Description
The divisional application is based on the divisional application of Chinese patent application with the application number of 201710613788.7, the application date of 2017, 7 and 25, and the name of the invention of 'a breathable mask for transmitting sound'.
Technical Field
The invention relates to a breathable mask for transmitting sound, which can clearly transmit sound without taking off the mask.
Background
The gauze mask can block that harmful substance gets into the human body through breathing in the air, and along with the industrialization increases, air pollution is serious day by day, especially haze problem, and the population of wearing the gauze mask is also more and more, and during the influenza, most people wear the gauze mask at any time more, avoid the disease infection.
Although the mask can block harmful substances such as dust, bacteria, viruses, chemical aerosol, pollen and the like in the air, the mask body is made of porous fabric for air to enter and exit, and sound can be absorbed by the pore structure of the mask, so that the speaking sound of the mask worn by the user is small, distorted and unclear.
In recent years, the opportunity of answering the call while wearing the mask is increased because a user holds one mobile phone, but a lot of people can choose to take off the mask to answer the call because of the sound absorption problem of the mask when talking about important things, and thus the protection function of the mask is lost.
Therefore, how to design a mask capable of clearly transmitting sound is a mask function which is very needed by modern people when the mask is worn.
Taiwan patent M536070 is a mask with a sound transmission structure, and can transmit sound to the outside of the mask without taking down the mask during speaking, and the mask comprises a mask body and a sound transmission structure, and holes are arranged on the mask body, and the sound transmission structure comprises a sound film, and the sound transmission holes in the mask and the sound transmission structure clearly communicate the outside of the mask. Although the sound film is used to transmit the sound in the mask in the prior art, the probability of sealing the opening is poor, which results in failure of the protection function of the mask and influences the transmission of the sound.
Therefore, how to design a mask capable of clearly transmitting sound without adding extra material to increase the cost of the mask is an important subject to be solved by the present invention.
From the foregoing, there is a need for a novel method to assist a user in properly solving existing problems.

The using effect of the mask is as follows: wearing gauze mask test sound transmission effect, holding the cell-phone when wearing gauze mask and speaking, seeing through the cell-phone can hear user's clear, clear sound, can know that gauze mask seals pressure department and does not have the pore to absorb sound, therefore sound can effectively transmit, seals in addition and presses the department and present appointed colour, can do benefit to and distinguish different usage, user's gauze mask or let the gauze mask more pleasing to the eye.
EXAMPLE 3 Sound-transmitting breathable mouth piece of three-layer construction
As shown in fig. 1, a three-layer breathable mask 1 is taken, a breathable mask body 10 is made of Polyethylene (PE) fiber non-woven fabric, sealing and pressing are performed by an ultrasonic sealing machine at a position (left side in the figure, namely, a side close to the right hand when the mask is used) below the breathable mask, the sealed and pressed position is subjected to sealing and pressing hot melting so that pores of the PE fiber are mutually dissolved and bonded at high temperature to form a sound transmission structure 11, the sound transmission structure (11) can be a square shape with the length and width of 0.5 cm-2 cm, the cross section of the mask is shown in fig. 2, the three layers of the mask inner layer 101, the mask middle layer 102 and the mask outer layer 103 are bonded at the sound transmission structure 11 through sealing and hot melting, the sealed and pressed position can be selected to be transparent, but the color of the sealed and pressed position is not limited to be transparent; the mask material may be replaced by other artificial fibers such as PU (polyurethane), PP (Polypropylene), PE (Polyethylene), PET (Polyethylene terephthalate), PB (polybutylene), or Polystyrene (PS) in addition to PP.
The using effect of the mask is as follows: the mask is worn to test the sound transmission effect, the right hand is used for holding the mobile phone to talk, the clear and clear sound of the user can be heard through the mobile phone, and if the left hand is used for holding the mobile phone, the sound is clear and clear. Through the test, it can be known that no pore is arranged at the sealing position of the mask to absorb the sound, so the sound can be effectively transmitted.
Example 4 Sound-transmitting vented hood with Sound-amplifying function
Referring to fig. 3, a three-layer ventilation mask 1 is taken, a ventilation mask body 10 is made of a PET fiber non-woven fabric, an ultrasonic sealing machine is used for sealing and pressing the lower part of the ventilation mask on the right side, the sealed and pressed part 11 is subjected to sealing, pressing and hot melting to enable pores of the PET fiber to be mutually dissolved and bonded due to high temperature, the sealed and pressed part is a circular structure 11 with the diameter of 0.5 cm-2 cm and forms a sound transmission structure 11, the sound transmission structure and a circular structure outside the circular structure form a folding ring 12, and the diameter or the length and the width of the folding ring are 0.6 cm-3 cm. The section of the mask is as shown in fig. 4, the mask inner layer 101, the mask middle layer 102 and the mask outer layer 103 are bonded by hot melting at the sound transmission structure 11 and the folding ring 12 due to sealing pressure, and have no pores, the sealing pressure part can be selected to be transparent, but the color of the sealing pressure part is not limited to be transparent; the mask material may be replaced by other artificial fibers such as PU (polyurethane), PE (Polyethylene), PP (Polypropylene), PB (polybutylene) or Polystyrene (PS) in addition to PET.
The using effect of the mask is as follows: wearing the gauze mask and testing the sound transmission effect to the right hand is held the cell-phone and is spoken, sees through the cell-phone and can hear user's loud, clear sound, and on the left side of no sound film, the volume diminishes, has the condition of sound distortion simultaneously. Through the test, it can be known that there is no pore to absorb sound at the sealing position of the mask, so that the sound can be effectively transmitted, and the folding ring at the periphery of the sound transmission structure increases the power and elasticity of the longitudinal wave of the middle sound transmission structure, thereby having the effect of expanding the sound.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
