Description

Wired earphone, wireless earphone, true wireless earphone, mask earphone and mobile phone
Technical Field
The invention particularly relates to a wired mobile phone earphone, a wireless mobile phone earphone, a true wireless mobile phone earphone, a mask mobile phone earphone and a mobile phone, and belongs to the technical field of mobile phones and accessories thereof.
Background
The mobile phone is a communication tool frequently used in daily life.
The earphone of mobile phone is an electronic accessory for people to make and receive calls, listen to music, play games and use digital audio players, portable electronic games, walkman and radio, etc.
Technically, a mobile phone earphone is an acoustic-electric interchanging device which converts an electric signal emitted by a mobile phone or a media player and the like into a sound wave of a loudspeaker close to an ear and transmits the sound wave to the ear of a person or converts a sound wave of the person into a radio wave capable of being transmitted wirelessly. Typically including a speaker, a microphone, a signal processing circuit, a communication (link) device, etc. The number of parts sold for mobile phone earphones is reported to be hundreds of millions worldwide every year, and the market prospect is huge. (e.g., new changes are introduced to the headset industry, TWS headsets or there is still hundreds of billions of dollars of growth space),http://www.soomal.com/doc/10100008760.htm) (ii) a According to data display of a Counterpoint of a market research mechanism, the wireless earphones are increased explosively, in 2017, 2018 and 2019, the shipment rate of the wireless earphones is increased to 118%, 130% and 183%, and the wireless earphones are in a rapid development state. The market scale of the global wireless earphones in 2019 exceeds 1.2 hundred million. Under the influence of epidemic situations, although the worldwide wireless headset market is rapidly revived after the first quarter in 2020, the second quarter shipment has increased by 18% and has become the main driving force for the increase in the 2020 headset market. "
https://weibo.com/ttarticle/p/showid=2309404578796635553914;"one pair of small earphones, hidden behind them in billions of markets. In 2019, since the next half year, the real wireless earphone with the TWS technology as the core enables the 'heat' of the intelligent wearable equipment which is 'cool' for a period of time to rise. Becoming one of the A stock market hotspots in 2019, the TWS earphone concept that the stock price is red all the way, even being labeled with 'annual stable earning'. Wherein, the stock price of the strollers rises by 300 percent within 60 days, and each stock rises from 5.67 yuan to 30 yuan within half a year; the core concept of Ying Tong communication, co-arrival electroacoustic and Yiwei Li energy wireless earphone panels also explodes intensively and rises successively. In fact, since the first generation of airpots released by apple 2016, pioneering the real wireless earphone age, players who come into the market at different times, including traditional audio manufacturers and mobile phone manufacturers, have been in a state of hundreds of buzzes, and white cards and brand wildness have been growing for three years. "http://epaper.oeeee.com/epaper/A/html/2020-01/ 23/content_3926.htm(ii) a "the brand is various and complicated in the present market", "the wireless earphone market is a bouquet of war"http://news.hexun.com/2020-02-18/200333602.html. And so on. (accessed via link 20210316 above.)
However, the current problem of the existing mobile phone/earphone is — -
(scene one) (1) when people read books and learn in a library, people usually want to be quiet (quiet) suddenly and make a phone burst, namely people do not answer the phone and worry about accidents, and the answering of the phone affects other people, namely people with small voice cannot hear the other party, and people with loud voice (who are in the neighborhood are disturbed) or even library managers stop the phone in time; (2) some people use the earphone, but the earphone also has the problems that loud speaking affects the quiet environment of the library, workers stop or feel people around the earphone, the opposite party of the small speaking telephone cannot hear the earphone, and delay is not needed.
In the second scenario, people do not want to speak loudly to the mobile phone to let others hear (protect privacy) in the office when working, or do not want to influence others (interfere others) (influence others), and people want to speak loudly, but speak loudly and the other party of the mobile phone may not hear.
In the third scenario, or on the subway, some private matters of the user do not want to hear the advertisement, and meanwhile, the user does not answer the phone and worrys about the wrong affairs, the phone affects other people, the other party with small voice cannot hear the person, and the louder person is refused or even prevented by people around the user. "quiet chat" (in light words) is a "desire" for some people, however, the prior art is unavailable (difficult) (the whisper is not audible), … ….
(scene four) or in life, take-away, courier and the like speak normally, and due to wind sound and other reasons, the other party who answers the call can not hear the voice normally (the other party who makes the call can not hear the voice normally); … …, etc.
(scene five) or normal speaking, some old people are low in voice and cannot hear due to hearing, and want to speak loudly ("roar", which is not happy, … …).
When taking a bike, the take-out and express delivery personnel can not hear clearly the person (both parties) who receives the call from the opposite party due to wind noise, the take-out and express delivery personnel stop receiving the call and delay the work, and the taking a call while riding the bike is not safe and sometimes cannot hear the call.
That is, when a light voice is required (in the environment) (and in privacy) in a library, at work, on a subway, or the like, the user cannot hear the talking with a small voice. This is a problem that people often encounter; alternatively, normal speech such as cycling wind problems, hearing problems, etc. may not be audible.
The improvement of the prior art mobile phone or headset is mostly an improvement in noise reduction technology, i.e. how to select the desired sound from a large amount of noise. The present invention has the following difficulties: (here) how whisper is speaking without noise (very quiet library), and how whisper is speaking normally (other, or privacy concerns are taken), i.e. what needs to be solved is (quiet environment or privacy is not wanted to hear), how whisper is speaking, and how whisper is normal or loud speech (audio) available to the opposite party of the handset?
With respect to the definitions of "soft", "soft" and "soft", herein, some (approximate) description of the relationship of sound to decibels is provided on the internet for reference only. For example, table one: sound versus decibel description.
Table one: description of sound versus decibels
Item(s) Decibel value Sound equipment Item(s) Decibel value Sound equipment
1 1 A just audible sound; 2 10 in a very quiet room, the leaves are rastered by wind;
3 15 feeling quiet; 4 30 the volume of whisper; ticks for quiet clocks and watches;
5 40 the hum of the refrigerator; 6 50 working sound of washing machine
7 60 Sound of normal conversation 8 70 Equivalent to walking in downtown area
9 85 On the road that the car shuttles back and forth 10 95 Motorcycle starting sound
11 100 Sound of decoration electric drill 12 110 Karaoke OK, loud playing MP3 sound
13 120 Sounds when aircraft take off 14 150 Sound for setting off fireworks and crackers
Here, we define: sounds that are lower than normal conversations (60 db) can be considered "soft", "small", "low".
It should be noted that "soft sound", "soft sound" and "soft sound" (which may be defined by decibels) or may be described (defined) by the approximate perception of a human being. (one may but need not necessarily be defined in terms of decibels). People can decide whether to be 'soft sound', 'low sound' or 'low sound' according to needs (according to own feelings). (here, a sound lower than a normal conversation (60 db) is considered to be "soft sound", "soft sound". The meaning of "soft sound", "soft sound" is probably the same, and is lower than that of a normal speech sound.) that is, the meaning of "soft sound", "soft sound" and "soft sound" in the present invention is clear. (i.e. lower than 60 decibels)
The existing mobile phone earphones can be generally divided into the following types according to wired and wireless technologies: wired cell phone headset, wireless cell phone headset, true wireless cell phone headset etc.: (here is "wired cell phone earphone, wireless cell phone earphone", and does not direct and simply "wired earphone, wireless earphone", mainly because there are some wired earphone(s), wireless earphone mainly listens song (Hi-Fi), there is not microphone, but (improvement) of the invention mainly involves the microphone (microphone Mic, receiver), the invention is for showing difference, accurate, here the text stresses "wired cell phone earphone, wireless cell phone earphone". for simplicity, hereinafter, some "wired earphone" refers to "wired cell phone earphone", "wireless earphone" refers to "wireless cell phone earphone", "true wireless earphone" is "true wireless cell phone earphone"; … …. the same

The other parties are similar to the operation and complete the two-party conversation with each other. There are many types of existing wired headphones, for example, brand: apple, model: earpos (3.5 mm round-head interface) wired handset, brand: hua is, type: AM116 wired headset, brand: OPPO, type: MH135 wired headphones, brand: walker, type: h180plus wire-controlled headphones, and so on.
(II) wireless earphone
The traditional wireless earphone usually has the functions of removing a data line and a plug of a wired earphone, connecting (communicating) with a mobile phone through wireless transceiving technologies (devices) such as Bluetooth and the like, and connecting a main loudspeaker and an auxiliary loudspeaker through wires. Fig. 3 is a schematic diagram of a conventional wireless headset circuit structure. In the figure, 5-main speaker, 6-auxiliary speaker, 7-microphone (mic), 8-volume control switch, 9-signal processing circuit, 12-bluetooth (or other wireless transceiving technology) transceiver, 14-charging interface, 15-battery, as shown in fig. 3, a general wireless headset includes a main speaker 5, an auxiliary speaker 6, a microphone (mic)7, a volume control switch 8, a signal processing circuit 9, a bluetooth (or other wireless transceiving technology) transceiver 12, a charging interface 14, a battery 15, etc., the main speaker 5, the microphone (mic)7, the volume control switch 8, the signal processing circuit 9, and the bluetooth transceiver 12 are electrically connected, and the bluetooth transceiver 12 is paired with a mobile phone, wirelessly connected and cooperatively used; the battery supplies power to the circuit (the battery is charged through the charging interface in a wired mode or in a wireless mode; the main loudspeaker 5 and the auxiliary loudspeaker 6 are connected by wire; the main loudspeaker 5 and the auxiliary loudspeaker 6 are used for listening to human ears. There are also a number of existing wireless headset varieties, for example, brand: three stars, type: galaxy BUDS Pro bluetooth headset, brand: memory sail, model: an ear-hung IPX7 wireless headset; brand name: free, type: k21 wireless bluetooth headset, brand: MAVE, model: x9 ear-hang headphones, etc.
(III) true wireless earphone
True Wireless headsets, the acronym for "True Wireless Stereo" in english. (true wireless earphone generally contains left speaker, right speaker, and left and right speaker separately independent, wireless, left and right speaker contain microphone (mic) respectively, volume control switch, signal processing circuit, bluetooth transceiver, battery, the interface that charges etc. (left and right speaker and their own microphone (mic), volume control switch, signal processing circuit, bluetooth transceiver, battery, charging interface circuit link.) figure 4 is a current true wireless earphone structure sketch map. Fig. 4(a) is a schematic structural diagram of a conventional wireless headset (a pair), and fig. 4(b) is a schematic structural diagram of a conventional wireless headset storage (charging) device. Fig. 5 is a schematic diagram of a circuit structure of a conventional true wireless earphone (one of the ears). In the figure, 5-loudspeaker, 7-microphone (mic), 8-volume control switch, 9-signal processing circuit, 12-bluetooth transceiver, 14-charging interface, 15-battery (power supply), as shown in fig. 4 and 5, the real wireless earphone generally comprises a main loudspeaker and a sub-loudspeaker, which are separated and wireless, the main loudspeaker and the sub-loudspeaker respectively comprise microphone (mic)7, volume control switch 8, signal processing circuit 9, bluetooth transceiver 12, battery 15, charging interface 14, etc., the main/sub-loudspeaker is connected with the microphone (mic), volume control switch, signal processing circuit, bluetooth transceiver, battery, charging interface circuit, etc., which the real wireless earphone of the latest technology can be left and right (main loudspeaker, right loudspeaker, bluetooth transceiver, battery, charging interface circuit) Auxiliary) loudspeaker and its bluetooth transceiver can all use simultaneously, alone etc., microphone (mic)7 is used, communicated through the pairing of volume control switch 8, signal processing circuit 9, bluetooth transceiver 12 and cell-phone. Some important differences between the current true wireless headset and the wireless headset are: (1) the wireless earphone main loudspeaker 5 and the auxiliary loudspeaker 6 are connected through wires; the left loudspeaker and the right loudspeaker of the true wireless earphone are not connected in a wired way; the left loudspeaker 5 and the right loudspeaker 6 of the real wireless earphone line are wirelessly connected and then wirelessly connected with the mobile phone; or, each is connected with the mobile phone in a wireless way and used independently. (2) The left and right loudspeakers of the real wireless earphone line respectively (self) comprise a microphone (mic)7, a volume control switch 8, a signal processing circuit 9, a Bluetooth transceiver 12, a battery 15, a charging interface 14 and the like.
(1) Currently, the first common wireless headset of the true wireless headset is a bluetooth chip, the mobile phone and the headset perform 1-to-1 audio transmission, and the communication between the mobile phone and the True Wireless (TWS) headset needs to realize 1-to-2 audio transmission, but the bluetooth protocol is 1:1 connection, that is, for the earlier bluetooth protocol, the mobile phone can only transmit audio to one headset, but how can the other headset hear sound? One method is to connect the right earphone with the mobile phone, and tell the left earphone when the pairing password is stolen, and the left earphone can monitor the bluetooth signal after the password is provided. The monitoring mode monitors signals sent by the mobile phone according to a certain rule, and finds out respective signals of the main ear or the auxiliary ear from the received signals for respective use, so that good experience is obtained. For example, apple airpots are true wireless headsets using listening technology.
(2) Currently, the second true wireless earphone android system adopts a forwarding scheme in true wireless earphone schemes of a plurality of earphone companies. Adopting a forwarding scheme: i.e. the right earpiece receives the signal first and then forwards the sound to the left earpiece. Compared with the listening mode, the forwarding scheme has the following disadvantages: (a) the right earphone needs to receive signals and transmit the signals, so that power consumption is greatly improved; endurance has a great problem. (b) The connection is not particularly stable due to the process of requiring the right earphone to be forwarded to the left earphone, with the middle having a brain sack. (c) The reason for the greatest effect, delay! Because the signal reaches the right earphone first and then the left ear, the sound of one earphone is necessarily slower than the audio of the mobile phone. The audio and video will not be synchronized.
(3) In 2018, in the third real wireless technology, the TWS + (TrueWireless Stereo Plus) technology is introduced by the university company, and the two links are provided, so that the left channel is transmitted to the left ear, and the right channel is transmitted to the right ear, which breaks through the existing bluetooth technology. The high-pass QCC5100series platform is said to support TWS + characteristics, and the new TWS Erphone of VIVO adopts the series QCC5126 chips.
(4) At present, the fourth true wireless technology is also applied by hengxian company as LBRT-low frequency forwarding technology: the mobile phone transmits 2.4G Bluetooth signals to the main earphone, and then forwards the signals to the auxiliary earphone at a frequency band of 10-15MHZ by a magnetic induction forwarding technology. Thus, the penetration of signal is enhanced, and the loss of tone quality is avoided, and the delay is reduced. Namely, it is necessary to add a low frequency antenna to the earphone. The Henchang BES2300 product supports the LBRT property, which was adopted by Huacheng Freemuds 2.
(5) At present, the fifth true wireless technology is also called MCSync, where a network access company adopts a synchronous receiving mode, and after the set-up is completed, each earphone has a signal to connect, which is called by the official: the connection is more stable, the sound break and the sound jump are reduced, high-resolution audio code streams are supported, the time delay is low, the power consumption of two ears is more balanced, and the mobile phone is suitable for various mobile phone platforms. The A1532/A1536/A1552x of netda supports the MCSync characteristic. Wherein A1536 is the main scheme of high-imitation products of Airpods, and A1552x is the scheme quotient of WF1000XM3 of the new generation of noise-reduction beans of Sony.
(6) The Bluetooth 6.0 directly supports the TWS from the protocol architecture, except that various major manufacturers research, develop, optimize and promote on the forwarding technology, the Bluetooth 6.0 protocol formulated by the Bluetooth SIG association may directly support the TWS characteristics from the protocol architecture, and some proposals (algorithms) may be quickly incorporated, which is expected.
At present, a wired connection mode is abandoned outside a real wireless Bluetooth headset, the problem of winding of a headset wire is avoided, and great convenience can be realized; due to the characteristic that the left and right units of the TWS headset are not physically connected, the Bluetooth headset is not charged through a micro USB interface in general. In order to solve the problem, the real wireless Bluetooth headset is basically provided with a portable box with snap fasteners and a storage function, a mobile power supply is integrated in the portable box, and the headset is automatically disconnected in the box when the power is off, so that the charging is started, and the real wireless headset is very convenient and pleasant (fig. 4(b) is a structural schematic diagram of the existing real wireless headset storage (charging) device). The stereo system is formed by the left earphone and the right earphone of the true wireless earphone through Bluetooth, and the listening, the communication and the wearing of songs are improved; meanwhile, functional characteristics of voice assistant, gesture control, active noise reduction and the like relative to technology are integrated in a plurality of TWS earphones, and more functions are brought. Along with the development of the real wireless earphone, the main loudspeaker and the auxiliary loudspeaker can realize free master-slave switching: (a) for single ear use: taking out the product for use, and taking out any single product for automatic starting and pairing; (b) binaural use: the two are taken out together and the two ears are paired for starting. The existing true wireless Bluetooth headsets are of various types. For example, the brand: millet (Mi), type: AirDots2 true wireless bluetooth headset TWSEJ061 LS; brand name: hua is, type: j18 true wireless Bluetooth headset, true wireless headsets freebuguds 3 i; brand name: apple, model: AirPods; brand name: easy cloud of the net, model: lite + upgrade ME01TWS Pro; brand name: BOSE, model: QC EARBUDS true wireless noise reduction earphone; brand name: ITreasure, model: a true wireless 5.1 Bluetooth headset; brand name: summer new AMOi, model: f9 bluetooth headset; brand name: loving, model: a1 true wireless bluetooth headset, brand: win Pisen, type: a true wireless Bluetooth headset T-Buds 3; and so on.
For some wireless headsets or true wireless headsets, the headset is sometimes easily lost (not found) because it is stand alone, usually small. Various wired mobile phone earphones, wireless mobile phone earphone brands and styles are arranged on electronic shopping websites such as the Jingdong, Taobao, Amazon and Shuduo. Books and periodicals, the internet (e.g., apps are known) and the like are introduced by more wired earphone, wireless earphone and true wireless bluetooth earphone technologies. The existing technologies such as wired earphone, wireless earphone, true wireless earphone, Bluetooth 5.0 and the like are more and more known by the vast public at home and abroad.
The mask is a daily use article which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to block harmful gas, particles, smell, spray, virus and the like because people generally have haze, epidemic situations and diseases in life, or are sanitary, do not want to speak, doctors in hospitals have working relations and the like, even only for the sake of good looking and the like. People can often see that people wear common masks, medical disposable masks, N95 masks, masks with breather valves and the like. For example, fig. 6 is a schematic view of a conventional mask. In the figure, 1 is the mask body, and 2 is the hangers on two sides. The mask body 1 covers the mouth and nose of a person and is used for filtering air, spray, viruses and the like entering the mouth and nose, and the hanging lugs 2 on the two sides are hung on ears of the person. Fig. 7 is a schematic view of another conventional mask (with a breather valve). In the figure, 1 is a mask body, 2 is a hanging lug, and 3 is a breather valve. The mask body 1 covers the mouth and nose of people, filters air entering the mouth and nose, blocks splashes, viruses and the like, the hanging lugs 2 on the two sides are hung on the ears of people, and the breathing valve is used for removing the breathing air as soon as possible, so that the portable breathing of people is facilitated.

The invention also provides a mobile phone, and a signal amplifying circuit is arranged between the microphone of the mobile phone and the signal processing circuit of the mobile phone.
The invention also adds a signal amplifying circuit between the microphone and the existing signal processing circuit of the existing earphone. The two-out switch is adopted to meet the requirement that a user can freely select the proper use habit of the mobile phone earphone. The adoption of the mask earphone is more beneficial to shortening the distance between the earphone (mobile phone) and the volume of the voice of the user. The general principle of the invention can be briefly described as follows:
the output voltage Ui of the signal collected by the microphone (original earphone) is input into a signal processing circuit, and the audio signal of the other mobile phone is obtained through a series of processing. The earphone of the invention adds a signal amplifying circuit between the output voltage Ui of the microphone collecting signal and the signal processing circuit, amplifies the tiny signal into an amplified signal or a normal audio signal, then inputs the amplified signal or the normal audio signal into the (original) signal processing circuit, because the original signal processing circuit can normally process the normal audio signal, although one party speaks in a whisper, the mobile phone party receiving the phone obtains the normal or amplified audio signal, namely, one party can obtain the normal or large volume audio signal even if the other party speaks in a whisper.
And secondly, considering that people have the right to select and use proper, proper and comfortable mobile phone earphones in different use occasions or environments, the invention adds the alternative switch, increases the use convenience of the mobile phone earphones and respects the earphone use habit of mobile phone earphone users.
(iii) (mask earphone):
(1) the mask body is worn on the mouth, so that the effects of protecting breathing, isolating germs and the like are achieved, and the diffusion of the speaking voice of the earphone of the mobile phone to the surrounding environment is prevented (hindered) on one hand (the mask can be used) to influence other people; meanwhile, the voice energy of a person can be gathered on the face mask (a mask) (a receiver/a microphone on the face mask) when the mobile phone makes a call, and the voice (collected voice) can be transmitted in a centralized mode (the ground).
(2) The mask earphone is worn on the ear, and the distance between the receiver of the common earphone and the mouth can be shortened, so that the sound loudness and the definition are improved.
(3) Voice communication can be clearly obtained while wearing the mask.
(3.1) the earphone is arranged on the mask, namely the user can make a call without taking off the mask, and the user can take off the mask inconveniently or unsanitarily (safely) in some special environments (the user sometimes takes off the mask to make a call in the prior art).
And (3.2) simultaneously, the mask ensures the definition of the call sound (in the prior art, the definition can be influenced by the call receiving and calling of the mask).
(3.3) hands are released, namely, when the hands are dirty, for example, when a doctor is polluted or inconvenient, the doctor can make a call without taking off the mask and wearing the mask; (meanwhile, because the receiver can be arranged in the mask, the mobile phone, the earphone (possibly some) and the mask are not polluted-compared with the case that the mask is taken off for making a call.); when riding a bicycle, take-away personnel, express little brother and the like can release both hands, and when riding the bicycle, the user can dial and answer a call to contact the client, thereby ensuring safe and clear conversation, reducing the acridity and the like (not recommended), and the like.
(4) The mask can release hands or necks (traditional telephone call, someone can hold the earphone wire or neck with hands to clamp the mobile phone/earphone, the invention can obtain clear sound and make telephone voice without holding the wired earphone wire with hands).
(5) The mask earphone can also comprise an alternative switch, and the user can freely select the mask earphone mode according to the environment, the conversation content and the like.
(6) Some gauze mask bodies can be opened, and the earphone inside, accessory can be dismantled, and convenient the washing also saves gauze mask earphone cost.
The invention has the beneficial effects that:
firstly, the invention solves the technical problem which is desired to be solved but is not successful all the time. As described above, people often want to have the technical problem that "when a phone and/or a phone earphone is used for a call, the other party (one party) can hear normal speech when the other party (one party) speaks loudly (" whisper "). The invention solves the technical problem that the opposite party of the minor talking of the present part can not hear normal talking when the mobile phone andor the earphone of the mobile phone talks, so that the opposite party of the minor talking of the present part can obtain normal or loud speaking volume when the mobile phone andor the earphone of the mobile phone talks.
1. The earphone also comprises a signal amplifying circuit structure additionally arranged between the microphone and the signal processing circuit of the existing earphone. The invention is characterized in that one party speaks in light sound/small sound (such as sound level of a mouse and a keyboard), a receiver receives the voice, the signal amplifying circuit amplifies the voice to normal conversation voice (the original/existing path is taken), the voice is sent out, the other party is normally called, and then the two parties have a very happy conversation. The present invention achieves the object (object) of the present invention by including the signal amplification circuit structure. (of course, get louder volume, it does not matter, the listener can choose to reduce the volume freely or not)
2. Compared with the prior art, the invention has different technical conception.
(2.1) the earphone in the prior art is improved at the receiving end (a receiver, a sound production unit of the earphone and a coil), and the invention is mainly improved at the transmitting end (the receiver end). The inventive idea is to improve the input signal (to normal or greater signal volume.) by one word, i.e. the prior art improvement focuses more on "listening" and the invention works on "speaking".
(2.2) generally, the overall design of the existing earphone considers how to design and select the audio from the background noise, and the application environment of the invention is quite quiet in a library, the background noise is very small, the problem of how to amplify the low volume under the condition that the background noise is not a problem (the background noise is basically zero), which is different from the existing (selected from the noise) that the main technical purpose, the technical scheme, the expected effect and the like are improved. (also, in the prior art, in the development of earphone technology, people usually focus on distortion-free and how to recover with high fidelity, and as mentioned above, recovery with high fidelity requires that one party receives a low-voice speech while the other party receives the low-voice speech, which is one of the meanings that recovery with high fidelity should have). The inventive idea of the invention is then not such, but the idea of the invention is that one party speaks bass and the other receives a (normal or loud speaking) signal, prior to (in preference to) receiving a fidelity audio signal from the other party ("high fidelity restoration"). In addition, as for the loud sound reception ("the other party receives loud sound"), the other party ("the other party") can freely turn down the volume of the horn. (if the phone is too loud, the volume of the phone can be freely adjusted, the volume is reduced-the invention is not damaged-in essence, if the volume of the phone connected to the opposite party is too loud, the phone is controlled to adjust the volume to be reduced in our life). Further, for example, when the opponent is an old person or the hearing is limited (weak), normal speech can be conversely made to have the effect of loud speaking (being heard), "parents who do not necessarily hear (are clear) the cell phone roar greatly" — the user can get loud sound with the parents (opponent) using the normal speech sound — without roaring greatly to the phone, the roar is not good in the sky — something is annoying to someone. The invention also has a good effect of solving the trouble smoothly. (the opposite side feels the sound big and can turn small.)
(2.3) as mentioned above, some people make a call (talk) in the office, and do not want to let others know the privacy or disturb others, and this party (party) speaks in a whisper (lower than normal talk sound, e.g. mouse click magnitude), and people around are not held or not heard clearly, however, the other party of the mobile phone listens clearly-speaks in a normal or loud voice, and does not affect people around, and the purpose that the privacy of the party does not want to let others know is achieved. Other scenes are similar to achieve the aim of the invention.
Second, the switch structure of the alternative of the invention. Compared with the prior art, the voice-activated voice switch further comprises an alternative switch structure in order to prevent the opposite side from getting larger voice interference to the opposite side when a user normally speaks and respect the use habit of the user. That is, in the normal call environment, the user pushes (selects) the "normal mode" through the one-out-of-two switch (key), and uses the original communication circuit to make a call: microphone-alternative switch-signal processing circuit … …, handset talk; when the 'small voice speaking and the other party getting normal or loud voice' are needed, the alternative switch (key) is pushed to (selects) the 'low voice mode', and the communication process is realized by adding an amplifying circuit, such as a microphone, the alternative switch, a signal amplifying circuit, a signal processing circuit, … …, a mobile phone, two parties realizing communication, and the like. On one hand, the normal speaking can be prevented from obtaining larger sound to interfere the other party (at this time, the user can select the 'normal mode', namely, the normal speaking of one party is avoided, and the other party obtains 'thunder sound'), on the other hand, when the user wants 'the own party speaks in a small voice and the other party obtains the normal sound', the 'low sound mode' needs to be used, and an alternative switch is designed, so that the use habit of the user according to different occasions (possible) is considered and respected. The earphone has the advantages that the earphone can be used flexibly and conveniently (the requirement that a user can freely select a proper use mode (habit and requirement) of the earphone of the mobile phone according to the environment and the like), one selling point (function) is added, the market sales competitiveness is added to the product, and the potential economic benefit of the earphone is huge in view of huge earphone market.
And thirdly, in order to achieve (obtain) a better invention purpose (effect), one party can obtain normal or loud speaking voice when speaking in a small voice. The invention also provides a structure of the mask earphone (namely, the earphone with the mask).
The mask earphone can be combined with the mask, namely the earphone is arranged on the mask.
1. The mask body is worn on the mouth to protect breathing, isolate germs and the like, the earphone is worn on the ear to send sound to the ear, the distance between a receiver of a common earphone and the mouth can be shortened, and the sound loudness and the definition are improved. Namely, the distance between the microphone (mic) (or called as a receiver) and the lips is shortened by the ear-hanging piece (mask), namely, the distance between the earphone (mobile phone) and the voice volume of the user can be shortened by the mask earphone, and the voice is easy to be transmitted by the microphone (namely, the voice is easy to be clear). (distance can guarantee clarity)
2. The invention (mask) can reduce the loss of sound volume (sound) loss, namely the effective volume enters the earphone receiver. (energy-gathering) microphone in mask for centralized and directional transmission)
3. The related privacy disclosure is avoided.
4. The mask body fixes the earphone wire, draws the distance between the sound production of the mouth and the sound reception of the microphone, (compared with the prior art), 'a hand holding device of the earphone wire' -the handle or the cheek neck is released, and the hand acid, the neck acid, the cheek acid and the like are released (hands, faces and the like are released) when the hands are inconvenient or the time is long; is convenient to use. (speaking to (in) the mask instead of to the mobile phone or the earphone)
6. (problem of safety and hygiene)
The invention can clearly obtain voice communication while wearing the mask. (because the receiver can be in the mask) when the hands are dirty, the mobile phone can be used for communication (the mobile phone is not polluted, the earphone (possibly) is not polluted, the mask is not polluted, and the user can take the phone call after taking off the mask). (hand pollution; optionally pollution mask)
The mask can be worn when the user uses the earphone to make a call, the user does not need to take off the mask (instead of taking off the mask, which is harmful to health, such as doctors or nurses in hospitals, catering service workers, people with high dust pollution to working environments and the like, and also can make a call in epidemic situations or other special conditions (for example, a doctor can make a call with a breathing mask without hands), and the sound can be clear. (wearing the mask while making a call to avoid infection of infectious diseases or dust entrance, self-sanitation and safety)
The water-saving toilet bowl is sanitary (for other people) and sanitary (can prevent messy water from flying at a call opening of canteen workers). (Prior art, not on the earphone, may need to take off the mask to make a call, sanitary, hand contamination.)
The pad can protect the mask from being sanitary.
7. Take away personnel, express delivery guy etc. release both hands, wear gauze mask health, can clear pronunciation contact customer when riding the car, clear conversation reduces painstakingly (compare with parking or hold the phone while riding the car).
8. Compared with the prior art, the microphone (on the mask) and the loudspeaker can be separated. In addition, for some of the present invention (for example, the mask + the wireless microphone + the wired speaker, etc.), since the speaker is connected with the signal data line (and the mask), (compared with the wireless earphone and the true wireless earphone in the prior art), the (earphone) is not easy to be lost (because the wired earphone and the mask) (the earphone) is not easy to be lost, namely, the (earphone) lost target is larger and is easy to be found.
9. The invention can be opened/closed on the existing mask body, and objects can be placed in the mask body. Can be used for placing the earphone parts of the mobile phone and can be opened, replaced and closed. The earphone accessory inside can be dismantled, conveniently washs. The cost of the mask earphone is also saved. The earphone is convenient to carry; meanwhile, the earphone is convenient to store.
10. The invention is a new product. The mobile phone earphone has huge market, is subdividing the market and has fierce competition, and the wearable earphone also has a wearable fashion concept and has good and positive market prospect. When the mask is regarded as a new product, the mask is also beneficial to the production development of mask related enterprises.
(II) (functional mutual support) As mentioned in (I), the mask and the earphone of the present invention functionally support each other, and achieve a new technical effect (the distance between the mouth (voice) and the earphone microphone is shortened, the earphone or the cheek clip is not required to be held by hand, the earphone voice effect is clearer, (the earphone is on the mask, or the earphone on the mask) is not required to be taken off), or it is obvious that the effect of the technical features of the present invention is superior to the sum of the effects of each of the technical features.
And (III) the mask earphone can also be a structure combining an earphone, a mask and an alternative switch.
As mentioned above, the invention can also be the combination of an earphone, a mask and a two-in-one switch. The alternative switch may also select enhanced call functionality ("whisper mode") or may select normal mode-both for special use cases (scenarios) and normal use cases. Three in one, not only give play to respective advantage, but also make things convenient for user's selection, function to promote each other and gain new positive effect jointly. (not only achieving the purposes of small voice call, privacy protection and the like, but also respecting the habit of users and reducing the interference of the other party caused by normal call.)
The invention also provides a mobile phone (the mobile phone with the amplifying circuit). The mobile phone can comprise a signal amplifying circuit and an alternative switch. The mobile phone can also solve the problem of puzzling people for years (one party can obtain normal or loud speaking voice when talking to the other party).
Fifthly, the mobile phone earphone market is huge, market subdivision is being carried out, and competition is fierce, namely the development time of the earphone is not long in the development of the whole audio industry, the user demand is continuously improved in the rising period at present, the expected value of the user to the earphone is also improved, so that a new test is provided for the industry, and the mobile phone earphone can be a new type/product; the present invention also incorporates wearable fashion concepts; the mask market can also become a new product; benefiting relevant enterprises; namely, the invention has good, larger and positive market prospect.
In a word, the invention solves the technical problem which puzzles people for many years, namely the invention solves the technical problem that when a mobile phone and/or a mobile phone earphone is in communication, the minor talking counterpart of the party can obtain normal or loud speaking volume (protecting privacy and avoiding interfering other people) and the like; the alternative switch structure gives more choices for users; the distance between the mouth (voice) and the earphone microphone is shortened by the mask earphone, the earphone or a cheek clamp does not need to be held by hand, and the voice effect of the earphone is clearer; the user can make a call without taking off the mask; releasing the hand; and so on, the mask and the earphone functionally support each other and achieve a new technical effect, or the effect of the technical features of the present invention is superior to the sum of the effects of each of the technical features; the mask can be used by many people, for example, people can use the mask (the invention) because of haze, epidemic situation and illness in life, or the mask is used by doctors in sanitation, do not want to speak, and in hospital because of working relations, and even can be worn only for the purpose of individuality and good look; when a doctor calls, the doctor can use the telephone without taking off the mask or picking up the earphone by hands when hands are polluted; the system is used by light sound in a library and is used when people do not want to interfere with other people on duty, and privacy is protected when people are on the subway and the use of other people is not interfered; take-out personnel and express little brother, release both hands, contact the customer and use, clear conversation, reduce the acrid and bitter, etc.; has huge market and good, larger and positive market prospect.
