Abstract

An earphone and a manufacturing method of the earphone are disclosed. The earphone includes a diaphragm configured to vertically move in response to a vibration occurring based on a movement of an armature and delivered through a rod.

Claims

1. An earphone comprising:

an armature configured to vertically move between permanent magnets based on a magnetic polarity of a coil; and

a diaphragm configured to vertically move in response to a vibration occurring based on a movement of the armature,

wherein the diaphragm is integrally formed with a rod configured to deliver the vibration occurring based on the movement of the armature.

2. The earphone of claim 1, wherein the rod is disposed perpendicular to a partial area of the diaphragm.

3. The earphone of claim 1, wherein one end of the rod is connected to one end of the armature.

4. The earphone of claim 1, wherein at least one hole or at least one protrusion having a predetermined length is provided at one end of the rod.

18. The earphone of claim 1, wherein the armature is divided into an upper portion and a lower portion having a symmetric relationship or an asymmetric relationship, or the armature is not divided into the upper portion and the lower portion.

19. The earphone of claim 18, wherein when the armature is divided into the upper portion and the lower portion, the armature is provided in a U shape or a 90-degree rotated U shape.

5. An earphone comprising:

an armature configured to vertically move between permanent magnets based on a magnetic polarity of a coil; and

a diaphragm configured to vertically move in response to a vibration occurring based on a movement of the armature,

wherein the diaphragm is integrally formed with a fixture configured to fix the diaphragm or a rod configured to deliver the vibration occurring based on the movement of the armature.

6. The earphone of claim 5, wherein an area in which the diaphragm and the fixture are connected to each other is present, and a connector for a modulus of elasticity of the diaphragm is disposed in the area.

7. The earphone of claim 6, wherein a length of the connector, a thickness of the connector, or a number of connectors is determined based on the modulus of elasticity of the diaphragm.

8. The earphone of claim 5, wherein an area in which the diaphragm and the fixture are connected to each other is present, and a hole for a modulus of elasticity of the diaphragm is formed in the area.

9. The earphone of claim 8, wherein a size of the hole or a number of holes is determined based on the modulus of elasticity of the diaphragm.

10. The earphone of claim 5, wherein the rod is disposed perpendicular to a partial area of the diaphragm.

11. The earphone of claim 5, wherein one end of the rod is connected to one end of the armature.

12. The earphone of claim 5, wherein at least one hole or at least one protrusion having a predetermined length is provided at one end of the rod.

13. An earphone comprising:

an armature configured to vertically move between permanent magnets based on a magnetic polarity of a coil; and

a diaphragm configured to vertically move in response to a vibration occurring based on a movement of the armature,

wherein the diaphragm is integrally formed with a guide used in housing of the earphone or a rod configured to deliver the vibration occurring based on the movement of the armature.

14. The earphone of claim 13, wherein the guide comprises an area forming a double step difference with an upper face of the guide so as to arrange the diaphragm below the upper face by a predetermined depth.

15. The earphone of claim 13, wherein the rod is disposed perpendicular to a partial area of the diaphragm.

16. The earphone of claim 13, wherein one end of the rod is connected to one end of the armature.

17. The earphone of claim 13, wherein at least one hole or at least one protrusion having a predetermined length is formed at one end of the rod.

20. An earphone manufacturing method comprising:

arranging an armature;

arranging a diaphragm integrally formed with a rod directly connected to the armature at an upper end of the armature;

arranging a coil covering the armature; and

arranging a permanent magnet in an area different from an area in which the coil is arranged.

21. The earphone manufacturing method of claim 20, further comprising:

arranging a guide used in housing of the earphone,

wherein the guide is integrally formed with the diaphragm, or connected to the diaphragm through a fixture or a connector of the diaphragm.
