Abstract
A vibrator group manufacturing method includes measuring resonance frequencies of first to n-th vibrators with respect to a vibrator group including the first to n-th vibrators arranged in a matrix, n being an integer of 2 or greater, and storing attachment information of the vibrator group in a storage device, the attachment information including identification information imparted to the vibrator group, pieces of first to n-th positional information indicating positions of the first to n-th vibrators, and pieces of first to n-th characteristic information based on measurement results of the resonance frequencies of the first to n-th vibrators.
Claims9
A vibrator group manufacturing method comprising:
- measuring resonance frequencies of first to n-th vibrators arranged in a matrix with respect to a vibrator group including the first to n-th vibrators, n being an integer of 2 or greater;
- and
- storing attachment information of the vibrator group in a storage device, the attachment information including identification information imparted to the vibrator group, pieces of first to n-th positional information indicating positions of the first to n-th vibrators, and pieces of first to n-th characteristic information based on measurement results of the resonance frequencies of the first to n-th vibrators.
An oscillator manufacturing method comprising:
- preparing a vibrator group including first to n-th vibrators arranged in a matrix, and first to n-th integrated circuit devices;
- acquiring attachment information of the vibrator group which includes pieces of first to n-th positional information indicating positions of the first to n-th vibrators and pieces of first to n-th characteristic information based on measurement results of resonance frequencies of the first to n-th vibrators;
- selecting the k-th vibrator from the vibrator group to integrate the k-th vibrator and the k-th integrated circuit device with each other, k being an integer of 1 to n;
- and
- selecting the k-th characteristic information based on the k-th positional information to perform frequency adjustment of an output signal of the k-th integrated circuit device based on the k-th characteristic information.
