Abstract: A speaker unit that can prevent a lead from being broken is provided. The speaker unit includes: a diaphragm; a voice coil which is secured to the diaphragm; and a lead which is connected to the voice coil to energize the voice coil. The diaphragm includes an annular securing portion which has the voice coil secured thereto, and an outer projection which projects with respect to the securing portion at a side corresponding to a surface of the diaphragm having the voice coil secured thereto and extends along the securing portion. The outer projection has a top. The outer projection has the top partially recessed to have a recess. The lead extends across the recess to traverse the outer projection.

Abstract: A speaker has a speaker unit and a box. The speaker unit has a speaker unit side terminal. The box includes a casing having an internal space, and a box side terminal arranged in the casing so as to be in close contact with the casing. Under the condition that the speaker unit is housed in the internal space, a first terminal serving as one of the speaker unit side terminal and the box side terminal has a projection, a second terminal serving as the other thereof surrounds and sandwiches an outer periphery of the projection from at least both sides, and the first terminal and the second terminal are electrically connected with soldering. Thus, it is possible to obtain the speaker which can improve workability on a connection between the speaker unit and the box and save a space, and the portable information terminal provided with the speaker.

Abstract: A speaker terminal mount structure has a frame having a slit, and a terminal supported by the frame when inserted into the slit. The slit has a shape including two first side support sections, and at least one second side support section abutting on a second surface and positioned on an inner side of a region sandwiched between the two first side support sections when viewed from a direction in which the terminal is inserted. Assuming that a first virtual straight line is formed by connecting the two first side support sections, and a second virtual straight line extends in parallel to the first straight line at a distance smaller than a thickness of the terminal from the first straight line in a first direction, the second side support section is positioned in a second direction with respect to the second straight line.
