Sound output device
The present invention includes: a housing that includes an arrangement case in which an internal space is formed, and a sound guide tube in which a sound conduction space is formed; a feedback microphone to which an external sound is input; a first speaker unit that outputs a sound; and a second speaker unit that outputs a sound in an output band different from an output band of the sound output from the first speaker unit. The housing has inside a first space and a second space, the feedback microphone and the first speaker unit are arranged in the first space, the second speaker unit is arranged in the second space, and an equalizer that partitions the first space and the second space is disposed between the first speaker unit and the second speaker unit.
1. A sound output device, comprising:
a housing that includes an arrangement case in which an internal space is formed, and a sound guide tube in which a sound conduction space is formed;
a feedback microphone to which an external sound is input;
a first speaker unit configured to output a sound; and
a second speaker unit configured to output a sound in an output band different from an output band of the sound output from the first speaker unit,
wherein the housing has inside a first space and a second space,
the feedback microphone and the first speaker unit are arranged in the first space,
the second speaker unit is arranged in the second space, and
an equalizer that partitions the first space and the second space is disposed between the first speaker unit and the second speaker unit.
2. The sound output device according to claim 1 ,
wherein the second speaker unit is arranged in the sound conduction space.
3. The sound output device according to claim 1 ,
wherein the feedback microphone and the first speaker unit are held by the sound guide tube.
4. The sound output device according to claim 3 ,
wherein the sound guide tube is provided with a partition wall between the feedback microphone and the first speaker unit,
the partition wall is formed with a communication hole configured to allow communication between the feedback microphone and the first speaker unit, and
the communication hole penetrates in a direction perpendicular to an axial direction of the sound guide tube.
5. The sound output device according to claim 4 ,
wherein the first speaker unit and the second speaker unit are arranged apart from each other in the axial direction of the sound guide tube.
6. The sound output device according to claim 5 ,
wherein the first speaker unit and the feedback microphone are arranged apart from each other in the direction perpendicular to the axial direction of the sound guide tube.
7. The sound output device according to claim 1 ,
wherein a diaphragm of the first speaker unit and the equalizer are positioned to face each other.
