Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microphone mounting structure for voice input in a voice recognition system.

In general, a voice recognition system analyzes the voice signal from a microphone as a transducer in terms of frequency components, energy components, etc., and then identifies and recognizes the voice by comparing it with signal patterns stored in the system. Yes, a close-talk type microphone is used as the microphone,
In order to faithfully capture the original voice and prevent sound energy from dispersing, the microphone must be located close to the lips and its positional relationship must not change as much as possible during use.

As shown in Fig. 1, the conventional microphone mounting structure has an arch-shaped headband that straddles the head, with support plates 1 at both ends of a headband 1 with a spring action that holds the head.
1 and 11 are connected and held from both sides of the head, and a close-talk type microphone 2, which is held by a holding bar 21 and connected to a cord 22, is fixed to one support plate 11.

However, in this conventional microphone attachment structure, the microphone is held on the head by the spring force of the headband, so the support plates connected to both ends of the headband come into pressure contact with the temporal region, and the pressure force If you make it stronger, the holding will be stable, but it will be limited to a level that does not cause physical pain, so the headband will tend to tilt back and forth around the support plate.
Therefore, there was a problem in that the position of the microphone changed and the audio signal changed, which could lead to malfunction of the system.

The present invention was developed by focusing on the above-mentioned problems.The headband is made into a ring shape that surrounds the head, and the microphone is attached to the headband via an attachment mechanism that allows the position of the microphone to be adjusted. To provide a microphone mounting structure in which a microphone is stably supported.

The present invention will be described below based on embodiments shown in the drawings.

As shown in FIG. 2, the headband 3 has a ring shape, and a belt-shaped body is wound into a ring, buckles 31 and 32 are provided at both ends, and the headband 3 is inserted through the middle part of the corresponding headband 3 while applying sliding resistance. It has a circumferential length adjustment mechanism. The circumference adjustment mechanism may be a hook or button, or an elastic body may be provided in the middle of the headband. The strip is made of resin,
Use appropriate materials such as metal or cloth.

An attachment mechanism 4 for supporting the microphone 5 in an angle-adjustable and distance-adjustable manner is attached to the intermediate portion of the single ring between the buckles 31 and 32, and the microphone 5 is supported.

The mounting mechanism 4 includes a base 43 having a support fitting 42 attached to its tip via an arm 41 fixed to the headband 3 and extending in the radial direction, and a support fitting 42.
A mounting bar 46 is inserted into an insertion hole 44 formed in a substantially vertical direction and can be adjusted vertically with a set screw 45.
is supported, and a tightening screw 4 is attached to the lower end of the mounting bar 46.
A joint portion 7 is provided with a ball gripping portion 48 whose gripping force can be adjusted, and the ball gripping portion 48 grips a ball 49 connected to a support base 52 that supports the microphone 5 via a support arm 51. It consists of 50. Microphone 5 has code 5
3 is connected to the voice recognition system.

To adjust the position of the microphone 5, move the buckles 31 and 32 of the headband 3 to match the circumference of the head, and then put it on the head. Next, the set screw 45,
By loosening the tightening screws 47 as appropriate and sliding the mounting bar 46 in the vertical direction, or by moving the support base 52 of the microphone 5, the ball 4 can be attached.
Once the microphone 5 is adjusted to an appropriate position near the lips, each part is fixed using the set screw 45 or the tightening screw 47.

Note that the attachment mechanism may be a universal joint or the like instead of a ball joint, as long as it can be adjusted in angle and distance.

According to the microphone attachment structure according to the present invention, since the headband is shaped like a ring surrounding the head, it can be stably attached to the head, and the load applied to the head is also dispersed, causing less physical pain. Since the microphone is attached to the headband so that its angle and position can be adjusted using the attachment mechanism, the microphone can be adjusted to an appropriate position, and the voice signal to the voice recognition system is stable and does not malfunction.
