Broadband haptic system

A trackpad of a controller, the trackpad comprising:

• a cover;
• a circuit board disposed behind the cover and coupled to the cover;
• a haptic actuator mounted to the circuit board and configured to vibrate, wherein the haptic actuator has a first resonant frequency;
• and
• a spring disposed behind the cover, coupled to the cover, and configured to be mounted to a housing of the controller, wherein the spring is further configured to deflect bidirectionally in response to a vibration of the haptic actuator, and wherein the spring comprises:
• a first elongate spring arm that is adjacent to a first side of the cover and adjoins a body of the spring at a first neck region;
• and
• a second elongate spring arm that is adjacent to a second side of the cover opposite the first side of the cover and adjoins the body of the spring at a second neck region,
• wherein the trackpad has a second resonant frequency different than the first resonant frequency.

A controller comprising:

• a housing;
• and
• a control configured to be operated by a finger, the control comprising:
• a cover;
• a circuit board disposed behind the cover and coupled to the cover;
• a haptic actuator mounted to the circuit board and configured to vibrate, wherein the haptic actuator has a first resonant frequency;
• and
• a spring disposed behind the cover, coupled to the cover, and mounted to the housing, wherein the spring is configured to deflect bidirectionally in response to a vibration of the haptic actuator, and wherein the spring comprises:
• a first elongate spring arm that is adjacent to a first side of the cover and adjoins a body of the spring at a first neck region;
• and
• a second elongate spring arm that is adjacent to a second side of the cover opposite the first side of the cover and adjoins the body of the spring at a second neck region,
• wherein the control has a second resonant frequency different than the first resonant frequency.
