可以理解，在其他实施例中，振动反馈模组20可为应变片或其他压力感应元件。
如此，振动反馈模组20通过压力感应单元24的力敏电阻部242在压力作用下发生形变，控制件28依据力敏电阻部242因形变改变的电阻值，向压电振动单元26施加预设电压，以使压电振动单元26可依据压力大小进行对应的振动反馈。进一步地，通过压电振动单元26与收容部222之间设有间隙，以防止压电振动单元26振动时与基板22产生共振，进而产生噪音，同时相较于压电振动单元26与收容部222直接接触，压电振动单元26的振动效果明显，响应速度快，易被用户感知。

进一步地，第一电路板264设于弹性补强件266和压电件262之间，压电件262设于第一电路板264且第一电路板264与压电件262电连接。

在一实施例中，胶框为光敏胶，呈方框状。
请参见图6和图7，在一实施例中，压力感应单元24包括相连接的支撑板244和第二电路板246，支撑板244设于收容部222，力敏电阻部242设于支撑板244相背于基板22的一侧，力敏电阻部242与第二电路板246电连接。
