摘要:
A cluster key arrangement may be mechanically configured or electronically configured. The cluster key arrangement may include twelve cluster keys configured in an arrangement of three columns by four rows, such as conventionally found on standard telephones. The cluster key arrangement may also be configured for use or cellular/mobile telephones, television remote controls, other handheld data entry devices, automotive controls, desktop/wall-mounted/cordless telephones, combination telephone recorders, Personal Digital Assistants, and other electronic devices. The mechanically or electronically configured cluster, keys provide a user with the ability to select one of a plurality of key elements representing numbers, letters, symbols, functions, etc., in a mutually exclusive manner.

Provided are an earphone device in which a cable configured to be able to respond in a wide range to press and having switch functions is applied to an earphone to make it easy even for a user who uses the earphone device for the first time to operate the earphone device, and which includes switch parts in three places, so that these three parts are selected and pressed as appropriate when necessary, thereby allowing desired operations to be easily performed, is less liable to false operation, and eliminates the need to, for example, indicate operating ranges, and a sound-reproducing system using this earphone device. The earphone device is provided with a first earphone body in which an electro-acoustic transducer is built; a first cable one end of which is connected to this first earphone body and within which a switch member to be turned on by one-way press is disposed over a predetermined range along the length direction of the cable so that the cable has switch functions; a second earphone body in which an electro-acoustic transducer is built; and a second cable one end of which is connected to this second earphone body and within which a switch member to be turned on by one-way press is disposed over a predetermined range along the length direction of the cable so that the cable has switch functions, wherein a switch is shunted into two switches by the first and second cables, the first and second cables are arranged one on top of the other, and an overlapped portion is unidirectionally pressed to simultaneously turn on the switches. In addition, a sound-reproducing system is configured by combining a mobile terminal which operates in conjunction with this earphone device.

A keypad comprises a keypad frame and a metal spacer disposed on a backside thereof. At least one metal fret having a plurality of metal standoffs is disposed amongst the corresponding keycaps. These metal standoffs connect to the metal spacer (for example, via laser welding). The keypad frame can include a plurality of registration components and the metal spacer can include corresponding registration component-receiving openings disposed therein.

A key/display assembly (108) includes first and second switch (216B)es, a display module (212), and a lens (122) is disposed adjacent the display module (212). The lens (122) includes a first contact region (226A), a second contact region (226B), and an inner surface that supports a first foot (234A) between the first contact region (226A) and the second contact region (226B). A first key (120A) is defined by the first switch (216A) and the first contact region (226A) and is actuated by deflecting the first contact region (226A) to actuate the first switch (216A). A second key (120B) is defined by the second switch (216B) and the second contact region (226B) and is actuated by deflecting the second contact region (226B) to actuate the second switch (216B). When actuating the first key (120A), the first foot (234A) inhibits the second contact region (226B) from actuating the second switch (216B). When actuating the second key (120B), the first foot (234A) inhibits the first contact region (226A) from actuating the first switch (216A).
摘要:
The invention relates to an electrical key switch comprising a printed circuit board with multiple switch contacts and a reference trace that are normally electrically isolated from each other, and a metal snap dome disposed above the printed circuit board, and having an outer edge in electrical contact with a reference trace, the dome having an elevated central region forming a downwardly facing cavity defined at its edge by a ridge disposed above the switch contacts, such that when the snap dome is actuated the ridge about the central region engages the printed circuit board in an annular contact zone across the switch contacts, making electrical contact between the snap dome and the switch contacts to electrically connect the switch element with the multiple switch contacts.
摘要:
A keypad with both elevated (11) and non-elevated (22) key regions, and key switches (12) disposed beneath both types of key regions. The non-elevated key regions each provide corresponding character output based on an operation algorithm that considers activation of at least one adjacent elevated key region as well as activation of the switch below the non-elevated key region. The keypad includes a keymat (41) that is rigidly held at its perimeter in a stretched condition across a switch substrate (23). The key switches include metal snap domes (12) that have an elevated central region (212) forming a downwardly facing cavity (13) defined at its edge by a ridge (214) disposed above the switch contacts (21) that electrically engages multiple switch contacts in an annular contact zone (230).
摘要:
A keypad has both hill keys (12) that provide a corresponding output when individually pressed, and valley keys (14) are labeled to correspond with an output that results at least from the simultaneous or near-simultaneous manipulation of a predetermined set of two or more hill keys (12) adjacent the valley key (14). Pairs of hill keys (12) are joined to form elongated dual keys (16) that provide a nominal effective key width (H) substantially equal to a nominal effective key width (V) of the valley keys.
