    摘要: Disclosed is an open ear headphone, including a housing, a speaker arranged in an accommodating space inside the housing to define the accommodating space into a front cavity and a rear cavity, a connecting member including opposite first and second ends, and a supporting member connected to the second end and including a supporting portion and a sound outlet channel. A sound outlet is provided on a surface of the housing and is in acoustic communication with the front cavity. The first end is connected to the surface of the housing. When a user wears the open ear headphone, the housing is located in a concha cavity of the user's ear, the supporting portion at least leans against a lower edge of the concha cavity, and the sound outlet channel is in acoustic communication with the user's ear canal and is not in contact with the user's ear.

    摘要: This application provides a combination phase plug, and a compression driver and a speaker using same. The combination phase plug of this application includes a first phase plug and a second phase plug. The second phase plug is located under the first phase plug. The first phase plug includes a cone, a plurality of first fins, and a plurality of second fins. The first fins and the second fins are located on an outer surface of the cone in a staggered manner. A first gap exists between any first fin and a second fin adjacent to the first fin. The second phase plug includes a round-disc base, a combining portion, and a plurality of second gaps. The combining portion is located in the center of the round-disc base and the combining portion and the cone can be combined with each other. The second gaps are located between an outer edge of the round-disc base and the combining portion. The first gaps are respectively aligned with the second gaps to form a plurality of channels to improve the acoustic performance.

    摘要: A good output state of sound is ensured without a cost increase. A speaker unit includes: a vibration plate; a magnetic circuit; a bobbin to which an inner peripheral portion of the vibration plate is attached and which is varied in an axial direction by the magnetic circuit; and a cap attached to the vibration plate and located to face the bobbin in the axial direction of the bobbin, in which a center axis of the bobbin is arranged in a state of being inclined with respect to a horizontal plane or a vertical plane, and the cap is formed in a shape eccentric to the center axis of the bobbin. Thus, since the cap is eccentric to the center axis in a state in which the center axis of the bobbin is inclined with respect to the horizontal plane or the vertical plane, it is possible to freely control a pointing direction in an inclined direction, good directivity characteristics can be obtained, and a good output state of sound can be ensured without a cost increase.
