Abstract
Description
Technical Field
[0001] The present invention presents a mask of the present invention that improves the reduction of the voice during conversation while the voice during conversation is muffled when using a generally commercially available mask.
Background Art
[0002] Regarding the existing filter configuration of general masks, it aims to purify air containing droplets and inhaled dust in multiple layers, but there is a lack of improvement in the muffling of input voice and attenuation of output voice during necessary conversations when wearing a mask. The mask of the present invention presents an invention that compensates for the drawbacks of existing masks by the system effect of an externally attached hollow voice vibration conduction tube and a small porous speaker, which prevents the diffusion of the input voice during vocalization with a conical cylinder surrounding the mask filter.

Summary of the Invention
Problems to be Solved by the Invention
[0004] This had the following drawbacks. (a) Existing masks focus on filtering pathogenic bacteria droplets and dust, and during face-to-face conversations, the voice is muffled by the filter and the sound pressure is attenuated, making it difficult for both parties in the conversation to hear, causing great inconvenience in social life. (b) To solve these drawbacks of existing masks, the present invention presents a hybrid mask.
Means for Solving the Problems
[0005] The input vocalization from the 3-caliber side of the 2 filters composed of the 1 mask filter material is transmitted to the 4 anti-diffusion induction conical enclosure installed in the filter, and the muffling and volume attenuation of the voice during the use of the existing mask are improved by the 5 externally attached voice vibration conduction tube and the 6 small porous simple speaker.
Effects of the Invention
[0006] (i) The hybrid mask of the present invention compensates for the shortcomings of conventional masks, such as muffled sound and attenuation of generated sound, and is expected to improve communication and social life. (b) The mask function according to the present invention has ventilation holes in items 4, 5, and 6, and filters are used throughout the entire mask, so the risk is low. [Brief explanation of the drawing]
[0007] [Figure 1] This is an elevation and plan view of a mask according to the present invention. [Figure 2] This is a plan view of the upper part. [Figure 3] This is a side view of the mask of the present invention. Embodiments for carrying out the present invention
[0008] According to the present invention, the voice input is introduced into the mask filter from the diameter filter for voice input shown in Figures 2 and 3. A conical, breathable enclosure prevents sound dispersion inside the mask (megaphone effect), and then the sound is transmitted to an external sound vibration conduction tube. A porous miniature speaker prevents muffled sound and attenuation. The mask of the present invention ensures breathability in items 4, 5, and 6, and the filter is utilized from the entire surface of the mask, so the risk is low. [Explanation of Symbols]

Claims
1. This mask invention addresses the drawbacks of masks, such as muffled and attenuated voices during conversations, which make it difficult for the other person to hear clearly.
2. This mask structure filter incorporates a voice input cone enclosure to prevent the sound from diffusing within the mask, and an external voice vibration conduction tube attached to that position transmits the sound to a multi-hole speaker, presenting a system to prevent muffled sound and sound attenuation.
3. This mask includes five audio vibration conduction tubes and six porous speakers, and also proposes the use of four audio input cone enclosure devices as external attachments to existing mask filters to prevent audio input diffusion.
