BACKGROUND OF THE INVENTION
The present invention relates to a microphone, and more particularly, to a microphone that is separated into a base portion and a head portion and electrically connected in a state where the microphone is located on the front and back of the clothes and fixed to the clothes.
[0002]
[Prior art]
Conventionally, in broadcasting studios and the like, as shown in FIG. 4, a small microphone 110 with a case attached to an ultra-small condenser microphone unit is attached to clothes and used for collecting news and dramas. In the microphone 110, the audio signal output cable C is extended from the lower part of the main body.
[0003]
In this microphone 110, since the output cable C may be conspicuous outside the clothes, the microphone 120 is separated into a head 121 and a base 122 as shown in FIG. By inserting contact pins 123 and 124 penetrating (shown in FIG. 6) into pin receivers 125 and 126 formed on the base 122, the head 121 and the base 122 are electrically connected, and the garment W is attached to the clothes W. It is possible to devise so that it can be fixed.
[0004]
In the microphone 120, as shown in FIG. 6, only the head 121 can be put on the outside of the garment W, and the base 122 and the output cable C can be inside the garment W.
[0005]
The microphones 110 and 120 are used by connecting the output cable C to a transmitter of a wireless microphone or by connecting to an input of a microphone amplifier by wire.
[0006]
[Problems to be solved by the invention]
However, in such a conventional separate type microphone 120, since the head 121 and the base 122 are connected by the two contact pins 123 and 124 penetrated through the clothes W, the clothes W can be stably provided. There is a difficulty in maintaining the state of being attached to the connector, and there is a possibility that the contact pin 123 is inserted into the pin receiver 126 and the contact pin 124 is inverted into the pin receiver 125 and inserted. Furthermore, in order to simplify the structure, since the audio output signal is taken out from the drain side of the FET built in the head 121 with high impedance, there is a problem that it is easy to pick up ambient noise.
[0007]
The present invention has been made to solve such problems, and provides a superior microphone that can be stably fixed to clothes and is not affected by ambient noise in a separation-type microphone. is there.
[0008]
[Means for Solving the Problems]
The microphone of the present invention is a microphone in which a microphone base portion and a microphone head portion are coupled to each other by a pin penetrating clothes and fixed to the clothes, and the microphone base portion and the microphone head portion are electrically connected by the pins. The three pins are erected on one of the microphone base portion or the microphone head portion, and the three pins are inserted into the other of the microphone base portion or the microphone head portion, respectively. Three pin receivers are connected to each other, and three of the pins are contacts for supplying power from the microphone base to the microphone head, ground contacts for the microphone head and the microphone base, Or a contact for outputting an audio signal from the microphone head unit to the microphone base unit. It is characterized in.
[0009]
With this configuration, the microphone base part and the microphone head part can be fixed to the clothes and electrically connected by inserting the three pins through the clothes and inserting them into the pin receiver. Each of the three pins can constitute a power supply contact, a ground contact, or an audio signal output contact. Therefore, even with a small divided microphone, the impedance of the audio signal output can be kept low, making it less susceptible to external induced noise and so on, and not being affected by ambient noise. it can.
[0010]
Here, since the pin is a set of three pins, it can be prevented from being inserted into an erroneous pin receiver only by being arranged at a non-rotationally symmetrical position other than being arranged in a straight line at equal intervals. And a lock mechanism that locks at least one of the pins so as not to be removed from the pin receiver so that the pin is not accidentally dropped. The lock mechanism includes an elastic member and the elastic member. It is preferable to have an elliptical rotating shaft biased in the pin receiving direction by a member and a lever that rotates the rotating shaft integrally with the rotating shaft .
[0011]
Furthermore, by changing the length of one or two of the pins with the length of the other pins, it is possible to penetrate the garment with less resistance than when penetrating the garment three at the same time, and it is easy to align. Become.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. 1 to 3 are diagrams showing an embodiment of a microphone according to the present invention.
[0013]
In FIG. 1, the microphone 10 is configured to be small in size so that a microphone head portion 11 located outside the clothing W (shown in FIG. 2) and a microphone base portion 31 located inside the clothing W are assembled and used. The microphone head unit 11 receives sound from an announcer or the like that collects sound from the sound hole 12 that is opened to a large size and stretched with a net, as shown in FIG. 2 and FIG. The microphone base unit 31 receives the audio signal from the microphone head unit 11 and outputs it to the output cable C while picking it up and converting it into a signal. The microphone 10 employs a wired form that outputs an audio signal to the output cable C, but it goes without saying that it may be configured wirelessly.
[0014]
In the microphone 10, contact pins 36 to 38 that allow the clothes W to pass through are erected on the microphone base portion 31, while pin receivers 16 to 18 into which the contact pins 36 to 38 are inserted are formed on the microphone head portion 11. For example, as shown in FIG. 2, the contact pins 36 to 38 are formed longer than the other contact pins 36 and 37 (37 is not shown) so that the contact pins 38 to 38 have different lengths. Is designed to penetrate the garment W quickly. Therefore, the contact pins 36 to 38 can be sequentially penetrated from the contact pin 38 to the contact pins 36 and 37 without resistance as compared with the case where the clothes W are simultaneously penetrated, and the microphone 10 can be easily aligned. . Needless to say, the lengths of the contact pins 36 and 37 may be changed.
[0015]
Further, as shown in FIG. 2, the contact pins 36 to 38 and the pin receivers 16 to 18 are formed by the contact pins 36 and 37 inserted through the clothes W as a pair of connection pieces 16a of the pin receivers 16 and 17, respectively. , 17a (17a is not shown) is inserted and mechanically connected and held, while the contact pin 38 is pressed and connected to the connection piece 18a of the pin receiver 18 by a lock mechanism described later, Each is electrically connected. Therefore, only by inserting the contact pins 36 to 38 into the pin receivers 16 to 18, the microphone head unit 11 and the microphone base unit 31 are connected in an electrically connected state, and the audio signal from the microphone head unit 11 is transmitted to the microphone. It can be output to the output cable C via the base portion 31, and the microphone head portion 11 and the microphone base portion 31 are connected to the clothes W by connecting the three pairs of contact pins 36 to 38 and the pin receivers 16 to 18. It can fix more firmly than the case of two sets.
[0016]
The microphone head part 11 and the microphone base part 31 are provided so that the contact pins 36 to 38 and the pin receivers 16 to 18 are positioned at the apexes of the triangle (formed in a non-rotationally symmetrical manner) and correspond one-to-one. The microphone head unit 11 can be connected only by a combination, and the microphone head unit 11 is connected to each of the contacts formed by the contact pins 36 to 38 and the pin receivers 16 to 18 via the microphone base unit 31 (output cable C). A contact for supplying power to the FET 14, a contact for grounding the microphone head 11 and the microphone base 31, and a contact for outputting an audio signal from the FET 14 of the microphone head 11 to the microphone base 31 can be configured. . Therefore, in the state where one of the microphone head part 11 or the microphone base part 31 is relatively rotated, it is impossible to insert the contact pins 36 to 38 into the pin receivers 16 to 18 to prevent a connection error in advance. In addition, by outputting an audio signal with a low impedance from the source side of the FET 14 in the microphone head section 11, it is possible to increase resistance to external induced noise.
[0017]
And the microphone head part 11 is arrange | positioned with the lever 21 by which the one end side was supported by the rotating shaft 21a so that it might rotate integrally with the rotating shaft 21a provided in the side surface of the exterior cover, As shown in FIG. 2, the rotating shaft 21a of the lever 21 is integrally formed with an elliptical rotating shaft 23 biased in the direction of the connecting piece 18a of the pin receiver 18 by an elastic member 22 such as a spring or a spring. To be coaxially rotated. For this reason, when the lever 21 is rotated from the position indicated by the broken line in FIG. 1 to the position indicated by the solid line, the elliptical rotating shaft 23 causes the connecting piece 18a of the pin receiver 18 to move to the longer diameter side as shown in FIG. The connection piece 18a can be pressed against the contact pin 38 and mechanically strongly joined and locked so as not to come off during use. That is, the lever 21 and the rotating shaft 23 constitute a lock mechanism. In addition, the rib 24 in FIG. 2 is erected on the opposite side of the rotating shaft 23, and restricts the connection piece 18 a of the pin receiver 18 pushed by the rotating shaft 23 from escaping.
[0018]
As described above, in this embodiment, the microphone head portion 11 and the microphone base portion 31 have the wrong connection positions due to the contact pins 36 to 38 and the pin receivers 16 to 18 that are arranged so as to be located at the apexes of the triangle. It can be firmly fixed to the clothes W and electrically connected, and by securing each of the power supply contact, the ground contact, and the audio signal output contact, the impedance of the audio signal output is kept low. It can be made less susceptible to external induced noise. In addition, the connection piece 18 a of the pin receiver 18 can be locked by tightening the contact pin 38 by the locking mechanism of the lever 21 and the rotating shaft 23. Therefore, even the small microphone 10 that is assembled by separating the microphone head portion 11 and the microphone base portion 31 is attached to the clothes W so as not to be inadvertently dropped, and is influenced by ambient noise. You can pick up the voice of the announcer and so on.
[0019]
【The invention's effect】
As described above, the present invention allows the three pins to pass through the garment and connect the microphone base part and the mic head part, so that it can be fixed to the garment and electrically connected, The three of these pins constitute the power supply contact, the ground contact, and the audio signal output contact, respectively, so that the impedance of the audio signal output can be kept low and is not affected by ambient noise. A microphone having an effect can be provided.
[0020]
In addition, it is possible to provide a microphone that prevents erroneous connection by arranging the three pins at non-rotationally symmetric positions.
