The present invention provides a speaker structure, comprising a vibrating component, an electromagnetic component, an casing and an integral washer conductive sheet. The electromagnetic component comprises a central magnet and peripheral magnets which are disposed around the central magnet. The integral washer conductive sheet replaces a washer structure and an conductive sheet structure in a traditional speaker structure and is integrally formed by the washer and an conductive sheet which are combined into one part. The integral washer conductive sheet comprises a washer part and an conductive sheet part, wherein the washer part is disposed on the peripheral magnets and the conductive sheet part extends out of the casing. By adopting the integral washer conductive sheet according to the present invention, those skilled in the art can simplify an internal structure of the speaker, save production materials, simplify molding and assembling procedures, and improve production efficiency.

A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.

A mobile terminal is provided. The mobile terminal includes: a receiver, disposed on one side of a center line of the mobile terminal, where a sound outlet hole is provided in a display screen of the mobile terminal, a front cavity sound outlet channel of the receiver is provided inside the mobile terminal, and the front cavity sound outlet channel communicates with the sound outlet hole; and a through-hole is provided at the top of the mobile terminal, and the through-hole communicates with the front cavity sound outlet channel.

There is provided an electrodynamic sound transducer comprising a chassis and at least one diaphragm which is capable of vibrating and which at its edge has at least two oppositely disposed fixing portions for fixing the diaphragm to the chassis. The edge of the diaphragm is not connected to the chassis between the fixing portions so that the diaphragm can vibrate freely at those locations.

A housing for a communication device comprises a first housing section with a membrane opening, wherein the first housing section comprises around the circumference of the membrane opening a first membrane support configured to couple to a sound membrane, and a magnet carrying support, which is integrally formed with the first housing section and is configured to support a magnet in the housing and below the membrane opening. Furthermore, the present invention provides a communication device.

A multi-input-driving loudspeaker including a frame, a diaphragm arranged on the frame, and a plurality of input driving mechanisms. Each input driving mechanism includes a voice coil and a magnetic circuit assembly for driving the voice coil to vibrate. A plurality of magnetic circuit mounting holes are arranged on the frame. A plurality of voice coil mounting holes are arranged on the diaphragm. Each of the input driving mechanisms further includes a damper. Each of the voice coils is sleeved with one of the dampers. The frame has a plurality of flanges surrounding the magnetic circuit mounting holes. Each of the dampers and each of the flanges cooperate with each other so that each damper is embedded between an inner walls of the flange corresponding therewith.

An object is to provide a speaker device in which vibrations generated from a vibration device can be efficiently transmitted to a diaphragm, and thus sound volume can be secured and clear sound with a wide range can be produced. A speaker device 1 is a device in which a vibration device 3 is brought into contact with one flat surface of a diaphragm 2, and the device emits vibrations transmitted through the vibration device 3 from the diaphragm 2 as sound. The speaker device 1 includes: the diaphragm 2; the vibration device 3; a frame body 4 provided to the diaphragm 2 so as to surround the vibration device 3; and an elastic body 5 provided facing the flat surface of the diaphragm 2 with the frame body 4 and the vibration device 3 interposed therebetween. The frame body 4 is provided with a gap interposed between itself and an outer circumference of the vibration device 3. The elastic body 5 is laid across the frame body 4 and the vibration device 3, and fastened to the frame body 4 and the vibration device 3. The frame body 4, the vibration device 3, and the elastic body 5 are integrated with each other.

An electronic device comprises a housing including a window member facing a first direction, a rear housing facing a second direction that is opposite to the first direction, and a side member encompassing the space between the window member and the rear housing. The electronic device also includes a display that is visible through at least a part of the window member and a speaker assembly disposed in the space. The speaker assemble includes a speaker diaphragm. The side member includes a resonance space including a shape a recessed form in a third direction that is substantially perpendicular to the first direction or the second direction. A through hole is formed in the third direction in a part of the resonance space that is closer to the rear housing than to the window member. A part of the resonance space can be disposed so as to overlap the speaker diaphragm.

A vibration generation apparatus includes a concave frame, a vibrator, and a first damper. The frame has an opening in upper portion thereof. The vibrator is housed in the frame. The first damper is connected to the vibrator and the frame and is configured to hold the vibrator such that the vibrator is able to move in an up-down direction with respect to the frame. The first damper has a predetermined thickness. The first damper is in an N-shape in a side view and includes two bent portions and has an upper end mounted on an edge of the opening and a lower end mounted on a lower edge of the vibrator.
