Abstract

The present application provides an acoustic device and an ear hook hearing aid device. The acoustic device is configured to assist a user in acquiring sounds arriving from a neighborhood along a target direction. The acoustic sensor module collects external sound from outside the acoustic device and internal sound emitted from the position of the speaker module to generate sensor signals; the signal processing circuit performs a target operation based on the sensor signals to generate a drive signal; and the speaker module receives the drive signal and outputs speaker sound that satisfies a target sensitivity with respect to the surrounding sound. The target sensitivity is such that, within a preset auditory frequency range, the sensitivity distribution of the acoustic device to external sound is directional and has a maximum value in the target direction, and the speaker sensitivity to internal sound is less than 3 dB. The acoustic device not only achieves good spatial directivity but also effectively suppresses howling, providing the user with an improved acoustic experience.
