Liquid discharge head and liquid discharge apparatus

A liquid discharge head comprising:

• a nozzle plate having multiple nozzles from which a liquid is discharged in a liquid discharge direction;
• a channel substrate having multiple individual liquid chambers communicating with the multiple nozzles, respectively;
• a frame having:
• a first end adjacent to the channel substrate;
• a second end opposite the first end in the liquid discharge direction;
• and
• a common liquid chamber between the first end and the second end and communicating with the multiple individual liquid chambers;
• a vibration attenuator between the first end and the second end in the common liquid chamber, the vibration attenuator having a through hole through which the liquid flows in the common liquid chamber;
• wherein the vibration attenuator includes multiple dampers each including:
• a first thickness portion;
• a second thickness portion facing the first thickness portion, the second thickness portion thicker than the first thickness portion;
• and
• a damper partition between the first thickness portion and the second thickness portion and defining an air layer enclosed by the first thickness portion, the second thickness portion, and the damper partition,
• the first thickness portion is deformable into the air layer toward the second thickness portion;
• wherein each of the frame and the channel substrate has a joint face at which the frame and the channel substrate are joined with each other,
• the first thickness portion has a face parallel to the joint face, and
• the first thickness portion faces the multiple individual liquid chambers and is closer to the multiple individual liquid chambers than the second thickness portion.
