A headphone includes a speaker casing and a headband. The speaker casing has a main speaker unit and a support member that supports the main speaker unit. The speaker casing is connected to the headband, and the headband is to be placed on a head of a user. The support member supports the main speaker unit with a main plane of the main speaker unit being positioned at an angle ranging from 10° to 30° inclusive with respect to a main plane of the support member, so that the main plane of the main speaker unit faces a side of an ear lobe of the user.
1. A headphone comprising:
a speaker casing including a main speaker unit, a sub-speaker unit and a support member that supports the main speaker unit and the sub-speaker unit; and
a headband that is connected to the speaker casing and is to be placed on a head of a user, wherein:
the support member supports the main speaker unit with a main plane of the main speaker unit being positioned at an angle ranging from 10° to 30° inclusive with respect to a main plane of the support member, so that the main plane of the main speaker unit faces an ear lobe of the user, and
the support member support the sub-speaker unit with a main plane of the sub-speaker unit being positioned at an angle ranging from 30° to 50° inclusive with respect to the main plane of the support member, so that the main plane of the sub-speaker unit faces an ear lobe of the user.
2. The headphone according to claim 1 , wherein
the main speaker unit has a diaphragm, and
the support member supports the main speaker unit with a main axis of the diaphragm being positioned at an angle ranging from 60° to 80° inclusive with respect to the main plane of the support member.
3. The headphone according to claim 1 , wherein
the support member is a baffle plate on which the main speaker unit is mounted.
4. The headphone according to claim 1 ,
wherein the support member supports both the main speaker unit and the sub-speaker unit in an inclined position respectively so that the main axis of the main speaker unit intersects a main axis of the sub-speaker unit at a predetermined reference point.
5. The headphone according to claim 4 , wherein
a point estimated to be a location of a tympanic membrane of the user is set as the reference point.
6. The headphone according to claim 4 , wherein
the support member supports the sub-speaker unit so as to be positioned on a front side of the head of the user with respect to a central line of a baffle plate on which the main speaker unit is mounted or with respect to a central line of a protector that covers an opening of the baffle plate, and
the central line of the baffle plate or the central line of the protector is parallel to a longitudinal direction of a pinna of the user.
7. A headphone comprising:
a speaker casing including a main speaker unit, a sub-speaker unit and a support member that supports the main speaker unit and the sub-speaker unit; and
a headband that is connected to the speaker casing and is to be placed on a head of a user,
wherein two points estimated to be locations of two tympanic membranes of the user are set as two reference points, and an axis connecting the two reference points is set as a first axis,
wherein an axis that passes through the reference point, is perpendicular to the first axis, and is parallel to a front-back direction of the head of the user is set as a second axis,
wherein the support member supports the main speaker unit so as to be rotated around the second axis in a direction from the first axis to a top of the head of the user, so that a main axis of the main speaker unit passes through the reference point and is inclined at an angle ranging from 10° to 30° inclusive with respect to the first axis, and
wherein the support member support the sub-speaker unit such that a main axis of the sub-speaker unit passes through the reference point and is inclined at an angle ranging from 30° to 50° inclusive with respect to the first axis.
