The vibration generating device includes a coil configured to generate a magnetic field that causes the vibrator to vibrate. The vibration generating device includes a bracket including a coil-mounting portion on which the coil is mounted. The housing includes bracket supports provided at ends of two opposing side surfaces among the four side surfaces of the housing, the ends being situated opposite ends, of the two opposing side surfaces, to which the bottom of the housing is connected. The bracket includes connection portions bonded to the respective bracket supports. The bracket supports of the housing and the connection portions of the bracket are connected together in a state in which the bracket is inserted into a space of the housing. ## Claims ### Claim 1 A vibration generating device comprising: a housing including a substantially rectangular bottom plate and four side plates, the housing having an interior space; a vibrator including a magnet; a resilient member between the housing and the vibrator; a coil configured to generate a magnetic field that causes the vibrator to vibrate; and a bracket including a coil-mounting portion on which the coil is mounted, wherein the housing includes bracket supports provided at one ends of two side plates facing each other among the four side plates, the one ends being situated opposite the other ends, of the two side plates, to which the bottom plate is connected, wherein the bracket includes connection portions bonded to the respective bracket supports, and wherein the bracket supports of the housing and the connection portions of the bracket are connected together in a state in which the bracket is placed in the interior space of the housing. ### Claim 2 (depends on 1) The vibration generating device according to claim 1, wherein the bracket includes extending supports, each extending support being formed by bending a portion of the coil-mounting portion at a right angle, and the connection portions, each connection portion being formed by bending a corresponding extending support at the right angle, and wherein each bracket support is formed by bending a corresponding side plate at a right angle. ### Claim 3 (depends on 2) The vibration generating device according to claim 2, wherein each connection portion in the bracket is formed by bending a corresponding extending support such that a resulting bent portion extends in a vibratory direction of the vibrator, and wherein each bracket support of the housing is formed by bending a corresponding side plate such that a resulting bent portion extends in the vibratory direction of the vibrator. ### Claim 4 (depends on 2) The vibration generating apparatus according to claim 2, wherein the bracket includes two extending supports and two connection portions that are situated toward a first side plate among the four side plates of the housing, each of the two extending supports being along the vibratory direction of the vibrator, and two extending supports and two connection portions that are situated toward a second side plate opposite the first side plates among the four side surfaces of the housing, each of the two extending supports being along the vibratory direction of the vibrator. ### Claim 5 (depends on 2) The vibration generating device according to claim 2, wherein each connection portion of the bracket and a corresponding bracket support of the housing are joined by laser welding. ### Claim 6 (depends on 1) The vibration generating device according to claim 1, wherein the bracket includes extending supports, each extending support being formed by bending a portion of the coil-mounting portion at a right angle, and wherein each connection portion of the bracket is formed by bending a corresponding extending support in a direction opposite a direction in which the coil-mounting portion is provided. ### Claim 7 (depends on 6) The vibration generating device according to claim 6, wherein a width of each bracket support of the housing is greater than or equal to 1 mm and less than or equal to 2 mm, in a direction perpendicular to the vibratory direction of the vibrator.
