric field strength and microphone sensitivity to control the degree of opening of the display 15. Specifically, the microcomputer 18 determines whether or not the acquired received electric field strength is equal to or higher than a predetermined level, and whether or not the microphone sensitivity is equal to or higher than a predetermined level, and when at least one of the received electric field strength and the microphone sensitivity is not equal to or higher than the predetermined level. Then, the motor driver 16 is driven to control the display 15 to open by a predetermined amount. In this state, information on the received electric field strength and microphone sensitivity is acquired from the portable device 20 again. If the acquired received electric field strength and microphone sensitivity have not yet reached the predetermined levels, the motor driver 16 is driven to place the display 15 in place. Control to open only a fixed amount.

  When the portable device 20 is used for downloading and playing music, the microcomputer 18 first determines whether or not the portable device 20 is set to a mode for downloading and playing music using the portable device 20. That is, the microcomputer 18 determines whether or not the download reproduction mode is designated by the user through the operation of the touch panel. If it is determined that the download reproduction mode is designated, the microcomputer 18 acquires information on the received electric field strength from the portable device 20 and controls the degree of opening of the display 15 according to the received electric field strength.

  Specifically, the microcomputer 18 determines whether or not the acquired received electric field strength is equal to or higher than a predetermined level. If the received electric field strength is not higher than the predetermined level, the microcomputer 18 drives the motor driver 16 to move the display 15 by a predetermined amount. Control to open. In this state, information on the received electric field strength is acquired from the portable device 20 again. If the acquired received electric field strength has not yet reached a predetermined level, the motor driver 16 is driven so that the display 15 is further opened by a predetermined amount. Control.

  Next, the internal configuration of the portable device 20 will be described. As shown in FIG. 1, the portable device 20 includes a built-in microphone 21, a built-in antenna 22, a CODEC (COder-DECoder) 23, a Bluetooth unit 24, and a microcomputer 25. The CODEC 23 converts an analog audio signal input from the built-in microphone 21 into digital audio data and outputs the digital audio data to the Bluetooth unit 24. The CODEC 23 converts the digital audio data input from the Bluetooth unit 24 into an analog audio signal and outputs the analog audio signal to the audio signal selector 11 of the AV device 10.

  For example, when the portable device 20 is used for a hands-free call, the CODEC 23 converts an analog signal of transmission voice input from the built-in microphone 21 into digital voice data and outputs the digital voice data to the Bluetooth unit 24. The CODEC 23 converts the received voice digital data supplied from the Bluetooth unit 24 into an analog voice signal and outputs the analog voice signal to the voice signal selector 11.

  When the portable device 20 is used for music download and playback, the CODEC 23 converts the music data decoded by the Bluetooth unit 24 into an analog audio signal and outputs the analog audio signal to the audio signal selector 11.

  The Bluetooth unit 24 performs Bluetooth communication with an external device (not shown) via the built-in antenna 22. For example, when the portable device 20 is used for a hands-free call, the Bluetooth unit 24 transmits digital audio data of the transmitted voice input from the CODEC 23 to a mobile phone (not shown) via the built-in antenna 22. Further, the Bluetooth unit 24 receives digital voice data of received voice from a mobile phone (not shown) via the built-in antenna 22 and outputs it to the CODEC 23.

  When the portable device 20 is used for downloading and playing music, the Bluetooth unit 24 receives music data from a portable audio player (not shown) via the built-in antenna 22, decodes it, and outputs it to the CODEC 23.

  In addition, the Bluetooth unit 24 detects the received electric field strength of the signal received via the built-in antenna 22 and outputs information indicating the strength level to the microcomputer 25. The Bluetooth unit 24 detects the microphone sensitivity of the built-in microphone 21 based on the signal level of the transmitted voice input from the CODEC 23 and outputs information representing the sensitivity level to the microcomputer 25. The microcomputer 25 outputs information regarding the received electric field strength and microphone sensitivity input from the Bluetooth unit 24 to the microcomputer 18 of the AV device 10 via the communication I / F 30.

  Next, the operation of the AV device 10 configured as described above will be described. FIG. 3 is a flowchart illustrating an operation example of the AV device 10 according to the first embodiment. Here, an operation when the portable device 20 is used for a hands-free call is shown. First, the microcomputer 18 determines whether or not there is an incoming call from a mobile phone (not shown) based on information sent from the microcomputer 25 of the portable device 20 (step S1). If there is no incoming call, the process of step S1 is repeated.

  When the portable device 20 is used for a hands-free call, even if the built-in antenna 22 of the portable device 20 is shielded by the display 15 of the AV device 10, it diffracts and flows in from the gap between the main body of the AV device 10 and the display 15. The incoming signal can be detected by the built-in antenna 22 and the presence or absence of an incoming call can be detected. That is, when an incoming call is received by the mobile phone, this is notified from the mobile phone to the portable device 20 in the AV device 10 by wireless communication. Further, the portable device 20 notifies the microcomputer 18 of the AV device 10 that there is an incoming call.

  When the microcomputer 18 determines that there is an incoming call in this way, information on the received electric field strength of the signal received via the built-in antenna 22 of the portable device 20 and information on the microphone sensitivity of the built-in microphone 21 of the portable device 20. Are obtained from the microcomputer 25 of the portable device 20 (step S2). Then, it is determined whether the acquired received electric field strength is equal to or higher than a first level required for stable communication (step S3).

  Here, when the received electric field strength is equal to or higher than the first level, it is determined whether or not the microphone sensitivity acquired in step S2 is equal to or higher than the second level required for performing voice input in a good state. Determine (step S4). When the received electric field strength is not equal to or higher than the first level or the microphone sensitivity is not equal to or higher than the second level, the microcomputer 18 controls the motor driver 16 to open the display 15 by a predetermined amount (step) S5).

  Then, returning to Step S2, the loop processing of Steps S2 to S5 is repeatedly executed until the received electric field strength becomes equal to or higher than the first level and the microphone sensitivity becomes equal to or higher than the second level. When both the received electric field strength and the microphone sensitivity are equal to or higher than a predetermined level, the microcomputer 18 controls the portable device 20 so as to shift to the call mode (step S6). As a result, a hands-free call can be performed via the portable device 20.

  During the hands-free call, the microcomputer 18 determines whether or not the call has ended based on information sent from the microcomputer 25 of the portable device 20 (step S7). In other words, when the call is ended with the mobile phone, this is notified to the portable device 20 and further notified from the microcomputer 25 of the portable device 20 to the microcomputer 18 of the AV device 10. The microcomputer 18 determines whether or not the call is ended depending on whether or not the notification is received.

  If it is determined that the call has ended, the microcomputer 18 drives the motor driver 16 to return the display 15 to the original position before opening the display 15 in step S5 (step S8). Then, it returns to step S1.

  As described above in detail, in the first embodiment, the received electric field strength and microphone sensitivity in the portable device 20 are acquired, and the degree of opening of the display 15 is controlled according to the received electric field strength and microphone sensitivity. Yes. Thereby, when the built-in antenna 22 and the built-in microphone 21 of the portable device 20 are shielded by the display 15 and the received electric field strength and the microphone sensitivity are lowered, the display 15 is automatically opened, and a sufficient received electric field strength is obtained. And microphone sensitivity will be secured.

  Therefore, when the portable device 20 housed in the AV device 10 is in operation, a sufficient received electric field strength can be stably secured with respect to the audio signal received via the built-in antenna 22 of the portable device 20, and the occurrence of sound interruption is generated. Can be prevented. In addition, it is possible to stably secure sufficient microphone sensitivity with respect to the audio signal input from the built-in microphone 21, and it is possible to ensure good sound quality with respect to the input audio.

  In the first embodiment, the display 15 is gradually opened by a predetermined amount and stopped when necessary reception electric field strength and microphone sensitivity can be secured. On the other hand, the display 15 may be completely opened as shown in FIG. 2D by a single operation. However, since the display screen of the display 15 cannot be seen and the touch panel cannot be operated in the state of FIG. 2D, the method of gradually opening the display 15 as in the above-described embodiment is preferable.

  Moreover, although the said 1st Embodiment demonstrated the example which monitors both receiving electric field strength and microphone sensitivity, when using the portable apparatus 20 for hands-free call, this invention is not limited to this. For example, when the portable device 20 does not include a microphone and the microphone is installed outside the AV device 10, only the received electric field intensity may be monitored.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a diagram illustrating a configuration example of the AV device 10 and the portable device 20 accommodated therein according to the second embodiment. In FIG. 4, components having the same reference numerals as those shown in FIG. 1 have the same functions, and thus redundant description is omitted here.

  As shown in FIG. 4, the configuration of the portable device 20 is the same as that of the first embodiment. On the other hand, the AV device 10 includes a moving mechanism 19 for the portable device 20 instead of the motor driver 16 and the motor 17. The moving mechanism 19 functions to move the storage position of the portable device 20 in the AV device 10 according to control from the microcomputer 18.

  FIG. 5 is an external view of the display 15 as viewed from the front. As shown in FIG. 5, in the second embodiment, an opening 51 is provided at a predetermined position of the display 15 (in the example of FIG. 5, the upper left position of the front panel). The opening 51 is a hole that penetrates from the front surface to the back surface of the display 15. The opening 51 is provided with a shutter that can be electrically opened and closed in order to prevent dust from entering the AV device 10 and is normally closed.

  The microcomputer 18 controls the opening / closing of the shutter of the opening 51 according to the information on the received electric field intensity and the microphone sensitivity sent from the microcomputer 25 of the portable device 20 and drives the moving mechanism 19 to drive the portable device 20.

FIG. 6 shows a state in which the main body 10 ′ of the AV device 10 and the display 15 disposed on the front surface thereof are viewed from the side. Although not shown in FIG. 6, an insertion port for inserting the portable device 20 into the AV device 10 is provided in the upper portion of the main body 10 ′ as shown in FIG.

  FIG. 6A shows the storage state of the portable device 20 and the open / closed state of the opening 51 in a steady state. The portable device 20 inserted from the insertion port of the AV device 10 moves inside the AV device 10 by the moving mechanism 19 and is stored in the lower part of the main body 10 'as shown in FIG. At this time, the shutter of the opening 51 is closed so that dust does not enter the AV device 10.

  On the other hand, the microcomputer 18 of the AV device 10 performs a hands-free call or music download reproduction when at least one of the received electric field intensity and the microphone sensitivity acquired from the microcomputer 25 of the portable device 20 is not equal to or higher than a predetermined level. The moving mechanism 19 is driven to control the portable device 20 so as to approach the opening 51 as shown in FIG. 6B, and to control the shutter of the opening 51 to open. When the hands-free call or music download / playback is completed, the portable device 20 is controlled to return to the original position shown in FIG. 6A and the shutter of the opening 51 is closed.

  As described above in detail, in the second embodiment, the received electric field strength and microphone sensitivity in the portable device 20 are acquired, and when the received electric field strength and microphone sensitivity do not reach a predetermined level, the portable device 20 is stored. The position is controlled so as to approach the opening 51, and the shutter of the opening 51 is opened. Thereby, when the built-in antenna 22 and the built-in microphone 21 of the portable device 20 are shielded by the display 15 and the received electric field strength and the microphone sensitivity are lowered, the shutter of the opening 51 is automatically opened, By moving the storage position so that the portable device 20 approaches the opened opening 51, sufficient received electric field strength and microphone sensitivity can be ensured.

  Therefore, when the portable device 20 housed in the AV device 10 is in operation, a sufficient received electric field strength can be stably secured with respect to the audio signal received via the built-in antenna 22 of the portable device 20, and the occurrence of sound interruption is generated. Can be prevented. In addition, it is possible to stably secure sufficient microphone sensitivity with respect to the audio signal input from the built-in microphone 21, and it is possible to ensure good sound quality with respect to the input audio.

  In the second embodiment, the example in which the portable device 20 is housed in the lower part of the AV device 10 as shown in FIG. 6A in the steady state has been described, but the present invention is not limited to this. For example, the portable device 20 may be housed in the upper part of the AV device 10 as shown in FIG. In this case, the moving mechanism 19 becomes unnecessary, and the microcomputer 18 only needs to control the opening / closing of the shutter of the opening 51 according to the received electric field strength and the microphone sensitivity.

  Moreover, although the said 2nd Embodiment demonstrated the example which equips the upper part of the display 15 with the opening part 51, this invention is not limited to this. For example, the opening 51 may be provided at the lower part of the display 15. In this case, if the storage position of the portable device 20 in the steady state is the lower portion of the AV device 10 as shown in FIG. 6A, the microcomputer 18 opens and closes the shutter of the opening 51 according to the received electric field strength and the microphone sensitivity.
