摘要:
The present invention discloses a portable Karaoke system. The portable Karaoke system has a separate radio auxiliary microphone receiving module and a separate FM transmission module, which can be inserted/separated into/from the portable Karaoke system, such that a user can select and purchase only a required function module and easily carry and keep the portable Karaoke system. The portable system has hooks, which are provided at both sides of a battery case to prevent a battery from being easily separated from the battery case, and semicircular recesses, which are formed at the top edges of both sidewalls of the battery case to allow a user to easily remove the battery from the battery case. Furthermore, the portable Karaoke system has first and second gears formed at stepped portions of the end of a microphone body such that the first gear is combined with a general microphone and the second gear is combined with a ball-type microphone net.

The image sensor and an image sensing system including the same are provided. The image sensor includes a semiconductor substrate, a pixel array formed at a pixel area located in the semiconductor substrate and comprising a plurality of photoelectric converts, a plurality of driver circuits formed at a circuit area defined in the semiconductor substrate. The image sensor includes at least one heat blocker or heat shield. The at least one heat blocker may be formed between the pixel area and the circuit area in the semiconductor substrate. The heat blocker or heat shield may block or dissipate heat generated at the circuit area from being transferred to the pixel area through the semiconductor substrate. The heat blocker or heat shield may be used in image sensors using a back-side illumination sensor (BIS) structure or image sensors using a silicon on insulator (SOI) semiconductor substrate.

Provided are a chip, a chip stack, and a method of manufacturing the same. A plurality of chips which each include: at least one pad formed on a wafer; and a metal layer which protrudes up to a predetermined thickness from the bottom of the wafer and is formed in a via hole exposing the bottom of the pad are stacked such that the pad and the metal layer of adjacent chips are bonded. This leads to a simplified manufacturing process, high chip performance and a small footprint for a chip stack.

There is provided a microphone type music accompaniment playing (karaoke) system including: a memory section for storing a plurality of still and motion pictures; and a controller for, in Auto mode, combining the stored still and motion pictures of the memory section with each music accompaniment and sending the still or motion pictures selected in combination with the music accompaniment as a background image to an external display panel, or, in Select mode, sending both a music accompaniment signal and one of the still or motion pictures of the memory section as selected by a user as a background image to the external display panel. The microphone type music accompaniment playing (karaoke) system provides, in combination with a user' selected song, images of the original singer of the song and the song-related background images, thus fascinating users and greatly enhancing the demand for music accompaniment playing (karaoke) equipment.
