Description

TECHNICAL FIELD

[0001] The utility model relates to sensor technical field, especially a piezoelectric ceramic pickup sensor convenient to installation. BACKGROUND

[0002] The piezoelectric ceramic pickup sensor is a device that can convert sound signals into electrical signals, and it mainly uses the piezoelectric effect to achieve this function. Piezoelectric ceramic is a special ceramic material that changes its internal structure when subjected to external forces, resulting in the movement of electric charge distribution. When pressure is applied to the piezoelectric ceramic, a voltage is generated between its two poles, which is directly proportional to the size of the pressure. Therefore, sound information can be obtained by measuring the voltage. This pickup sensor has the characteristics of small size, light weight, high sensitivity, and strong anti-interference ability, so it has been widely used in many fields. For example, in a smartphone, the piezoelectric ceramic pickup can capture the user's voice input; in a voice-controlled home system, it can be used as a key component for voice recognition; and in the medical field, it can be used to detect and analyze physiological signals in the human body.

[0003] The piezoelectric ceramic pickup sensor is a new type of sensor with high sensitivity and wide frequency response range. However, there are some problems in its practical application, such as difficult installation and short service life. Therefore, a piezoelectric ceramic pickup sensor that is easy to install is needed to quickly install the piezoelectric ceramic pickup sensor. The existing piezoelectric ceramic pickup sensor that is easy to install usually uses a direct glue bonding method during installation, which can cause the piezoelectric ceramic pickup sensor to be fixed complicatedly and not easily disassembled, resulting in the piezoelectric ceramic sensor being damaged and not easy to maintain and replace. Moreover, when the existing piezoelectric ceramic pickup sensor that is easy to install uses a bolt fixing method, due to the different installation positions of the piezoelectric ceramic pickup sensor, the structure cannot maintain the stability of the piezoelectric ceramic pickup sensor, which can cause the piezoelectric ceramic pickup sensor to shift during installation, affecting the normal use of the piezoelectric ceramic pickup sensor.
