Dynamic Multi-function Speaker Unit
DMS Product Summary
■ DMS can realize all of the electrical signal composed of a sound source transform to vibration and
finely change the rhythmical sense per sound source to vibration and then realize the function of
bone transmission.
■ DMS includes vibration & speaker function and can control each function for its required usage.
■ DMS makes vertical vibration force with up and down movement, not the method that vibration
is created by rotating the eccentric poise as a vibration occurrence principle of existing motor.
Therefore, it can get stronger and stable vibration value than existing motor method.
DMS Product Function
■ Input Power : 2.0V(RMS) / Vibration Volume: 2G (at 260Hz) / Frequency Range : 200Hz ~ 400Hz
■ Vibration Function
ㅁ▶ Not rotation type vibration creation structure with the usage of DC electric current, the same
ㅁ▶ up & down vibration structure as general speaker unit with the usage of AC electric current,
ㅁ▶ it can control vibration part with step by step type.
ㅁ▶ Substitute the existing rotation type vibration motor and control the vibration volume with
ㅁ▶ free on a mobile phone.
ㅁ▶ With transformation all of the sound source to vibration, feel the sound as vibration and enjoy
ㅁ▶ the music. Thanks to the realization of sound and vibration at the same time, it can make
ㅁ▶ imaginary reality of game player & multimedia as like actuality.
■ Bone Conduction Function
ㅁ▶ With the function of the sense of touch sound through bone, it can reproduce touch sound
ㅁ▶ sound source(touch sound frequency) with the range of 300Hz ~ 800Hz. It can be applied to
ㅁ▶ the part of medical cure machinery with the usage of vibration sound.
ㅁ▶ In case of application to the mobile phone, even though the condition is too bad to have
ㅁ▶ conversation through phone, listen to conversation sound and communicate by phone is possible.
ㅁ▶ A person who has difficulty in hearing and the auditory handicapped by damage of the eardrum
ㅁ▶ and old generation also can hear sound through bone transmission.
■ Speaker & Receiver Function
ㅁ▶ DMS Unit, which includes the reproduction function of a micro speaker and voice range with
ㅁ▶ 300Hz ~ 3.4KHz under the audible range of a dynamic receiver is dual mode item and this is
ㅁ▶ integrated unit without fitting with vibration motor, speaker and receiver respectively.
ㅁ▶ DMS can be fitted at the existing point, where the speaker was fitted without the change of circuit.
