Electronic device having a removable battery pack assembly

An electronic device comprising:

• (a) a battery pack including:
• (1) a battery holder shaped for receiving a battery having first and second terminals, the battery holder having an opening at one end and a base at the other end and at least one internal longitudinal groove extending from the base to the opening;
• (2) a contactor having an elongated flexion spring located inside the battery holder between the base of the battery holder and the battery for biasing the battery toward the opening of the battery holder, the spring having respective ends in contact with the base of the battery holder and a resiliently bowed center portion for electrically contacting the first terminal of the battery, and at least one contact connected with one end of the spring for electrical connection with the first terminal of the battery, the contact extending outside the opening of the battery holder for electrical connection, the contact being recessed within the longitudinal groove of the battery holder to provide clearance for the battery;
• (3) at least one lug connector positioned externally on the battery holder for removably mounting the battery pack to the electronic device;
• and
• (4) a retaining ring mounted at the opening of the battery holder for retaining the battery inside the battery holder against the bias of the spring, the retaining ring having a central aperture through which the second terminal of the battery is exposed at the opening of the battery holder for electrical connection, the retaining ring having at least one contact passageway at an outer periphery of the retaining ring to permit the contact to pass therethrough;
• and
• (b) a housing including a receptacle for the battery pack, the receptacle having an open end and a base end and at least one internal guide groove including an angled section to guide the lug for transverse and longitudinal movement of the battery pack within the receptacle to permit insertion of the battery pack into the receptacle and an adjoining transverse section to permit the battery pack to be moved within the receptacle to hold the battery pack in position, the receptacle including a detent along the guide groove for cooperation with the connector lug of the battery pack to retain the battery pack in position within the receptacle and a receptacle contact positioned at the base end of the receptacle for electrical connection to the second terminal of the battery, the receptacle contact engaging the second terminal of the battery thereby causing the spring of the contactor to yield so that the lug connector may be positioned within the guide groove to retain the battery pack in position within the receptacle.

An electronic device comprising:

• (a) a housing having an interior and a receptacle for a power source;
• (b) guide rails on the interior of the housing;
• and
• (c) a speaker holder for holding a speaker in the housing for connection with the power source to produce an audible sound, the speaker holder having a speaker-holder compartment for capturing and retaining the speaker, the speaker-holder compartment being slidably mountable on the guide rails in the interior of the housing to hold the speaker in position and the speaker-holder compartment being slidably removeable from the housing on the guide rails.
