A japan team has built a number of " melody roads " . it uses cars as tuning forks to play music as they travel 日前，来自日本北海道工业研究所的工程师们修建了几条神奇的“音乐公路” 。当汽车驶入的时候，就如同音叉一样，可以使公路发出悦耳动听的声音。
If you have three tuning forks , each one of the second two tuned to a lesser resonant harmonic ( slower vibratory frequency ) than the one before it 如果你有3个音叉，和它之前的第一个相比，其它两个每一个就会以一个比较低的频率谐振（比较低的振动频率） 。
The slower vibration of the last tuning fork , is a perfect image of the vibration of the higher tuning fork , but the rate of its vibration per unit of time has been slowed down 最后音叉的较低的振动是更高级音叉振动的一幅完美的图像，只是它的每个时间单元的振动速率已经减缓下来。
Crystals varied in patterns or grid - sizes - color combinations - and tones . crystals follow harmonic frequencies and could be used with an instrument that looks like a tuning fork 水晶有不同的形状、晶格、大小、颜色组合以及不同音调。水晶随着调和的频率振动和能够视为调音叉子一样的工具来使用。
This paper aims to finish the electronic interface circuit of the tuning fork micromechanical gyroscope detected by capacitance to ensure the vibrating of the gyroscope and to detect and process the signals 本文针对音叉电容式微机械陀螺的接口电路设计、稳幅谐振、微弱信号检测和处理等问题开展研究。
Bell spent his evening experimenting with tuning forks ( forkshaped pieces of metal which always produce the same musical note and which are used to tune pianos ) , metal springs , and magneto batteries 贝尔整晚用调音叉（叉状的金属条，它可以产生相同的音符，并且可以用来调钢琴、金属线、磁电池进行试验。
They act as an intermediary transducer , much as a tuning fork which when struck , and then being brought into proximity of another tuning fork , will start the second fork to begin vibrating also 他们担当了中间媒介变换器角色，非常像受了敲击的音叉，紧接着就引起了另一个音叉的共鸣，就会引起第二个音叉也同样开始振动。
3 . the sensing circuit tuning fork micromechanical gyroscope is designed . as for the detecting circuit of the capacitances , the " charge sense " circuit are improved , and the detecting bridge is designed 电容检测电路采用电荷放大器方案，并且对其进行了改进；对电容检测电路的输出信号进行了分析，设计了信号检测电路，有效的分离出了输入角速度。
A quartz tuning fork gyro uses a double - ended tuning fork to sense the angle rate . it is widely applied in low precision inertia measure field , because of its tiny bulk , low power consumption and high reliability 音叉式石英微陀螺是一种以双端音叉作为角速度敏感元件的振动式微机械陀螺,它具有体积小、功耗低、可靠性高等优点,在低精度惯性测量领域中有广泛的应用。
Batteries provide the power to turn the hands or fire the liquid - crystal display , but quartz oscillators ? essentially , vibrating tuning forks ? provide the chronometers ' steady beat . “ even a cheap quartz watch is accurate to one or two seconds a month , ” says lou m ?中的电池负责提供能量，带动指针或点亮液晶显示器，而石英震?器（也就是振动的音叉）则负责为计时器提供稳定的节拍。
