Embodiment 1

[0038] according to figure 1 Shown to make an external magnetic type electric underwater music somatosensory vibration launch transducer, including a cylindrical shell 13 made of aluminum, the side wall of the shell 13 has a cable sealing port 5, and the inner wall of one end has a mounting In the groove of the vibrating plate 7, a groove is opened on the inner bottom surface of the housing 13, and a magnetic field generating device is arranged in the groove. The magnetic field generating device includes a ring-shaped NdFeB permanent magnet with a central magnetic guide column 12 The lower magnetically conductive plate 14 and the upper magnetically conductive plate 8. A NdFeB annular permanent magnet 9 is inserted into the center of the magnetic guide column 12. The inner diameter of the NdFeB annular permanent magnet 9 is 25 mm, and the outer diameter is 40 mm. There is a gap of 1mm-2mm, and the NdFeB annular permanent magnet 9 is polarized on the upper and lower planes, wit...

Embodiment 2

[0047] according to figure 2 Make an internal magnetic type electric underwater music somatosensory vibration transmitting transducer, the structure of this transducer is only the magnetic field generating device is different from embodiment 1, and the rest is the same as embodiment 1, and will not be described in detail here.

[0048] The internal magnetic field generating device used in this embodiment: consists of NdFeB permanent magnet 9, magnetic short-circuit cover 15, magnetic conducting ring 16, and lower magnetic conducting plate 14; one of them is a "concave" shaped lower magnetic conducting plate 14 , a disc-shaped NdFeB permanent magnet 9 is arranged in the groove of the lower magnetic guide plate 14, the diameter of the NdFeB permanent magnet 9 is 38mm-50mm, and the thickness is 6mm-20mm. The upper part is the N pole and the lower part is the S pole; The iron-boron permanent magnet 9 is bonded with non-magnetic materials such as copper and aluminum as the magneti...

Embodiment 3

[0055] according to image 3 Make the radial magnetization electric underwater music somatosensory vibration transmitting transducer, the structure of this transducer is only the magnetic field generating device is different from the embodiment 1, and the rest is the same as the embodiment 1, and will not be described in detail here.

[0056] The radial magnetic field generating device includes: a skeleton 17 made of non-magnetic materials such as copper, aluminum, and non-metal with a cross-section of "III" type, the outer circle of the center column of the "III" type skeleton 17 There is a concave ring on the circumference, and there is also a groove on the inside garden circumference of the protruding part of the outer ring of the skeleton 17. The NdFeB permanent magnet 9 is composed of two concentric rings, one is the NdFeB permanent magnet outer ring 9, and the other is the NdFeB permanent magnet outer ring 9. NdFeB permanent magnet inner ring 9', two concentric rings are...

Abstract

The transducer includes following parts and structure: (1) there is opening for sealing cable on sidewall of the cylindrical shell, and there is flute on inner wall of the shell for placing vibrant plate; magnetic field generator is setup inner bottom surface of the shell; (2) voice coil cover is installed on a matched hole located on middle of the vibrant plate; vibrant plate, voice coil cover and voice coil are pasted together through fire resistant glue; voice coil inside the voice coil cover is extended to magnetic field generator; (3) perforation bolt can be fixed on screw thread of opening for sealing cable; rubber washer is inside the opening so as to seal the exit of cable; (4) the cable is connected to the voice coil; through screw, clasp is fixed on the shell; and through clasp, vibrant plate is fixed on the shell; polyurethane is filled between the vibrant plate and clasp; thus, the vibrant plate and clasp is solidified and sealed.

Description

technical field [0001] The invention relates to a transducer, in particular to an electric underwater music somatosensory vibration transmitting transducer. 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 Alliance, t...
