A sound-emitting jigsaw puzzle includes a base on which a control unit is mounted to receive signals from a key unit and to emit a specific sound via a speaker according to the signals from the key unit. The key unit includes a face panel, below which an upper and a lower circuit-contained film sandwiching an isolating film between them are provided. A plurality of equally spaced contacts are provided on the upper and the lower films to form a dot matrix when the two films are fully overlapped with each other. The isolating film is provided with a plurality of through holes corresponding to contacts on the upper and the lower films. The face panel is made of a high durometer foam rubber and has a lower surface provided with a plurality of keys corresponding to the contacts. When any area of the face panel is depressed, a key below the area is moved downward to cause corresponding contacts on the upper and the lower films to electrically contact with one another via the through hole on the isolating film and a specific sound is emitted. The sound-emitting jigsaw puzzle has low profile and may have increased number of contacts by reducing the interval between the contacts.
