Abstract
A control pad structure (10) with a built-in speaker (40) includes a circuit board (20) disposing a plurality of touch switches (22) thereon; a control pad (30) is provided with a plurality of bulge points (36); and an accommodating space (35) is formed between the circuit board and the control pad for enclosing the speaker therein. The speaker is also provided with a bulge point. When the control pad is operated, the bulge points engage with corresponding touch switches to activate the switches. A plurality of openings (24) is defined in the circuit board between the touch switches.
Claims20
A control pad structure comprising:
- a circuit board with a plurality of first touch switches and a second touch switch disposed thereon, the second touch switch being located at a center of the plurality of first touch switches and surrounded by the plurality of first touch switches;
- a control pad with a plurality of first bulge points corresponding to the plurality of first touch switches of the circuit board, the control pad being located above and spaced apart from the circuit board;
- an accommodating space formed between the circuit board and the control pad;
- and
- a speaker received in the accommodating space and having a second bulge point at a center of a bottom thereof corresponding to the second touch switch.
A control pad structure configured for being mounted to a casing, the control pad structure comprising:
- a circuit board having a plurality of first touch switches and a second touch switch disposed thereon, the second touch switch being located at a center of the plurality of first touch switches and surrounded by the plurality of first touch switches;
- a control pad comprising a main body, and a plurality of spaced legs extending from the main body;
- an accommodating space enclosed between the main body and the plurality of legs;
- and
- a speaker received in the accommodating space above the circuit board;
- wherein the plurality of legs each have a first bulge point extending therefrom for contacting the plurality of first touch switches of the circuit board, and the speaker has a second bulge point extending therefrom for contacting the second touch switch of the circuit board.
A hand-held electronic device comprising:
- a casing;
- a display on the casing;
- a plurality of data keys on the casing;
- a circuit board in the casing, the circuit board being provided with a plurality of first touch switches and a second touch switch thereon, the second touch switch being located at a center of the plurality of first touch switches and surrounded by the plurality of first touch switches;
- a multi-way function key on the casing, comprising a main body defining a plurality of through holes therein, a plurality of legs extending downwardly from the main body toward the circuit board, a channel between two neighboring ones of the plurality of legs, and an accommodating space surrounded by the plurality of legs;
- and
- a speaker received in the accommodating space above the circuit board;
- wherein the legs have first bulge points formed on bottoms thereof for activating the first touch switches of the circuit board and the speaker has a second bulge point extending therefrom for contacting the second touch switch of the circuit board when the multi-way function key is operated.
