Abstract

To provide an earphone with improved sound quality.SOLUTION: An earphone 10 generates bone-conducted sound in which mechanical vibrations generated in a core module 11 are transmitted mainly through a medium such as the user's skull, and air-conducted sound in which mechanical vibrations generated in the core module 11 are transmitted mainly through a medium such as air. When the user's ear canal is open without being blocked or obstructed by the earphone 10 in the worn state, the sound generated by the earphone 10 is mainly the bone-conducted sound, and the air-conducted sound enhances the bone-conducted sound, thereby improving the sound quality of the earphone 10.SELECTED DRAWING: Figure 12

Claims

1. The system includes a support assembly and a core module connected to the support assembly, wherein the support assembly supports the core module so that it is mounted in a mounting position, and the core module includes a core housing, an energy converter, and a vibration panel, wherein the energy converter is installed in a housing cavity of the core housing, and the vibration panel is connected to the energy converter and transmits the mechanical vibrations generated by the energy converter to the user. When worn, as viewed from the direction in which the coronal axis of the human body is located, the center of the vibration panel on the side facing the wearing position is closer to the external auditory canal of the user's ear than the center of the core housing on the side facing the wearing position, in the direction in which the sagittal axis of the human body is located. An earphone characterized in that the center of the energy conversion device, when orthographically projected onto the core housing along the vibration direction of the energy conversion device, coincides with the center of the core housing on the side facing the energy conversion device in the vibration direction, and the center of the vibration panel, when orthographically projected onto the core housing along the vibration direction, does not coincide with the center of the energy conversion device, when orthographically projected onto the core housing along the vibration direction.

2. The earphone according to claim 1, further comprising an adapter housing connecting the core housing and the support assembly, wherein the adapter housing includes a cylindrical side wall located on the outer circumference of the core housing, and the orthographic projections of the core housing and the cylindrical side wall onto a reference plane perpendicular to the vibration direction of the energy conversion device have a first center and a second center, respectively, and in the worn state, the first center is closer to the external auditory canal of the user's ear than the second center.

3. The earphone according to claim 2, characterized in that the core housing rotates about a first axis relative to the adapter housing, and the first center and the second center are spaced apart along the direction in which the first axis is located.

4. The earphone according to claim 3, characterized in that the first center and the second center are located on the first axis.

5. The earphone according to claim 3, characterized in that the adapter housing rotates about a second axis relative to the support assembly, and the second axis intersects the first axis.

6. The earphone according to any one of claims 2 to 5, further comprising a battery and a motherboard coupled to the energy conversion device, the adapter housing further comprising an intermediate plate connected to the inside of the cylindrical side wall and a case engaged with the cylindrical side wall, the battery or the motherboard being installed between the case and the intermediate plate, and the core housing being located on the side of the intermediate plate away from the case.

7. The earphone according to any one of claims 2 to 5, characterized in that the support assembly is installed as a head beam assembly, the head beam assembly bypasses the top of the user's head and brings the vibrating panel into contact with the user's cheek, and in the worn state, the head beam assembly forms a first contact point with the top of the user's head, the vibrating panel forms a second contact point with the user's cheek, and the distance between the second contact point and the first contact point in the direction of the sagittal axis of the human body is 20 mm to 30 mm.

8. The earphone according to claim 7, wherein the head beam assembly includes an arc-shaped head beam member and an adapter member, the arc-shaped head beam member bypasses the top of the user's head, the adapter member includes a first connecting portion, an intermediate transition portion and a second connecting portion, the intermediate transition portion connects the first connecting portion and the second connecting portion, the first connecting portion and the second connecting portion are each bent relative to the intermediate transition portion and extended in opposite directions, the first connecting portion is connected to the arc-shaped head beam member, the second connecting portion is connected to the adapter housing, and the intermediate transition portion is inclined with respect to the vertical axis of the human body when viewed from the direction in which the coronal axis of the human body is located.

9. The earphone according to claim 8, characterized in that the bending angle of the first connection portion with respect to the intermediate transition portion is 90° or more and less than 180°.

10. The earphone according to claim 8, characterized in that the bending angle of the second connection portion with respect to the intermediate transition portion is 90° or more and less than 180°.

11. The earphone according to claim 8, characterized in that, when worn, the first connecting portion is parallel to the second connecting portion when viewed from the direction in which the coronal axis of the human body is located, and the distance between the first connecting portion and the second connecting portion is 20 mm to 30 mm.

12. The earphone according to claim 8, characterized in that the adapter housing is provided with a rotating shaft cavity, and the adapter member is inserted into the rotating shaft cavity along the axial direction of the rotating shaft cavity.

13. The earphone according to claim 12, characterized in that a position limiting groove is formed on the outer peripheral wall of the adapter member, a position limiting block is provided on the inner peripheral wall of the rotating shaft cavity, and the position limiting block is fitted into the position limiting groove so as to limit the rotation angle of the adapter member with respect to the rotating shaft cavity.
