Embodiment
With reference to accompanying drawing, and the present invention is described in detail based on embodiment.
Figure 1A represents that user (people played golf) 1 is equipped with the stereogram of the state of audio player 2 and sound volume control device 3.User 1 is equipped with the sound volume control device 3 be combined into one with audio player 2 at waist.The sound (such as, music) that the earphone 4 that user 1 while listen is connected with sound volume control device 3 sends, carries out the swing exercise of golf clubs.In addition, sound volume control device 3 is not must be combined as a whole with audio player 2.Such as, sound volume control device 3 also can be equipped in waist by user 1, and audio player 2 is remained on other positions of health.Further, in figure ia, although sound volume control device 3 is connected by electric wire with earphone 4, both also can be wireless.
Figure 1B is the block diagram of the structure representing audio player 2 and sound volume control device 3.Audio player 2 comprises: sound reproduction portion 22 and sound data store 24.Sound reproduction portion 22 reads the voice data stored in voice data storage part 24, and regenerates sound (musical sound etc.) according to this voice data.As voice data, MP3(dynamic image expert compression standard audio frequency aspect 3 can be adopted, MPEG Audio Layer-3) etc. Wave data form, or, comprise MIDI(digitlization instrumental interface, Musical Instrument Digital Interface) the SMF(standard MIDI format of information and event timing, Standard MIDI Format) etc. such performance data form.Audio player 2 exports the voice signal representing reproduced audio to sound volume control device 3.
Sound volume control device 3 comprises volume adjusting portion 32 and acceleration transducer 34.Acceleration transducer 34 also can be formed with sound volume control device 3 split.Volume adjusting portion 32 comprises volume adjusting handling part 322 and volume adjusting control part 324.Acceleration transducer 34 will represent that the output signal being applied to the acceleration of sound volume control device 3 is supplied to volume adjusting control part 324.Volume adjusting control part 324 generates volume-reducing signal AS according to the output signal of acceleration transducer 34, and outputs to volume adjusting handling part 322.Volume-reducing signal AS is the binary signal represented by " H " and " L " (that is, senior and rudimentary).In the whole frequency range of reproduced audio, volume adjusting handling part 322 is according to the volume-reducing signal AS of volume adjusting control part 324, and the voice signal in process sound reproduction portion 22 reduces to make volume.Specifically, when volume-reducing signal AS is " H ", volume adjusting handling part 322 carries out volume decrease reduction process.On the other hand, when volume-reducing signal AS is " L ", volume adjusting handling part 322 does not carry out volume decrease reduction process.At this, when the volume of reproduced audio is below setting, volume adjusting handling part 322 also can be not limited to the value of volume-reducing signal AS, does not carry out volume decrease reduction process.Thus, sound volume control device 3 regulates the volume of the voice signal of audio player 2 and supplies to earphone 4.The controlled sound of volume released by earphone 4.
In the present embodiment, after volume-reducing signal AS becomes " L " from " H ", volume adjusting handling part 322 pairs of voice signals process, and the volume of the reproduced audio that volume is lowered gradually increases and returns to original volume.That is, the volume of the reproduced audio be lowered due to volume is recovered gradually, therefore, after volume decrease reduction process, the volume due to reproduced audio can be suppressed to increase suddenly and the incongruity produced.But, gradually neither recover the volume of the reproduced audio that volume is lowered.
For convenience of description, in fig. ib, audio player 2 and sound volume control device 3 are separately described, but in fact, both functions are realized by the microcomputer (not shown) comprising CPU, ROM, RAM.That is, the function in sound reproduction portion 22 and volume adjusting portion 32 is realized by the program stored in CPU execution ROM or RAM.Further, the function of volume adjusting handling part 322 is realized by the electronic sound volume modulator that electronically can control attenuation.
Below, with reference to Fig. 2 A ~ Fig. 2 C, the relation between the size (hereinafter, referred to as " listening to volume ") of the action of user, volume-reducing signal AS and the actual sound heard of user is described.Fig. 2 A represents a series of the swing actions of user to golf clubs.When user swings to golf clubs, after (1) is got ready in advance, (2) are backswing motion from rear fork action, and golf club head arrives (3) summit.Then, start lower beam action by the upper lower beam switching motion carried out from (3) summit, (4) realized between golf club head and golf are clashed into.(4), after clashing into, through putting away sports equipment, action arrives (5) execution.Fig. 2 B represents the time variations of volume-reducing signal AS, and Fig. 2 C represents the time variations listening to volume.The transverse axis of Fig. 2 B and Fig. 2 C represents along with a series of shown in Fig. 2 A swing action and elapsed time.In fig. 2 c, solid line represents the time variations of the volume of reproduced audio, and dotted line represents (4) when clashing into, and the volume of the strike note (sound of playing ball) produced the shock of golf due to golf club head over time.
Usually, when two sound that frequency is close enter auditory system, little sound can be become by the elimination of large sound (it is called " sheltering device ") not to be heard (this phenomenon is called " sheltering ").When Fig. 3 represents that two sound of roughly same frequency enter auditory system, the acoustic pressure (sheltering grade) of the perception lower limit of little sound is along with the situation of time variations.In figure 3, horizontal axis representing time, the longitudinal axis represents acoustic pressure (sheltering grade).Further, solid line represents shelters grade, and dotted line represents the acoustic pressure (that is, sheltering grade) of sheltering device.At this, shelter device at moment t
0~ moment t
1during T
mproduce in (such as, 200ms).
As shown in Figure 3, the generation period T of device is being sheltered
m, shelter grade and uprise close grade (being called " simultaneous mask effect ") of sheltering the acoustic pressure of device.But, shelter grade and not only shelter the generation period T of device
m, sheltering the generation start time t of device
0also can uprise (this is called " backward masking ") before, shelter the generation finish time t of device
1also can uprise after just terminating (this is called " forward masking ").As shown in Figure 3, the generation start time t of device is being sheltered
0about 10ms before and shelter device produce finish time t
1about 50ms after, shelter grade and become very low.
In the present embodiment, considering the characteristic of above-mentioned auditory system, in order to allow user more reliably can hear strike note, and reducing the volume becoming the reproduced audio sheltering device.Particularly, as shown in Figure 2 B, if detect that user makes golf clubs upper boom to summit by acceleration transducer 34, carry out the upper lower beam switching motion of golf clubs afterwards, then volume-reducing signal AS is set as " H " by volume adjusting control part 324 in certain hour (such as, between 0.5 ~ 1 second).In addition, volume-reducing signal AS is set as that the time of " H " can be not necessarily.Such as, detected by acceleration transducer 34 after user has carried out the upper lower beam switching motion from summit of golf clubs put away sports equipment action or execution etc. time, volume-reducing signal AS can switch to " L " from " H " by volume adjusting control part 324.
Because volume adjusting handling part 322 is according to the volume of volume-reducing signal AS adjustment reproduced audio, therefore, as shown in Figure 2 C, if volume-reducing signal AS is switched to " H " from " L ", then the volume of reproduced audio reduces.On the other hand, if volume-reducing signal AS is switched to " L " from " H ", then the volume of reproduced audio increases to original volume gradually.As shown in Figure 2 C, when producing time delay in the process of volume adjusting handling part 322, the volume change of reproduced audio is slightly slower than the change of volume-reducing signal AS.
As mentioned above, the volume of reproduced audio starts to reduce after the moment (that is, arriving the moment on summit) being equivalent to lower beam required time ahead of time than the moment (that is, clashing into the moment) producing strike note.Usually, lower beam needs time of 0.05 ~ 0.1 second, therefore, by making the volume of reproduced audio reduce immediately after lower beam switching motion on having carried out golf clubs user, reproduced audio can be suppressed fully to the forward masking of strike note.Therefore, user more reliably can hear strike note.
In the present embodiment, with reference to Fig. 4 A, Fig. 4 B, swing in action to user at golf clubs, the detection from summit to upper lower beam switching motion is described.Fig. 4 A represents the direction of measurement of the acceleration of the waist of user.Here, the direction of rotation of waist when X-direction is lower beam, Y-direction is the direction along the backbone of user from waist to head, and Z-direction is the direction of the back ventrad from user.Fig. 4 B represent user carry out golf clubs swing action time X, Y, Z all directions the measurement result of acceleration.In figure 4b, transverse axis represents to be equivalent to clash into moment t
imoment " 0 " be benchmark time, the longitudinal axis represents the acceleration of X, Y, Z all directions.Here, solid line represents the time variations of the acceleration of X-direction, and dotted line represents the time variations of the acceleration of Y-direction, and chain-dotted line represents the time variations of the acceleration of Z-direction.
As shown in Figure 4 B, at the moment t that preliminary activities terminates
a(clash into moment t
iabout 0.28 second before), the acceleration of X, Y, Z all directions is stabilized in less value.User is at moment t
acarry out the preliminary activities of golf clubs, afterwards, once the backswing motion of golf clubs, the acceleration of X-direction will be partial to negative direction.User is at period T
bcarry out the backswing motion of golf clubs.The acceleration of X-direction is at upper boom period T
bmidway moment t
x(clash into moment t
iabout 0.14 second before) form the peak value of negative direction.At the upper boom period T of user to golf clubs
bfinish time t
t(clash into moment t
iabout 0.06 second before), golf clubs arrive summit.At this summit moment t
t, the acceleration of X-direction increases to " 0 " from negative direction.User starts the lower beam action of golf clubs at summit moment t, becomes period T during this lower beam
d.At this lower beam period T
d, the acceleration of X-direction increases from " 0 " to positive direction.In the finish time of user to the lower beam action of golf clubs, that is, clash into moment t
iafter (0 second), user is in order to carry out the action of putting away sports equipment of golf clubs, and the acceleration of X-direction is more partial to positive direction thus is formed peak value.Afterwards, the acceleration of X-direction declines rapidly.
The acceleration of Y-direction is at upper boom period T

tform the peak value of negative direction afterwards.Further, at shock moment t
iafterwards, the acceleration of Z-direction rises to " 0 " gradually.
Corresponding diagram 4B, simultaneously with reference to the flow chart shown in Fig. 5, is described the action that swings of golf clubs user.First, user holds golf clubs and confirms the relative position between itself and golf, carries out preliminary activities (step S1) simultaneously.In figure 4b, moment t is clashed into
ithe front time of about 0.5 second ~ 0.3 second is equivalent to preliminary activities.Afterwards, user makes golf clubs remain static, and carries out rear fork, at moment t
astart backswing motion (step S2).Moment t
alater upper boom period T
bbe divided into two time periods.At (that is, moment t of front half time period
a~ t
x), user from vertical direction gradually rearwardly side lift golf clubs.If golf clubs arrives the centre position of upper bar track, then at rear half time period (moment t
x~ t
t), user switches the upper boom direction of golf clubs and draws circular arc (step S3) to upside.Afterwards, user on head near upset wrist, make golf clubs towards horizontal direction, become vertex position (step S4).Afterwards, user carries out the lower beam action (step S5) of golf clubs.At moment t
i, golf club head and golf ball knock (step S6).After shock, user forwards takes advantage of a situation and brandishes golf clubs, carries out action (step S7) of putting away sports equipment.In the present embodiment, after step S4, sound volume control device 3 detects user to the upper lower beam switching motion (step S11) of golf clubs from summit.Taking this as an opportunity, and the volume that sound volume control device 3 implements reproduced audio reduces (step S12).After being continued until shock (step S6) between the volume decrease lowstand of reproduced audio.
Swing in action above-mentioned user to golf clubs, the acceleration of X-direction (direction of rotation of waist) is at upper boom period T
bmoment t
xsignificantly be partial to negative direction, afterwards, at summit moment t
tpositive direction is transformed into from negative direction.Utilize this characteristic, the acceleration of X-direction exceedes defined threshold (such as ,-10m/s in negative direction
2) after be transformed into positive direction from negative direction, by detecting this, user can be detected to the upper lower beam switching motion of golf clubs from summit.
In the present embodiment, utilize the change of the acceleration of X-direction, detect user to the upper lower beam switching motion of golf clubs from summit, in the certain hour from this detection moment, the volume of reproduced audio can reduce automatically.Thus, due to from than shock moment t
ibe equivalent to lower beam period T ahead of time
dthe moment of (such as, about 0.06 second), the volume of reproduced audio can reduce, therefore, it is possible to prevent strike note to be reproduced sound mask after shock.
As shown in Figure 4 B, at upper boom start time t
ain the past, 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 detecting that the golf clubs of user is in roughly static state, according to the change of the acceleration of X-direction, detect the upper lower beam switching motion of golf clubs, thus, can suppress is the upper lower beam switching motion of golf clubs by other actions (such as, the walking) error detection of user.
In the present embodiment, although pass through the change of the acceleration of X-direction, detect user to the upper lower beam switching motion of golf clubs, also can by being suitably combined with the acceleration of Y-direction or Z-direction, lower beam switching motion in detection.In the present embodiment, although from user to the volume reducing reproduced audio the moment of the upper lower beam switching motion of golf clubs, be not limited thereto.That is, as long as at shock moment t
imoment before, also can from upper boom period T
bin particular moment (that is, user is to the ad-hoc location in the backswing motion of golf clubs) start the volume reducing reproduced audio.
In the present embodiment, according to the output signal of acceleration transducer 34, detect user to the upper lower beam switching motion of golf clubs.Then, in the lower beam action that the upper lower beam switching motion of golf clubs is follow-up, the volume of reproduced audio is reduced, thereby, it is possible to prevent strike note from being sheltered by this reproduced audio.Usually, the people played golf is not by means of only the thoughts and feelings passing to wrist when golf club head and golf ball, also by listen to along with state when golf club head and golf ball (such as, the angle of face when golf club head and golf ball) and strike note that tonequality changes, judge whether batting is appropriate.According to the present embodiment, even if listen to reproduced audio user, while carry out golf clubs swing action time, also clearly can hear strike note, therefore, by this strike note can easily judge batting whether appropriate.
In addition, strike note is different from the kind (bar, an iron etc.) of golf clubs or manufacturer, and the frequency characteristic of strike note also can change along with the kind of the striking point of golf club head (impacting point) or golf.Therefore, use the golf clubs of regulation and golf to carry out strike test in advance, detect and the strike note analyzed when batting appropriate and strike note when batting incorrect.According to the result that above-mentioned detection is analyzed, select the frequency range that reduce volume according to the frequency distribution of strike note, determine that volume reduces scope.
Below the variation of the present embodiment is described.
(variation 1)
Although in the above-described embodiments, audio player 2 and sound volume control device 3 split are arranged, also in audio player 2, sound volume control device 3 can be installed, make both become single device.That is, also upper at the device (such as, smart mobile phone etc.) with acceleration transducer and sound regeneration function the application software realizing the function of sound volume control device 3 can be installed.When audio player 2 and sound volume control device 3 are set to single device, due to can by both function mounting at same circuit substrate, or the program of both same CPU execution can be utilized, therefore, also easily can realize volume adjusting control part 324 sound to be reduced signal AS and output to sound reproduction portion 22, and sound reproduction portion 22 reduces according to sound the process that signal AS regulates the volume of reproduced audio.In this example, also volume adjusting handling part 322 can be omitted.
(variation 2)
In the above-described embodiments, in order to easily implement volume decrease reduction process, in the whole frequency range of reproduced audio, reducing volume, but be not limited thereto.That is, also only volume can be reduced in a part of frequency range (volume reduction scope) of reproduced audio.Now, volume decrease reduction process can be implemented by the circuit being combined with filter and electronic sound volume.In addition, volume decrease reduction process also can have FIR(by installation and have limit for length's unit impulse response, Finite Impulse Response) program of filter function or DSP(Digital Signal Processing, Digital Signal Processor) realize.
Now, volume reduces the frequency content that scope considers strike note and the frequency characteristic of sheltering grade as follows determines, increase if that is, shelter the difference on the frequency that device (that is, reproduced audio) causes, acoustic pressure reduces.Usually, in strike note, the frequency content changed due to the crash situation along with golf club head and golf is mainly in the frequency range of about 4 ~ 8kHz, therefore, if setting volume reduce scope with make in about 4 ~ 8kHz to shelter grade fully little, then whether user just can judge to bat by strike note appropriate.Like this, reducing the volume of a part of frequency range of reproduced audio, instead of during the volume of whole frequency range, because reproduced audio reduces in volume change acoustically, therefore, user does not listen to the reproduced audio having carried out volume decrease reduction process with can having incongruity.
As the method for the volume of a part of frequency range of reduction reproduced audio, following two methods can be considered.First method is, also can reduce volume in the scope more than assigned frequency.Now, due to the volume reduction of the melody unit that the frequency content that inhibit primarily of bass zone is formed, user easily can hold the rhythm of the music heard.That is, because user the rhythm of combining music can carry out the action that swings of golf clubs, the having stable behavior that swings can be made.In addition, although there is the volume decrease reduction process of reproduced audio, the melody of music can be heard constantly, therefore, the music after user can listen to recovery naturally when reproduced audio returns to original volume, and there is no incongruity.
Second method reducing the volume of a part of frequency range of reproduced audio also to reduce the volume of the particular frequency range of sheltering strike note.Now, identical with first method, user easily can hold the rhythm of the music of listening.Second method can reduce the tonequality change of the reproduced audio that volume decrease reduction process causes further, and user can listen to reproduced audio and not have incongruity.In this, second method is better than first method.But second method needs to specify the frequency range of the kind of sheltering along with golf clubs or golf and the strike note changed, and realizes than first method difficulty.From the viewpoint of realizing possibility, first method be better than second method.
In second method, also can set the strike note of (when not hitting) when volume reduces scope to enable user hear that batting is incorrect.Now, obtain narrow owing to volume can be reduced range set, therefore, user does not hear reproduced audio with can having incongruity.In addition, in second method, can arrange adjustable range configuration part at sound volume control device 3, the golf clubs that this adjustable range configuration part is specified according to user (such as, the kind of a golf clubs such as bar or iron, or the model etc. of golf clubs) set specific frequency range.Now, obtain narrow owing to volume can be reduced range set, therefore, user does not hear reproduced audio with can having incongruity.
As long as sound volume control device 3 can reduce the volume of a part of reproduced audio.Such as, the volume of the reproduced audio of a sound channel in the reproduced audio of two sound channels in left and right can also be reduced.That is, due to be sequestered in volume reduce sound channel side auditory system in suppressed, therefore, user clearly can hear strike note.In addition, also can be that the such performance data of the 22 pairs of SMF forms in sound reproduction portion regenerates, audio player 22 regulates the volume of the reproduced audio of this such performance data along with volume-reducing signal AS.Now, sound reproduction portion 22 also can along with the part beyond volume-reducing signal AS reduction melody unit or high-frequency volume.Even if like this, user also can hold the rhythm of the music listened to, and the rhythm of combining music can carry out the action that swings of golf clubs.
(variation 3)
In the above-described embodiments, utilize the acceleration transducer 34 being equipped in user's waist to detect the upper lower beam switching motion swung in action of golf clubs, but be not limited to this.Also the various transducers (such as, action sensor) of the predetermined portion that can be equipped in user can be utilized to detect the upper lower beam switching motion swung in action of golf clubs.Such as, can utilize and can be equipped in the upper wrist of user or the acceleration transducer of wrist or angular transducer.Or, the pressure sensor on the glove for golf game of the palmar hand that can be equipped in user can be utilized.
(variation 4)
In the above-described embodiments, by detecting user to the upper lower beam switching motion swung in action of golf clubs, and in follow-up lower beam action, regulating the volume of reproduced audio, listening to strike note, but, be not limited thereto.That is, as long as detect the compulsory exercise (or, assigned position) of the golf clubs of user, and regulate the volume of reproduced audio in subsequent action.Such as, also by detecting user to the excellent up and down switching motion in the shot of baseball, and the volume of reproduced audio can be regulated in follow-up bat swing, the sound of playing ball when bat and ball impact is heard.Or toss action when utilizing tennis racket to serve a ball by detecting user, regulate the volume of reproduced audio in follow-up racked swing forward, strike note when enabling tennis racket and tennis clash into is heard.That is, the invention is not restricted to golf, also can detect compulsory exercise (or position) in various sports, and in subsequent action, regulate the volume of reproduced audio, with the strike note enabling user hear ball.
In addition, the invention is not restricted to above-described embodiment and variation, various change can be carried out in the invention scope that appended claims specifies.
Industrial applicibility
The present invention is to listen the strike note getting golf, and detects the upper lower beam switching motion that swing in action of user to golf clubs, thus reduces the invention of the volume of reproduced audio.Because in various ball game, square stance all can produce strike note, therefore, the present invention also can be applied to the ball game (such as, baseball or tennis) beyond golf.
