底鼓里可能会有一个鼓枕靠着鼓皮放在鼓腔中。
The kick drum may have a pillow resting up against the inside bass drum head .
著名的击鼓是由交替按贴在鼓皮的控制反弹努力。
The famous drum roll is produced by alternatively pressing the sticks on the drum head striving for a controlled rebound.
喇叭芯、锣鼓皮、和吉他弦的震动，都是震动产生了声音的绝好例子。
The motions of a loudspeaker cone, drumhead and guitar string are good examples of vibration that cause sound.
另外还大量生产黄牛鼓皮、水牛鼓皮、羊皮及聚酯鼓皮等各种鼓类配件。
In addition we are able to product scalper drum skin, buffalo drum skin, sheepskin, and polyester drum skin and all kinds of drum fittings.
如果底鼓前面没有鼓皮，那么就把麦克固定在鼓腔内距踩锤击打位置1英尺的位置。
If there's no front kick drum head, position the mic inside the bass drum about a foot back from the point where the beater hits.
而根据牛顿第三定律，鼓皮会施予鼓棍一个方向相反但数值相等的力，并传到我的手中！
Moreover, according to the Newton's Third Law, the snare drum and my hand are action and reaction pair. Hence, a force which is equal in magnitude but opposite in direction would act on me.
考虑到落地桶鼓是在标准垂直方向上：如用木地板，当鼓手击鼓，下面的鼓皮也要跟随着震动。
Consider a floor Tom mounted in a standard vertical orientation: With a hardwood floor, when the player hits the drum the bottom head vibrates sympathetically.
这个直接向着地板去的声波将被反弹上来并且会对底面鼓皮的震动造成相消或加重某些频率的影响。
With the tom set up vertically, sound waves hit the floor and bounce back into the bottom head. Angling a tom slightly causes sound waves to scatter, and diffuses them.
他把低音单元按“口味”放置在鼓皮外低频比较有密度的地方—简单的移动直到你听到最自然的低频为止。
He positions the woofer to taste on the outside head in which the low frequencies are thick - simply move around until you hear the most natural low frequencies.
当使用多个麦克时，我们要把每一个麦克按照固定的轨迹移动来调整距鼓皮的距离，以防止它们与鼓腔内的麦克产生相位上的偏差。
When using multiple mics, though, slip the track for any mic set at some distance from the head so that its phase lines up with the dynamic mic inside the kick.
