摘要：
A wood boring insect detector (110) comprises a housing (120) defining a hollow interior chamber (126) and including an opening (127) connecting the interior chamber to the exterior； a spacer member (128) surrounding the opening and defining an internal cavity (129)； and an acoustic sensor (140) mounted within the interior chamber (126). A probe (130) projects through the opening and the internal cavity of the spacer. An exposed tip portion (132) of the probe is for insertion into a specimen (100). A base portion (134) of the probe is connected to the acoustic sensor (140). The spacer member defines a separation between the housing (120) and the specimen (100) and a depth of insertion of the probe tip (132) into the specimen. When the tip portion (132) is inserted into a specimen, wood boring insect activity within the specimen is transmitted as vibrations along the probe (130) to the acoustic sensor (140), which converts those vibrations to an output signal of a characteristic acoustic frequency indicative of the presence of wood boring insect activity within the specimen (100). The detector can include specially configured internal cavities/chambers (126, 129, 154), a mount (150) and a resilient pad (160), and a resilient outer sheath (170), which are physical elements that filter out much of the background noise for particularly good acoustic properties.L'invention concerne un détecteur d'insectes perceurs du bois (110), qui comprend un boîtier (120) définissant une chambre intérieure creuse (126) et comprenant une ouverture (127) reliant la chambre intérieure à l'extérieur ； un élément d'espacement (128) encerclant l'ouverture et définissant une cavité interne (129) ； et un capteur acoustique (140) monté à l'intérieur de la chambre intérieure (126). Une sonde (130) fait saillie à travers l'ouverture et la cavité interne de l'élément d'espacement. Une partie de pointe exposée (132) de la sonde est destinée à être insérée dans un échantillon (100). Une partie de b
