Abstract: The present invention discloses a speaker module. The speaker module comprises an inner cavity defined by a shell, and a first induction coil. A single speaker piece is provided in the inner cavity of the shell, the first induction coil is configured to be electrically connected with a terminal device, and a second induction coil, which corresponds to the first induction coil and is configured to be electrically connected with a voice coil in the single speaker piece, is also provided on the shell. According to the speaker module, an output end of a complete machine and the voice coil are conducted through the first induction coil and the second induction coil; and by the adoption of such a structure, the space of the module can be greatly saved, and a lighter and thinner complete machine can be developed. In addition, the problems, such as poor performance due to the change of the resistance value in a traditional electro-acoustic connection way, can be solved. By the adoption of the structure, the first induction coil is allowed to be provided outside the inner cavity, the shell can be sealed at a time, wiring from the outside to the inside is not needed any more. In this way, secondary sealing of a lead position is avoided, production and transportation of the speaker module are greatly simplified, and assembly between the speaker module and the terminal device is also greatly simplified.

Abstract: An air valve and a speaker are provided. The air valve comprises a valve body, an elastic valve plate, an air inlet penetrating through an inner surface and an outer surface of the valve body, and an air outlet penetrating through an inner surface and an outer surface of the valve plate. The valve plate is connected with the valve body in a sealing manner to form an annular sealing area encircling the air outlet and the air inlet, and the inner surface of the valve body covers the air outlet, and/or the inner surface of the valve plate covers the air inlet. The speaker is provided with or incorporates the air valve. The air valve can be opened or closed via elastic deformation of the valve plate of the air valve.

Abstract: A protective apparatus for sound-absorbing particles (4) in a sounding apparatus, comprising a housing (1) and a rear acoustic cavity formed inside the housing (1). The rear acoustic cavity is filled with sound-absorbing particles (4). A sound circulation channel (5) communicating the rear acoustic cavity with the outside is provided on the housing (1). A sound transmission layer (3) used for preventing the sound-absorbing particles (4) from being exposed covers an entrance of the sound circulation channel (5). The sound transmission layer (3) of the protective apparatus separates the sound circulation channel (5) from the rear acoustic cavity, such that airflow in the rear acoustic cavity passes through the sound transmission layer (3) and then flows out of the sound circulation channel (5). Configuration of the sound transmission layer (3) can hinder the sound-absorbing particles (4), prevent the sound-absorbing particles (4) from entering the sound circulation channel (5), and do not influence outflow of airflow. The problem in the prior art that sound-absorbing particles (4) are easily exposed or block a sound circulation channel (5) is solved, and the quality of a sounding apparatus is ensured.

Abstract: Described is an air valve and a speaker containing the air valve described. The air valve comprises a valve body, an elastic valve plate, an air inlet penetrating through an inner surface and an outer surface of the valve body, and an air outlet penetrating through an inner surface and an outer surface of the valve plate. The valve plate is connected with the valve body in a sealing manner to form an annular sealing area encircling the air outlet and the air inlet. The inner surface of the valve body covers the air outlet, and/or the inner surface of the valve plate covers the air inlet. The air valve can be opened or closed via elastic deformation of the valve plate of the air valve. Therefore, the air valve can be perfectly matched with smaller sized products, reducing the difficulty in adjusting the micro speaker in a limited space.
