That is, the holder member 41 is provided with a camera housing portion 42 and a vibrator housing portion 43, which are formed so as to surround the camera unit 17 and the vibrator 31, respectively.
The camera unit 17 is accommodated in the camera accommodating portion 42 so that the rotating body 22 can rotate with respect to the holder member 41.
Further, since the elastic member 35 is elastically deformed and sandwiched between the vibrator 31 and the vibrator housing portion 43 in a state of being housed in the vibrator housing portion 43, the vibrator 31 is fixed integrally with the holder member 41. become. In this accommodated state, the rotation axis A1 of the shaft body 32 of the vibrator 31 is substantially perpendicular to the arrangement direction of the camera unit 17 and the vibrator 31, and is in the longitudinal direction of the shaft 21 that serves as the rotation axis of the camera unit 17. It is almost orthogonal.
[0014]
The holder member 41 is formed with three through holes 44, 46, 47 penetrating in a direction orthogonal to the axis of the shaft 21 of the camera unit 17 and the rotation axis A 1 of the vibrator 31. A slit 45 is formed in a part of the circumferential direction of the peripheral edge forming 44.
As shown in FIG. 3, the through-hole 44 is a tapered protrusion formed in the case member 51 when the holder member 41 is placed inside the case member 51 constituting the second housing 3. 52 is inserted. For this reason, the diameter of the through hole 44 is increased when the protruding portion 52 is inserted, and the protruding portion 52 is lightly fitted into the through hole 44. The case member 51 is a member that forms the inner surface 14 side of the second housing 3, and is coupled to the case member (not shown) that forms the outer surface 15 side of the second housing 3 in the thickness direction. Thus, the second casing 3 is configured.
Therefore, after the holder member 41 is placed inside the case member 51 and before the holder member 41 is sandwiched and fixed by the two case members constituting the second housing 3, another speaker or the like is used. Even if an electronic component is mounted, the position of the holder member 41 can be prevented from shifting with respect to the case member 51.

Is transmitted from the proximal end portion 5 to the distal end portion 9 of the first housing 2.
In addition, since the notification content is displayed on the display unit 11 when the notification is made by the vibrator 31, the photographing by the camera unit 17 is interrupted. Therefore, even if the camera unit 17 vibrates with the holder member 41, there is no problem that the photographed image is blurred.
[0018]
As described above, according to the mobile phone 1, the vibration direction of the vibrator 31 is equal to the arrangement direction of the camera unit 17 and the vibrator 31 in the holder member 41, that is, the longitudinal direction of the holder member 41. The entire holder member 41 can be vibrated. And since the 2nd housing | casing 3 is vibrated via the holder member 41 which has a volume larger than the vibrator 31, the 2nd housing | casing 3 whole can be vibrated equally easily. Therefore, rattling of the second casing 3 on which the vibrator 31 is mounted can be suppressed.
Further, since the camera unit 17 and the vibrator 31 are integrally fixed to the holder member 41, the camera unit 17 and the vibrator 31 can be incorporated into the second housing 3 at the same time, and various electronic components The manufacturing efficiency of the mobile phone 1 can be improved by reducing the number of steps to be incorporated into the second housing 3.

Further, since the elastic member 35 can be elastically deformed, the gap between the vibrator 31 and the vibrator housing portion 43 can be filled, so that it is not necessary to set the size of the vibrator housing portion 43 with high accuracy, and the holder member 41. Can be easily manufactured.
Further, by arranging the holder member 41 on which the vibrator 31 is mounted on the base end portion 6 side of the second housing 3, when the vibrator 31 vibrates, the second housing is interposed via the holder member 41. At the same time as the body 3 vibrates, the first housing 2 vibrates via the hinge portion 4, so that the two housings 2 and 3 can be evenly vibrated.
[0020]
Further, the position of the holder member 41 with respect to the case member 51 can be correctly held by the through-hole 44 having the slit 45 formed in the holder member 41 and the tapered protrusion 52 formed in the case member 51, so The manufacturing efficiency of the telephone 1 can be improved.
Further, since the center of gravity of the holder member 41 on which the camera unit 17 and the vibrator 31 are mounted is located approximately in the middle of the holder member 41 in the longitudinal direction, the vibration of the vibrator 31 is evenly transmitted in the longitudinal direction of the holder member 41. can do.
In addition, since the center of gravity of the holder member 41 substantially coincides with the center portion in the width direction of the second casing 3, the vibration of the vibrator 31 can be reliably transmitted uniformly to the entire second casing 3. Can do.
Further, the two through holes 46, 47 of the holder member 41 are arranged so as to be substantially orthogonal to the rotation axis A 1 of the vibrator 31, and the holder member 41 and the second casing 3 are arranged in the through holes 46, 47. Are fixed to each other, vibration transmission from the vibrator 31 to the second housing 3 can be performed in a more balanced manner.
