Embodiment Construction

[0018] Referring to the figure, the housing 1 in the figure; polyurethane glue 2; metal substrate 3; piezoelectric sensitive element 4, acoustic load conductor material 5; solder joint 6; sealing ring 7, sealing perforation screw 8; watertight cable 9; cable The core wire 10 is one pole; the other pole 11.

[0019] The piezoelectric sensitive element 4 adopts PZT (piezoelectric ceramics), which is a disc with a diameter of 50mm-100mm and a thickness of 0.5mm-1.0mm. It has piezoelectric characteristics, that is, when it is subjected to an external force, it generates charges; It deforms. Therefore, input the alternating music electric signal, it just sends out the vibrating sound of music. According to the characteristics of the palace tone music of the present invention, most of them are low frequencies of several hundred Hz, and the volume of the bath is limited simultaneously, requiring a small-volume music transmitting transducer. This is a contradiction for the transmitt...

Abstract

The invented piezoelectric transducer includes the following components: shell body, piezoelectric sensing elements, metal substrate, sealing ring, screw with central hole, electric cable, sound-loading conductor material and signal wire. Said invention also provides the concrete structure of the above-mentioned every component, and provides the connection mode of all the components. The invented transducer alopts ''indirect supporting'' fixing mode and adopts double-face radiation, so that as compared with existent technology its resonance frequency and impedance are lower.

Description

technical field [0001] The invention relates to a transducer, in particular to a piezoelectric transducer for underwater music somatosensory vibration emission. Background technique [0002] Since ancient times, humans have recognized the influence of music on emotions and physiology, and used music to relieve the pain of diseases. In recent years, with the increasing number of sub-healthy people and the rise of natural therapy in developed countries, music therapy has gradually gained people's attention and popularity. The basis of music therapy is the human body's music perception. The human body's music perception and acceptance pathway is the ear (hearing). In the past, music therapy in China was mainly based on listening. In 2002, the Institute of Clinical Medicine of the China-Japan Friendship Hospital of the Ministry of Health introduced the somatosensory music vibration mattress and sofa invented by Mr. Akira Komatsu, director of the All Japan Music Therapy Allianc...
