👉 Ringtone fumes refer to the unpleasant odors that can emanate from smartphones when their built-in ringtone is playing, often due to the degradation of the speaker or the accumulation of dust and dirt inside the device. This phenomenon occurs because the ringtone, typically a short, high-pitched sound, can cause friction and vibrations within the speaker's internal components, leading to the release of volatile organic compounds (VOCs) and other airborne particles. These fumes can be particularly noticeable in enclosed spaces or when the phone is used frequently, affecting not only the air quality but also potentially causing discomfort or irritation to those nearby.
