Description

Change the tuning component of earphone tone

Technical field

The utility model relates to the component that one kind can reduce medium-high frequency sound wave ingredient, in particular to one kind is assemblied on earphone The tuning component for reducing medium-high frequency sound wave output quantity.

Background technique

Currently, widely available with mobile phone, either wired earphone, bluetooth headset or headset have become most people Belongings, people can appreciate beautiful music by wearing earphone, understand real-time news or for reducing ring Invasion of the border noise to ear-drum.

As the requirement for enjoying musical qualities is continuously improved in people, requirement and poor quality of the user to earphone personalization sound quality Earphone increasingly payes attention to the injury of ear.

In general, sound wave has following characteristic:

1, loudness: the size (being commonly called as volume) of the subjective perceived sounds of people determines with a distance from sound source by " amplitude " and people, Amplitude is bigger, and loudness is bigger, and the distance of people and sound source is smaller, and loudness is bigger.

2, tone: the height (high pitch, bass) of sound is determined, frequency more high-pitched tone is higher by " frequency ".

3, tone color: also known as timbre refers to that the waveform of sound determines the tone color of sound.Characteristic of the sound because of different objects material And there are different characteristics, it has different timbres, waveform is then different.Typical tone color waveform has square wave, sawtooth wave, sine wave, impulse wave Deng.

4, musical sound: the well-regulated sound for allowing people's pleasure.

5, noise: from the point of view of physics, the sound that is issued when making random vibration by sounding body, it is considered that, all It is the sound for interfering people to work normally, learn and rest and plays the sound of interference effect to the sound to be listened of people.

6, tone, loudness and tone color are three main features of musical sound, and people are exactly to distinguish sound according to them.

7, the decaying of sound wave

One sound will be more and more fainter in communication process, i.e. the decaying of sound wave.The reason of causing acoustic attenuation have with Lower three:

1) diffusive attenuation

The sound wave that object vibration issues is propagated around, and acoustic wave energy, which is gradually spread apart, to be come.The diffusion of energy is so that unit Existing energy reduces on area, and the sound heard is with regard to faint.

Acoustic wave energy on unit area with sound source distance square and successively decrease.

2) attenuation by absorption

When sound wave is propagated in solid dielectric, due to medium viscosity and cause the interior friction between particle, to make A part of sound can be changed into thermal energy；Simultaneously as the heat transfer of medium, hot friendship is carried out between the dense and sparse part of medium It changes, so as to cause the loss of sound energy, here it is the absorbing phenomenons of medium.

Generally, it is considered that attenuation by absorption and frequency of sound wave is square directly proportional.

3) scatter attenuation

When there are nutty structure, (suspended particles, bubble in such as liquid, nutty structure in solid are lacked in medium Fall into, dopant etc.) caused by the decaying of sound wave claim scatter attenuation.

Generally, it is considered that scatter attenuation is directly proportional to the biquadratic of frequency when the size of particle is much smaller than wavelength；Work as particle When size is close with wavelength, scatter attenuation and frequency it is square directly proportional.

8, sensibility of the people to sound wave

Within the scope of the threshold of audibility, people are most sensitive to the sound of 1000Hz~4000Hz, to the tolerance of this range of sound Also relatively high.

Human auditory gradually decreases with the growth sensitivity at age.Young people such as 16 years old or so can hear 16kHz- The extremely high frequency sound of 20kHz or so；And 40 years old or so most of a middle-aged person can only hear 13kHz sound below, for height The susceptibility of frequency sound wave can be greatly reduced；The old man later for 60 years old, what is lost first is the sense of hearing to high-frequency sound, with The range of the growth anaudia at age gradually develops to low frequency direction, it is just influenced when expanding to the range of intermediate frequency to speech The sense of hearing of language.

In the natural environment, sound source (such as speaker) passes through sky to a distance, the sound that sound source issues is had between human ear Gas medium is directly propagated or is reflected into the sound in human ear through reflecting object, and low-frequency content higher-frequency content is more, this is because The acoustic attenuation of high frequency content is greater than caused by the acoustic attenuation of low-frequency content.And distance is very short between the loudspeaker and ear-drum of earphone, In the sound issued by loudspeaker, the decaying of sound wave is smaller, can nearly all be received by ear-drum.Arrived in the sound that certain sound source issues In the identical situation of the loudness of intelligent's ear, sound sound of the acoustic tones of ear-drum than being passed to ear-drum by external environment is passed to by earphone Adjust it is ear-piercing, especially it is this to young people feeling more very, therefore, for long-time wear earphone young people family for, sound In high fdrequency component not only will affect the sound quality of sound, also result in its sense of hearing decline.

Utility model content

It is matched the technical problem to be solved by the present invention is to provide a kind of and earphone and earphone horn height can be reduced The tuning component of the change earphone tone of frequency acoustic component.

Specific embodiment

The tuning component of the change earphone tone of the utility model is also because following reason generates:

1) adaptability of human ear

When people is in the sound of certain frequency range for a long time, the susceptibility of the frequency range will be reduced after a period of time, So thinking that sound compares shrillness when just listening earphone, the feeling of this shrillness will be slow in use for some time It dies away, for hearer, this is not meant to that excessive Hi-Mid does not injure hearer, only adapted to by hearer, In fact, this chronic injury still has.

2) conspicuousness of the sense of hearing

Mixing sound wave containing senior middle school's low-frequency range in usual music, when medium-high frequency section component therein is depressed (it is opposite with The component of middle bass is reduced) after, we are easier not hearing the low-frequency sound details not being depressed, and bass is easier to transfer people Mood, usual people the occasions such as bar strong bass stimulation under, people is easy to follow the rhythm of music to wring That Neck, user When listening song using earphone, the song liked if it is oneself, all can VOLUME UP listen to the bass details in music, experience music Rhythm.But with the raising of volume, wherein treble components can also increase therewith, be easy to cause hearing impairment.

As shown in figures 1 to 6, the tuning component of the change earphone tone of the utility model be by can to high frequency sound wave generate compared with Latex, rubber or the flexible plastic material decayed greatly are made and (latex, rubber and flexible plastic cement are known as soft material below), 6 can be covered for the tone tuning piece 4 of chip shape, the tuning of 3 shape of tuning cover 5 or earplug of sucker shape.

If background technology part is sayed, the thickness of dielectric material is different with transmission capacity of the hardness to different frequency sound wave, Dielectric material is thicker, and the sound wave being transmissive to is fewer, and dielectric material is softer, and the frequency of sound wave range wide being transmissive to is wider, such as The sound wave of the latex material of 0.1mm, 1kHz to 5kHz can be transmitted preferably, and the sound to the other frequencies for being higher than above-mentioned wave band The transmissivity of wave all can be lower, this is because high frequency sound wave in soft medium decaying increase caused by.

The tone tuning piece 4 (ginseng as shown in FIGS. 1 and 2) is sheet, by the soft material through leaching mould or injection molding or molding or note It moulds.It is installed between 1 loudspeaker 2 of earphone and earplug 3, shape is adapted to the section configuration of 1 inner cavity of earphone, can be Round, ellipse is semicircle.

The tone tuning piece 4 for being independently and separately setting is easy to daily replacement.

The tuning cover 5 (referring to shown in Fig. 3,4) be it is hood-like, production method is such as tone tuning piece 4.It is fixing piece, usually It is wrapped on the loudspeaker 2 of earphone 1 and is bonded together with loudspeaker 2.

The tuning covers the shell-like of 6 (referring to shown in Fig. 5,6) caps or single radial cut, and production method is such as tone tuning piece 4.It is also It is independently and separately the component of setting, when use is nested with outside the earplug 3 of earphone 1, is inserted into earhole later.

It is easily installed and can increase the frictional force between earhole inner wall, prevents earphone 1 from falling off.

The thickness of tuning component can make high frequency sound wave have biggish decaying in 0.01mm-0.5mm, the thickness range, and can Obtain the transmission of the middle low-frequency sound wave component of wider frequency range, the thickness of the utility model first choice 0.1mm.

The tuning component of the utility model is mountable on wired earphone 1, bluetooth headset 1 or headset, the size of earphone 1 It can be insert earphone 1 in insertion earhole, can also be the clamp lug formula earmuff being pressed on ear, can also be around ear around ear formula Earmuff.

The acoustic aperture 7 that the sound that 1-10 can be such that loudspeaker 2 issue passes through, sound are equipped in the middle section of the tuning component The aperture in hole 7 is in 0.1mm-5mm, and preferred scope is in 0.5mm-2.5mm.Acoustic aperture 7 on the corresponding tuning component of insert earphone 1 is few A bit, aperture can be with smaller, for the earphone 1 in earmuff, and 7 quantity of acoustic aperture can be some more, and corresponding aperture can be more greatly.

The sum of multiple 7 areas of acoustic aperture should be less than the 1/3 of the tuning component area on tuning component, in this way, just having obvious Tuning effect.

The tuning component of the utility model is different from the dust-proof mesh enclosure being arranged in existing earphone, dust-proof mesh enclosure be usually by Metal or hard plastic material are made into, and tuning component must be made by the flexible material with excellent sound absorption performance.Tuning portion Earphone horn is obviously separated to form two spaces by part with put-through channel between the ear-drum of people, and centre only stays the acoustic aperture 7 of setting to release Put a small amount of high frequency.

Acoustic aperture 7 can generate together when product soaks mould or injection molding or molding or injection molding injection molding, can also stamped cutting or sharp Light is cut into, can also the voluntarily aperture setting on non-porous tuning component by user.

Change acoustic aperture 7 aperture can change high frequency pass through component, get to ear since high frequency mainly passes through aperture Film, (the reflection diffracting power of low frequency is stronger compared to high frequency, and the ratio absorbed by tuning component is smaller) is so 1 volume of earphone is bigger When, opposite, the sound wave high frequency components that ear-drum receives are fewer, and therefore, the sound wave of transmission is folded with the sound wave of aperture direct projection After adding, the sense of hearing of hearer can be made to seem simpler and more honest, tone color is warmer.

A further improvement is that by the ratio of the thickness production of the neighboring area of the tone tuning piece 4, tuning cover 5 and tuning set 6 The thickness of middle section is big.By tuning component processing at not uniform thickness, such as some positions thickness, some positions are thin, can be by loudspeaker 2 Tone color is adjusted to required different tone colors.

A further improvement is that the inner surface production by the tone tuning piece 4, tuning cover 5 and tuning set 6 is corrugated.It is good Place is when tuning up 2 output volume of loudspeaker, and the resistance that can reduce the back-and-forth motion of tuning component (can exchange line when supper bass is strong Part has front and back impetus, moving forward and backward just as loudspeaker).

A further improvement is that male and fomale(M&F) is set by the inner surface of the tone tuning piece 4, tuning cover 5 and tuning set 6, it can Enhance its sound absorbing power (i.e. high frequency attenuation).

Recess is equipped on the periphery of the tuning cover 5 and 1 loudspeaker 2 of earphone can be assembled to the cyclic annular sound chamber in it, with convenient Loudspeaker 2 are fit directly on the ring-type sound chamber.

The tuning component of the utility model, user can go to select the tuning for being suitble to oneself tone color according to the practical hearing of oneself Component is worn, that is, oneself likes suitable tone color (sound quality), while can reduce the intensity of 1 direct sound wave of earphone, is protected Hearing.

Earphone 1 equipped with tuning component, middle bass reflex and transmission capacity are stronger, and high frequency reflection and transmission capacity compared with Difference, can only reach ear-drum by aperture, and high fdrequency component can be limited effectively.
