a top clamp slidably installed in the housing for permitting the top clamp to move up and down in the housing, the top clamp securing a top of the portable electronic device when the portable electronic device is installed in the cradle, the top clamp comprising at least one leg slidably installed in the housing for moving the top clamp up and down with respect to the housing; and

a height-adjust release button installed on the housing for permitting the top clamp to be raised when the height-adjust release button is actuated, wherein adjustment of the height of the top clamp is controlled by a ratchet, the ratchet comprising a set of teeth fixed to the leg and a spring-loaded pawl engaging with the set of teeth such that the leg of the top clamp is permitted to be lowered and is prevented from being raised when the spring-loaded pawl engages the set of teeth.

10. The cradle of claim 9 , wherein the height-adjust release button separates the set of teeth from the spring-loaded pawl when the height-adjust release button is actuated, thereby permitting the top clamp to be raised.

11. The cradle of claim 10 , wherein the leg of the top clamp has a spring wrapped around it for urging the leg upward, thereby urging the top clamp upward and raising the top clamp when the height-adjust release button is actuated.

12. The cradle of claim 9 , further comprising:

a protruding support installed on a front of the housing and protruding out from the front of the housing for supporting a back side of the portable electronic device when the portable electronic device is installed in the cradle; and

a protruding adjuster installed on the housing for adjusting the degree to which the protruding support protrudes out of the housing.

13. The cradle of claim 9 , further comprising a speaker chamber installed in the housing for enclosing a speaker of the cradle.

14. The cradle of claim 9 , wherein the male electrical connector is formed on the bottom of the housing, and the cradle further comprises a bottom support surrounding the male electrical connector for supporting the portable electronic device when the female electrical connector of the portable electronic device establishes electrical connection with the male electrical connector.

15. The cradle of claim 14 , wherein the bottom support is made out of rubber material.

16. A cradle for receiving a portable electronic device installed in the cradle, the cradle comprising:

a housing;

a top clamp slidably installed in the housing for permitting the top clamp to move up and down in the housing, the top clamp securing a top of the portable electronic device when the portable electronic device is installed in the cradle, and the portable electronic device making contact with the housing at two or more points for securing the portable electronic device within the cradle;
