Description

[0001] Microphone device with a speaker [0002]

[0001] The present invention relates to a microphone device having a speaker, and more particularly, to a microphone device and a speaker unit which are separated from each other and have a sound output portion surrounding a lower side of a speaker portion, The present invention relates to a microphone device having a speaker capable of blocking a howling generating element and capable of transmitting sound evenly in any direction around a microphone user.

Generally, a lecture or a meeting is performed through a wireless microphone system in a small space such as a lecture room or a company meeting room of a school / institute. In such a wireless microphone system, a speaker device receives an audio signal transmitted from a microphone and converts it into an acoustic signal This system has the effect of eliminating the inconvenience of place movement restriction that occurs when using a conventional wired microphone, and is conventionally used.

In such a wireless microphone system, the audio signal transmitted from a microphone installed in one classroom or a conference room is received by a wireless speaker installed in the same class room, and a sound is output. Since the microphone, the speaker, and the amplifier are separately installed, There is a problem that it is not only complex but also troublesome in operation.

In order to solve the above problems, a 'karaoke microphone toy having a built-in speaker' in which a microphone and a speaker are integrally formed is disclosed in a registered utility model No. 20-0382291 (hereinafter referred to as a 'registration utility model').

The registrant utility model comprises a head portion 10a and a handle portion 10b in the shape of a conventional microphone and has a groove 11 at the center of the head portion 10a and a battery accommodating portion A microphone 10 mounted on the recess 11 and a microphone 10 mounted on the inner side of the handle 10b at a position corresponding to the sounding hole 13, A control unit 41 and an accompaniment tune storage unit 42 are provided to amplify a voice signal input from the microphone device 20 and output the amplified voice signal to the accompaniment tune storage unit 42 A circuit board 50 provided with a microcomputer 40 for outputting the selected accompaniment tune to the speaker 30 together with the selected accompaniment tune and inserted into the handle 10b, And an upper end portion of the power source is installed to protrude to the outside of the handle portion 10b Is characterized by comprising a tooth 60 and the music selection switch 70.

However, the registration utility model is configured such that a voice signal input from the microphone device 20 is outputted to the outside through the sound hole 13 formed at the lower end of the handle 10b via the speaker 30, Since the structure in which the head portion 10a on which the speaker 30 is mounted and the handle portion 10b on which the speaker 30 is mounted are in communication with each other, there is no structure for solving the howling, 13, it is impossible to spread the voice signal widely and can not be used for lecture or conference.

[

On the inside of the microphone unit 100, power control of the microphone unit according to the operation of the button unit 112, blinking control of the power display unit 113, and control of blinking of the audio signal from the microphone unit 120 to the main speaker 210 And a control board 130 for controlling transmission of the voice signal to the control board 130. The control board 130 is preferably provided with a small output amplifier 140 for amplifying voice signals.

The speaker unit 200 is coupled to a lower portion of the microphone unit 100 and outputs a user's voice signal. The speaker unit 200 includes a main speaker 210, a speaker body 220, and a reflection plate 230.

The main speaker 210 is connected to the microphone device 120 through the control board 130 and outputs a voice signal input through the microphone device 120. The main speaker 210 may be a small speaker such as a lecture room or a conference room, And a speaker usable with the amplifier 140.

The main speaker 210 is fixed to the inside of the speaker body 220 by fixing protrusions 222 of a speaker body 220 to be described later. In the present invention, The speaker 230 is fixed to the reflector 230 so that the user's voice signal output through the speaker 210 can be radially spread by the reflector 230. [

The speaker body 220 is coupled to a lower portion of the microphone unit 100 to form a space in which the main speaker 210 is installed. The main speaker 210 is formed of a closed space separated from the main speaker 210 to form a resonating space S of the main speaker 210.

Generally, a pitch band to be reproduced by each speaker is determined. In the case of the main speaker 210 of the present invention, a structure for reinforcing the pitch band is needed because it is a small structure that can be used in a small space. The sounding space S is provided on the inner side of the speaker body 220 of the present invention so that it is possible to reinforce the voice band by complementing the backside vibration of the main speaker 210.

1, the sound output unit 221 may include a sound output unit 221 and a sound output unit 220. The sound output unit 221 may include a speaker unit 220, As shown in FIG. 2, it is also possible that a plurality of sound output portions 221 spaced apart from each other at a predetermined interval are formed to surround the bottom of the side surface.

The voice output unit 221 is formed to surround the lower side of the speaker body 220 so that the voice signal reflected by the reflection plate 230 can be radially spread out, An efficient voice transmission of a user using a microphone device is performed.

Meanwhile, a fixing protrusion 222 protruding from the inner circumferential surface of the speaker body 220 for fixing the main speaker 210 is provided inside the speaker body 220.

The reflector 230 reflects a voice signal output through the main speaker 210 positioned at the lower end of the speaker body 220. In the present invention, the reflector 230 reflects a user of the microphone device And is characterized in that the voice signal is reflected so that voice transmission is performed well in either direction.

The reflection plate 230 is configured to form a downward sloping surface in the outward direction from the central portion so that the voice signal output through the main speaker 210 can be radially spread out around the user of the microphone device, And 4, it may be conical or hemispherical.

The reflection plate 230 has a downward slope structure to block the output signal of the main speaker 210 from moving to the microphone element 120, thereby blocking the howling generating element.

Although the reflection plate 230 is shown in the form of a cone or a hemisphere in the drawing of the present invention, the reflection plate 230 may have various structures that can spread radially evenly around the user of the microphone device.

6, the speaker unit 200 may further include an auxiliary speaker 240 installed inside the resonance space S of the speaker body 220 to reinforce the low frequency band. And the auxiliary speaker 240 is fixed to the inside of the speaker body 220 by fixing means.

Hereinafter, a process of outputting a voice signal through the speaker unit 200 of the microphone device having the speaker according to the preferred embodiment of the present invention will be described with reference to FIG. 5, when a user's voice signal is output through the main speaker 210, an output signal is reflected by the reflection plate 230. The reflection plate 230 has a conical or hemispherical shape, The structure of the speaker and the structure of the voice output unit 221 formed around the lower side of the speaker body 220 allows the user's voice signal to spread radially around the user of the microphone device, So that efficient voice transmission of the user to be used can be achieved.
