ㆍWith the vibration, speaker & receiver function integrated into one frame, miniaturization of mobile phone & game player. 
    
ㆍNo motor rotation RPM noise under Vibration mode (etiquette function) and realize smooth vibration.  
    
ㆍIn case of phone conversation under noisy working site, sound receipt & sending can be through bone transmission.  
    
ㆍListen to three-dimensional sensory sound thanks to the realization of the vibration tempo the same as sound source as reproduce on the condition that melody sound in mobile phone & vibration function (vibration sound source bell unction). (It is impossible for general vibration motor, of which vibration is originated from rotation to realize vibration tempo the same as sound source)  
 

Vibration Fuction

ㆍNot rotation type vibration creation structure with the usage of DC electric current, the same up and down vibration structure as general speaker Unit with the usage of AC electric current, it can control vibration part with Step-By-Step type.  
    
ㆍSubstitution the existing rotation type vibration motor and control the vibration  volume with free in mobile phone.  
    
ㆍWith transformation all of the sound source to vibration, feel the sound as vibration and enjoy the music and thanks to the realization of sound and vibration at the same time, it can make imaginary reality of game player & multimedia as like actuality.  
    
ㆍLow electricity consumption noise compared with the existing rotation type vibration motor.  
    

Vibration Feature

ㆍ Input Power: 2.0V (RMS)  
    
ㆍ Vibration volume: 2G (at 260Hz) 
    
ㆍ Max vibration frequency range: 200Hz ~ 400Hz.  

Bone Transmission Function

    
ㆍWith the function of the sense of touch sound through bone, it can reproduce touch sound source(touch sound frequency)with the range of 300Hz~800Hz. It can apply to the part of medical cure machinery with the usage of vibration sound. 
    
ㆍIn case of application to mobile phone, even though the condition is too bad to have conversation through phone, listen to conversation sound and communicate by phone. (bone transmission mode in mobile phone)  
    
ㆍA person who has diffculty in hearing and the auditory handicapped by damage of the eardrum and old generation also can hear sound through bone transmission. 
    
ㆍA person who has too senstive the eardrum among the ordinary people or works through phone for many hours use it as the protection function of the eardrum.   
    

Speaker&Receiver Function   
 

ㆍDMS Unit, which includes the reproduction function of Dynamic Micro speaker and  voice range with 300Hz~3.4KHz under the audible range of receiver, is dual mode item and this is the integrated unit without fitting with vibration motor & speaker, receiver respectively.  
    
ㆍDMS can be fitted the existing point, where the speaker was fitted without the change of circuit.  
    ex1) Item fitted with general speaker → speaker and vibration function.  
    ex2) Item fitted with Dual Mode speaker → speaker & receiver, vibration function.   

ㆍCost down effect as a result of integrated complex type.  
    
ㆍAccording to DMS application, miniaturization and light weight for set development.  
    
ㆍIncrease of supplementary marketing factor. 
   ① Item development with the usage of sensory sound.

   ② Bone transmission function for handicapped person and new item development for the increase of old age generation.

   ③ Contribution to the development of medical & military equipment.

   ④ Increase of sale & creation of value added with differentiated item development

   ⑤ Advertisement effect with additional function.
