Description

Actuator with a combination of a speaker and a vibrator {Actuator with a combination of a speaker and a vibrator}

The present invention enables simultaneous implementation of sound and vibration in both directions, thereby implementing the function of a speaker that implements sound and the function of a vibrator in a complex manner, so that it can be applied not only to speakers but also to content and entertainment in a wide range of industries, such as movie theaters. It is a combination of speakers and vibrators that allows you to understand the situation through sound in chairs, gaming chairs, car seats, etc., as well as feel the current situation through the vibration of the body itself, so that the real situation can be realized as realistically as possible. It's about actuators.

A speaker is a device that reproduces electrical signals as sound. A conventional speaker consists of a trumpet-shaped frame, a cone-shaped diaphragm that vibrates inside the frame, an edge surround that supports the outer circumference of the diaphragm on the upper side of the frame, and A bobbin whose upper end is fixed to the center of the diaphragm on the lower side of the diaphragm, a damper whose outer circumference is fixed to the frame and whose inner circumference is fixed to the bobbin, a voice coil wound on the bobbin, and a donut shape arranged on the outside of the voice coil. There is a permanent magnet, a donut-shaped upper plate fixedly placed between the frame and the permanent magnet, a lower plate that covers the lower part of the permanent magnet, and a vibration space in which the bobbin vibrates up and down between the permanent magnet and the upper plate. , a pole piece protruding from the lower plate to the inside of the bobbin, and a dust cap to block the inside of the speaker from external dust and maintain the shape of the diaphragm.

Among the above configurations, the diaphragm, edge surround, bobbin, and damper belong to the vibration system, and the voice coil, permanent magnet, upper plate, lower plate, and pole piece belong to the magnetic circuit system. In these speakers, when an electrical signal is input from the amplifier to the voice coil, a current according to the electrical signal is formed in the voice coil, and mutual interference occurs between the current in the voice coil and the magnetic field formed by the permanent magnet, upper and lower plates, and pole piece. The voice coil receives a magnetic force corresponding to the electrical signal, the bobbin vibrates due to this magnetic force, and the diaphragm vibrates along with the vibration of the bobbin, generating sound.

The general speaker as described above simply has the function of allowing sound to be expressed in two directions or one direction,

Nearby, the title of the invention, Patent Registration No. 10-0542928, ‘Speaker for both vibration and sound’, is searched as prior art, and looking at the specific structure of this, it is as follows.
