[Schematic configuration of portable terminal device]
FIG. 1 is a block diagram showing a main configuration of a mobile terminal device 1 according to Embodiment 1 of the present invention. FIG. 2 is a schematic diagram showing the appearance of the mobile terminal device 1. As shown in FIGS. 1 and 2, the mobile terminal device 1 includes a housing 2, a proximity sensor 20, a grip sensor 21, an acceleration sensor 22, a microphone 23, an audio output unit 24, a display 25, and a control unit 10. .

  The mobile terminal device 1 has a call function. The housing 2 stores a circuit board and the like inside, and the above-described components are provided on the outside and inside of the housing 2.

  The display 25 is a device for displaying various information such as images.

  The microphone 23 (voice input unit) receives an input of voice that reaches the mobile terminal device 1. Specifically, the microphone 23 receives voice such as a call from the user to the other party of the telephone. The microphone 23 is controlled in microphone gain (gain of the audio input unit) by the audio input control unit 14 described later. When the microphone 23 makes a call with the mobile terminal device 1 close to the user's face in the housing 2, the microphone 23 is placed on the lower portion of the housing 2 (the lower portion of the display 25) while holding the mobile terminal device 1. Has been placed. In other words, the microphone 23 is located in the vicinity of the user's mouth when making a call in a state where the mobile terminal device 1 is close to the user's face, that is, in a state where the user's face is not separated from the mobile terminal device 1. Further, it is disposed in the housing 2.

  The audio output unit 24 outputs audio based on an audio signal transmitted from the call destination to the mobile terminal device 1. Specifically, voice such as a call from a telephone partner is output. The audio output unit 24 includes a receiver 24a and a speaker 24b having a higher sound pressure level than the receiver 24a. The audio output unit 24 is designated by the audio output control unit 15 described later as to which audio is output from the receiver 24a or the speaker 24b, and the size of the output audio is controlled.

  When a call is made with the portable terminal device 1 close to the user's face in the housing 2, the receiver 24 a is placed on the upper portion of the housing 2 (upper portion of the display 25) with the user holding the portable terminal device 1. Has been placed. In other words, the receiver 24a is positioned in the vicinity of the user's ear when making a call in a state in which the mobile terminal device 1 is close to the user's face, that is, in a state where the user's face is not separated from the mobile terminal device 1. Further, it is disposed in the housing 2. In the housing 2, the installation position of the speaker 24b is not particularly limited.

  The proximity sensor 20 detects the proximity of the face to the housing 2 of the mobile terminal device 1. Specifically, the proximity sensor 20 includes an upper proximity sensor 20a and a lower proximity sensor 20b. The upper proximity sensor 20a is located in the vicinity of the receiver 24a, that is, in a case where the user holds the mobile terminal device 1 and makes a phone call while holding the mobile terminal device 1 close to the user's face. It is arranged on the upper part of the body 2 (upper part of the display 25). The upper proximity sensor 20a detects that the user's face, in particular, the temporal region and the ear are present at positions close to the mobile terminal device 1. On the other hand, the lower proximity sensor 20b is located near the microphone 23, that is, when the user holds the mobile terminal device 1 in a state where the mobile terminal device 1 is close to the user's face, It arrange | positions at the lower part (lower part of the display 25) of the housing | casing 2 to perform. The lower proximity sensor 20b detects that the user's face, in particular, the vicinity of the chin and the mouth are present at positions close to the mobile terminal device 1. And the upper proximity sensor 20a and the lower proximity sensor 20b will transmit a detection signal to the proximity detection part 11 mentioned later, if the proximity | contact object to the portable terminal device 1 is detected.

  The grip sensor 21 detects that the mobile terminal device 1 is gripped by the user's hand (the mobile terminal device 1 is held by the hand, in other words, the hand is attached to the grip sensor 21). There are, for example, two grip sensors 21, which are disposed on opposite sides of the housing 2 at the opposite ends of the surface on which the display 25 is disposed. When the grip sensor 21 detects that the mobile terminal device 1 is gripped, the grip sensor 21 transmits a detection signal to the grip detection unit 16 described later.

  The acceleration sensor 22 detects the acceleration of the mobile terminal device 1 itself. In other words, the acceleration sensor detects that the mobile terminal device 1 is in a stationary state. When the acceleration sensor 22 detects that the mobile terminal device 1 is stationary, the acceleration sensor 22 transmits a detection signal to an acceleration detection unit 17 described later.

(Control part)
As shown in FIG. 1, the control unit 10 includes a proximity detection unit 11, a state detection unit 12, a voice setting unit 13, a voice input control unit 14, a voice output control unit 15, a grip detection unit 16, an acceleration detection unit 17, and a voice. A recognition unit 18 and a display control unit 19 are provided.

  When the proximity detection unit 11 detects the proximity of the user's face to the mobile terminal device 1 by the upper proximity sensor 20a and the lower proximity sensor 20b, the proximity detection unit 11 acquires the detection signal and transmits the detection result to the state detection unit 12. To do. When the grip sensor 21 detects gripping of the mobile terminal device 1, the grip detection unit 16 acquires a detection signal and transmits the detection result to the state detection unit 12. When the acceleration sensor 22 detects the acceleration of the mobile terminal device 1 itself, the acceleration detection unit 17 acquires a detection signal and transmits the detection result to the state detection unit 12.

  Here, regarding the positional relationship between the mobile terminal device 1 and the user when the user is talking with the mobile terminal device 1, the following states are conceivable. (A) A state in which the face is approaching the mobile terminal device 1 and (B) a state in which the mobile terminal device 1 is away from the face.

  Further, in the state (A), the following states are further conceivable. (A-1) A state where the ear and the mouth are close to the mobile terminal device 1 (normal state). (A-2) A state in which only the ear is close to the mobile terminal device 1 and the mouth is not close to the mobile terminal device 1 (upper proximity state). (A-3) A state in which only the mouth is close to the mobile terminal device 1 and the ear is not close to the mobile terminal device 1 (lower proximity state).

  Further, in the state (B), the following states are further conceivable. (B-1) A state in which the mobile terminal device 1 is gripped (non-proximity gripping state, first state). (B-2) A state where the mobile terminal device 1 is not gripped and is stationary (stationary state, second state). The non-proximity gripping state is, for example, a state in which the user is holding the mobile terminal device 1 with his hand and looking at the display 25 away from the face. The stationary state is a state in which the user is talking while the user does not hold the mobile terminal device 1 but puts it on a desk or the like. This is the case, for example, when the user is using the voice conversation application while placing the portable terminal device 1 on a desk while cooking or changing clothes. The magnitude of the required voice output and the magnitude of the microphone gain are different between the non-proximity gripping state and the stationary state.

  Based on the detection results of the proximity detection unit 11, the grip detection unit 16, and the acceleration detection unit 17, the state detection unit 12 includes the above-described normal state, upper proximity state, lower proximity state, non-proximity gripping state, It is detected whether the state is stationary or stationary. In other words, based on the detection results of the proximity detection unit 11, the grip detection unit 16, and the acceleration detection unit 17, the state detection unit 12 is gripped by the hand while the device is away from the user's face. A non-proximity gripping state (first state), and a stationary state (first state) in which the device is not gripped by a hand and is stationary in a state where the device is separated from the user's face 2 states) at least.

  Specifically, the state detection unit 12 detects each state of the mobile terminal device 1 as shown in the following (a) to (e). (A) When both the upper proximity sensor 20a and the lower proximity sensor 20b detect proximity objects, and when the grip sensor 21 detects that the mobile terminal device 1 is held by the user's hand (upper proximity sensor 20a And the lower proximity sensor 20b have a close reaction and the grip sensor 21 has detected grip)), it is assumed that the mobile terminal device 1 is in a normal state. (B) The proximity sensor 20a detects a proximity object, the grip sensor 21 detects that the mobile terminal device 1 is gripped by the user's hand, and the bottom proximity sensor 20b does not detect a proximity object ( Assume that only the upper proximity sensor 20a has a proximity reaction and the grip sensor 21 detects gripping), and the mobile terminal device 1 is in the upper proximity state. (C) When the proximity sensor 20b detects a proximity object, and the grip sensor 21 detects that the mobile terminal device 1 is gripped by the user's hand, and the proximity sensor 20a does not detect a proximity object ( Assume that only the lower proximity sensor 20b has a proximity reaction and the grip sensor 21 detects gripping), and the mobile terminal device 1 is in the lower proximity state. (D) When there is no detection of a proximity object in the upper proximity sensor 20a and the lower proximity sensor 20b, and there is a detection that the portable terminal device 1 is held by the user's hand in the grip sensor 21 (the upper proximity sensor 20a, and Assume that the mobile terminal device 1 is in a non-proximity gripping state when the lower proximity sensor 20b has no close reaction and the gripping sensor 21 detects gripping). (E) When the grip sensor 21 detects that the mobile terminal device 1 is gripped by the user's hand and the acceleration sensor 22 does not detect the acceleration of the mobile terminal device 1 itself (the upper proximity sensor 20a and the lower sensor If the proximity sensor 20b has no proximity reaction, the grip sensor 21 does not detect gripping, and the acceleration sensor 22 detects stillness), the mobile terminal device 1 is assumed to be stationary.

  The state detection unit 12 transmits the detected state of the mobile terminal device 1 to the voice setting unit 13.

  The voice setting unit 13 sets at least one of the magnitude of the output of the voice output unit 24 and the magnitude of the microphone gain of the microphone 23 according to the state of the mobile terminal device 1 transmitted from the state detection unit 12. Specifically, the voice setting unit 13 sets the magnitude of the output of the voice output unit 24 and the magnitude of the microphone gain of the microphone 23 as shown in (I) to (V) below. (I) When the mobile terminal device 1 is in a normal state, the audio output destination is the receiver 24a, and the output of the receiver 24a is set to the receiver level. Further, the microphone gain of the microphone 23 is set to the handset level. (II) When the mobile terminal device 1 is in the upper proximity state, the audio output destination is the receiver 24a, and the output of the receiver 24a is set to the receiver level. Further, the microphone gain of the microphone 23 is set larger than the handset level. (III) When the mobile terminal device 1 is in the lower proximity state, the audio output destination is the receiver 24a, and the output of the receiver 24a is set to be larger than the receiver level. Further, the microphone gain of the microphone 23 is set to the handset level. (IV) When the mobile terminal device 1 is in the non-proximity gripping state, the audio output destination is the speaker 24b, and the output of the speaker 24b is set to the speaker level. Further, the microphone gain of the microphone 23 is set to the hands-free level. (V) When the mobile terminal device 1 is stationary, the audio output destination is the speaker 24b, and the output of the speaker 24b is set larger than the speaker level. Further, the microphone gain of the microphone 23 is set to be larger than the hands-free level.

  In this embodiment, it is assumed that the speaker level is higher than the receiver level and the handsfree level is higher than the handset level. The speaker level set in (IV) is higher than the output level of the receiver 24a set in (III), and the hands-free level set in (IV) is the same as in (II). It is larger than the set microphone gain. That is, the magnitude of the microphone gain and the sound output when the mobile terminal device 1 is away from the user's face is greater than the amount of the microphone gain and the sound output when the mobile terminal device 1 is not away from the user's face. Is also big.

  The voice setting unit 13 transmits the set magnitude of the microphone gain to the voice input control unit 14. The audio setting unit 13 transmits the set audio output destination and the audio output level to the audio output control unit 15.

  The voice input control unit 14 controls the microphone gain of the microphone 23 based on the setting by the voice setting unit 13. In addition, the audio output control unit 15 selects the audio output destination (the receiver 24a or the speaker 24b) in the audio output unit 24 based on the setting by the audio setting unit 13, and the output level of the audio from the receiver 24a / speaker 24b. To control.

  When the mobile terminal device 1 is in the lower proximity state, the user may be trying to make the mobile terminal device 1 recognize voice. In that case, when the mobile terminal device 1 is in the lower proximity state, the state detection unit 12 may further transmit a signal indicating that the mobile terminal device 1 is in the lower proximity state to the voice recognition unit 18. When the voice recognition unit 18 receives the signal from the state detection unit 12, for example, it activates a voice recognition application to recognize the voice input to the microphone 23, and displays text data extracted from the recognized voice. 25 may be transmitted to the display control unit 19 so as to be displayed. Further, the mobile terminal device 1 may access external data (not shown) based on the text data and perform a search process.

[Voice setting processing]
FIG. 3 is a flowchart showing an example of the voice setting process of the mobile terminal device 1.

  First, a call is started by the user on the mobile terminal device 1. When the call is started, the upper proximity sensor 20a and the lower proximity sensor 20b start detecting the proximity of the user's face to the mobile terminal device 1, and the grip sensor 21 starts detecting the grip to the mobile terminal device 1. The acceleration sensor 22 starts detecting the acceleration of the mobile terminal device 1 itself (stillness of the mobile terminal device 1).

  In addition, the state detection unit 12 determines whether or not the detection result is “the upper proximity sensor 20a and the lower proximity sensor 20b have a close reaction and the grip sensor 21 has grip detection” (S1). If the detection result is “the upper proximity sensor 20a and the lower proximity sensor 20b have a close reaction and the grip sensor 21 has detected grip” (YES in S1), the state detection unit 12 determines whether the mobile terminal device 1 Is sent to the voice setting unit 13. When the voice setting unit 13 receives from the state detection unit 12 that the mobile terminal device 1 is in the normal state, the voice setting unit 13 sets the output destination of the voice to the receiver 24a and sets the output of the receiver 24a to the receiver level. The microphone gain is set to the handset level (S6). Then, based on the setting made by the audio setting unit 13, the audio input control unit 14 controls the microphone gain of the microphone 23 to be set, and the audio output control unit 15 seems to have set the output of the receiver 24a. To control. Thereafter, the process returns to S1.

  If it is not the detection result that “the upper proximity sensor 20a and the lower proximity sensor 20b have a close reaction and the grip sensor 21 has a grip detection” (NO in S1), the state detection unit 12 determines that “the upper proximity sensor 20 It is determined whether or not the detection result indicates that only 20a has a close reaction and the grip sensor 21 has detected grip (S2). When the detection result indicates that only the upper proximity sensor 20a has a proximity reaction and the grip sensor 21 has detected grip (YES in S2), the state detection unit 12 indicates that the mobile terminal device 1 is in the upper proximity state. It is transmitted to the voice setting unit 13. When the voice setting unit 13 receives from the state detection unit 12 that the mobile terminal device 1 is in the upper proximity state, the voice setting unit 13 sets the output destination of the voice to the receiver 24a and sets the output of the receiver 24a to the receiver level. Is set larger than the handset level (S7). Then, based on the setting made by the audio setting unit 13, the audio input control unit 14 controls the microphone gain of the microphone 23 to be set, and the audio output control unit 15 seems to have set the output of the receiver 24a. To control. Thereafter, the process returns to S1.

  If it is not the detection result “only the upper proximity sensor 20a has a proximity reaction and the grip sensor 21 has a grip detection” (NO in S2), the state detection unit 12 determines that “only the lower proximity sensor 20b is in proximity” It is determined whether or not the detection result is “There is a reaction and the grip sensor 21 detects grip” (S3). When the detection result indicates that only the lower proximity sensor 20b has a proximity reaction and the grip sensor 21 has detected grip (YES in S3), the state detection unit 12 indicates that the mobile terminal device 1 is in the lower proximity state. It is transmitted to the voice setting unit 13. When the voice setting unit 13 receives from the state detection unit 12 that the portable terminal device 1 is in the lower proximity state, the voice setting unit 13 sets the output destination of the voice to be the receiver 24a and sets the output of the receiver 24a to be larger than the receiver level. The microphone gain of 23 is set to the handset level (S8). Then, based on the setting made by the audio setting unit 13, the audio input control unit 14 controls the microphone gain of the microphone 23 to be set, and the audio output control unit 15 seems to have set the output of the receiver 24a. To control. Thereafter, the process returns to S1.

  If it is not the detection result that “the lower proximity sensor 20b alone has a proximity reaction and the grip sensor 21 has a grip detection” (NO in S3), “the upper proximity sensor 20a and the lower proximity sensor 20b have a proximity response. It is determined whether or not the detection result is “There is no grip and the grip sensor 21 detects grip” (S4). If the detection result indicates that there is no proximity reaction in the upper proximity sensor 20a and the lower proximity sensor 20b and the grip sensor 21 has detected grip (YES in S4), the state detection unit 12 determines that the mobile terminal device 1 Is in the non-proximity gripping state, is transmitted to the voice setting unit 13. When the voice setting unit 13 receives from the state detection unit 12 that the mobile terminal device 1 is in the non-proximity gripping state, the voice setting unit 13 sets the voice output destination to the speaker 24b and sets the output of the speaker 24b to the speaker level, and the microphone. The microphone gain of 23 is set to the hands-free level (S9). Then, based on the setting made by the audio setting unit 13, the audio input control unit 14 controls the microphone gain of the microphone 23 to be set, and the audio output control unit 15 seems to have set the output of the speaker 24b. To control. Thereafter, the process returns to S1.

  If the detection result does not indicate that the upper proximity sensor 20a and the lower proximity sensor 20b have no proximity reaction and the grip sensor 21 has detected grip (NO in S4), the state detection unit 12 determines that the upper sensor 20a and the lower proximity sensor 20b, it is determined whether or not the detection result indicates that there is no response of proximity, the grip sensor 21 does not detect grip, and the acceleration sensor 22 detects a stationary state (S5). When the detection result is “the upper proximity sensor 20a and the lower proximity sensor 20b have no proximity reaction, the grip sensor 21 does not detect grip, and the acceleration sensor 22 detects stillness” (YES in S5). The state detection unit 12 transmits to the voice setting unit 13 that the mobile terminal device 1 is in a stationary state. When the voice setting unit 13 receives from the state detection unit 12 that the mobile terminal device 1 is in a stationary state, the voice setting unit 13 sets the voice output destination as the speaker 24b and sets the output of the speaker 24b to be larger than the speaker level, and the microphone 23 Is set to be larger than the hands-free level (S10). Then, based on the setting made by the audio setting unit 13, the audio input control unit 14 controls the microphone gain of the microphone 23 to be set, and the audio output control unit 15 seems to have set the output of the speaker 24b. To control. Thereafter, the process returns to S1. In addition, when the detection result does not indicate that there is no proximity reaction in the upper proximity sensor 20a and the lower proximity sensor 20b, the grip sensor 21 does not detect grip, and the acceleration sensor 22 detects stillness (NO in S5). , The process returns to S1.

  As described above, the mobile terminal device 1 detects the non-proximity gripping state and the stationary state in addition to the normal state, the upper proximity state, and the lower proximity state, and the microphone gain of the microphone 23 and the receiver 24a or speaker. By adjusting the volume of 24b, the microphone gain of the microphone 23 and the volume of the receiver 24a or the speaker 24b can be automatically adjusted more appropriately. Thereby, the user can use the portable terminal device 1 at a comfortable volume, and the portable terminal device 1 becomes easier to use.

  In this embodiment, the microphone gain value of the microphone 23 is stored in advance in the voice input control unit 14 in association with each state. However, every time it is set, for example, ambient noise is considered. May be set. Similarly, the volume value of the receiver 24a or the speaker 24b is assumed to be stored in advance in the audio output control unit 15 in association with each state. However, each time it is set, for example, it is set in consideration of ambient noise. May be. Thus, the comfort and convenience of the portable terminal device 1 can be further improved by determining the set value according to the situation at that time.
