a pair of housing blocks, wherein each housing block of the pair of housing blocks is coupled to the second end portion of a corresponding slider block of the pair of slider blocks via coupling portions, and wherein each housing block of the pair of housing blocks includes a headphone unit;
an operation section configured to receive a switching instruction from a user; and
a control unit configured to selectively drive the headphone unit included in the pair of housing blocks and the speaker unit included in the pair of slider blocks, based on the received switching instruction.
2. The headphone type acoustic apparatus according to claim 1 , further comprising:
a first amplifier configured to amplify a first audio signal supplied to the headphone unit; and
a second amplifier configured to amplify a second audio signal supplied to the speaker unit,
wherein the control unit is further configured to switch between the first amplifier and the second amplifier based on the received switching instruction.
3. The headphone type acoustic apparatus according to claim 1 , wherein
the speaker unit includes:
a speaker driver unit including:
a diaphragm configured to vibrate in a thickness direction of the corresponding slider block of the pair of slider blocks;
a magnetic circuit configured to drive the diaphragm; and
a case configured to house the diaphragm and the magnetic circuit, wherein a portion of the diaphragm is exposed from a first surface of the case; and
a lid, wherein a space is present between the lid and the first surface of the case, and wherein the lid includes an opening to spill sound from a first end of the space in a direction orthogonal to a slide direction of the corresponding slider block.
4. The headphone type acoustic apparatus according to claim 3 , wherein
the first end of the space in the direction orthogonal to the slide direction of the corresponding slider block is on a front side in a state in which the headphone type acoustic apparatus is worn by the user.
5. The headphone type acoustic apparatus according to claim 3 , wherein each slider block further includes:
a cushion member, wherein the cushion member is attached to the case included of the speaker unit.
