Coil bobbins for balanced armature receivers are disclosed. The balanced armature receiver bobbin includes a coil support member, at least two flanges, and a shoulder. The coil support member has an armature passage extending between a first end and a second end thereof. The flanges extending radially from the coil support member such that the first flange extends from the coil support member proximate the first end and the second flange extends from the coil support member proximate the second end. The shoulder extends from the first flange, with the first flange located between the shoulder and the coil support member. The shoulder has a plurality of conductive coil pads disposed on a bottom portion thereof.

A vibration apparatus, an apparatus including the same, and a vehicular apparatus including the new vibration apparatus are provided having a simplified structure. The vibration apparatus includes a vibration portion, a first electrode portion at a first surface of the vibration portion and configured with a conductive adhesive member, and a second electrode portion at a second surface different from the first surface of the vibration portion.

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook, a core housing, and a circuit housing. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve. The protective sleeve may be made of an elastic waterproof material. The core housing may be used for accommodating an earphone core. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The circuit housing may be used for accommodating a control circuit or a battery. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate. The vibration of the earphone core may generate a driving force to drive a housing panel of the core housing to vibrate. The driving force may be not parallel to a normal line of the housing panel. In the present disclosure, the core housing may elastically abut against the protective sleeve surrounding the ear hook to improve the overall waterproof effect of the loudspeaker apparatus and simplify the manufacturing and assemble process of the loudspeaker apparatus.

A mounting structure includes: a first substrate that has a first surface on which a functional element is provided; a wiring portion that is provided at a position, which is different from a position of the functional element on the first surface, and is conductively connected to the functional element; a second substrate that has a second surface that is opposite to the first surface; and a conduction portion that is provided on the second surface, is connected to the wiring portion, and is conductively connected the functional element. The shortest distance between the functional element and the second substrate is longer than the longest distance between the second substrate and a position where the wiring portion is connected to the conduction portion.

An electronic module can include a first housing defining a housing cavity, the first housing defining a first end and a second end positioned opposite from the first end, the first end defined by a shaft of the first housing, the shaft defining external threading, the first housing defining a housing opening to the housing cavity at the second end; an LED lamp board positioned within the housing cavity, the LED lamp board configured to emit light through the housing opening; a power supply driving module positioned within the housing cavity at least partially between the LED lamp board and the shaft; and a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending at least partially through the shaft, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal.

A method for manufacturing a loudspeaker having a wire damper with locally adjustable elasticity, including preparation, impregnating, drying, wire disposing, forming, cutting and assembling steps. Wherein, a wire damper including a main body and a wire is thermoformed on a base material. The main body includes a wave structure and a wire disposing area. The wave structure includes wave crest and trough, and inner and outer sidewalls. The wire disposing area forms a hollow portion in which the wire extends. The warp yarns at outside and inside of the wire disposing area form an elastic adjustment area. The hollow portion has smaller depths at the inner and outer sidewalls than at the wave crests and troughs. Thereby, the wire will not be damaged by hot pressing, and the hardness, elasticity and toughness of the combination of the wire disposing area and the wire are equal to that of other areas.
