Abstract

PURPOSE:To obtain a speaker unit excellent in water-proof and moisture-proof in terms of both material and structure by forming a diaphragm and a voice coil bobbin by a plastics integrally and inserting a voice coil winding to the voice coil bobbin. CONSTITUTION:A cone type diaphragm 12 is formed integrally from one end of the voice coil bobbin 11 by a plastics. The voice coil 13 with winding is insert-formed to the voice coil bobbin 11 at its integral forming, both ends of the voice coil 13 are lead wires 13A of gold thread function and led to the outside from the voice coil bobbin 11 and connected to a terminal 14 provided to a speaker frame 21 via the diaphragm 12. The voice coil 13 inserted to the voice coil bobbin 11 is placed in the air gap of a magnetic circuit 22 and the inner circumferential ridge of a damper 23 of doughnut shape is fixed to one end of the voice coil bobbin 11 and the outer circumferential ridge of the damper 23 is fixed respectively to the speaker frame 21. Thus, structural water- proof is given and water-proof performance is provided also to the diaphragm 12.

Description

【発明の詳細な説明】[Detailed description of the invention] 【産業上の利用分Ｗｌ この発明は防水型スピーカユニットに関し、さらに詳しくは、プラスチックス成形により防水性を向上させた防水型スピーカユニットに関する。 【従来の技術】[Industrial usage Wl The present invention relates to a waterproof speaker unit, and more particularly to a waterproof speaker unit whose waterproof properties are improved by molding plastics. [Conventional technology]

In these figures, reference numeral 11 indicates a voice coil bobbin, and a cone-shaped diaphragm 12 is integrally molded from one end of the voice coil bobbin 11 from plastic. In particular, the voice coil 13 is pre-wound when the voice coil bobbin 11 is integrally molded, and is then insert-molded.
Both ends of the voice coil 13 are conductive wires 13 having a tinsel wire function.
A is led out from the voice coil bobbin 11 and connected to a terminal 14 provided on the speaker frame 21 with all the IAm plates 12 . In these figures, the reference numeral 22 indicates the speaker frame 2.
The voice coil 13 inserted into the voice coil bobbin 11 is located in the air gap of the magnetic circuit 22, and one end of the voice coil bobbin 11 has a donut shape. The inner peripheral edge of the damper 23 is fixed, and the outer peripheral edge of the damper 23 is fixed to the speaker frame 21, respectively. Alternatively, the voice coil 13 may be wound around the outside of the voice coil bobbin 11, and the conducting wire 13A may be guided onto the cone diaphragm 23 and connected to the terminal 14 (FIG. 3).
