Abstract: The present invention discloses an audio device output energy control method for protecting hearing, the method including: step S1, obtaining energy or pressure at a speaker or at any point in a sound field from the speaker to a tympanic membrane by means of calculation or measurement, which serves as the energy or pressure at the tympanic membrane or cochlea of a user after compensation or calculation; step S2, calculating a cumulative hearing loss value according to the energy or pressure at the tympanic membrane or cochlea of the user, or calculating cumulative energy at any point in the sound field from the speaker to the tympanic membrane according to the energy or pressure at that location, and then equivalently calculating a cumulative hearing loss value at the tympanic membrane or cochlea of the user; step S3, comparing the cumulative hearing loss value with a preset hearing loss threshold, and performing step S4 if the cumulative hearing loss value reaches the hearing loss threshold; and step S4, reducing a volume of the audio device. The present invention can monitor the energy at the tympanic membrane or cochlea of the user in real time and adjust the output energy of the audio device in time, thus realizing hearing protection.

Abstract: A sound privacy protection device is provided, including: a wearable structure configured to be worn at an ear; and a mount structure connected to the wearable structure, where the mount structure is provided with at least one sound generating unit; the mount structure is provided with at least one front vent for guiding the sound generating unit; and an acoustic outlet end of the front vent is arranged close to an ear canal entrance point (EEP). According to the present invention, the front vent and the reverse vent are both arranged on the mount structure, and the front vent and the reverse vent are positioned at the set points through the wearable structure, such that the sound waves of the reverse vent and the front vent cancel each other out in the afar sound fields, thereby achieving the purpose of sound elimination, preventing the surroundings from hearing the sound emitted by the device and protecting privacy.
