Technical Field

[0001] The utility model relates to the technical field related to bone conduction hearing aids, in particular to a semi-in-ear open bone conduction hearing aid. Background Art

[0002] Common bone conduction hearing aids on the market usually place the bone conduction vibrator contact part on the temporal bone, and transmit sound through the vibration of the temporal bone. There are problems such as external sound leakage and more vibration discomfort. At the same time, there is also a problem that the effective volume is too small when the vibrator power is the same. In hearing aid applications, due to external sound leakage and insufficient sound volume, the gain of bone conduction hearing aids is generally small, and the hearing aid effect is poor. For this reason, we propose a semi-in-ear open bone conduction hearing aid. Utility Model Content
