For example, a plurality of types of biological information such as body temperature data, pulse data, and respiratory rate from a body temperature sensor, a pulse sensor, and a respiration sensor attached to a human body are acquired. FIG. 1 shows two cases. The acquired biometric information is stored in a memory in the biometric information storage unit 13. The stored biological information is supplied from the biological information storage unit 13 to the chord composition unit 14. The chord constructing unit 14 has a function of converting the input biological information into chord information. The chord information output from the chord constructing unit 14 is supplied to the chord output unit 15, and the chord output unit 15 generates and outputs a chord sound signal. In the present embodiment, the chord information takes the form of a set of a plurality of pitch information.

  FIG. 2A is a block diagram illustrating an embodiment of the chord constructing unit 14. In FIG. 2, the chord constructing unit 14 includes a plurality of biological information pitch conversion units 21 and 22, and converts biological information from the biological information storage unit 13 into pitch information. The outputs of the biological information pitch conversion units 21 and 22 are supplied to the tone synthesis units 27 and 28 of the chord output unit 15, respectively. The musical tone synthesis units 27 and 28 generate and output musical instrument sound signals corresponding to the pitch of the sound indicated by the received pitch information. The generated instrument sound signal becomes sound through a speaker.

  The biological information pitch conversion unit 21 converts biological information into pitch information. That is, the biological information pitch conversion unit 21 converts the voltage or digital magnitude data of the biological information into sound pitch (frequency) data. The biological information pitch conversion unit 21 normally includes a conversion table recorded in a ROM, RAM, or the like. The conversion table is a correspondence table between biometric information values and frequency values. For example, the biological information pitch conversion unit 21 has a conversion characteristic that increases the pitch of the sound as the body temperature increases, and the biological information pitch conversion unit 22 performs the conversion that increases the pitch of the sound as the pulse rate increases. Characteristic. Note that the biological information pitch conversion unit 21 has a conversion characteristic that increases the pitch of the sound as the body temperature is higher, and a normal pitch, and the biological information pitch conversion unit 22 The faster the pulse, the higher the pitch of the sound, and in normal wishes, the pitch of the sound may be used.

  (Embodiment 2)

  Next, a sound output device for living body information capable of monitoring more states of the living body will be described with reference to FIG. In FIG. 2B, the chord constructing unit 24 includes a chord information converting unit 26. The biological information supplied from the biological information storage unit 13 is input to the chord information conversion unit 26 and converted into chord information specifying a chord, and the chord information is supplied to the chord output unit 25. The chord output unit 15 generates and outputs the instructed chord. The chord information may be in the form of a chord that identifies one of a plurality of chords to be described later.

  The chord information conversion unit 26 classifies the sizes of the plurality of input biological information in the multidimensional space and associates them with the plurality of chords. First, the types of chords will be described. There are many types of chords, as is known from harmony studies. Here, a triad composed of sounds of three different pitches is taken up. A triad is a chord having a structure in which a sound having a pitch of 3rd degree (referred to as 3rd note) and a sound having a pitch of 5th degree (referred to as 5th note) are superimposed on the root tone. The three chords include major triads, minor triads, increased triads, and reduced triads. These are determined by the interval between the root tone and the third tone and the interval between the third tone and the fifth tone, that is, whether each pitch is a major third or minor third. Chosan chords are bright and calm. The short triad is lonely but calm. Masusan chords are frustrating. The reduced triad is uneasy. FIG. 2C shows an example in which these four types of triads are used for monitoring. In FIG. 2C, a two-dimensional region based on body temperature and pulse is divided into four. (A) is a normal region. (B) is a region requiring attention that is slightly out of normal. (C) is a dangerous area with low body temperature and slow pulse. (D) is a warning area with high body temperature and fast pulse. The long triad is assigned to (a), the short triad is assigned to (b), the increased triad is assigned to (c), and the reduced triad is assigned to (d).

  In order to realize the characteristics as shown in FIG. 2C, a database system that outputs body temperature information and pulse information as entries and outputs four types of chord information may be provided in the chord information conversion unit 26. The chord composition unit 24 outputs information on any of the long triad, short triad, increased triad, and subtractive chord to the chord output unit 25. Generates and outputs one of three chords, increased triads, and reduced triads. In this way, the state of the living body can be grasped instantaneously from the sound of chords.

  If there are more than 3 types of biological information, such as when there are more than 4 types of statuses to be distinguished in monitoring, in addition to the above 3 chords, a 4 chord composed of sounds of 4 different pitches (Siwaon) may be used.

  A four chord is a chord composed of four different pitches, and is a chord in which the fourth note of the third or third pitch is added to the fifth note of the third chord. is there. The four chords are composed of seven genus chords and six sub-seven chords, for a total of seven types. Each of the four chords has a different sound than the four of the three chords. It has features that are different from the three chords, such as those that make you expect the next chord, those that are very tense, and those that have a sweet feeling. Those features may be assigned corresponding to the state of the living body.

  When using four chords, the chord output unit 25 may be configured to generate a chord composed of four constituent sounds.

  There are nine chords, eleven chords, thirteen chords, etc., which have a larger number of chords, and these may be used.

  In the case of biological information indicating that the state of the living body is extremely poor, a chord having a greater disagreement than the above chords may be used. If the three chords and the four chords are composed of two short notes, that is, two semitones, an unpleasant sounding chord can be used.

  In the case where there are three types of biological information, four regions corresponding to triads may be divided and set in the three-dimensional space in which the third biological information is added to FIG. Even when there are four or more types of biological information, a multidimensional space may be set, and regions as many as the number of chords by triads or four chords may be provided in the space.

  As mentioned above, according to this Embodiment, if a user uses said sound output apparatus, for example every day, the change of a physical condition and the change of a health degree can be grasped | ascertained in a short time.

  (Embodiment 3)

  The chord information conversion unit 26 may perform a polynomial calculation using the values of a plurality of biological information as variables, and select a chord type from the calculation result. A chord frequency may be given to each chord according to the degree of harmony of the chords, and chord information having the closest score to the numerical value of the polynomial calculation result may be selected and output.

  In addition to the polynomial, a logical expression or another arithmetic expression may be used, and a chord may be selected depending on the calculation result. For example, it may include a form of a functional expression using biometric information as a variable, and a formula that combines the functional expressions of each piece of biometric information with a product sum.
