It is to provide a light source module capable of downsizing an edge-light type backlight in thickness and reducing the usage amount of resin. A method of manufacturing a light source module includes a process of preparing a substrate with a first reflector including a reflecting surface mounted thereon, a process of mounting a plurality of light emitting elements on the substrate, a process of mounting a wiring board having an electrode on the substrate, a process of connecting the electrode of the light emitting element and the electrode of the wiring board with metal wire, a process of mounting a second reflector having a reflecting surface on the wiring board, and a process of filling the space between the first reflector and the second reflector, with resin.

Light source module

An edge light display unit includes light generating sources, a substrate mounting the light generating sources, a lens, a diffusion plate expanding light input in a side surface of the diffusion plate as to irradiate a front surface of the diffusion plate, and a heat sink thermally contacted with the substrate. A base portion of the heat sink has a substrate mounting surface and a fin constituting surface substantially perpendicular to the substrate mounting surface. At least one fin extends from the fin constituting surface in a direction substantially perpendicular thereto and along the plurality of light generating sources in a direction parallel to substrate. An air supply and exhaust surface of a cooling air are formed in a back surface side of the display unit.

Conventionally, there is a description about stereophonically reproducing downloaded musical pieces or those stored on a memory card. A call speech is supported in monaural only. A realistic telephone call using stereo sound has been unavailable. The present invention aims at providing a cellular phone capable of a telephone call using stereo sound. The cellular phone terminal capable of speech communication with another information processing terminal. The cellular phone terminal is configured to comprise: a plurality of speakers for the speech communication; a receiver to receive a speech signal from a plurality of microphones of the other information processing terminal; and a processor to provide control so that the plurality of speakers can output the speech signal received by the receiver.
