Abstract

An earpiece for communications comprises a frame, a vibration system disposed in the frame and a magnetic field system disposed in the frame. The vibration system includes a vibrating armature, a diaphragm and a connecting rod. The magnetic field system includes a magnet to generate a first magnetic field on a first axis and a coil to generate a second magnetic field on a second axis. One of the magnet and the coil is connected to the frame. The first and the second magnetic fields produce a net magnetic force to cause the vibration system to move. The first axis is parallel to the second axis.

Claims

1. An earpiece for communications, comprising:

a frame;

a vibration system disposed in the frame, the vibration system including a vibrating armature, a diaphragm and a connecting rod, wherein the vibrating armature comprises a stationary portion and an extending portion, the stationary portion being connected to the frame, one end of the extending portion being connected to the stationary portion to form an arc portion and the other end of the extending portion being capable of moving about the arc portion; and

a magnetic field system disposed in the frame, the magnetic field system including a magnet to generate a first magnetic field on a first axis and a coil to generate a second magnetic field on a second axis, one of the magnet and the coil being connected to the frame, the first and the second magnetic fields producing a net magnetic force to cause the vibration system to move, wherein the first axis is parallel to the second axis, wherein one of the coil and the magnet is connected to the frame through the stationary portion, the other one of the coil and the magnet is connected to the extending portion.

2. The earpiece of claim 1, wherein the magnet and the coil are disposed in series with the diaphragm.

3. The earpiece of claim 1, wherein the extending portion includes a plurality of arms, a first of the plurality of arms serving as a coil pole, the coil pole being at least partially surrounded by the coil.

4. The earpiece according to claim 3, wherein a second arm of the plurality of arms is connected to the stationary portion to form the arc portion and a third arm of the plurality of arms is connected to the connecting rod.

5. The earpiece of claim 3, wherein the extending portion is substantially a “

U”

shape.

6. The earpiece of claim 3, wherein the magnet is connected to the extending portion and the coil is connected to the frame via the stationary portion.

7. The earpiece according to claim 3, wherein the coil is connected to the extending portion and the coil is connected to the frame via the stationary portion.

8. An earpiece for mobile communications, comprising:

a frame;

a vibration system including a vibrating armature, a diaphragm and a connecting rod, the vibrating armature having a stationary portion and an extending portion, the stationary portion being connected to the frame, one end of the extending portion being connected to the stationary portion to form an arc portion and the other end of the extending portion being capable of movement; and

a magnetic field system including a magnet to generate a first magnetic field on a first axis and a coil to generate a second magnetic field on a second axis, one of the magnet and the coil is connected to the frame through the stationary portion, the first and the second magnetic fields producing a net magnetic force to cause the extending portion to vibrate, the extending portion transmitting vibration to the diaphragm through the connecting rod, wherein the first axis is parallel to the second axis, wherein the other one of the coil and the magnet is connected to the extending portion.

9. The earpiece of claim 8, wherein the net magnetic force is perpendicular to the first axis.

10. The earpiece of claim 8, wherein the extending portion includes a plurality of arms, a first arm of the plurality of arms serving as a coil pole, the coil pole being at least partially surrounded by the coil.
