摘要： The present disclosure provides a speaker diaphragm and a speaker. The diaphragm includes two surface layers compounded together and at least one intermediate layer located between the two surface layers, at least one of the surface layers is a thermoplastic polyester elastomer film layer, and at least one of the intermediate layers is au adhesive layer, wherein the thermoplastic polyester elastomer film layer has a Young's module of 1-1000 MPa, a loss factor being greater than or equal to 0.015, and an elastic recovery rate after 10% strain being greater than or equal to 80%. The speaker diaphragm may be made very thin, thus reducing the weight of the speaker diaphragm, improving the space allowance for vibration, improving the sensitivity, and making the F0 of the speaker lower. Further elastic area of the speaker diaphragm is wider and the resilience performance is excellent.

摘要： A speaker diaphragm includes a first polymer and a second polymer. The first polymer and the second polymer undergo phase separation. The first polymer is a polyolefin, and the second polymer is a thermoplastic resin being immiscible with the polyolefin. One of either the polyolefin or the thermoplastic resin constitutes a sea phase, and another one of either the polyolefin or the thermoplastic resin constitutes island phases being interspersed in the sea phase.

摘要： An acoustic apparatus includes an anchored diaphragm that is actuated by mechanical energy and a transduction material that is disposed in the anchored diaphragm that generates the mechanical energy that actuates the anchored diaphragm. The acoustic apparatus further includes an extendable diaphragm that is actuated when the anchored diaphragm is actuated and a plurality of damping holes that are disposed about the extendable diaphragm and that allow the extendable diaphragm to actuate in a vertical direction.

摘要： A speaker and like manufactured item manufacturing system, apparatus and method for aligning speaker components regardless of feature size to a common centering datum for placement. A speaker motor assembly may be aligned based on datum of a basket/washer subassembly, wherein remaining components are coupled, aligned and adhered according to the same datum, thus increasing concentricity, alignment, and orthogonality among components and installations. Speaker suspension components may likewise be coupled using the same datum. Specialized alignment mechanisms, such as a centering collet and a mechanical gripper, may be also be provided to align speaker components for placement and adhesion, and adhesives may be robotically controlled based on the aforementioned datum.

摘要： The present disclosure provides a transistor acoustic sensor element and a method for manufacturing the same, an acoustic sensor and a portable device. The transistor acoustic sensor element comprises a gate, a gate insulating layer, a first electrode, an active layer and a second electrode arranged on a base substrate, wherein the active layer has a nanowire three-dimensional mesh structure and thus can vibrate under the action of sound signals, so that the output current of the transistor acoustic sensor element changes correspondingly. Since the active layer having the nanowire three-dimensional mesh structure can sensitively sense weak vibration of acoustic waves, the sensitivity to sound signals of the transistor acoustic sensor element is improved.

摘要： The present invention discloses a speaker having a frame, a vibrating system and a magnetic circuit system both fixed on the frame. The magnetic circuit system having a yoke fixed on the frame. The speaker further includes a suspension having a first fixing portion fixed with the frame. The first fixing portion includes a main body portion located in the middle of the first fixing portion and a welding pad portion formed by bending from two opposite ends of the main body portion toward a direction away from both the main body portion and the yoke. The frame includes a first surface connected to the first fixing portion and an avoiding portion formed by recessing from the first surface toward a direction away from the yoke. The welding pad portion is accommodated in the avoiding portion. A total height of the spealer is reduced.

摘要： A method of forming a device having a compliant member includes applying heat to a thermoplastic elastomer to maintain the thermoplastic elastomer in a softened state. The thermoplastic elastomer is extruded in the softened state as a film of thermoplastic elastomer. One or more of a bobbin and a housing, each having and end, is positioned such that the end extends at least partially into the film of thermoplastic elastomer. The positioning occurs when the thermoplastic elastomer is in the softened state and/or the bobbin and/or housing is at a temperature that is greater than a temperature of the film of thermoplastic elastomer. The film is cooled so that the bobbin and/or housing are secured to the film and so that the thermoplastic elastomer is in a state that exhibits rubber-like properties.
