Embodiment Construction

[0025] In its most general aspect, the invention relates to a suspension member made of an elastic material such as silicone. The elastic properties of elastic materials can be exploited to provide a means of compensating for manufacturing tolerances, especially compensating for assembly tolerances.

[0026] FIG. 1 a shows a prior art device comprising a piston 101 connected to a suspension member 103 . The suspension member 103 is fixed to the transducer frame 102 and to the front frame, which is generally divided into a lower part 104 and an upper part 105 . A foam layer 106 is provided on top of the upper portion 105 of the front frame. The foam 106 provided in a separate process step is adapted to form an acoustic seal between the transducer and the cover of the device housing the transducer, in order to avoid acoustic shorting of the transducer, i.e. air pushed by the piston 101 Leakage to the backside of the transducer. An effective acoustic seal will ensure that acou...

Abstract

The present invention relates to a suspension member for suspending a moveable piston structure of a transducer, the suspension member comprising tolerance compensation means comprising an elastomeric material, said tolerance compensation means being formed as a structure extending in a direction so as to form an acoustical seal between a first chamber and a second chamber.

Description

technical field [0001] The present invention relates to a suspension member for a transducer such as a microspeaker. In particular, the present invention relates to a resilient suspension member having a sealing member attached thereto or integrated therein. Background technique [0002] It is well known that in the process of assembling compact devices (eg, phones, tablets, game consoles, laptops, etc.), manufacturing and assembly tolerances are considered necessary to ensure proper acoustic performance of the final device. In particular, proper mounting of prefabricated miniature transducers (eg, microspeakers) is important to the overall acoustic performance of such compact devices. [0003] Prefabricated miniature transducers are typically constructed to be electrically connected to a supporting printed circuit board (PCB) using a spring-based connection structure. Alternatively, prefabricated miniature transducers may be configured as surface mount devices (SMDs), ie ...
