  The external device communication unit 10 communicates with an external device connected via the jack J under the control of the control unit 2. For example, the external device communication unit 10 receives audio data from the external device and outputs the audio data to the control unit 2. The control unit 2 outputs an audio signal based on the audio data to the audio processing unit 11 described later.

  The audio processing unit 11 includes a D / A converter, a volume, an amplifier, and the like. The audio signal input from the control unit 2 is digital / analog converted, amplified, and output from the speaker 12 at a predetermined volume.

  The power supply unit 13 is connected to the ACC power supply 14 and supplies the power supplied from the ACC power supply 14 to each unit of the in-vehicle audio device 1 when the ACC power supply 14 is on.

  Next, the power-on state and the power-off state will be described, and the function of the switch operation detection unit 6 will be described.

  The in-vehicle audio apparatus 1 according to the present embodiment is automatically activated in accordance with power supply from the ACC power supply 14 when the ACC power supply 14 is turned on, and is in a power-on state. The power-on state is a state in which power is supplied to each part of the in-vehicle audio device 1, and the in-vehicle audio device 1 can perform a normal operation. The normal operation includes outputting sound such as CD and radio, displaying various information on the display panel HP, and the like.

  When the power switch DS is operated in the power-on state, the in-vehicle audio device 1 shifts from the power-on state to the power-off state. The power-off state is a state in which the supply of power from the power supply unit 13 is restricted, and the in-vehicle audio device 1 cannot perform the normal operation described above. Therefore, in the power-off state, the in-vehicle audio device 1 does not output audio such as a CD or radio or display various information on the display panel HP. Note that the in-vehicle audio apparatus 1 according to the present embodiment shifts to the power-off state when the power switch DS is pressed for 1 second or more by the user, while the time that the power switch DS is continuously pressed is less than 1 second. In case, the source is switched.

  When the power switch DS is operated in the power off state, the in-vehicle audio device 1 shifts from the power off state to the power on state.

  The switch operation detection unit 6 executes the following processing when the power is off as described above. That is, the switch operation detection unit 6 is maintained in a state where power is supplied even when the power is off, and when any switch provided on the operation panel SP is operated, a predetermined corresponding to the switch is provided. The signal is input to the switch operation detection unit 6. Under this configuration, the switch operation detection unit 6 detects that any one of the switches is operated in the power-off state, and outputs a corresponding signal to the control unit 2. In particular, when an operation of rotating the knob portion of the rotary switch RS is performed in the power-off state, a predetermined signal is output from the rotary switch RS to the switch operation detection unit 6. When an operation is performed on the rotary switch RS in the power-off state, the switch operation detection unit 6 detects that based on an input from the rotary switch RS and outputs a corresponding signal to the control unit 2. . Processing of the control unit 2 when there is an input from the switch operation detection unit 6 in the power-off state will be described later.

  Here, conventionally, when the in-vehicle audio device 1 is in the power-off state, the user has to operate the power switch DS in order to shift the device to the power-on state. In order to operate the power switch DS, the user must confirm the position of the power switch DS and then press the power switch DS accurately, and the on-vehicle audio device 1 is a device mounted on the vehicle. In addition, there is room for improvement in user convenience. Based on the above, the vehicle-mounted audio device 1 executes the following processing.

  As described above, the in-vehicle audio device 1 changes from the power-on state to the power-off state based on the operation of the power switch DS. Here, when the in-vehicle audio device 1 is executing the source when the power-on state is changed to the power-off state, the following operation is performed.

  FIG. 3 is a flowchart showing the operation of the in-vehicle audio apparatus 1 when the power is turned off. At the start of the flowchart of FIG. 3, the in-vehicle audio device 1 is in a power-on state.

  As shown in FIG. 3, in the power-on state, the control unit 2 of the in-vehicle audio device 1 monitors whether or not the power switch DS has been operated to instruct the shift to the power-off state (step SA1).

  When it is detected that the power switch DS has been operated (step SA1: YES), the control unit 2 is information regarding the source (hereinafter referred to as “last source”) that was being executed when the power switch DS was operated. (Hereinafter referred to as “last source information”) is stored in the storage unit 3 (step SA2). The source refers to an output source of the sound output from the in-vehicle audio apparatus 1 and is a CD or a radio in this embodiment.

  In step SA2, when the last source is a radio, the control unit 2 stores information indicating that the last source is a radio and information such as the band of the radio being played and the reception frequency as last source information. 3 is stored. Further, when the last source is a CD, the control unit 2 stores information indicating that the last source is a CD and information such as a stop position at which reproduction is stopped in the storage unit 3 as last source information.

  After storing the last source information in the storage unit 3, the control unit 2 controls the power supply unit 13 to turn off the in-vehicle audio device 1 (step SA3).

  Thus, the control part 2 memorize | stores last source information in the memory | storage part 3, when transfer to a power-off state is instruct | indicated.

  Next, the operation of the in-vehicle audio apparatus 1 when the switch is operated by the user will be described with reference to the flowchart of FIG.

  As shown in FIG. 4, when a switch provided on the operation panel SP is operated, the control unit 2 detects this (step SB1). As described above, when the switch is operated in the power-off state, the control unit 2 detects this based on the input from the switch operation detection unit 6.

  In step SB1, the control unit 2 detects what the operated switch is, and, for a press-type switch other than the rotary switch RS, detects the time when the switch is pressed.

  When detecting that the switch is operated, the control unit 2 determines whether or not the in-vehicle audio device 1 is in a power-off state (step SB2).

  When it is determined that the power is not off (step SB2: NO), the control unit 2 executes normal processing (step SB3). In this case, the normal process is a process corresponding to the switch operated by the user. For example, when the user operates the switch S2, the control unit 2 controls the media device 9 to execute processing such as fast-forwarding or changing the track of the CD being reproduced.

  On the other hand, when it is determined that the power is off (step SB2: YES), the control unit 2 is a setting that turns on the power by operating any switch (hereinafter, referred to as “on setting”). It is determined whether or not there is (step SB4). The on setting can be set in advance by operating a predetermined switch provided on the operation panel SP.

  The on setting is a setting in which the in-vehicle audio device 1 is turned on when a switch other than the power switch DS is operated in the power off state. The operation of the in-vehicle audio device 1 when the on setting is set and the effect thereof will be described later.

  If the control unit 2 determines that the setting is not on (step SB4: NO), the control unit 2 executes normal processing (step SB3). The normal processing in this case is processing for continuing the power-off state when a switch other than the power switch DS is operated. That is, when a switch other than the power switch DS is operated, the in-vehicle audio device 1 does not execute an operation corresponding to the switch. When the power switch DS is operated, normal processing is processing for turning on the power. In other words, the in-vehicle audio device 1 is in a state in which normal operation can be performed by supplying power to each unit by the power supply unit 13 under the control of the control unit 2.

  On the other hand, if it is determined that the setting is on (step SB4: YES), the control unit 2 determines whether or not the switch is pressed long (step SB5). The long press means that the push-type switch is continuously pressed for a predetermined period or longer (for example, 2 seconds or longer).

  When it is determined that the switch has not been pressed for a long time (step SB5: NO), the control unit 2 supplies power to each unit by the power supply unit 13 to turn on the in-vehicle audio device 1 (step SB6).

  Next, the control unit 2 executes the last source based on the last source information stored in the storage unit 3 (step SB7). For example, when the last source information is information related to radio, the control unit 2 outputs the radio of the band and reception frequency that were output when the power was turned off based on the last source information. For example, when the last source information is information related to the CD, the control unit 2 plays the CD from the continuation of the stop position where the playback is interrupted based on the last source information.

  As described above, when the switch 2 other than the power switch DS is operated, the control unit 2 can execute the last source while the in-vehicle audio apparatus 1 is turned on, and the convenience for the user is improved. In addition, the control unit 2 enters the power-on state and executes the last source. In other words, the control unit 2 turns on and executes at least the source that the user is interested in when the power is turned off. Therefore, the control part 2 can suppress execution of the source which a user does not care about resulting from operating an unintended switch, and improves a user's convenience more. In addition, since the last source is executed when the power is turned on, it is possible to save the user from searching for the switch corresponding to the last source after the power is turned on, and the operability is improved. Further, since the device is mounted on a vehicle, distraction of attention to driving the vehicle can be suppressed by eliminating the trouble of searching for a switch corresponding to the last source.

  On the other hand, when it is determined that the switch has been pressed for a long time (step SB8: YES), the control unit 2 determines whether the operated switch is a switch related to the source (step SB8). In the present embodiment, the switch related to the source is a switch related to CD or a switch related to radio. The switches related to the CD are switches for operating the track of the CD to be reproduced, and in this embodiment, are the switch S1 and the switch S2. The switch relating to the radio is a switch for operating the output radio, and in this embodiment, is a switch S8 to a switch S14.

  When it is determined that the operated switch is not a switch related to the source based on the input signal from the switch operation detection unit 6 (step SB8: NO), the control unit 2 supplies power to each unit by the power supply unit 13, and The audio apparatus 1 is turned on (step SB6). And the control part 2 performs the last source based on the last source information which the memory | storage part 3 memorize | stores (step SB7).

  On the other hand, when the control unit 2 determines that the operated switch is a switch related to the source based on the input signal from the switch operation detection unit 6 (step SB8: YES), the power supply unit 13 supplies power to each unit. Then, the in-vehicle audio device 1 is turned on (step SB9).

  Next, the control unit 2 executes a source corresponding to the operated switch (step SB10). For example, when the switch S2 is operated, since the switch S2 is a switch related to the CD, the control unit 2 performs reproduction of the track of the CD. As described above, the switch S2 is a switch for fast-forwarding or changing the track of the CD to be reproduced. However, in step SB10, the control unit 2 does not perform fast forward or change of the CD track to be reproduced, but reproduces the CD track. Further, for example, when the switch S8 is operated, the control unit 2 outputs a radio assigned to the switch S8 because the switch S8 is a switch related to a radio. In this manner, the control unit 2 turns on the in-vehicle audio apparatus 1 by pressing and holding a switch related to the source, and executes the source corresponding to the switch. Therefore, the control unit 2 can turn on the vehicle-mounted audio device 1 and execute a source other than the last source. In particular, a desired source can be executed by a simple operation in which the user presses and holds a specific switch, and convenience is improved.

  By the way, the vehicle-mounted audio apparatus 1 in this embodiment can turn on the vehicle-mounted audio apparatus 1 by operating the rotary switch RS to execute the last source. As described above, the rotary switch RS is a switch provided so as to protrude from the operation panel SP. Therefore, the rotary switch RS is a switch that can be operated without the user visually recognizing the position. Further, as described above, the rotary switch RS is a rotary switch. A push-type switch is a switch that needs to be accurately grasped and operated, while a rotary switch can be simply turned in a predetermined direction without accurately grasping the switch to be operated. It is a switch that can be operated with.

  That is, the rotary switch RS is a switch that is easy for the user to operate. Therefore, the configuration in which the in-vehicle audio device 1 is powered on and the last source is executed by operating the rotary switch RS further improves user convenience.

  Further, as shown in FIG. 1, the rotary switch RS is a switch that occupies the area of the operation panel SP among the switches provided in the operation panel SP, in other words, a switch having the largest size. That is, the rotary switch RS is a switch that is easy for the user to operate. Therefore, the effect for the large size of the rotary switch RS has the same effect as the effect for the rotary switch RS being a switch protruding from the operation panel SP and a rotating switch.

  As described above, the in-vehicle audio device 1 (in-vehicle device) according to the present embodiment is executed when a plurality of switches other than the power switch DS that turns the power on or off and when the power is turned off. The storage unit 3 that stores the last source that is the source, and the last source that is turned on and stored in the storage unit 3 when any one of the plurality of switches is operated when the power is off. The control part 2 which performs is provided.

  Accordingly, even when a switch other than the power switch is operated, the power source is turned on and the last source can be executed, so that convenience for the user is improved.

  Further, when the control unit 2 of the in-vehicle audio device 1 according to the present embodiment is in a power-off state, when a predetermined switch is operated in a predetermined manner, the control unit 2 turns on the power and corresponds to the predetermined switch. Run the source. In particular, when the predetermined switch is pressed for a long time, the control unit 2 turns on the power and executes the source corresponding to the predetermined switch.

  Thereby, the control unit 2 can execute a source other than the last source. In particular, since the control unit 2 executes a source desired by the user by a simple operation of the user pressing and holding, the convenience is improved.

  Moreover, in the vehicle-mounted audio apparatus 1 according to the present embodiment, the switch includes a rotary switch RS that rotates, and the operation of the switch includes an operation on the rotary switch RS.

  Thereby, since rotary switch RS is a switch which a user operates easily, a user's convenience is improved.

  In the in-vehicle audio apparatus 1 according to the present embodiment, the rotary switch RS is provided so as to protrude from the operation panel SP (front surface) of the housing.

  Thereby, since rotary switch RS is a switch which a user operates easily, a user's convenience is improved.

  The above-described embodiments are merely illustrative of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.

  Further, for example, in the above-described embodiment, the analog switch is operated to turn on the in-vehicle audio apparatus 1 and the last source is executed. However, the present invention is not limited thereto, and is displayed on the touch panel, for example. It may be configured to operate a digital switch such as an icon. However, the power consumption when operating the in-vehicle audio apparatus 1 can be reduced in the configuration in which the analog switch is operated than in the configuration in which the digital switch is operated.

  For example, in the above-described embodiment, the case where the in-vehicle audio apparatus 1 is turned on and a source other than the last source is executed by pressing and holding the switch is illustrated. However, it is not limited to long press. For example, a configuration in which a vehicle other than the last source is executed by turning on the vehicle-mounted audio device 1 in a power-on state by double-clicking.

  Further, for example, the processing units in the flowcharts of FIGS. 3 and 4 are divided according to the main processing contents in order to make the processing of the control unit 2 easy to understand. The present invention is not limited by the above. The processing of the control unit 2 may be divided into many processing units depending on the processing content. Moreover, you may divide | segment so that one process unit may contain many processes.
