Description

  The present invention relates to an acoustic system that automatically reproduces content such as appropriate music / voice according to a user's physical condition, health condition such as mental condition.

Currently, there are many contents such as music and audio provided on the market, and it may be difficult for the user to select content suitable for himself. Therefore, a technique for supporting selection of content has been developed. For example, the system of Patent Document 1 analyzes music selected by the user in the past, and newly recommends other music based on the analysis data. Then, the user selects the optimum music from the recommended music. According to this system, the user can easily select music that suits his / her preference from among a large number of music.
Special table 2007-508636

  In the system of Patent Document 1, music is recommended according to the user's preference analyzed based on the past history. For this reason, for example, even when the user feels tired, simple and rhythmic music with a fast tempo may be selected. In such a case, there is a possibility that breathing, blood pressure, pulse, etc. will increase and fatigue will increase. Is also possible. In addition, since it is necessary for the user himself to select music in the end, it may be troublesome.

  The main object of the present invention is to provide a technology for automatically reproducing contents such as music and voice that are objectively suitable for the health condition such as the physical condition and mental state of the user.

  The present invention employs the following means in order to solve the above problems.

  That is, the first means includes a content database storing a suitable health condition for a plurality of sound contents suitable for each health condition, a health condition analyzing means for analyzing the health condition based on the user's biological information, and the health condition. A sound content selection unit that selects sound content from the content database based on the health state analyzed by the analysis unit, and a sound content reproduction device that reproduces the sound content selected by the sound content selection unit.

  “Sound content” includes all contents composed of sound, such as music, natural sounds, and artificially created sounds. There are various possible units of “sound content”. For example, one track (one song) can be regarded as one unit, and three tracks (three songs) can be regarded as one unit. Alternatively, one album may be regarded as one unit, and further, a unit divided by a predetermined time unit (for example, 3 minutes, 10 minutes, etc.) can be considered as one unit. In addition, the “health state” means a physical condition (for example, a normal state, a fatigue state, a sick state, etc.), a mental state (for example, a relaxed state, a tension state, a sleep state, etc.).

  The user's health condition is analyzed based on biological information such as pulse, body movement, skin temperature, skin potential, body weight, body fat, body temperature, bone density and the like. Each sound content has unique characteristics such as frequency, volume level, rhythm, tempo, and the like, a repeated pattern of chord progression, and a rising section, and each has a suitable health condition. For example, sound content with a relaxed tempo is said to be suitable for relieving tension, and the content database stores a health state suitable for each sound content. According to the first means, since the sound content is selected based on the user's health state analyzed from the biological information, the sound content that is objectively suitable for the user's health state does not bother the user. Played.

  Like the 2nd means, it is preferable that the said content database has memorize | stored the sound content suitable for each user for every user. The sound content suitable for each user is selected from the sound content recommended based on the user's preference by the technique described in Patent Document 1, for example, or the sound content recommended based on attributes such as the user's age and sex The content is stored in the content database by selecting from the content or by the user selecting by himself.

  The third means includes an input means for accepting an input operation by a user, and the content database receives an operation for adjusting the sound content during the sound content reproduction by the sound content reproduction apparatus. The sound content, the content adjusted by the operation, and the user's health status at that time are stored in association with each other.

  During playback of the selected sound content, if the user makes an input operation that adjusts the cut of the specific range, rhythm / tempo change, etc., or changes to other sound content, it becomes the operation target The sound content, the adjustment content or the changed sound content, and the health state at that time are associated with each other and stored in the content database. Thereby, data more reflecting the user's preference is accumulated.

  Note that the information stored in the database by the third means includes the health condition. For this reason, the sound content selection means can select the sound content based on these health conditions, and the sound content more suitable for the user's preference is selected.

  The fourth means comprises listening purpose estimation means for estimating the listening purpose of the sound content based on the health condition of the user, and the content database further stores sound content suitable for each listening purpose, and the sound content The selection means selects sound content from the content database based on the listening purpose estimated by the listening purpose estimation means.

  Based on the user's physical condition (for example, normal state, fatigue state, illness state, etc.) and mental state (for example, relaxed state, tension state, sleep state, etc.), the purpose of listening that the user would like is estimated can do. For example, when the user's mental state is analyzed as a tension state, the purpose of listening “to relax” is estimated. On the other hand, each sound content has unique characteristics such as frequency, volume level, rhythm, tempo, and the like, a repetitive pattern of chord progression, and a rising section, and each has a suitable listening purpose. For example, sound content with a relaxed tempo is suitable for listening for the purpose of relaxation, and the listening purpose suitable for each sound content is stored in the content database. According to the fourth means, since the sound content suitable for the listening purpose estimated from the user's health condition is automatically selected, the sound content suitable for the user's health condition is objectively reproduced.

  In the fifth means, the sound content is provided with a segment for each unit of the scheduled reproduction order, and the health condition analysis means is selected and reproduced by the sound content selection means. Is analyzed, the user's health condition is analyzed, and based on the analyzed health condition, the degree of the effect of the listening purpose estimated by the listening purpose estimation means is determined. The listening purpose suitable for each sound content is rewritten, reflecting the degree of the effect of the listening purpose.

  As a unit of sound content, for example, one track (one song), three tracks (three songs), one album, a predetermined time unit (eg, 3 minutes, 10 minutes, etc.) can be considered, and each unit of the scheduled playback order Is provided with a separator. Then, when the sound content suitable for the purpose of listening estimated based on the user's health condition reaches the break, it is determined how much effect has actually been, and by rewriting the data to reflect the degree, A more accurate content database is constructed.

  Sixth means includes user specifying means for specifying a user who exists in a range where the sound content reproduced by the sound content reproducing apparatus can be heard, and the content database is the listening purpose determined by the health condition analyzing means. For sound content that has a high degree of effect for a plurality of users, information to that effect is associated and stored, and the sound content selecting means is used when the user specifying means specifies a plurality of users, or the listening When a user whose degree of the target effect has not been determined is identified, sound content having a high level of the determined target effect for a plurality of users is selected from the content database.

  A sound content having a high level of effect for listening purposes for a plurality of users can generally be estimated as a sound content having a high level of effect (high versatility). Therefore, when it is necessary to reproduce a plurality of users or when it is necessary to reproduce a user whose effect for listening is unknown, it is less difficult to select such sound contents. it is conceivable that.

  In the seventh means, the user specifying means further specifies attributes such as a user's age, gender, etc., and in the content database, the effect of the determined listening purpose effect for a plurality of users having the same attribute group. Reflecting the degree, the listening purpose corresponding to each sound content is rewritten.

  In the seventh means, the listening purpose suitable for each sound content is rewritten, reflecting the degree of the effect of the listening purpose determined for a plurality of users having the same attribute group such as age and gender. As a result, a content database reflecting the degree of effect of user attributes is constructed.

  The eighth means comprises external condition information acquisition means for acquiring information on external conditions such as date and time, weather, etc., and the content database further stores sound content suitable for each of the external conditions, and the sound content selection The means selects sound content from the content database based on the external condition information acquired by the external condition information acquisition means.

  Information on external conditions such as date and time, weather, and the like can be acquired by, for example, a clock function and a calendar function, or from the Internet. Each sound content has its own characteristics such as frequency, volume level, rhythm, tempo, etc., repetitive pattern of chord progression and excitement section, etc., and external conditions such as time zone, season, weather etc. are suitable for each. is there. For example, sound content with a bright tone and fast tempo is considered suitable for summer, and the content database stores external conditions suitable for each sound content. According to the eighth means, the sound content suitable for the external condition is selected, and the sound content more suitable for TPO is reproduced.

  According to a ninth means, at least one of a wall, a floor, a ceiling, or a fitting of a space in which the sound content playback device is arranged is configured by a porous structure, and an actuator is attached to the surface. The opening area of the hole was adjustable.

  For example, if at least one of the base material or the finishing material of the face material is translated in the flat surface direction, the position of the hole group of the base material and the position of the hole group of the finishing material can be matched or shifted. . Thereby, for example, when a high volume content is reproduced, the position of the hole group of the base material and the position of the hole group of the finishing material may be matched to enlarge the opening area of the hole part and reduce the sound reflectance. it can. On the other hand, for example, when content with a small volume is played back, the position of the hole group of the base material and the position of the hole group of the finishing material can be shifted to close the hole portion and increase the sound reflectance.

  The tenth means is applied to a building having a plurality of internal spaces, and reproduces sound content for each internal space in which the sound content reproduction device is arranged.

  For example, there may be cases where a plurality of users are in different internal spaces and do not want to play the same sound content uniformly throughout the building. According to the tenth means, different sound contents can be reproduced in accordance with a user who is in an internal space (room, corridor, etc.) where the sound content reproducing apparatus is arranged.

  Hereinafter, an embodiment of an acoustic system according to the present invention will be described with reference to the drawings. First, a floor plan example of each floor in a two-story house to which the acoustic system of the present embodiment is applied will be described with reference to FIG.

  As shown in FIG. 1, the house has a first floor portion 10 and a second floor portion 20. In the first floor portion 10, a main indoor space includes an entrance 11, a hallway 12, a Japanese-style room 13, a living room 14, a dining room. 15, a kitchen 16, a washroom 17, a toilet 18, and a bathroom 19 are provided. The second floor portion 20 is provided with a staircase hall 21, a main bedroom 22, child rooms 23 and 24, and a toilet 25 as main indoor spaces.

A television T14 is arranged. In addition, toilet facilities G18 and G25 are installed in the toilet 18 of the first floor portion 10 and the toilet 25 of the second floor portion 20, respectively, and a washroom facility G17 is installed in the washroom 17 of the first floor portion 10.

  In the acoustic system, in each space of the first floor portion 10 and the second floor portion 20, wireless communication is performed with a portable device (portable communication device) carried by the user, and the position of the user at that time is confirmed. As a configuration for performing wireless communication with a portable device, as shown in FIG. 2, receiving devices J1, J2, J3, J4, J5, J6, J7, J8 are provided in the spaces 11 to 19 of the first floor portion 10, respectively. , J9, and receivers J11, J12, J13, J14, and J15 are provided in the spaces 21 to 25 of the second floor portion 20, respectively. Various information transmitted from the portable device 41 when the portable device 41 (see FIG. 3) enters the space where the receiving devices J1 to J9 and J11 to J15 are provided (or when the portable device 41 approaches the installation location). Can be received.

  Next, a schematic configuration of the acoustic system will be described with reference to FIG.

  As shown in FIG. 3, the receiving devices J <b> 1 to J <b> 9 and J <b> 11 to J <b> 15 of the first floor portion 10 and the second floor portion 20 are connected to the home server 31 via a network line 32. Similarly, the home server 31 is connected with a toilet equipment G18 on the first floor portion 10, a washroom equipment G17, and a toilet equipment G25 on the second floor via a network line 33. The audio devices A13, A14, A22, A23, A24 and the television T14 in the second floor portion 20 are connected via a network line 34. Furthermore, the home server 31 is connected to the Internet 35 and can acquire external information (such as weather information and content information) via the Internet 35.

  The home server 31 is a computer having a CPU, a memory, an input unit, a display unit, and the like. The home server 31 inputs ID information and biometric information described later from the portable device 41 through the receiving devices J1 to J9 and J11 to J15, and based on the input information, the audio devices A13, A14, A22, A23, The control of A24 is performed. On the other hand, the audio devices A13, A14, A22, A23, A24, and the television T14 transmit ON / OFF state signals to the home server 31.

  The portable device 41 includes a wireless communication unit 42. For example, wireless communication is possible between each of the receiving devices J1 to J9 and J11 to J15 with an area of about one room as a communication range (transmission / reception range). It has become. The portable device 41 includes a biological information measuring unit 43, and measures the user's biological information in real time. The biological information includes a pulse, body movement, skin temperature, skin potential, and the like. In the present embodiment, at least the pulse is measured. Furthermore, the portable device 41 is provided with a memory 44, and the memory 44 stores individual ID information (identification information) that is different for each owner (user). The ID information is at least a user who is authenticated by the control system, and is information that allows a plurality of users to be authenticated (for example, family members who live together) to be individually identified. Information (such as age information) and information such as sex are also included. The measured biological information is associated with ID information and the like, and is transmitted to the home server 31 via the receiving devices J1 to J9 and J11 to J15 from moment to moment. The ID information and the like are also registered in the home server 31, and the home server 31 can grasp which user the received biometric information belongs to.

  The portable device 41 is small and easily available, and can measure the biological information of the user. In this embodiment, the wristband type is worn on the user's wrist, but it may be realized as a pendant type, a ring type, or the like. In addition, even if it is not directly worn by the user, if it has a function capable of measuring biological information, the electronic key used in the smart key system is used as the portable device 41 or used daily. A mobile phone can be used as the mobile device 41, or an IC card having a communication function can be used as the mobile device 41. When the portable device 41 is a mobile phone, each of the receiving devices J1 to J9 and J11 to J15 receives communication radio waves and transmits information to the home server 31 that the user is on the phone.

  The in-toilet facilities G18 and G25 are installed in the toilet and measure the blood sugar level etc. from the user's excrement, and are installed in the soles and the toilet seat when the user is seated on the toilet seat. Sensors that measure weight, body fat, pulse, body temperature and bone density while in use. The washroom equipment G17 is a device that measures the user's weight, body fat, pulse, body temperature, and bone density, and can employ a weight scale with a body fat scale, a sensor installed on the floor, and the like. The biological information measured by the toilet facilities G18 and G25 and the washroom facility G17 is transmitted to the home server 31 at the timing when it is obtained.

  The biometric information transmitted to the home server 31 from the portable device 41, the in-toilet facilities G18 and G25, and the washroom equipment G17 is accumulated and stored in the home server 31. The biometric information is transmitted from the portable device 41 every moment and is transmitted from the toilet facilities G19 and G25 and the washroom facility G17, but the home server 31 has a calendar function and a clock function. It is stored in the biological information history database in association with the date, day of the week, time, and weather at each time point when the biological information is transmitted.

  The home server 31 stores an analysis program for physical condition, mental state, and exercise state, and thereby analyzes the physical condition, mental state, and exercise state of each user. The analysis of physical condition compares the current pulse, body movement, skin temperature, skin potential, etc., and the weight, body fat, pulse, body temperature, bone density, etc. stored in the biological information history database with reference values, Analyzes whether “normal”, “fatigue” or “disease”. The mental state is analyzed based on the current pulse rate, skin temperature, skin potential, etc., whether it is a “relaxed state”, a “tension state”, or a “sleep state”. Further, whether the exercise state is “active state” or “still state” is analyzed based on the current pulse, body movement, skin temperature, and the like.

  The home server 31 stores a content database. In the present embodiment, “sound content” or “content” is expressed in units of one track (one song). As illustrated in FIG. 4, the content database stores content names (song titles) and artists that each user likes for each user (for each ID information). The content name (song name) and artist are registered by each user directly entering the home server 31. In the present embodiment, “content” includes all contents including sound, such as music, natural sounds, and artificially created sounds. The home server 31 stores a content analysis program, analyzes the user's preference based on the content directly input by the user, searches the Internet 35 for content that the user is likely to like, and recommends the content. You may recommend based on attributes, such as a user's age and sex. The user can select and input the content to be added to the list from the recommended content. Furthermore, when the content determined to have a particularly high audience effect for a plurality of users is not included in the list, the content is automatically added to the list.

  Furthermore, the home server 31 analyzes the information such as the frequency, volume level, rhythm, tempo, etc. of the content, the repetitive pattern of the chord progression with the passage of the performance time of the content (song), and the excitement section by the content analysis program. And extract the features of the content. Based on the characteristics of each content, the physical condition (“normal state”, “fatigue state”, “disease state”), listening purpose (“relaxing”, “concentrating”, “refreshing”) , "For sleep"), season, time zone, and weather. Or you may acquire the information of the listening purpose to adapt, a season, etc. with reference to the content information provided on the internet 35. FIG. The analyzed or acquired information is stored in association with each content (song) as shown in FIG.

  Note that even if content that is considered to be adapted based on the information analyzed or obtained as described above is played, the specific range is cut or the rhythm / tempo is changed by the user, as will be described later. May be adjusted or may be changed to other contents. Even in such cases, the content database contains the date (date / day / day / time) when the content was actually played, and the physical condition, mental state, exercise state, and weather of the user at that time. Is stored in association with the adjustment content). The content analysis program also has a learning function, which captures information at each point in time when the content was actually played back, re-executes the analysis, customizes information on conditions that each content adapts, and rewrites the content database . Thereby, the content database reflecting the change (preference) by the user is constructed.

  Furthermore, the home server 31 acquires biometric information every time content reproduction ends, and determines whether there is an effect corresponding to the purpose of listening to the content. For example, if the purpose of listening is “for relaxation”, the mental state is analyzed when the playback of the content is completed, and if the analysis result is “relaxed”, it is determined that there is an effect. ", It is determined that there was no effect. Then, the contents analysis is executed by taking in the information on the presence / absence of the effect, and the contents database is rewritten by customizing the information on each contents.

  In addition, content that is highly effective for a plurality of users is considered to be effective when there are a plurality of users in one room or when a user without ID information registration appears. Therefore, information indicating that the effect is high for a plurality of users is stored in association with the content. Here, when the effect is particularly high for a user of a specific age group, sex, etc., information to that effect is stored in association with the content stored for the user corresponding to that age group, gender, etc. . As described above, if the highly effective content is not included in the user list, it is added to the user list. On the other hand, for content that is not effective for a specific age group, sex, etc., information to that effect is stored in association with the content stored for the user corresponding to that age group, sex, etc. Content analysis is re-executed based on the information stored in this manner, and a content database reflecting actual effects is constructed.

  The home server 31 stores a priority database. The priority is information related to the priority of which content is to be reproduced when there are a plurality of users (for example, a family living together) in one room where the audio device is arranged. In this embodiment, priority is given in the order of “disease state” → “fatigue state” → “normal state” based on the physical condition of each user. Further, when a plurality of users have the same physical condition, a user to be prioritized is determined according to a priority order determined in advance by the user (for example, “infant → elderly → adult”).

  The audio devices A13, A14, A22, A23, A24 automatically select and reproduce the content based on the control signal transmitted from the home server 31. The audio devices A13, A14, A22, A23, and A24 each have an input button, and an input operation by the user is performed. The input operation by the user is performed, for example, when a specific sound range is cut for the content being reproduced, when the rhythm / tempo is to be changed, or when the content being reproduced is to be changed to another content. The input operation can also be performed by a remote controller (not shown).

  In the acoustic system having the above configuration, when the user is present in the house, the portable device 41 that has entered the reception area of the request signal periodically transmitted from the receiving devices J1 to J9 and J11 to J15 is the request signal. In response, ID information is transmitted. The home server 31 inputs the ID information transmitted from the portable device 41 through the receiving devices J1 to J9 and J11 to J15, and the devices of the audio devices A13, A14, A22, A23, and A24 based on the input information. Implement control.

  Hereinafter, the audio device control processing executed by the acoustic system will be described with reference to the flowchart of FIG. The flowchart in FIG. 5 illustrates a process executed by the home server 31 for an audio device arranged in a room. This process is repeatedly executed at regular intervals (for example, every 1 second or every 10 seconds).

  First, in step S11, it is determined whether or not the user exists in the room. That is, it is determined whether or not the receiving device installed in the room has received the ID information transmitted from the portable device 41. If it is determined that there is no user (NO in step S11), the process ends and the process returns to the beginning.

  On the other hand, if it is determined in step S11 that there is a user (YES in step S11), the process proceeds to step S12, and it is determined whether other sound generating devices in the same room are in the ON state. The sound generating device here is a device such as a television T14 or a mobile phone that is considered to be undesirable if the sound of the audio device interferes. If the television T14 is in the ON state, the information is transmitted to the home server 31, and if the mobile phone is communicating, the information is transmitted to the home server 31, so that the determination in step S12 can be performed. If any of the sound generating devices is determined to be in the ON state (YES in step S12), the process proceeds to step S18 to determine whether or not the content is being reproduced on the audio device to be controlled. If the audio device is in an OFF state and is not being played back (NO in step S18), the process is terminated and the process returns to the beginning. On the other hand, if playback is in progress (YES in step S18), the content is stopped in step S19 and the process returns to the beginning. Thereby, it is avoided that the content reproduction of the audio device becomes an obstacle during the operation of other audio generating devices.

  On the other hand, if it is determined in step S12 that the other sound generating device is not in the ON state (NO in step S12), the process proceeds to step S13. In step S13, user ID information and biometric information are acquired, and date / time information and weather information are acquired. The ID information is acquired from the portable device 41, and the biological information is transmitted from the portable device 41 and stored in the biological information history database (the toilet facilities G18 and G25, and the bathroom) Acquired from the equipment G17). Date / time information is acquired from a calendar function / clock function, and weather information is acquired via the Internet 35.

  Next, in step S14, it is determined whether or not the content is being reproduced on the audio device to be controlled. If the audio device is not being played back in the OFF state (NO in step S14), the process proceeds to step S15 to determine whether or not the user is sleeping based on the user's biological information. If there is a plurality of users (even one of them) is sleeping (YES in step S15), the process ends as it is, but if not sleeping (NO in step S15), the process proceeds to step S16. To do.

In step S16, content is selected by the following procedure;
(i) Analyzing the physical condition, mental state, and movement state of the user at the present time,
(ii) If there are multiple users in the room, refer to the priority database and select the preferred user.
(iii) Referring to the content database, from the user's (priority) content list, select content that matches the current physical condition, mental state, exercise state, season, time zone, and weather. Note that the purpose of listening to the content that the user may desire (“for relaxation”, “for concentration”, “for refresh”, “for sleep”) can be estimated as follows, for example:
・ If the mental state is "Relaxed" and the exercise state is "Active", "Concentrated" content,
・ If the mental state is "Relaxed" and the exercise state is "Still", "Relaxing" content,
・ If the mental state is “Tension” and the exercise state is “Active”, “Refresh” content,
・ If the mental state is “tension” and the exercise state is “still”, “relaxing” content,
• “Sleep” content if it is within 1 hour before the user's normal sleep time.
When the content is selected in this way, the reproduction of the content is started in step S17.

  On the other hand, if the content is being played back by the audio device to be controlled in step S14 (YES in step S14), the process proceeds to step S20, and it is determined whether the user is sleeping. If there is a plurality of users (even one of them) is sleeping (YES in step S20), the content is stopped in step S19, but if not sleeping (NO in step S20), step S21 Migrate to

In step S21, it is determined whether or not a content change condition is satisfied. If any of the following cases (a) to (d) occurs as compared with the point in time when the content being played back is selected, the content change condition is satisfied;
(a) When the user performs a content change operation using the input button of the audio device,
(b) When the priority user has changed and the content being played is not adapted and is just before the end of the content,
(c) When the user's physical condition (priority) deteriorates and the content being played is not adapted and is just before the end of the content,
(d) When the user's mental state and exercise state change (priority), the content being reproduced is not adapted, and immediately before the end of the content.
Note that (b) is considered to occur, for example, when there is an increase or decrease in the number of users, or when there is no change in the number of users but there is a change in physical condition.

  If any of the above cases (a) to (d) occurs and the content change condition is satisfied (YES in step S21), the process proceeds to step S22, and a new content is selected. In the case of (a), the content changed by the user is selected, and in the cases of (b), (c), and (d), the contents to be respectively adapted from the content database are selected by the same method as in step S16. When the content is selected in this way, reproduction of the content changed in step S17 is started.

  On the other hand, when the content change condition is not satisfied in step S21 (NO in step S21), the content being reproduced is continued as it is (step S23).

  As described above, according to the present acoustic system, content suitable for the user's physical condition / mental state / exercise state, season, time zone, weather, etc. is automatically selected and reproduced, so that the user's health is objectively improved. Sound content suitable for the state and suitable for TPO is reproduced without bothering the user. Further, when a plurality of users are present in one room, they are selected in accordance with a predetermined priority order, so that objectivity is maintained for selection of priority users. Further, even when the automatically selected content is adjusted / changed by the user himself / herself, the content database reflecting the user's preference is constructed in order to rewrite the content database by taking in the information. In addition, every time content playback ends, it is determined whether or not there is an effect according to the purpose of listening to the content, and the content database reflecting the actual effect is rewritten to incorporate the information on the presence or absence of the effect and rewrite the content database. It will be built.

  Note that the sleep determinations in steps S15 and S20 are executed only when controlling the audio devices 22A, 23A, and 24A disposed in the main bedroom 22 and the child rooms 23 and 24, and are disposed in other indoor spaces. The audio devices A13 and A14 may not be executed.

  Moreover, it is good also as a porous structure which consists of the base material and finishing material which each have many holes for the face material of the ceiling, the wall, the floor, and the fitting of the indoor space where the audio devices A13, A14, A22, A23, and A24 are arranged. . Then, an actuator is attached to the base material and / or the finish material so that the actuator can be translated in the flat surface direction of the face material, and the position of the hole group of the base material and the position of the hole group of the finish material are matched or shifted. As a result, for example, when a high volume content is reproduced, the position of the hole group of the base material and the position of the hole group of the finishing material can be matched to penetrate the hole, and the sound reflectance can be lowered. On the other hand, when content with a small volume is reproduced, the position of the hole group of the base material and the position of the hole group of the finishing material can be shifted to close the hole and increase the sound reflectance.

(Other embodiment of content reproduction apparatus)
In the above embodiment, the control processing is performed on the audio devices A13, A14, A22, A23, and A24 arranged in the indoor space of the house. However, the home server 31 may be communicable with a mobile phone / vehicle-mounted device or the like, and the control process may be performed for the mobile phone / vehicle-mounted device or the like. When the control process is performed on the in-vehicle device, content that is not suitable for driving (such as “for sleep”) is excluded from the selection candidates.

  In the above embodiment, information related to content actually played by the audio device A13 or the like is accumulated in the content database, and information related to each content is customized by the learning function. However, content reproduced by a mobile phone, an in-vehicle device or the like may be stored in the content database. As a result, the accumulated data increases and it can be customized to more accurate information.

(Other embodiments of content selection)
In the above embodiment, the content list stored in the content database is created when each user directly inputs the content name to the home server 31. However, it may be necessary to reproduce the content for a user who has not registered ID information, such as a visitor. For such a user, whether or not there is an effect according to the purpose of listening to the content is not determined, but it is possible to select content that is highly effective for a plurality of users. Alternatively, content can be selected from the content list of another user who seems to have the closest preference based on the age of the user. Furthermore, even when the priority order is not determined in advance, it is considered that there is little difficulty for any user if content that has been highly effective for a plurality of users is selected.

(Other embodiment of biometric information acquisition)
In the above embodiment, biological information such as pulse, body movement, skin temperature, skin potential, body weight, body fat, and the like has been acquired by the portable device 41, toilet facilities G18 and G25, and the bathroom interior device G17. It is not limited. For example, acquiring biological information by other methods, such as acquiring brain waves with the headgear provided in the chair, acquiring skin temperature with a thermo camera, or detecting pressure fluctuations built into the air mattress. You can also.
