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

[How to detect abnormal speaker condition]
Next, a method of detecting an abnormality of the speaker 4 in the electronic device 100 according to the first embodiment will be described.
The electronic device 100 according to the present embodiment has an abnormality in the speaker 4, such as that the speaker 4 does not emit sound even though it has been instructed to reproduce sound, or that the speaker 4 emits sound but is smaller than the set volume. Detects and notifies 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.
As described above, the atmospheric pressure sensor 31 detects the atmospheric pressure in the space A 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, controls the speaker 4, and reproduces the voice for notification. The notification voice notifies the user of the current altitude above sea level, and is periodically played back under the control of the central control unit 1A.

On the other hand, the electronic device 100 has a function of detecting a defect of the speaker 4 from the value of the barometric pressure sensor 31 at the time of reproducing the voice for notification.
The barometric 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 the barometric pressure in the space A. That is, the input information (atmospheric pressure data) to the barometric pressure sensor 31 at the time of reproducing the sound for notification and the input information to the barometric pressure sensor 31 when the sound is reproduced under the same barometric pressure condition stored in the memory 2 in advance (that is, By correlating with the first reference data), it can be determined whether or not the speaker 4 is emitting sound correctly. For example, the first correlation coefficient between the first reference data (waveform, frequency, sound pressure, etc.) and the barometric pressure data at the time of reproducing the sound for notification is calculated, and the value of the first correlation coefficient is predetermined. If it is out of the range of (outside the first numerical range), that is, if the barometric pressure data at the time of playing the notification sound and the first reference data have a high similarity, the sound is played normally. Judge. On the contrary, when the first correlation coefficient is within the first numerical range, there is a problem with the speaker 4, such as no sound being reproduced even though the sound reproduction processing is being performed. Judge.

Since the correlation coefficient is affected by the sensitivity of the barometric pressure sensor 31, the design of the housing 10, and the like, it is necessary to adjust it for each electronic device 100. Further, in order to obtain a more accurate correlation, it is necessary to prepare advance reference data for each reproduced voice, but in this case, if there are many types of reproduced voices, the amount of reference data becomes enormous.
Therefore, in order to suppress the amount of reference data, it is desirable to specify a reproduction point that is a feature of the reproduction sound for each reproduction sound, and to hold the barometric pressure data in a certain feeling before and after that as the reference data. Or, for example, if you want to limit the playback voice to reading aloud the altitude above sea level, such as "Altitude XX meters.", "It is meters. It is effective to create a table and hold the time when the part starts, and keep it as the barometric pressure data at the time of voice reproduction for a certain period 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 means and notifies that the electronic device 100 is in an abnormal state. To notify that an abnormal state is present, for example, a warning is displayed on the display unit 8 as a notification unit provided in the main unit unit 100a. Alternatively, when the subunit unit 100b includes a light emitting diode and a vibration motor, it is also possible to control these to emit light or vibrate according to an abnormal state.

That is, the electronic device 100 executes a "voice reproduction check process" for detecting a defect in the speaker 4 at the start of audio reproduction, in addition to the "voice reproduction process" for notifying the user of the altitude above sea level. Both processes are not continuous processes but parallel processes.

Next, the audio reproduction processing and the audio reproduction check processing of the electronic device 100 according to the first embodiment will be described with reference to the flowchart of FIG.

When the central control unit 1A starts the voice reproduction processing, the voice reproduction check processing is started (step S101). The audio reproduction process is periodically executed 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 voice is to notify the altitude above sea level calculated based on the atmospheric pressure detected by the atmospheric pressure sensor 31, but it is not necessarily limited to the notification of the altitude above sea level.
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 atmospheric pressure sensor 31 to detect the atmospheric pressure for a predetermined time (step S103). The atmospheric pressure sensor 31 detects the atmospheric pressure in the space A inside the housing 10, and at this time, detects the change in the atmospheric pressure in the space A caused by the sound emitted from the speaker 4 by the process of step S102. The barometric pressure sensor 31 transmits the detected barometric 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-mentioned pre-sampled first reference data (step S104). Here, for the calculation of the first correlation coefficient between the barometric pressure data and the first reference data, for example, numerical values such as a waveform, a frequency, and a sound pressure can be used.

Subsequently, the central control unit 1A determines whether or not the first correlation coefficient calculated in step S104 is outside the first numerical range (step S105). When the central control unit 1A determines that the first correlation coefficient is out of the first numerical range (step S105: YES), the central control unit 1A determines that the speaker 4 is normally emitting sound, and performs a sound reproduction check process. finish.
On the other hand, when the central control unit 1A determines that the first correlation coefficient is within the first numerical range (step S105: NO), the central control unit 1A notifies the user that the speaker 4 is in an abnormal state (step S106). ). Here, as a notification of an 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 do. When the central control unit 1A completes the notification to the user, the voice reproduction check process ends.

As described above, the electronic device 100 according to the first embodiment is arranged inside the housing 10, the speaker 4 (sound output means) that outputs sound, and the inside of the housing 10. A barometric pressure sensor 31 (barometric pressure detecting means) for detecting barometric pressure and a central control unit 1A as a state detection control means are provided, and the central control unit 1A is a barometric pressure sensor 31 when the speaker 4 is operated. The abnormality of the speaker 4 is detected by using the atmospheric pressure data inside the housing 10 detected by. Therefore, since the abnormality is detected by using the existing barometric pressure sensor 31 and the speaker 4 in the electronic device 100 without adding the configuration of the microphone or the like, it is possible to detect the defect of the speaker 4 at low cost.

Further, in the electronic device 100 according to the first embodiment, the central control unit 1A has the barometric pressure data inside the housing 10 detected by the barometric pressure sensor 31 when the speaker 4 is operated in a normal state. Is used as the first reference data, and the state of the speaker 4 is detected by using the barometric pressure data inside the housing 10 detected by the barometric 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 barometric pressure data at the time of reproducing the sound and the first reference data have a high similarity, it is determined that the speaker 4 has an abnormality. Therefore, since the detection is performed based on highly reliable reference data, the possibility of false detection is low, and the abnormal state can be reliably detected.

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

<Second embodiment>
[Method of detecting abnormal state of speaker and housing]
Next, a method for 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. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
Similar 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 and is attached to the sound hole 11 (opening). The first point is that the waterproof film 13 as a component to be damaged detects an abnormal state and notifies the user of the abnormal state, and the central control unit 1B as a state detection control means for executing the process is provided. It is different from the electronic device 100 according to the embodiment.

If the waterproof film 13 is damaged, internal parts may be damaged if water enters the inside of the housing 10. Further, if dust, water droplets, or the like adhere to the waterproof film 13, a problem such as a dial tone from the speaker 4 becoming difficult to reach the user occurs.
As described above, the atmospheric pressure sensor 31 detects the vibration of air in the space A caused by the dial tone emitted by the speaker 4 as a change in atmospheric pressure. At this time, the waterproof film 13 vibrates with the vibration of the air, but the way of vibration changes depending on the state of the waterproof film 13, so that the air pressure in the space A detected by the atmospheric pressure sensor 31 fluctuates.

The case where the waterproof film 13 is not damaged is the normal state of the waterproof film 13, the case where the waterproof film 13 is damaged such as torn, or the case where the waterproof film 13 has deposits such as water droplets and dust. When is set to an abnormal state of the waterproof film 13, the vibration condition of the waterproof film 13 changes in the abnormal state, so that the waterproof film 13 does not vibrate sufficiently, and the vibration pattern of air in the space A detected by the pressure sensor 31 ( (Characteristics such as waveform, frequency, sound pressure, etc.) will be different from 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 barometric pressure sensor in the abnormal state of the waterproof film 13.
That is, in the electronic device 200, when the speaker 4 is in an abnormal state and the waterproof film 13 is in a normal state, the atmospheric pressure detected by the atmospheric pressure sensor 31 when the sound is emitted by the speaker 4 is used as the second reference data, the speaker. When 4 is in a normal state and the waterproof film 13 is in an abnormal state, the atmospheric pressure detected by the atmospheric pressure sensor 31 when the speaker 4 emits a sound is the third reference data, and the speaker 4 and the waterproof film 13 are in a normal state. In this case, the atmospheric pressure detected by the atmospheric pressure sensor 31 when the sound is emitted from the speaker 4 is held in the memory 2 as the fourth reference data.
The central control unit 1B sends the input information (atmospheric pressure data) to the barometric pressure sensor 31 at the time of reproducing the sound for notification and the barometric pressure sensor 31 when the sound is reproduced under the same pressure conditions stored in the memory 2 in advance. By correlating with the input information (second reference data, third reference data, fourth reference data), the abnormal state of the speaker 4 and the waterproof film 13 is detected. 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 (outside the fourth numerical range), that is, the fourth reference data. When the similarity between the barometric pressure data and the barometric pressure data is high, it can be determined that the speaker 4 and the waterproof film 13 are in a normal state. Further, 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. When the third correlation coefficient is out of the predetermined range (outside the third numerical value range), the waterproof film 13 may be in an abnormal state because the similarity between the third reference data and the barometric pressure data is high. It is suggested.

That is, the electronic device 200 according to the second embodiment has a "voice reproduction / waterproof film state check" that detects an abnormal state of the speaker 4 or the waterproof film 13 in addition to the "voice reproduction process" that notifies the user of the altitude above sea level. Execute "Process". Both processes are not continuous processes but parallel processes.

Next, the audio reproduction process and the audio reproduction / waterproof film state check process of the electronic device 200 according to the second embodiment will be described with reference to the flowchart of FIG. 7.

When the central control unit 1B starts the audio reproduction process, the audio reproduction / waterproof film state check process is activated (step S201). The audio reproduction process is periodically executed 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 audio reproduction is completed, the central control unit 1B ends the audio reproduction process.

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

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

Subsequently, the central control unit 1B determines whether or not the fourth correlation coefficient calculated in step S204 is outside the fourth numerical range (step S205). When the central control unit 1B determines that the fourth correlation coefficient is within the fourth numerical range (step S205: NO), the process proceeds to step S206. When the central control unit 1B determines that the fourth correlation coefficient is out of the fourth numerical range (step S205: YES), the central control unit 1B determines that the speaker 4 and the housing 10 are in a normal state, and reproduces and waterproofs the sound. The film condition check process is completed.

In step S206, the central control unit 1B determines whether or not the second correlation coefficient calculated in step S204 is outside the second numerical range. When the central control unit 1B determines that the second correlation coefficient is out of the second numerical range (step S206: YES), it determines that the speaker 4 is in an abnormal state, and informs the user of the abnormal state of the speaker 4. Notification is given by the display unit 8 (step S207), and the voice reproduction / waterproof film state check process is completed.
When the central control unit 1B determines that the second correlation coefficient is within the second numerical range (step S206: NO), the process proceeds to step S208.

In step S208, the central control unit 1B determines whether or not the third correlation coefficient calculated in step S204 is outside the third numerical range. When the central control unit 1B determines that the third correlation coefficient is out of the third numerical range (step S208: YES), it determines that the waterproof film 13 is in an abnormal state, and tells the user that the waterproof film 13 is abnormal. The status is notified by the display unit 8 (step S209), and the voice reproduction / waterproof film status check process is completed.
When the central control unit 1B determines that the third correlation coefficient is within the third numerical range (step S208: NO), it determines that the speaker 4 and the waterproof film 13 are in an abnormal state, and tells the user the speaker 4 The display unit 8 notifies the abnormal state of the waterproof film 13 (step S210), and the sound reproduction / waterproof film state check process is completed.

As described above, the electronic device 200 according to the second embodiment includes a sound hole 11 as an opening and a 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 by using the atmospheric pressure data inside the housing 10 detected by the atmospheric pressure sensor 31 when the 4 is operated. Therefore, since the state is detected by using the existing barometric pressure sensor 31 and the speaker 4 in the electronic device 200, it is possible to detect the defect of the speaker 4 and the waterproof film 13 at low cost.

Further, in the electronic device 200 according to the second embodiment, the central control unit 1B detects the pressure sensor when the speaker 4 is operated in a state where the speaker 4 has an abnormality and the waterproof film 13 is normal. The pressure data inside the housing 10 is the second reference data, and the inside of the housing 10 is detected by the pressure sensor 31 when the speaker 4 is operated in a state where the waterproof film 13 has an abnormality and the speaker 4 is normal. The state of the speaker 4 and the waterproof film 13 is detected by using the pressure data as the third reference data, the pressure data, 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 outside the second numerical range, the speaker 4 has an abnormality. 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 outside 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 detected individually.

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

In the above embodiment, the voice reproduction / waterproof film state check process is performed using the second correlation coefficient, the third correlation coefficient, and the fourth correlation coefficient, but the present invention is not limited to this. ..
For example, when the electronic device 200 holds the atmospheric pressure detected by the atmospheric pressure sensor 31 when the speaker 4 emits a sound when the speaker 4 and the waterproof film 13 are in an abnormal state, the central control is performed. Part 1B includes the speaker 4 and the waterproof film when the fifth correlation coefficient is out of 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. It is suggested that 13 is in an abnormal state. Therefore, it is possible to perform the voice reproduction / waterproof film state check process by appropriately combining the second correlation coefficient, the third correlation coefficient, the fourth correlation coefficient, and the fifth correlation coefficient.

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

Further, in the above embodiment, the film as a component attached to the sound hole 11 (opening) is a waterproof film 13 having a waterproof structure, but it is not always necessary to have a waterproof structure.
