Electronic device having a waterproof structure

An electronic device comprising:

• a housing having an opening, the opening having a structure to be waterproofed with a waterproof member comprising a waterproof membrane that partitions an internal space and an external space of the housing;
• a data output unit arranged in the housing, wherein the data output unit detects a change depending on a state of the waterproof member and outputs data caused by the detection;
• a sound outputting unit arranged in the housing;
• a processor;
• and
• a storage unit which stores a program to be executed by the processor,
• wherein the processor performs, in accordance with the program stored in the storage unit,
• a state detection process for detecting, as an abnormal state of the waterproof member, damage to the waterproof membrane or contamination of the waterproof membrane with a foreign substance based on the data outputted by the data output unit, and
• a notification control process of instructing a notifying unit to notify a user of the damage to the waterproof membrane or the contamination of the waterproof membrane with the foreign substance,
• wherein the data output unit comprises an atmospheric-pressure detecting unit, arranged in the housing, which determines an atmospheric pressure in the internal space of the housing, and outputs the determined atmospheric pressure,
• wherein the waterproof membrane vibrates in response to a sound outputted from the sound outputting unit, and
• wherein the state detection process includes detecting the abnormal state of the waterproof membrane based on data on the atmospheric pressure in the internal space of the housing determined by the atmospheric-pressure detecting unit at the time when the sound outputting unit is outputting a sound, the atmospheric pressure varying in response to vibration of the waterproof membrane,
• wherein the electronic device has (i) first reference data that is data on an atmospheric pressure determined by the atmospheric-pressure detecting unit at the time when the sound outputting unit is outputting a sound in a state where the waterproof membrane is damaged and (ii) second reference data that is data on an atmospheric pressure determined by the atmospheric-pressure detecting unit at the time when the sound outputting unit is outputting a sound in a state where the waterproof membrane is contaminated with the foreign substance, and
• wherein the state detection process includes:
• comparing the data on the atmospheric pressure determined by the atmospheric-pressure detecting unit with each of the first reference data and the second reference data, and
• determining whether the waterproof membrane is damaged or contaminated with the foreign substance based on similarity between the data on the atmospheric pressure determined by the atmospheric-pressure detecting unit and each of the first reference data and the second reference data.
