## Abstract

An electronic apparatus is disclosed. In one embodiment, an electronic apparatus comprises a panel, a piezoelectric vibrator, a first bonding member, and a second bonding member. The piezoelectric vibrator is located on an inner surface of the panel. The first bonding member is located between the panel and the piezoelectric vibrator to bond the piezoelectric vibrator to the panel. The second bonding member is located between the panel and the piezoelectric vibrator to bond the piezoelectric vibrator to the panel and has an elastic modulus lower than an elastic modulus of the first bonding member.

## Claims

### Claim 1

An electronic apparatus comprising:
a panel;
a piezoelectric vibrator located on an inner surface of the panel;
a first bonding member that is located between the panel and the piezoelectric vibrator to bond the piezoelectric vibrator to the panel; and
a second bonding member that is located between the panel and the piezoelectric vibrator to bond the piezoelectric vibrator to the panel and has an elastic modulus lower than an elastic modulus of the first bonding member.

### Claim 2 (depends on 1)

The electronic apparatus according to claim 1,
wherein the piezoelectric vibrator vibrates while being bent along a predetermined direction.

### Claim 3 (depends on 2)

The electronic apparatus according to claim 2,
wherein the second bonding member is located between the panel and an end in the predetermined direction of the piezoelectric vibrator.

### Claim 4 (depends on 3)

The electronic apparatus according to claim 3,
wherein the second bonding member is located between the panel and both ends in the predetermined direction of the piezoelectric vibrator.

### Claim 5 (depends on 2)

The electronic apparatus according to claim 2,
wherein the first bonding member is located between the panel and a central portion in the predetermined direction of the piezoelectric vibrator.

### Claim 6 (depends on 5)

The electronic apparatus according to claim 5,
wherein a bonding member composed of the first and second bonding members lies on the entirety of a surface of the piezoelectric vibrator on the panel side.

### Claim 7 (depends on 6)

The electronic apparatus according to claim 6,
wherein
the second bonding member includes:
a first portion extending in the predetermined direction from one end in the predetermined direction of the piezoelectric vibrator to a position that is at a distance of one third of a length in the predetermined direction of the piezoelectric vibrator from the one end; and
a second portion extending in the predetermined direction from another end in the predetermined direction of the piezoelectric vibrator to a position that is at a distance of one third of the length from the another end, and
the first bonding member lies between the first portion and the second portion.

### Claim 8 (depends on 1)

The electronic apparatus according to claim 1,
wherein the panel is made of sapphire.
