A receiver comprises a peripheral housing, and a magnet circuit system and a vibrating system. The vibrating system comprises a vibrating diaphragm and a voice coil. The periphery housing comprises a first and second housing matched with each other, which are provided with electrical connection structures conductive with each other. A sidewall of the first housing is provided with a first elastic piece including one end welded with a spring electrically connected to an external circuit and another end exposed at the outer side of the sidewall of the first housing. A sidewall of the second housing is provided with a second elastic piece including one end electrically connected with a lead wire of the voice coil and another end exposed at the outer side of the sidewall of the second housing and welded and fixed with a portion of the first elastic piece exposed to the outer side.

The present invention relates to the technical field of electroacoustic products. Disclosed is a miniature speaker. The miniature speaker comprises an upper housing and a lower housing combined together. A vibration system and a magnetic circuit system are accommodated in the space defined by the upper housing and the lower housing. The upper housing is disposed close to the vibration system. The miniature speaker also comprises a hearing-aid voice coil. The hearing-aid voice coil is fixed to the upper housing and is located at the inner side of the upper housing. The miniature speaker of the present invention solves the problem of poor acoustics caused by collision of a lead wire of a vibrating voice coil with a hearing-aid voice coil of a miniature speaker in the prior art, and the miniature speaker of the present invention has good acoustic performance and a better hearing-aid effect.

A receiver is provided comprising an outside housing, and a magnetic circuit system and a vibration system accommodated in the outside housing. The vibration system comprises a vibration diaphragm and a voice coil. The outside housing comprises a first housing and a second housing matching with each other. The first housing and the second housing are provided with electrical connection structures conductive to one another thereon. The first housing is provided with a first elastic piece on a sidewall thereof. One end of the first elastic piece is welded with a spring electrically connected to an external circuit, and the other end is exposed at the outside of the sidewall of the first housing. The second housing is provided with a second elastic piece on a sidewall thereof. One end of the second elastic piece is electrically connected to a lead wire of the voice coil, and the other end of the second elastic piece is exposed at the outside of the sidewall of the second housing and is welded and fixed with the portion of the first elastic piece exposed at the outside. The receiver of the present utility model can reduce the lateral dimension of a product without impairing the performance of the product, and can satisfy the restrictive requirement on the lateral dimension of the product when assembled with a terminal electronic device.

A loop antenna for a mobile device is disclosed. The loop antenna includes a permanent magnet structure, for accommodating a permanent magnet inside the mobile device, a housing for accommodating the permanent magnet structure, and an antenna pattern unit mounted in the housing, surrounding an outer periphery of the permanent magnet.

In one embodiment, an apparatus comprises i) an audio transducer; ii) an audio driver plate having an ear-facing side and a non-ear-facing side; iii) a rigid housing substantially circumferentially surrounding the audio driver plate without substantially covering the ear-facing side and non-ear-facing side of the audio driver plate; iv) a front plate mounted on the ear-facing side of the audio driver plate and spaced apart from the audio driver plate; and v) a fixing gasket affixed to the non-ear-facing side of the audio driver plate. In addition, the front plate is adapted to be compressed against an ear-facing portion of an audio transducer holding device and the fixing gasket adapted to be compressed against a non-ear-facing portion of the audio transducer holding device, whereby the audio transducer is adapted to be held within the audio transducer holding device by compressive force on both the fixing gasket and the front plate.
