Description

MICROPHONE
Technical Field
The present invention relates to a microphone, and more particularly, to a microphone capable of reducing an error rate of components and lengthening its lifetime by firmly fixing a cable, a jack holder and a phone unit onto a microphone body.
Background Art
In general, a microphone is abbreviated to a mike, and in a broad sense, also a transmitter of a telephone set belongs to the microphone. Recently, various methods for improving quality of sound in broadcasting and recording have been developed, and compact microphones of high performance using a semiconductor have been practically used. One of the microphones includes a container, which is formed to easily receive sound waves and contains a circuit vibrating by the sound waves and converting the mechanical vibration into electrical signal, a compact and solidified (or IC) amplifier and an electric battery therein. There is also a wireless microphone, and generally, a circuit of the wireless microphone in itself forms a part of a compact frequency-modulated(FM) transmission circuit. For an example, a conventional mike will be described as follows. As shown in FIGS. 1 through 3, the conventional mike includes a tubular body 10, a phone unit 12 connected to an end of the body 10, a mike cover 14 covering the phone unit 12, a connection adapter 16, a jack adapter 18 and a jack holder 20 connected to the other end of the body 10, and a cable 22 inserted into the body 10 through a hollow part 20a of the jack holder 20 and connected to the jack adapter 18. Here, the body 10 and the phone unit 12 are connected to each other with an adhesive, and the connection adapter 16 and the body 10 are connected with each other by fastening a connection hole 16a of the connection adapter 16 and a through hole 10a of the body 10 corresponding to the connection hole 16a with fastening means 24.
I
A hook 18a of the jack adapter 18, which is terminal-connected with the connection adapter 16, is inserted and fit into a hole 10b of the body 10, and the jack adapter 18 and the jack holder 20 are connected to each other by fastening a connection hole 18b of the jack adapter 18 and a through hole 20b of the jack holder 20 corresponding to the coupling hole 18b with fastening means 26. The cable 22 is fixed to a clip 18c of the jack adapter 18 through the hollow part 20a of the jack holder 20 and electrically connected with the jack adapter 18. Here, the clip 18c is fixed by the fastening means 26 when the jack adapter 18 and the jack holder 20 are connected to each other by fastening the connection hole 18b of the jack adapter 18 and the through hole 20b of the jack holder 20 corresponding to the coupling hole 18b with fastening means 26. The reference numerals 16b and 18d designate terminals, 18e designates a press button for pressing the hook 18a, and 19 designates a spring elastically operating the press button.
However, because the phone unit 12 is connected to the body 10 with the adhesive, the conventional mike has a problem that the adhered portion may be detached from the body 10 due to a long-term use or external shock. Furthermore, because the cable 22 is caught to the clip 18c of the jack adapter 18 without any fastening means, the cable 22 may be easily separated from the clip 18c when the cable is pulled from the body 10 due to direct and indirect factors during the use of the mike. Moreover, because the clip 18c is connected to the jack adapter 18 with the fastening means 26, the connected portion may be damaged when the external force is applied. Additionally, because the body 10 and the jack holder 20 are indirectly connected by the hook 18a of the jack adapter 18, the connected state is unstable, and so, the jack holder 20 may be separated from the body 10 due to the external shock.
