Problems solved by technology

Such a structure makes the manufacturing process unreasonable, and becomes a factor that reduces productivity. Installing two magnets not only leads to an increase in production cost, but also places the magnets at positions facing each other during assembly.
If the direction of the magnet is not aligned correctly, its characteristics will be affected, so that high productivity cannot be ensured, which are some inherent problems of previous inventions

Embodiment Construction

[0018] Fig. 1 is an exploded oblique view of an embodiment of a bone conduction speaker according to the present invention, and Fig. 2 is a longitudinal sectional view of the embodiment of the above bone conduction speaker.

[0019] On the vibration resonator 20 that is arranged in the sleeve (not shown in the figure), make extensions 30, 30 ' to four directions, and install voice coil 40 and central magnetic pole 50 thereon, and use screw on its top 80 fixes the vibrating plate 70 to which the iron piece 60 is attached.

[0020] At the upper center of the iron piece 60, a permanent magnet 90 is attached.

[0021] A more detailed description is as follows: the vibration resonator 20 is made in such a way that the central magnetic pole 50 is vertically arranged in the center of the plate-shaped part on which the voice coil 40 is placed, and then radially extended in four directions on the periphery of the plate-shaped part. Portions 30, 30'. The two opposite extensions 30 hav...

Abstract

The provide manufacturing technology and method for a bone conductive speaker that enables a person to be aware and recognize audio signal, with the cranial bones of a human body, through the vibrations of a vibrator. In a bone conductive speaker, a magnet is not installed proximately to a voice coil in a configuration box, but one magnet is installed in an upper portion of an iron piece. Thus, the trouble of matching magnet directionality is eliminated, not only characteristics adjustment can be made wider by enlarging the size of the voice coil, but also strength adjustment that depends on the changes in the size of the magnet can be significantly facilitated, and the bone conductive speaker can be made small-sized and lightweight.

Description

technical field [0001] The present invention relates to bone conduction loudspeaker technology and manufacturing method for consciously sensing the vibration of a vibrator and recognizing audio signals by human head bones. Background technique [0002] Hearing aids used by occupational and presbycusis patients, or bone conduction speakers such as headphones in radio communication equipment used in call centers who want to listen to the surrounding conversation and talk at the same time, do not vibrate the air with the help of a vibrating plate, The mechanism of generating sound waves and then conducting them is the bone conduction mechanism in which the vibrator turns the sound into vibrations and propagates through direct contact with objects, that is, the vibration is applied to the human skull, and such vibrations are sensed by the auditory nerve, that is, by means of The vibration of the bones transmits the sound waves to the auditory nerve of the human body, rather than...
