The invention discloses a bone conduction seat headrest. The bone conduction seat headrest body is composed of a headrest skin and a headrest inner core. A novel electric vibration unit is installed on the side, opposite to the head of a human body, of the bone conduction seat headrest body. The novel electric vibration unit is composed of at least one electric vibration device and a signal filtering mechanism matching the electric vibration device. The electric vibration device is arranged on the signal filtering mechanism and faces the head of the human body; the signal filtering mechanism is fixedly connected with the bone conduction seat headrest body; the novel electric vibration unit matches the bone conduction seat headrest body. According to the invention, the vibration energy in the product is selectively filtered for the first time; therefore, the sound leakage phenomenon generated by the bone conduction seat headrest body can be reduced under the condition that the vibrationenergy output of the electric vibration device to the human head is not reduced; therefore, the auditory feeling is not changed, the problem that the auditory feeling of a user is deteriorated afterthe vibration power of the electric vibration device is directly reduced in an existing sound leakage solution is solved, and the market prospect is greatly expanded.
一种骨传导座椅头枕,由头枕蒙皮和头枕内芯构成该骨传导座椅头枕主体,该骨传导座椅头枕主体上相对人体头部一侧安装有新型电振动单元,该新型电振动单元至少由一个电振动器件和与其匹配的信号过滤机构构成,其中该电振动器件安装在信号过滤机构上朝向人体头部位置,该信号过滤机构与本骨传导座椅头枕主体固定连接,该新型电振动单元与骨传导座椅头枕主体相匹配,本专利首次使此类产品内部的振动能量被选择性过滤,因此可以在不减小电振动器件对人头部振动能量输出的情况下降低骨传导座椅头枕主体产生的漏音现象,从而使听觉感受不变,克服了现有漏音解决方案直接降低电振动器件振动功率后会使用户听觉感受劣化问题,使市场前景极大广展。
