Abstract

An electronic keyboard instrument includes a housing, a keyboard provided in connection with the housing and aligned in a left-right direction of the housing, a sound-emitting component provided inside the housing, and a reflector comprising a reflection surface configured to reflect sound from the sound-emitting component and provided at an upper portion of the housing inside the housing.

First claim

What is claimed is:

1 . An electronic keyboard instrument comprising:
a housing; a keyboard provided in connection with the housing and aligned in a left-right direction of the housing; a sound-emitting component provided inside the housing; and a reflector provided at an upper portion of the housing inside the housing and comprising a reflection surface configured to reflect sound from the sound-emitting component.

2 . The electronic keyboard instrument according to claim 1 , further comprising:
an upper surface component provided at an upper portion of the housing, wherein the reflector is fixed to a lower portion of the upper surface component inside the housing.

3 . The electronic keyboard instrument according to claim 2 ,
wherein the reflector is attached to the upper surface component via an attachment.

4 . The electronic keyboard instrument according to claim 2 ,
wherein the upper surface component comprises a hole that opens upwards from an inside of the housing.

5 . The electronic keyboard instrument according to claim 4 ,
wherein the reflector is provided such that the reflection surface is inclined to face an upper side of the housing.

6 . The electronic keyboard instrument according to claim 5 ,
wherein the reflector is provided such that the reflection surface is inclined at an angle within a range of 60 degrees to 70 degrees relative to a front-back direction of the housing, towards an upper side of the housing.

7 . The electronic keyboard instrument according to claim 1 ,
wherein the sound-emitting component comprises a low-pitched sound-emitting component provided at a first end portion in the left-right direction and configured to emit sound in a low-pitched sound range and a high-pitched sound-emitting component provided at a second end portion in the left-right direction and configured to emit sound in a high-pitched sound range.

8 . The electronic keyboard instrument according to claim 7 ,
wherein the reflector comprises a first reflector provided above the low-pitched sound-emitting component and a second reflector provided above the high-pitched sound-emitting component.

9 . The electronic keyboard instrument according to claim 8 ,
wherein the first reflector and the second reflector are respectively provided such that their reflective surfaces are inclined towards the high-pitched sound-emitting component from the low-pitched sound-emitting component in the left-right direction.

10 . The electronic keyboard instrument according to claim 9 ,
wherein the first reflector and the second reflector are respectively provided such that their reflective surfaces are inclined at an angle within a range of 5° to 10° relative to the left-right direction of the housing, towards the high-pitched sound emitting component from the low-pitched sound emitting component in the left-right direction.

11 . The electronic keyboard instrument according to claim 7 ,
wherein the low-pitched sound-emitting component is provided at a left end portion in the left-right direction inside the housing, and wherein the high-pitched sound-emitting component is provided at a right end portion in the left-right direction inside the housing.

12 . The electronic keyboard instrument according to claim 8 ,
wherein the first reflector and the second reflector are provided with a same inclination angle relative to the housing.

13 . The electronic keyboard instrument according to claim 1 , further comprising:
a perforated component comprising a hole that opens from an inside of the housing towards a front side and provided further forwards of the housing than the reflector and further upwards than the keyboard.
