  In addition, the electronic device 100 may be provided with a light emitting diode, a vibration motor or the like (all not shown) as a notification unit for notifying the user of the information.

[Detection method of abnormal condition of speaker]
Next, a method of detecting an abnormality of the speaker 4 in the electronic device 100 according to the first embodiment will be described.
In the electronic device 100 according to the present embodiment, although the speaker 4 receives the voice reproduction instruction, the electronic device 100 does not emit sound, or the sound is generated but the speaker 4 is abnormal such as smaller than the set volume. Detect and notify the user that the electronic device 100 is in an abnormal state.

The electronic device 100 has a function of periodically calculating the current altitude above sea level from the detection result of the barometric pressure sensor 31 and notifying the user of it.
The air pressure sensor 31 detects the air pressure in the space A as described above, and transmits the detection result to the central control unit 1A. The central control unit 1A calculates the altitude above sea level based on the detection result of the barometric pressure sensor 31, and controls the speaker 4 to reproduce the sound for notification. The voice for notification is for notifying the user of the current altitude above sea level, and is reproduced periodically under the control of the central control unit 1A.

On the other hand, the electronic device 100 has a function of detecting a malfunction of the speaker 4 from the value of the barometric pressure sensor 31 at the time of reproduction of the sound for notification.
The atmospheric pressure sensor 31 can detect the vibration of air in the space A caused by the sound emitted by the speaker 4 as a change in atmospheric pressure in the space A. That is, the input information (pressure data) to the pressure sensor 31 at the time of reproduction of the sound for notification and the input information to the pressure sensor 31 when the sound is reproduced under the same pressure conditions stored in the memory 2 in advance By correlating with the first reference data), it can be determined whether or not the speaker 4 correctly emits a sound. For example, a first correlation coefficient between first reference data (waveform, frequency, sound pressure, etc.) and barometric pressure data at the time of reproduction of notification sound is calculated, and the value of the first correlation coefficient is predetermined. Is outside the range of 1 (outside the first numerical range), that is, when the similarity between the pressure data at the time of reproduction of the notification sound and the first reference data is high, the sound is normally reproduced. I will judge. Conversely, when the first correlation coefficient is within the first numerical range, there is a problem with the speaker 4 such that the audio is not reproduced despite the audio reproduction processing being performed. I will judge.

The correlation coefficient is influenced by the sensitivity of the barometric pressure sensor 31, the design of the housing 10, and the like, and therefore, needs to be adjusted for each electronic device 100. Further, in order to obtain a more accurate correlation, it is necessary to prepare in advance reference data for each reproduced voice, but in this case, if the number of types of reproduced voices is large, the amount of reference data becomes enormous.
Therefore, in order to reduce the amount of reference data, it is desirable to identify the reproduction point that is the feature of the sound for each reproduced sound, and hold the barometric pressure data at a certain sense before and after that as reference data. Or, for example, in the case of limiting the reproduction voice to a reading of the altitude above sea level, such as "It is altitude ○ ○ meters." It is effective to tabulate and hold the time at which the portion starts and store it as barometric pressure data at the time of sound reproduction for a fixed time from that time.

  When the central control unit 1A determines that the electronic device 100 is in an abnormal state, it functions as a notification control unit and notifies that the electronic device 100 is in an abnormal state. For notification of the abnormal state, for example, a warning is displayed on the display unit 8 as a notification unit provided in the main unit unit 100a. Alternatively, in the case where the subunit unit 100b includes a light emitting diode or a vibration motor, it is also possible to control these to perform light emission or vibration according to the abnormal state.

  That is, the electronic device 100 executes the "voice reproduction check process" for detecting a malfunction of the speaker 4 at the start of the reproduction of the voice, separately from the "voice reproduction process" for notifying the user of the altitude above sea level. The two processes are not continuous processes but parallel processes.

  Next, the audio reproduction process and the audio reproduction check process of the electronic device 100 according to the first embodiment will be described using the flowchart of FIG. 5.

When the audio reproduction process is started, the central control unit 1A activates the audio reproduction check process (step S101). The voice reproduction process is periodically performed at regular intervals under the control of the central control unit 1A. Subsequently, the central control unit 1A controls the speaker 4 to reproduce the sound (step S102). Here, the sound notifies the altitude above sea level calculated based on the air pressure detected by the air pressure sensor 31, but it is not necessarily limited to the notification of the sea level altitude.
When the reproduction of the sound is completed, the central control unit 1A ends the sound reproduction process.

  On the other hand, when the voice reproduction check process is activated, the central control unit 1A causes the barometric pressure sensor 31 to detect the barometric pressure for a predetermined time (step S103). The air pressure sensor 31 detects the air pressure of the space A inside the housing 10, but at this time, detects the fluctuation of the air pressure of the space A caused by the sound emitted from the speaker 4 by the process of step S102. The pressure sensor 31 transmits the detected pressure data to the central control unit 1A.

  Subsequently, the central control unit 1A calculates a first correlation coefficient between the barometric pressure data detected in step S103 and the above-described previously sampled first reference data (step S104). Here, for example, numerical values such as waveform, frequency, and sound pressure can be used to calculate the first correlation coefficient between the barometric pressure data and the first reference data.

Subsequently, the central control unit 1A determines whether the first correlation coefficient calculated in step S104 is out of the first numerical range (step S105). When the central control unit 1A determines that the first correlation coefficient is out of the first numerical value range (step S105: YES), the central control unit 1A determines that the speaker 4 normally emits voice and performs the voice reproduction check process. finish.
On the other hand, when central control unit 1A determines that the first correlation coefficient is within the first numerical value range (step S105: NO), it notifies the user that speaker 4 is in an abnormal state (step S106). ). Here, as a notification of the abnormal state of the speaker 4, the central control unit 1A displays a notification to the user on the display unit 8 of the main unit unit 100a or controls a light emitting diode or a vibration motor to notify the user. It is possible to When the notification to the user is completed, the central control unit 1A ends the voice reproduction check process.

  As described above, the electronic device 100 according to the first embodiment includes the housing 10, the speaker 4 (sound output unit) which is disposed inside the housing 10 and outputs sound, and the inside of the housing 10 Is provided with a barometric pressure sensor 31 (barometric pressure detection means) for detecting the barometric pressure, and a central control unit 1A as a state detection control means. Using the barometric pressure data inside the housing 10 detected, the abnormality of the speaker 4 is detected. Therefore, since abnormality detection is performed using the existing barometric pressure sensor 31 and the speaker 4 in the electronic device 100 without adding a configuration such as a microphone, it is possible to detect a defect of the speaker 4 at low cost.

  In the electronic device 100 according to the first embodiment, the central control unit 1A detects barometric pressure data in the housing 10 detected by the barometric pressure sensor 31 when the speaker 4 is operated in the normal state of the speaker 4 As the first reference data, the state of the speaker 4 is detected using the pressure data inside the housing 10 detected by the pressure sensor 31 when the speaker 4 is operated and the first reference data. Further, the central control unit 1A calculates a first correlation coefficient between the barometric pressure data and the first reference data, and when the first correlation coefficient is within the first numerical range, that is, for notification. If the similarity between the pressure data at the time of sound reproduction and the first reference data is high, it is determined that the speaker 4 is abnormal. Therefore, since detection is performed based on highly reliable reference data, the possibility of false detection is low, and an abnormal state can be reliably detected.

  Further, in the electronic device 100 according to the first embodiment, the central control unit 1A includes the display unit 8 as a notification unit, and the central control unit 1A as notification control means detects an abnormality in the speaker 4 In this case, the display unit 8 or the like notifies an abnormality of the speaker 4. Therefore, it is possible to prompt the user to cancel the abnormal state.

Second Embodiment
[Detection method of abnormal condition of speaker and case]
Next, a method of detecting an abnormality in the speaker 4 and an abnormality in the waterproof film 13 in the electronic device 200 according to the second embodiment will be described. FIG. 6 is a block diagram showing a main control configuration of the electronic device 200 according to the second embodiment. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.
Similarly to the first embodiment, the electronic device 200 according to the present embodiment detects an abnormal state of the speaker 4 while the waterproof film 13 is damaged or the like, and the accessory in the sound hole 11 (opening). First detecting the abnormal state in which the waterproof film 13 as the component to be damaged is detected and notifying the user of the abnormal state, and the point of including the central control unit 1B as the state detection control means for executing the process This differs from the electronic device 100 according to the embodiment.

When the waterproof film 13 is damaged, there is a possibility that the internal parts may be broken when water intrudes into the inside of the housing 10. In addition, if dust, water droplets, or the like adhere to the waterproof film 13, problems such as the sound of the speaker 4 becoming difficult to reach the user may occur.
As described above, the barometric pressure sensor 31 detects the vibration of air in the space A caused by the sound emitted by the speaker 4 as a change in the barometric pressure. At this time, although the waterproof film 13 vibrates in accordance with the vibration of air, the manner of the vibration fluctuates depending on the state of the waterproof film 13, so the air pressure of the space A detected by the air pressure sensor 31 fluctuates.

  When no damage or the like occurs in the waterproof film 13, the normal state of the waterproof film 13, a case such as breakage in the waterproof film 13 or a deposit such as water droplets or dust on the waterproof film 13, etc. If the waterproof film 13 is in an abnormal state, the vibration condition of the waterproof film 13 changes in the abnormal state, so the waterproof film 13 does not vibrate sufficiently and the vibration pattern of air in the space A detected by the pressure sensor 31 ( The characteristics of the waveform, frequency, sound pressure, etc.) are different from those in the normal state.

Therefore, the electronic device 200 according to the second embodiment detects that the waterproof film 13 is in the abnormal state by detecting the fluctuation of the value of the air pressure sensor in the abnormal state of the waterproof film 13.
That is, in the electronic device 200, when the speaker 4 is in the abnormal state and the waterproof film 13 is in the normal state, the air pressure detected by the air pressure sensor 31 at the time of emitting the sound by the speaker 4 is the second reference data, the speaker When 4 is in the normal state and the waterproof film 13 is in the abnormal state, the third reference data of the air pressure detected by the air pressure sensor 31 when sound is emitted by the speaker 4, the speaker 4 and the waterproof film 13 are in the normal state In this case, the atmospheric pressure detected by the atmospheric pressure sensor 31 when the sound from the speaker 4 is emitted is held in the memory 2 of the fourth reference data.
The central control unit 1B sends the input information (pressure data) to the pressure sensor 31 at the time of reproduction of the sound for notification and the pressure sensor 31 when the sound is reproduced under the same pressure conditions stored in advance in the memory 2 The abnormal state of the speaker 4 and the waterproof film 13 is detected by correlating with the input information (second reference data, third reference data, fourth reference data) of For example, the fourth correlation coefficient between the fourth reference data and the barometric pressure data is calculated, and the value of the fourth correlation coefficient is out of the predetermined range (out of the fourth numerical range), that is, the fourth reference data If the similarity between the pressure data and the pressure data is high, it can be determined that the speaker 4 and the waterproof film 13 are in the normal state. When the second correlation coefficient is out of the predetermined range (outside the second numerical range), the speaker 4 is in an abnormal state because the similarity between the second reference data and the barometric pressure data is high. If the third correlation coefficient is out of the predetermined range (outside the third numerical range), the waterproof film 13 is in an abnormal state because the similarity between the third reference data and the atmospheric pressure data is high. It is suggested.

  That is, the electronic device 200 according to the second embodiment detects an abnormal state of the speaker 4 or the waterproof film 13 separately from the "audio reproduction process" of notifying the user of the altitude above sea level. Execute "Process". The two processes are not continuous processes but parallel processes.

  Next, the sound reproduction processing and sound reproduction / waterproof film state check processing of the electronic device 200 according to the second embodiment will be described using the flowchart of FIG. 7.

When the voice reproduction process is started, the central control unit 1B activates the voice reproduction / waterproof film condition check process (step S201). The voice reproduction process is periodically performed at regular intervals under the control of the central control unit 1B. Subsequently, the central control unit 1B controls the speaker 4 to reproduce the sound (step S202).
When the reproduction of the sound is completed, the central control unit 1B ends the sound reproduction process.

  On the other hand, when the voice reproduction / waterproof film state check process is activated, the central control unit 1B causes the barometric pressure sensor 31 to detect the barometric pressure only for a predetermined time (step S203). The pressure sensor 31 transmits the detected pressure data to the central control unit 1B.

  Subsequently, in step S203, the central control unit 1B uses the previously sampled second reference data, third reference data, and fourth reference data to detect the detected barometric pressure data and the second barometric data. The second correlation coefficient with the reference data, the third correlation coefficient with the barometric pressure data and the third reference data, and the fourth correlation coefficient with the barometric pressure data and the fourth reference data are calculated (step S204) ). Here, for the calculation of the second correlation coefficient, the third correlation coefficient, and the fourth correlation coefficient, for example, numerical values such as a waveform, a frequency, and a sound pressure can be used.

  Subsequently, the central control unit 1B determines whether the fourth correlation coefficient calculated in step S204 is out of the fourth numerical range (step S205). If the central control unit 1B determines that the fourth correlation coefficient is within the fourth numerical range (step S205: NO), the central control unit 1B proceeds to step S206. When the central control unit 1B determines that the fourth correlation coefficient is out of the fourth numerical value range (step S205: YES), it determines that the speaker 4 and the case 10 are in a normal state, and reproduces sound and waterproofs The film state check process is ended.

In step S206, the central control unit 1B determines whether the second correlation coefficient calculated in step S204 is outside the second numerical value range. When the central control unit 1B determines that the second correlation coefficient is out of the second numerical range (YES in step S206), the central control unit 1B determines that the speaker 4 is in an abnormal state, and gives the user an abnormal state of the speaker 4 The notification is given by the display unit 8 (step S207), and the voice reproduction / waterproof film state check process is ended.
If the central control unit 1B determines that the second correlation coefficient is within the second numerical range (step S206: NO), the central control unit 1B proceeds to step S208.

In step S208, the central control unit 1B determines whether the third correlation coefficient calculated in step S204 is out of the third numerical range. If the central control unit 1B determines that the third correlation coefficient is out of the third numerical range (step S208: YES), the central control unit 1B determines that the waterproof film 13 is in an abnormal state, The state is notified by the display unit 8 (step S209), and the voice reproduction / waterproof film state check process is ended.
When the central control unit 1B determines that the third correlation coefficient is within the third numerical range (step S208: NO), the central control unit 1B determines that the speaker 4 and the waterproof film 13 are in an abnormal state. And the abnormal state of the waterproof film 13 is notified by the display unit 8 (step S210), and the sound reproduction / waterproof film condition check process is ended.

  As described above, the electronic device 200 according to the second embodiment includes the sound hole 11 as the opening and the waterproof film 13 as a component attached to the opening, and the central control unit 1B is a speaker The state of the speaker 4 and the waterproof film 13 is detected using the pressure data inside the housing 10 detected by the pressure sensor 31 when the pressure sensor 4 is operated. Therefore, since the state detection is performed using the existing air pressure sensor 31 and the speaker 4 in the electronic device 200, it is possible to detect a failure of the speaker 4 and the waterproof film 13 at low cost.

  In the electronic device 200 according to the second embodiment, the central control unit 1B detects an air pressure sensor when the speaker 4 is operated in a state where the speaker 4 is abnormal and the waterproof film 13 is normal. The air pressure data in the inside of the case 10 is the second reference data, there is an abnormality in the waterproof film 13, and in the normal state of the speaker 4, the inside of the case 10 detected by the air pressure sensor 31 when the speaker 4 is operated The air pressure data of is used as the third reference data, and the states of the speaker 4 and the waterproof film 13 are detected using the air pressure data and the second reference data and the third reference data. Further, the central control unit 1B calculates a second correlation coefficient between the barometric pressure data and the second reference data, and when the second correlation coefficient is out of the second numerical range, the speaker 4 is abnormal. I judge that there is. Further, the central control unit 1B calculates a third correlation coefficient between the barometric pressure data and the third reference data, and when the third correlation coefficient is out of the third numerical range, the waterproof film 13 is abnormal. Judge that there is. Therefore, the abnormal state of the speaker 4 and the waterproof film 13 can be separately detected.

  Further, in the electronic device 200 according to the second embodiment, the central control unit 1B includes the display unit 8 as a notification unit, and the central control unit 1B as a notification control unit includes at least the speaker 4 and the waterproof film 13. When one abnormality is detected, the display unit 8 or the like notifies the abnormality. Therefore, it is possible to prompt the user to cancel the abnormal state.

In the above embodiment, although the voice reproduction / waterproof film state check process is performed using the second correlation coefficient, the third correlation coefficient, and the fourth correlation coefficient, the present invention is not limited to this. .
For example, in the case where the electronic device 200 holds the air pressure detected by the air pressure sensor 31 when the speaker 4 emits a sound when the speaker 4 and the waterproof film 13 are in an abnormal state, central control is performed. When the fifth correlation coefficient is outside the predetermined range (outside the fifth numerical range), that is, when the similarity between the fifth reference data and the barometric pressure data is high, the unit 1B is configured to use the speaker 4 and the waterproof film. It is suggested that 13 is an abnormal state. Therefore, by appropriately combining the second correlation coefficient, the third correlation coefficient, the fourth correlation coefficient, and the fifth correlation coefficient, it is possible to perform the voice reproduction / waterproof film state check process.

  In the above embodiment, the correlation coefficient is used as a method of determining the similarity between the barometric pressure data and the reference data, but a method other than the correlation coefficient may be used.
