Embodiment
With reference to accompanying drawing, and based on embodiment the present invention is described in detail.
Figure 1A is the stereogram that expression user (people who plays golf) 1 is equipped with the state of audio player 2 and sound volume control device 3.User 1 is equipped with the sound volume control device 3 that is combined into one with audio player 2 at waist.User 1 listens the sound (for example, music) that the earphone 4 that is connected with sound volume control device 3 sends on one side, Yi Bian carry out the swing exercise of golf clubs.In addition, sound volume control device 3 is not to be combined as a whole with audio player 2.For example, user 1 also can be equipped in waist with sound volume control device 3, and audio player 2 is remained on other positions of health.And in Figure 1A, although sound volume control device 3 and earphone 4 are connected by electric wire, both also can be wireless.
Figure 1B is the block diagram of the structure of expression audio player 2 and sound volume control device 3.Audio player 2 comprises: sound reproduction section 22 and voice data storage part 24.Sound reproduction section 22 reads the voice data of storage in the voice data storage part 24, and according to this voice data sound (musical sound etc.) is regenerated.As voice data, can adopt MP3(dynamic image expert compression standard audio frequency aspect 3, MPEG Audio Layer-3) the Wave data form such as, perhaps, comprise MIDI(digitlization instrumental interface, Musical Instrument Digital Interface) the SMF(standard midi format of information and event timing, Standard MIDI Format) the such performance data form such as.Audio player 2 is to the voice signal of sound volume control device 3 output expression regeneration sound.
Sound volume control device 3 comprises volume adjusting section 32 and acceleration transducer 34.Acceleration transducer 34 also can consist of with sound volume control device 3 splits.Volume adjusting section 32 comprises volume adjusting handling part 322 and volume adjusting control part 324.Acceleration transducer 34 supplies to volume adjusting control part 324 with the output signal that expression is applied to the acceleration of sound volume control device 3.Volume adjusting control part 324 generates volume decrease low signal AS according to the output signal of acceleration transducer 34, and outputs to volume adjusting handling part 322.Volume decrease low signal AS is the binary signal by " H " and " L " (that is, senior and rudimentary) expression.In the whole frequency range of regeneration sound, volume adjusting handling part 322 is processed the voice signal of sound reproduction section 22 so that the volume reduction according to the volume decrease low signal AS of volume adjusting control part 324.Specifically, when volume decrease low signal AS was " H ", volume adjusting handling part 322 carried out the volume decrease reduction process.On the other hand, when volume decrease low signal AS was " L ", volume adjusting handling part 322 did not carry out the volume decrease reduction process.At this, regeneration sound volume when setting is following, volume adjusting handling part 322 also can be not limited to the value of volume decrease low signal AS, does not carry out the volume decrease reduction process.Thus, sound volume control device 3 regulate audio players 2 voice signal volume and supply with to earphone 4.Earphone 4 is emitted the controlled sound of volume.
In the present embodiment, after volume decrease low signal AS became " L " from " H ", 322 pairs of voice signals of volume adjusting handling part were processed, and the volume of the regeneration sound that volume is lowered is increased gradually and return to original volume.That is, because the volume of the regeneration sound that volume is lowered is recovered gradually, therefore, after the volume decrease reduction process, can suppress to increase suddenly the inharmonious sense that produces owing to the volume of regeneration sound.Yet, neither gradually recover the volume of the regeneration sound that volume is lowered.
For convenience of description, in Figure 1B, audio player 2 and sound volume control device 3 are separately described, yet in fact, both functions are realized by the microcomputer that comprises CPU, ROM, RAM (not shown).That is, the function of sound reproduction section 22 and volume adjusting section 32 realizes by the program of storing among CPU execution ROM or the RAM.And the function of volume adjusting handling part 322 is by the electronic sound volume modulator realization that can control in the electronics mode attenuation.
Below, with reference to Fig. 2 A～Fig. 2 C, the relation between the size of user's action, volume decrease low signal AS and the actual sound of hearing of user (below, be called " listening to volume ") is described.Fig. 2 A represents that the user is to a series of actions that swing of golf clubs.When the user swung to golf clubs, after (1) was got ready in advance, (2) from the action of rear fork action beginning upper boom, golf club head arrived (3) summit.Then, begin the lower beam action by the upper lower beam switching motion that carries out from (3) summit, realize (4) bump between golf club head and the golf.(4) behind the bump, action arrives (5) execution through putting away sports equipment.Fig. 2 B represents the time variation of volume decrease low signal AS, and Fig. 2 C represents that the time of listening to volume changes.The transverse axis of Fig. 2 B and Fig. 2 C represents along with a series of the swinging shown in Fig. 2 A moved and elapsed time.In Fig. 2 C, solid line represent to regenerate time of volume of sound changes, and when dotted line represented (4) bump, the volume of (play ball) over time because the strike note that golf club head produces the bump of golf.
Usually, when two close sound of frequency entered auditory system, little sound can be become by large sound (it is called " sheltering device ") elimination and not hear (this phenomenon is called " sheltering ").When Fig. 3 represents that roughly two sound of same frequency enter auditory system, the situation that the acoustic pressure (sheltering grade) of the perception lower limit of little sound changed along with the time.In Fig. 3, transverse axis represents the time, and the longitudinal axis represents acoustic pressure (sheltering grade).And solid line represents to shelter grade, and dotted line represents to shelter the acoustic pressure (that is, sheltering grade) of device.At this, shelter device at moment t

1Also can uprise (this is called " forward masking ") after just having finished.As shown in Figure 3, sheltering the generation t zero hour of device
0About 10ms before and shelter device and produce the t finish time
1About 50ms after, shelter grade and become very low.
In the present embodiment, consider the characteristic of above-mentioned auditory system, in order to allow the user can hear more reliably strike note, and reduce the volume that becomes the regeneration sound of sheltering device.Particularly, shown in Fig. 2 B, make the golf clubs upper boom to the limit if detect the user by acceleration transducer 34, carried out afterwards the upper lower beam switching motion of golf clubs, then volume adjusting control part 324 is set as " H " with volume decrease low signal AS in certain hour (for example, between 0.5～1 second).In addition, volume decrease low signal AS being set as time of " H " can be not necessarily.For example, during put away sports equipment action or the execution after detecting the user by acceleration transducer 34 and carried out the upper lower beam switching motion that begins from the summit of golf clubs etc., volume adjusting control part 324 can switch to " L " from " H " with volume decrease low signal AS.
Because the volume that volume adjusting handling part 322 is regulated regeneration sound according to volume decrease low signal AS, therefore, shown in Fig. 2 C, if volume decrease low signal AS switches to " H " from " L ", the volume of the sound of then regenerating reduces.On the other hand, if volume decrease low signal AS switches to " L " from " H ", the volume of the sound of then regenerating increases to original volume gradually.Shown in Fig. 2 C, in the processing of volume adjusting handling part 322, produce in the situation of time-delay, the volume change of regeneration sound is slightly slower than the variation of volume decrease low signal AS.
As mentioned above, the volume of regeneration sound began to reduce after the moment (that is, arriving the moment on summit) that is equivalent to ahead of time the lower beam required time than the moment that produces strike note (that is, bump constantly).Usually, lower beam needs 0.05～0.1 second time, therefore, reduces by the volume that makes immediately regeneration sound after the lower beam switching motion on the user has carried out golf clubs, can suppress fully the forward masking of sound to strike note of regenerating.Therefore, the user can hear strike note more reliably.
In the present embodiment, with reference to Fig. 4 A, Fig. 4 B, the user in the action that swings of golf clubs, is described to the detection the upper lower beam switching motion from the summit.Fig. 4 A represents the direction of measurement of acceleration of user's waist.Here, the direction of rotation of the waist when directions X is lower beam, Y-direction are the direction of backbone from waist to head along the user, and the Z direction is the direction from user's back ventrad.Fig. 4 B is illustrated in the measurement result of acceleration that the user carries out swing when action X, Y, the Z all directions of golf clubs.In Fig. 4 B, transverse axis represents to be equivalent to constantly t of bump
IThe moment " 0 " be the time of benchmark, the longitudinal axis represents the acceleration of X, Y, Z all directions.Here, solid line represents the time variation of the acceleration of directions X, and dotted line represents the time variation of the acceleration of Y-direction, and chain-dotted line represents that the time of the acceleration of Z direction changes.
Shown in Fig. 4 B, at the moment t of preliminary activities end
A(bump is t constantly
IAbout 0.28 second before), the acceleration of X, Y, Z all directions is stabilized in less value.The user is at moment t

IAfterwards, the acceleration of Z direction rises to " 0 " gradually.
Corresponding diagram 4B simultaneously with reference to flow chart shown in Figure 5, describes the action that swings of golf clubs the user.At first, the user hold golf clubs and confirm it and golf between relative position, carry out simultaneously preliminary activities (step S1).In Fig. 4 B, bump is t constantly
IFront about 0.5 second ~ 0.3 second time is equivalent to preliminary activities.Afterwards, the user remains static golf clubs, carries out rear fork, at moment t
ABeginning upper boom action (step S2).Moment t
AT during the later upper boom
BBe divided into two time periods.At (that is, the moment t of front half time period
A～t
X), the user lifts golf clubs to rear side gradually from vertical direction.If golf clubs arrives the centre position of upper bar track, then at the (moment t of rear half time period
X～t
T), the user is switched the upper boom direction of golf clubs and is drawn circular arc (step S3) to upside.Afterwards, the user is the upset wrist near on the head, makes golf clubs towards horizontal direction, becomes vertex position (step S4).Afterwards, the user carries out the lower beam action (step S5) of golf clubs.At moment t
I, golf club head and golf clash into knock (step S6).Behind the bump, the user forwards takes advantage of a situation and brandishes golf clubs, the action (step S7) of putting away sports equipment.In the present embodiment, behind step S4, sound volume control device 3 detects the upper lower beam switching motion (step S11) that the user begins from the summit golf clubs.Taking this as an opportunity, and the volume that sound volume control device 3 is implemented regeneration sound reduces (step S12).After being continued until bump (step S6) between the volume decrease lowstand of regeneration sound.
In the swing action of above-mentioned user to golf clubs, acceleration T during upper boom of directions X (direction of rotation of waist)
BMoment t
XSignificantly be partial to negative direction, afterwards, at summit moment t
TBe transformed into positive direction from negative direction.Utilize this specific character, the acceleration of directions X negative direction surpass defined threshold (for example ,-10m/s
2) be transformed into positive direction from negative direction afterwards, by this is detected, can detect the upper lower beam switching motion that the user begins from the summit golf clubs.
In the present embodiment, utilize the variation of the acceleration of directions X, detect the upper lower beam switching motion that the user begins from the summit golf clubs, certainly should detect in the certain hour constantly, the volume of regeneration sound can reduce automatically.Thus, because from than bump t constantly
IBe equivalent to ahead of time T during the lower beam
D(for example, about 0.06 second) the time be carved into bump after, regeneration sound volume can reduce, therefore, can prevent that strike note is reproduced sound mask.
Shown in Fig. 4 B, at the upper boom t zero hour
AIn the past, the user carries out the preliminary activities of golf clubs, and during this period, the acceleration of X, Y, Z all directions is stabilized in less value.Like this, after the golf clubs that detects the user is in roughly static state, variation according to the acceleration of directions X, detect the upper lower beam switching motion of golf clubs, thus, other actions (for example, walking) error detection that can suppress the user is the upper lower beam switching motion of golf clubs.
In the present embodiment, although the variation of the acceleration by directions X detects the user to the upper lower beam switching motion of golf clubs, also can by with the suitable combination of acceleration of Y-direction or Z direction, lower beam switching motion in the detection.In the present embodiment, although from the user moment of the upper lower beam switching motion of golf clubs is begun to reduce the volume of regeneration sound, be not limited to this.That is, so long as at bump moment t
IThe moment before gets final product, also can be from T during the upper boom
BIn particular moment (that is, the user is to the ad-hoc location in the action of the upper boom of golf clubs) begin to reduce the volume of regeneration sound.
In the present embodiment, according to the output signal of acceleration transducer 34, detect the user to the upper lower beam switching motion of golf clubs.Then, in the follow-up lower beam action of the upper lower beam switching motion of golf clubs, reduce the volume of regeneration sound, thus, can prevent that strike note is by this sound mask of regenerating.Usually, the people who plays golf passes to the thoughts and feelings of wrist when not only clashing into by golf club head and golf, also the state when listening to along with golf club head and golf bump (for example, the angle of face during golf club head and golf bump) and the strike note that tonequality changes judges whether batting is appropriate.According to present embodiment, even on one side listen to regeneration sound the user, Yi Bian carry out when action of swinging of golf clubs, also strike note can be heard clearly, therefore, can judge easily by this strike note whether batting is appropriate.
In addition, strike note is along with the kind of golf clubs (bar, iron etc.) or manufacturer and difference, and the frequency characteristic of strike note also can be along with the kind of the striking point (exciting point) of golf club head or golf and changed.Therefore, use golf clubs and the golf of regulation to hit test, the strike note the when strike note when detection and analysis batting are appropriate and batting are incorrect in advance.Result according to above-mentioned detection is analyzed according to the selected frequency range that should reduce volume of the frequency distribution of strike note, determines that volume reduces scope.
The below describes the variation of present embodiment.
(variation 1)
Although in the above-described embodiments, with audio player 2 and sound volume control device 3 split settings, also can sound volume control device 3 be installed in audio player 2, make both become single device.That is, also can be in the upper application software that the function that realizes sound volume control device 3 is installed of the device with acceleration transducer and sound regeneration function (for example, smart mobile phone etc.).When audio player 2 and sound volume control device 3 are set to single device, because can be with both function mounting at same circuit substrate, perhaps can utilize same CPU to carry out both programs, therefore, can realize easily that also volume adjusting control part 324 reduces signal AS with sound and outputs to sound reproduction section 22, and sound reproduction section 22 reduces the processing that signal AS regulates the volume of regeneration sound according to sound.In this example, also can omit volume adjusting handling part 322.
(variation 2)
In the above-described embodiments, in order easily to implement the volume decrease reduction process, in the whole frequency range of regeneration sound, reduce volume, but be not limited to this.That is, also can only in a part of frequency range (volume reduction scope) of regeneration sound, reduce volume.At this moment, the volume decrease reduction process can be implemented by the circuit that is combined with filter and electronic sound volume.In addition, the volume decrease reduction process also can have FIR(by installation limit for length's unit impulse response is arranged, Finite Impulse Response) program or the DSP(Digital Signal Processing of filter function, Digital Signal Processor) realize.
At this moment, volume reduction scope considers that the frequency content of strike note and following frequency characteristic of sheltering grade determine,, increases then that acoustic pressure reduces if shelter difference on the frequency that device (that is, regeneration sound) causes that is.Usually, in strike note, the frequency content that changes owing to the crash situation along with golf club head and golf is mainly in the frequency range of about 4 ~ 8kHz, therefore, if set that volume reduces scope so that among about 4～8kHz to shelter grade fully little, then the user just can by strike note judge bat whether appropriate.Like this, in the volume of a part of frequency range that reduces regeneration sound, rather than during the volume of whole frequency range, because regeneration sound reduces in acoustically volume change, therefore, the user can not have inharmonious sense ground to listen to the regeneration sound that has carried out the volume decrease reduction process.
As the method for the volume of a part of frequency range that reduces regeneration sound, can consider following two methods.First method is also can reduce volume in the scope more than assigned frequency.At this moment, owing to suppressed mainly the volume reduction of the melody unit that the frequency content by bass zone forms, the user can easily hold the rhythm of the music of hearing.That is, because the rhythm that the user can combining music carries out the action that swings of golf clubs, can make the having stable behavior that swings.In addition, although the volume decrease reduction process of regeneration sound is arranged, can hear constantly the melody of music, therefore, the music the user can listen to recovery naturally when regeneration sound returns to original volume after, and do not have inharmonious sense.
Second method of the volume of a part of frequency range of reduction regeneration sound is also to reduce the volume of the particular frequency range of sheltering strike note.At this moment, identical with first method, the user can easily hold the rhythm of the music of listening.The tonequality that second method can further reduce the regeneration sound that the volume decrease reduction process causes changes, and the user can listen to regeneration sound and not have inharmonious sense.In this, second method is better than first method.Yet second method need to specify the frequency range of sheltering the strike note that changes along with the kind of golf clubs or golf, realizes than first method is difficult.From realizing the aspect of possibility, first method is better than second method.
In second method, also can set volume reduction scope so that the user can hear the strike note of (when not hitting) when batting is incorrect.At this moment, owing to can set volume reduction scope narrow, therefore, the user can not have inharmonious sense ground to hear regeneration sound.In addition, in second method, can the adjustable range configuration part be set at sound volume control device 3, this adjustable range configuration part according to the golf clubs of user's appointment (for example, the kind of the golf clubs such as bar or iron, or the model of golf clubs etc.) set specific frequency range.At this moment, owing to can set volume reduction scope narrow, therefore, the user can not have inharmonious sense ground to hear regeneration sound.
As long as sound volume control device 3 can reduce the volume of part regeneration sound.For example, also can reduce about the volume of the regeneration sound of a sound channel in the regeneration sound of two sound channels.That is, suppressed in the auditory system owing to the sound channel side that is sequestered in the volume reduction, therefore, the user can clearly hear strike note.In addition, also can be that the such performance data of 22 pairs of SMF forms of sound reproduction section is regenerated, audio player 22 is regulated the volume of the regeneration sound of this such performance data along with volume decrease low signal AS.At this moment, sound reproduction section 22 also can be along with volume decrease low signal AS reduces melody unit part or high-frequency volume in addition.Even like this, the user also can hold the rhythm of the music of listening to, and rhythm that can combining music carries out the action that swings of golf clubs.
(variation 3)
In the above-described embodiments, utilize the acceleration transducer 34 be equipped in user's waist to detect upper lower beam switching motion in the action that swings of golf clubs, yet be not limited to this.Also can utilize the various transducers (for example, action sensor) at the regulation position that can be equipped in the user to detect upper lower beam switching motion in the action that swings of golf clubs.For example, can utilize the upper wrist that can be equipped in the user or acceleration transducer or the angular transducer of wrist.Perhaps, can utilize pressure sensor on the glove for golf game of the palmar hand that can be equipped in the user.
(variation 4)
In the above-described embodiments, by detecting the user to the upper lower beam switching motion in the action that swings of golf clubs, and the volume of in follow-up lower beam action, regulating regeneration sound, listen to strike note, yet, be not limited to this.That is, as long as detect the compulsory exercise (perhaps, assigned position) of user's golf clubs, and the volume of adjusting regeneration sound gets final product in subsequent action.For example, also can pass through to detect the user to the up and down excellent switching motion in the shot of baseball, and the volume of in follow-up bat swing, regulating regeneration sound, the sound of playing ball when making bat and ball impact can be heard.Perhaps, the toss action when utilizing the tennis racket service by detecting the user, the volume of in follow-up forward racked swing, regulating regeneration sound, the strike note when making tennis racket and tennis bump can be heard.That is the user, the invention is not restricted to golf, also can in various sports, detect compulsory exercise (or position), and in subsequent action, regulate the volume of regeneration sound, so that can hear the strike note of ball.
In addition, the invention is not restricted to above-described embodiment and variation, can in the invention scope of appended claims regulation, carry out various changes.
Industrial applicibility
