Description

【Technical Field】 【0001】 The present disclosure relates to a control system, earphones, and a control method. 【Background Art】 【0002】 Patent Document 1 discloses earphones having a leakage control function that can switch between a leaking state and a non-leaking state in order to adapt to different listening environments. The earphones are shaped and configured to be disposed so as to substantially cover the ear canal. The earphones have a housing that houses a speaker element that emits sound into the ear canal, and the housing has a channel that extends from an inner end facing the ear canal side to an outer end facing the peripheral side. The earphones include a closing means that can switch between a closed state in which the channel is substantially closed and an open state in which the channel allows sound from the surroundings to pass through. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Translation of PCT International Publication No. 2009-525629 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 Conventionally, earphones are inserted into each of the user's left and right ears to seal the user's ear canals, so that the user can listen to the sound output in a state where ambient noise is blocked. However, when the user speaks while wearing the earphones (for example, when making a phone call), the user may feel that their own voice is trapped and it may be difficult to speak. 【0005】 Patent Document 1 describes how earphones change between a sealed and unsealed state of the user's ear canal by controlling channels in the housing. The earphones disclosed in Patent Document 1 seal the user's ears by closing the channels when playing music, and open the channels to leave the user's ears open when making a phone call. 【0006】 On the other hand, even when playing music with earphones, sealing the ear canal with the earphones can cause vibrations from the user's movements to resonate within the body, sometimes causing discomfort. These vibrations include the user's breathing sounds while moving. Therefore, it was necessary to reduce the resonance of vibrations from the user's movements within the user's body when wearing earphones. 【0007】 This disclosure was devised in light of the conventional circumstances described above, and aims to control the sealed or open state of the earphones worn in the ear according to the user's movement, thereby suppressing discomfort. [Means for solving the problem] 【0008】 This disclosure comprises an earphone worn in the left and right ears of the user, each having a housing with an internal space and a path that allows ventilation from one end facing the user's ear canal to the other facing the ambient environment, and a valve housed inside the housing that can close off a portion of the path, and a wireless terminal carried by the user, wherein the wireless terminal is The device has a display unit, which displays a screen for setting the opening and closing of the on / off valve related to the user's movement, and the screen includes a field for setting a first range in which the user's movement speed is equal to or greater than a first speed and less than or equal to a second speed greater than the first speed, and a field for setting a second range in which the movement speed is equal to or greater than a third speed greater than the second speed. before Record transfer Dynamic speed The set first range or the second If it is determined that the speed is within the range, the earphone will receive the aforementioned speed signal.

When it is determined that the moving speed is within the predetermined range, a signal is transmitted to the earphone indicating that the moving speed is within the predetermined range, and the earphone controls the on / off valve based on the signal obtained from the wireless terminal. 【0009】 Furthermore, this disclosure relates to an earphone that is communicatively connected to a wireless terminal, comprising: a housing having a space inside and a path that allows ventilation from one end facing the user's ear canal to the other end facing the surrounding environment; and an on / off valve housed inside the housing that can close a part of the path, wherein the user's movement speed can be detected from the wireless terminal. A first range in which the moving speed is greater than or equal to a first speed set by the user and less than or equal to a second speed greater than the first speed, or a second range in which the moving speed is greater than or equal to a third speed greater than or equal to the second speed. The present invention provides earphones that, upon receiving a signal indicating that the speed is within a certain range, control the on / off valve based on the said signal. 【0010】 Furthermore, this disclosure relates to a method for controlling an earphone, which is worn on the left and right ears of the user, and a wireless terminal, the wireless terminal having a housing that has a space inside and a path that allows ventilation from one end on the user's ear canal side to the other end on the ambient environment side, and an on / off valve housed inside the housing that can close a part of the path but , The system displays a screen for setting the opening and closing of the on / off valve related to the user's movement, and the screen includes a field for setting a first range in which the user's movement speed is equal to or greater than a first speed and less than or equal to a second speed greater than the first speed, and a field for setting a second range in which the movement speed is equal to or greater than a third speed greater than or equal to the second speed. before Record transfer Dynamic speed The set first range or the second If it is determined that the speed is within the range, the earphone will receive the aforementioned speed signal.

However, detailed descriptions that are more than necessary may be omitted. For example, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following descriptions unnecessarily redundant and to facilitate the understanding of those skilled in the art. Note that the attached drawings and the following descriptions are provided to enable those skilled in the art to fully understand the present disclosure, and it is not intended to limit the subject matter described in the claims thereby. 【0015】 First, referring to FIGS. 1 and 2, the hardware configuration of the earphone will be described. FIG. 1 is a figure showing the front view of the earphone. FIG. 2 is a figure showing the rear view of the earphone. 【0016】 For the sake of explanation, as shown in Figure 1, the X and Y axes are defined along a plane parallel to the surface of the touch sensor TCL of the earphone 1L, and the axis perpendicular to the surface of the touch sensor TCL is defined as the Z axis. When the microphone MC1L side of the touch sensor TCL is considered the upper end of the earphone 1L, and the microphone MC2L on the opposite side of the touch sensor TCL is considered the lower end, the axis extending from the lower end to the upper end is defined as the X axis. The axis perpendicular to the X and Z axes is defined as the Y axis. In this embodiment, the orientation of the earphone 1L shown in Figure 1 is defined as the front view. These directional expressions are used for the sake of explanation and are not intended to limit the orientation of the structure during actual use. The same applies to the other drawings. 【0017】 Furthermore, in this embodiment, the left earphone 1L and the right earphone 1R are identical in configuration. Identical components are indicated by adding "L" to the end of the left earphone 1L's name and "R" to the end of the right earphone 1R's name. In the following description, only the left earphone 1L will be described, and the description of the other earphone, the right earphone 1R, will be omitted. 【0018】 Earphone 1 is an earphone 1L, 1R that is worn on the user's left and right ears, respectively, and has multiple interchangeable eartips of different sizes attached to one end of each earphone. Earphone 1 may consist of two independently operating earphones (i.e., earphone 1L and earphone 1R), which are composed of earphone 1L worn on the user's left ear and earphone 1R worn on the user's right ear. In this case, earphone 1L and earphone 1R can communicate wirelessly (for example, via short-range wireless communication such as Bluetooth®). Alternatively, earphone 1 may be configured as a pair of earphones in which earphone 1L and earphone 1R are connected by a wire (in other words, a cable such as a wire). 【0019】 As shown in Figure 1, the earphone 1L is an in-ear acoustic device worn in the user's ear and receives sound data (e.g., music data) transmitted wirelessly (e.g., via short-range wireless communication such as Bluetooth®) from an external device such as a smartphone or portable music player owned by the user. The earphone 1L acoustically outputs an audio signal based on the received sound data. When not in use, the earphone 1L is placed on a cradle (not shown), which is a charging case. If the battery B1L (Figure 3) built into the earphone 1L is not fully charged, the earphone 1L is placed on a designated spot on the cradle, and the battery B1L built into the earphone is charged based on the power supplied from the cradle. 【0020】 The earphone 1L has a housing HOL as a structural component. The housing HOL is made of a composite material such as synthetic resin, metal, and ceramic, and a storage space is formed inside it in which various components constituting the earphone 1L are housed. The housing HOL is also provided with a mounting cylindrical part FCL1 (see Figures 3 and 4) that communicates with the storage space. This mounting cylindrical part FCL1 is provided on one end of the housing HOL opposite to the touch sensor TCL, which will be described later. 【0021】 The earphone 1L has an earpiece IPL that attaches to the main body of the earphone 1L. For example, the earphone 1L is held in the user's ear by being inserted into the ear canal by the earpiece IPL, and this held state is considered the state in which the earphone 1L is in use. 【0022】 The IPL earpiece is made of a flexible material such as silicone and is injection molded, having an inner cylinder (not shown) and an outer cylinder (not shown). The IPL earpiece is inserted and fixed into the mounting cylinder FCL1 of the housing HOL by its inner cylinder, and is also provided on the mounting cylinder FCL1 of the housing HOL in a replaceable (detachable) manner. The IPL earpiece is fitted into the user's ear canal by its outer cylinder and elastically deforms according to the shape of the ear canal into which it is fitted. This elastic deformation holds the IPL earpiece in the user's ear canal. The IPL earpiece comes in several different sizes. One of the multiple different sizes of the IPL earpiece is attached to the earphone 1L and worn in the user's left ear. 【0023】 As an example of an input unit, the touch sensor TCL is provided on the opposite end of the housing HOL from the end where the earpiece IPL is located, as shown in Figure 1. The touch sensor TCL is a sensor element having a touch sensor function that detects user input operations (e.g., touch operations). The sensor element is, for example, an electrode of a capacitive touch sensor. The touch sensor TCL may be formed as, for example, a circular surface, or as, for example, an elliptical surface. Alternatively, the touch sensor TCL may be formed as a rectangular surface. 【0024】 Furthermore, examples of touch operations on the touch sensor TCL by the user's finger, etc., include the following: When a short touch operation is performed on the earphone 1L, it may instruct an external device to play, stop, skip tracks, or skip tracks back. When a long touch operation (so-called long press) is performed on the earphone 1L, it may perform pairing operations for wireless communication such as Bluetooth® with an external device such as a smartphone. In addition, when a finger is traced over the surface of the touch sensor TCL (so-called swipe operation), the earphone 1L may adjust the volume of the music being played. 【0025】 The opening 60L is a hole formed in the housing HOL that leads to a ventilation path from one end facing the user's ear canal to the other end facing the surrounding environment. Detailed cross-sectional examples of the structure of the opening 60L will be described later with reference to Figures 3 and 4. 【0026】 Earphone 1L has multiple microphones (microphone MC1L, microphone MC2L, and microphone MC3L) as electrical and electronic components. These multiple microphones are housed in a storage space (not shown) within the housing HOL. 【0027】 As shown in Figure 1, the microphone MC1L is positioned so as to be exposed on or near the surface of the housing HOL, and is configured to pick up ambient sounds from outside the earphone 1L. In other words, the microphone MC1L can detect the user's ambient sounds when the earphone 1L is worn in the user's ear. The microphone MC1L converts the external ambient sounds into electrical signals (sound signals) and sends them to the sound signal input / output control unit S1L. 【0028】 As shown in Figure 1, the microphone MC2L is positioned so as to be exposed on or near the surface of the housing HOL, and is configured to pick up audio signals based on the user's speech while wearing the earphone 1L. Therefore, the earphone 1L can communicate with the user's mobile phone device, such as the smartphone F1, enabling so-called hands-free calling. The microphone MC2L is composed of a microphone device capable of picking up (i.e., detecting audio signals) the sound generated based on the user's speech. The microphone MC2L picks up the sound generated based on the user's speech, converts it into an electrical signal, and sends it to the sound signal input / output control unit S1L. The microphone MC2L is positioned so that when the earphone 1L is inserted into the user's left ear, the extension direction of the earphone 1L faces the user's mouth (see Figure 1), and is located below the touch sensor TCL (i.e., in the -X direction). The sound uttered by the user is picked up by the microphone MC2L and converted into an electrical signal, and the presence or absence of user speech can be detected by the microphone MC2L based on the magnitude of this electrical signal. 【0029】 As shown in Figure 2, the microphone MC3L is positioned in the plane near the mounting cylindrical portion FCL1 of the housing HOL, and is positioned as close as possible to the external auditory canal of the left ear when the earphone 1L is inserted into the user's left ear. The microphone MC3L converts the sound leaking from between the user's left ear and the earpiece IPL when the earphone 1L is worn in the user's left ear into an electrical signal (sound signal) and sends it to the sound signal input / output control unit S1L. 【0030】 As shown in Figure 2, the speaker SP1L is positioned within the mounting cylindrical portion FCL1 of the housing HOL. The speaker SP1L is an electronic component that acoustically outputs sound data (e.g., music data) transmitted wirelessly from an external device. Inside the housing HOL, the front surface of the speaker SP1L (in other words, the sound emission surface of the acoustically output sound) is directed toward the mounting cylindrical portion FCL1 of the housing HOL, which is covered by the earpiece IPL. As a result, the music data acoustically output from the speaker SP1L is transmitted from the user's ear canal (e.g., the outer ear) to the external auditory canal of the outer ear and then to the eardrum of the middle ear, allowing the user to hear the music data. 【0031】 The wear sensor SEL consists of a device that detects whether or not the earphone 1L is worn on the user's left ear, and can be configured using, for example, an infrared sensor or an electrostatic sensor. In the case of an infrared sensor, if the earphone 1L is worn on the user's left ear, the wear sensor SEL can detect that it is worn on the user's left ear by receiving infrared light reflected from the infrared light emitted from the wear sensor SEL within the left ear. If the earphone 1L is not worn on the user's left ear, the wear sensor SEL can detect that it is not worn on the user's left ear by not receiving infrared light that is not reflected from the infrared light emitted from the wear sensor SEL. On the other hand, in the case of an electrostatic sensor, if the earphone 1L is worn on the user's left ear, the wear sensor SEL can detect that it is worn on the user's left ear by determining that the change in capacitance value corresponding to the distance to the inside of the user's left ear is greater than a threshold held by the wear sensor SEL. If the earphone 1L is not worn on the user's left ear, the wear sensor SEL can detect that it is not worn on the user's left ear by determining that the change in capacitance value is less than a threshold held by the wear sensor SEL. The wear sensor SEL is positioned to face the ear canal when the earphone 1L is inserted into the user's left ear, and is located on the back side of the touch sensor TCL. 【0032】 Next, the open and closed states of the on / off valve will be explained with reference to Figures 3 and 4. Figure 3 shows the on / off valve in the closed state. Figure 4 shows the on / off valve in the open state. Figures 3 and 4 are diagrams of earphone 1R, but earphone 1L has a similar structure and will not be explained here. Also, the eartips IPL and IPR (see Figures 1 and 2) are not shown in Figures 3 and 4. 【0033】 The cross-sectional views shown in Figures 3 and 4 are cross-sectional views AA of earphone 1R shown in Figure 1. 【0034】 The on / off valve 70R is a device with a movable mechanism that controls the air passing through the path 71. The on / off valve 70R switches between opening and sealing the path 71, which releases sound remaining inside the housing HOR to the outside of the housing HOR. The sound remaining inside the housing HOR is, for example, the reverberation of sound output from the driver SP1RDr, or the transmitted sound acoustically transmitted through the user's body to the vicinity of the right ear by the user's speech. These sounds cause discomfort or difficulty in hearing external sounds when the user speaks while wearing the earphone 1R. The operation of the on / off valve 70R (specifically, opening and closing) is controlled by the earphone control unit S2R. The valve may be, for example, a gate valve as shown in Figure 3, or a globe valve, needle valve, ball valve, or butterfly valve. 【0035】 The on / off valve 70R moves in the direction DR1 based on a signal (control signal) from the earphone control unit S2L. By moving in the direction DR1 and contacting the wall surface 72, the on / off valve 70R can close the path 71 and create a tight seal. The state in Figure 3 where the on / off valve 70 is in contact with the wall surface 72 and closing the path 71 is referred to as the "closed state". When the user wears the earphone 1R in their right ear and the on / off valve 70 is in the closed state, the path 71 is blocked by the on / off valve 70R, so the user's ear is sealed. 【0036】 The state in which the on / off valve 70R shown in Figure 4 is separated from the wall surface 72 by a certain distance and the path 71 is open is referred to as the "open state". The path 71 is opened when the on / off valve 70R moves in the direction DR1 and separates from the wall surface 72. When the user wears the earphone 1R in their right ear and the on / off valve 70R is in the open state, the path 71 is not blocked by the on / off valve 70R and is connected to the surrounding environment on the touch sensor TCR side, so the user's ear is not sealed. In this state, any sound remaining inside the housing HOR is released to the outside of the housing HOR via the path 71, and it is expected that the user will not feel any discomfort or difficulty hearing external sounds when speaking while wearing the earphone 1R. 【0037】 Next, the block diagram of the earphones will be described with reference to Figure 5. Figure 5 is a diagram showing the block diagram of the earphones according to this embodiment. Figure 5 is a block diagram of the left and right pair of earphones 1L and 1R shown in Figures 1 and 2. In the following, the configuration of earphone 1L will be described, but the configuration of earphone 1R is the same as that of earphone 1L. Therefore, similarly in Figure 5, the description of earphone 1R will be omitted. 【0038】 The earphone control system 100 includes earphones 1L, 1R, and smartphone F1. 【0039】 A touch sensor TCL, which is an example of an input unit, is connected to the earphone control unit S2L ​​for communication. The touch sensor TCL outputs signals related to touch operations performed by the user to the earphone control unit S2L. 【0040】 The wear sensor SEL is connected to the earphone control unit S2L ​​for communication and outputs a signal to the earphone control unit S2L ​​indicating whether or not the user's ear and the earphone 1L are in contact. 【0041】 The power monitoring unit 13L is configured using, for example, a semiconductor chip. The power monitoring unit 13L has a battery B1L and measures the remaining charge of battery B1L. Battery B1L is, for example, a lithium-ion battery. The power monitoring unit 13L outputs information regarding the measured remaining charge of battery B1L to the earphone control unit S2L. 【0042】 The audio signal input / output control unit S1L is configured using a processor such as a CPU (Central Processing Unit), MPU (Micro Processing Unit), or DSP (Digital Signal Processor). The audio signal input / output control unit S1L is connected to the earphone control unit S2L ​​for communication and exchanges audio signals as digital signals converted to digital format using the PCM (Pulse Code Modulation) method. The audio signal input / output control unit S1L adjusts the volume level of the digital signal related to the audio signal acquired from the smartphone F1 and outputs it to the speaker SP1L. 【0043】 The audio signal input / output control unit S1L is connected to microphones MC1L, MC2L, and MC3L, and receives audio signals picked up by each microphone. The audio signal input / output control unit S1L may be capable of processing the audio signals input from each microphone, such as amplifying them or converting them from analog signals to digital signals. The audio signal input / output control unit S1L transmits the audio signal data input from each microphone to the earphone control unit S2L. 【0044】 As an example of a control unit, the earphone control unit S2L ​​is configured using a processor such as a CPU, MPU, or DSP, and is communicatively connected to the sound signal input / output control unit S1L, ROM 11L, RAM 12L, power monitoring unit 13L, on / off valve 70L, and wireless communication unit 14L, and exchanges sound signals as digital signals converted to digital format using the PCM method. The earphone control unit S2L ​​functions as a controller that oversees the overall operation of the earphone 1L, and performs control processing to coordinate the operation of each part of the earphone 1L, data input / output processing between each part of the earphone 1L, data calculation processing, and data storage processing. 【0045】 The audio signal input / output control unit S1L and the earphone control unit S2L ​​implement their respective functions using programs and data stored in the ROM (Read Only Memory) 11L. The audio signal input / output control unit S1L and the earphone control unit S2L ​​may use the RAM (Random Access Memory) 12L during operation to temporarily store generated or acquired data or information in the RAM 12L. 【0046】 The wireless communication unit 14L wirelessly connects the earphone 1L and the smartphone F1, enabling transmission and reception, and transmits the audio signal processed by the audio signal input / output control unit S1L or the earphone control unit S2L ​​to the smartphone F1. The wireless communication unit 14L has an antenna ATL and performs short-range wireless communication in accordance with the Bluetooth® communication standard, for example. The wireless communication unit 14L may be provided to connect to a communication line such as Wi-Fi® or a mobile communication line. In addition, each of the earphones 1L and 1R can individually perform wireless communication with the smartphone F1 using the wireless communication unit 14L and wireless communication unit 14R. Therefore, each of the earphones 1L and 1R can receive data, audio signals, or information transmitted from the smartphone F1. 【0047】 The on / off valve 70L is communicated with the earphone control unit S2L. The on / off valve 70L operates (i.e., opens and closes) based on signals from the earphone control unit S2L. The on / off valve 70L is controlled by the earphone control unit S2L ​​to be in an open or closed state, for example, based on settings configured on the settings screen displayed on the smartphone F1. In this embodiment, for example, the on / off valve 70L is controlled based on the user's movement speed. However, the control method for the on / off valve 70L is not limited to these, and it may also be controlled based on whether or not a call is in progress. 【0048】 The F1 smartphone is a wireless terminal carried by the user. 【0049】 Next, with reference to Figure 6, an example of the hardware configuration of a smartphone will be described using a block diagram of the smartphone. Figure 6 is a diagram showing a block diagram of a smartphone according to this embodiment. The smartphone F1 includes a display / operation unit 30, a public network communication I / F unit 31, a public network protocol control unit 32, a control unit 33, a ROM 34, a RAM 35, an audio signal bus 36, an audio signal input / output control unit 37, a short-range wireless control unit 38, a wireless LAN communication I / F unit 39, an earphone communication I / F unit 40, a USB communication I / F unit 41, a location information positioning unit 42, an acceleration sensor 43, and a battery B2. In Figure 6, interface is abbreviated as "I / F". 【0050】 The display / operation unit 30, as an example of a display unit or operation unit, is configured using a touch panel that accepts user input and displays data generated by the control unit 33, thus forming a so-called user interface. The display / operation unit 30 may display various screens generated by the control unit 33. The display / operation unit 30 accepts user input on the displayed screens, generates input signals, and sends them to the control unit 33. 【0051】 The public network communication interface 31 is connected to the antenna AT3 of the smartphone F1 and performs wireless communication using a public network with a public base station (not shown) (for example, wireless communication compliant with 4G (fourth-generation mobile communication system) or 5G (fifth-generation mobile communication system) such as LTE (Long Term Evolution)). Note that the public network communication interface may be omitted from the configuration of the smartphone F1. 【0052】 The public network protocol control unit 32 performs control over data input and output between the sound signal bus 36 and the public network communication I / F unit 31. The public network protocol control unit 32 may be omitted from the configuration of the smartphone F1. 【0053】 The control unit 33 is configured using a processor such as a CPU, MPU, or DSP. It functionally has a smartphone OS processing unit 33A and a smartphone application processing unit 33B, and performs various processes and controls in cooperation with the ROM 34, each of the smartphone OS processing unit 33A and the smartphone application processing unit 33B. The control unit 33 calculates the user's movement speed (hereinafter referred to as movement speed) based on the location information of the smartphone F1 (in other words, the user's location information) obtained from the location information positioning unit 42. The user's movement speed may be measured by an external terminal and obtained by the smartphone F1. 【0054】 ROM34 contains a program that defines the operation of the control unit 33 and the data used when executing that program. ROM34 also stores identification information for the smartphone F1 and identification information for the earphone 1, which has been pre-registered (paired) as the destination for transmitting sound signals. Furthermore, ROM34 may store information related to the user's movement speed. This information could be, for example, information related to a statistically standard speed range in which the user is presumed to be walking. However, this information is not limited to a statistically standard speed range in which the user is presumed to be walking; it could also be information related to a statistically standard speed range in which the user is presumed to be running or cycling. For example, the speed range in which the user is presumed to be walking is 3 km / h to 6 km / h. This is just an example and is not limited to this range. Furthermore, the information related to the user's movement speed may be predetermined and stored in ROM34, or it may be arbitrarily determined by the user (see Figure 8). 【0055】 RAM 35 is a work memory used when executing each process of the control unit 33. Data or information generated or acquired by the control unit 33 is temporarily stored in RAM 35. 【0056】 The audio signal bus 36 performs audio signal data input and output with the control unit 33, audio signal data input and output with the public line protocol control unit 32, audio signal input / output control unit 37, and audio signal data input and output with the short-range wireless control unit 38. 【0057】 The sound signal input / output control unit 37, based on commands output from the control unit 33, sends sound signal data picked up by the microphone MC4 to the control unit 33 via the sound signal bus 36, or causes sound signals input via the sound signal bus 36 to be output from the speaker SP2. 【0058】 Microphone MC4 captures speech based on the user's utterances using smartphone F1, converts it into an audio signal, and sends the converted audio signal to the audio signal input / output control unit 37. The audio signal captured by microphone MC4 is input to the control unit 33 via the audio signal input / output control unit 37 and the audio signal bus 36. 【0059】 Speaker SP2 acoustically outputs sound signal data from the sound signal input / output control unit 37. 【0060】 The short-range wireless control unit 38 performs control over data input and output between the sound signal bus 36 and the wireless LAN communication interface unit 39, and between the sound signal bus 36 and the earphone communication interface unit 40. The short-range wireless control unit 38 sends commands output from the control unit 33 and sound signal data input via the sound signal bus 36 to the wireless LAN communication interface unit 39 or the earphone communication interface unit 40. The short-range wireless control unit 38 may also send sound signal data input from the wireless LAN communication interface unit 39 or the earphone communication interface unit 40 to the control unit 33. 【0061】 The wireless LAN communication interface 39 is connected to the antenna AT2 of the smartphone F1 and performs wireless communication with the earphone 1 via wireless LAN (for example, data transmission from the short-range wireless control unit 38). The wireless LAN communication interface 39 is configured using a communication circuit that can connect to the internet via a wireless LAN router (not shown). The wireless LAN communication interface 39 may also perform wireless communication (for example, wireless LAN such as Wi-Fi®) with each of the earphones 1L and 1R via the aforementioned wireless LAN router (not shown). 【0062】 The earphone communication interface unit 40 is connected to the antenna AT1 of the smartphone F1 and performs short-range wireless communication (for example, data transmission from the short-range wireless control unit 38) with the earphone 1 using Bluetooth®. 【0063】 The USB communication interface 41 is an interface for wired communication between the smartphone F1 and an external device (e.g., a PC (Personal Computer)) using a cable or similar means. The USB communication interface 41 is connected to the control unit 33 in a data communication manner and can transmit data from the external device to the control unit 33. Furthermore, the USB communication interface 41 may also be used to supply charge to the battery B2 from an external commercial power source. 【0064】 The positioning unit 42 is, for example, a GPS (Global Positioning System) receiver. The positioning unit 42 is connected to the antenna AT4 of the smartphone F1 and receives multiple signals indicating the time and position (coordinates) of multiple navigation satellites (i.e., GPS satellites) transmitted from multiple GPS satellites. Based on the received signals, the positioning unit 42 calculates the position of the GPS receiver (i.e., the position of the smartphone F1). The positioning unit 42 outputs the position information of the smartphone F1 to the control unit 33. 【0065】 The accelerometer 43 measures the acceleration of the smartphone F1. The acceleration of the smartphone F1 is, in other words, the acceleration of the user's movement while holding the smartphone F1. The accelerometer 43 is an inertial sensor that detects, for example, three-dimensional inertial motion (translational motion in the orthogonal three-axis directions). The accelerometer 43 transmits the measured acceleration of the smartphone F1 to the control unit 33. 【0066】 Battery B2 is a battery (e.g., a battery) capable of storing charge supplied from an external commercial power source, and it supplies power to the smartphone F1. Battery B2 may be detachable. Battery B2 may obtain power directly from an external commercial power source, or it may be capable of supplying power to the smartphone F1 even when disconnected from an external commercial power source. 【0067】 Next, we will explain the target movement speed modes with reference to Figure 7. Figure 7 is a diagram illustrating the target movement modes. 【0068】 When the user's movement speed calculated by the control unit 33 of smartphone F1 falls within a predetermined range, that user's movement speed is referred to as the target movement speed. The predetermined range is either a range stored in the ROM 34 or a range set by the user (see Figure 8). The mode in which the on / off valves 70L and 70R are controlled using the target movement speed information is called the target movement speed mode. When the control unit 33 determines that the user is moving at the target movement speed, the target movement speed mode is turned ON. When the control unit 33 determines that the user is not moving at the target movement speed, the target movement speed mode is turned OFF. When the user is not moving at the target movement speed, for example, they may be stationary or moving at high speed on a train, etc. 【0069】 Closed mode and open mode refer to the modes in which earphone 1 is open or closed. Closed mode is, for example, the mode when the user is listening to music. Note that what the user is listening to is not limited to music; it may also be sound signals related to video data or recorded data. Open mode is, for example, the mode when the user is speaking on the phone. Note that the examples of closed mode and open mode are just examples and are not limited to those above. 【0070】 The control unit 33 of smartphone F1 turns on the target movement speed mode when it detects that the user's movement speed is equal to the target movement speed. Conversely, the control unit 33 of smartphone F1 turns off the target movement speed mode when it detects that the user's movement speed deviates from the target movement speed. 【0071】 Case CA represents the sealed state of earphone 1 when target speed mode is off. When target speed mode is off and sealed mode is selected, earphone 1 is closed. When target speed mode is off and open mode is selected, earphone 1 is open. 【0072】 Case CB represents the sealed state of earphone 1 when target movement speed mode is on. When target movement speed mode is on and sealed mode is active, earphone 1 is in an open state. When target movement speed mode is on and open mode is active, earphone 1 is in an open state. In other words, in case CB, earphone 1 is in an open state regardless of whether it is in sealed or open mode. 【0073】 Next, we will explain an example of the screen for setting the opening / closing mechanism during movement, referring to Figure 8. Figure 8 is a diagram showing an example of the screen for setting the opening / closing mechanism during movement. 【0074】 The "Open / Close During Movement" setting screen MN is an example of a screen displayed on the display / operation unit 30 of the smartphone F1. The smartphone application processing unit 33B displays the "Open / Close During Movement" setting screen MN on the display / operation unit 30. 【0075】 The Movement Open / Close Settings screen MN is a screen for setting the opening and closing of the opening / closing valves 70L and 70R based on the user's movement speed (hereinafter referred to as Movement Open / Close Settings). 【0076】 Button BT is a button that switches the setting for opening and closing while moving on and off. 【0077】 Item IT1 is for setting the range of target movement speeds that the user is presumed to be walking at. The target movement speed range set in item IT1 is, for example, 3 km / h to 6 km / h. The target movement speed range set in item IT1 may be a predetermined range or may be set arbitrarily by the user. Also, the target movement speed range is just an example and is not limited to 3 km / h to 6 km / h. The target movement speed range of item IT1 is defined as a first range that is greater than or equal to the first speed and less than or equal to the second speed which is greater than the first speed. 【0078】 Item IT2 is for setting the range of target movement speeds that the user is presumed to be running at. The target movement speed range set in item IT2 is, for example, 6 km / h to 15 km / h. The target movement speed range set in item IT2 may be a predetermined range or may be set arbitrarily by the user. Also, the target movement speed range is just an example and is not limited to 6 km / h to 15 km / h. The target movement speed range of item IT2 is defined as a second range that is greater than or equal to the third speed and greater than or equal to the fourth speed and greater than the third speed. 【0079】 Item IT3 is for setting the range of target speeds that the user is presumed to be cycling at. The target speed range set in item IT3 is, for example, 15 km / h to 30 km / h. The target speed range set in item IT3 may be a predetermined range or may be set arbitrarily by the user. Also, the target speed range is just an example and is not limited to 15 km / h to 30 km / h. The target speed range for item IT3 is defined as a third range that is between the 5th speed and above the 4th speed, and between the 6th speed and above the 5th speed. 【0080】 As a result, if the movement speed falls within at least one of the first, second, and third ranges, the smartphone F1 transmits the signal to earphones 1L and 1R indicating that the user's movement speed is within a predetermined range. The earphone control unit S2L ​​of earphone 1L controls the on / off valve 70L based on the signal from smartphone F1. The earphone control unit S2R of earphone 1R controls the on / off valve 70R based on the signal from smartphone F2. 【0081】 Note that the number of configurable target movement speed ranges is not limited to walking, running, and cycling; it can be three or more. 【0082】 Item IT4 is a setting that controls the on / off valves 70R and 70L to open if the user's movement speed remains at the target movement speed for a predetermined period of time or longer. In other words, when the user presses and checks item IT4, if smartphone F1 determines that the user's movement speed remains at the target movement speed for a predetermined period of time, it sends a signal to earphone 1 indicating that the user's movement speed is at the target movement speed. Hereinafter, the time used to determine whether the user's movement speed remains at the target movement speed for a predetermined period of time will be referred to as the duration. The duration may be a predetermined time or it may be set arbitrarily by the user. The duration may be 5 minutes, for example. However, the duration is not limited to 5 minutes. 【0083】 Item IT5 is a setting that determines whether or not to consider the acceleration of the user's movement speed. In other words, the smartphone F1 determines whether the acceleration related to the user's movement, as measured by the acceleration sensor 43 of the smartphone F1, is an appropriate value for the movement speed in the first range, second range, or third range. If the smartphone F1 determines that the acceleration is within a predetermined range for each target movement speed range, it sends a signal to the earphone 1 indicating that the user's movement speed is the target movement speed. The predetermined acceleration values ​​may be stored in the ROM 34. 【0084】 Next, with reference to Figure 9, the process related to the opening and closing control of the on / off valve of the earphone control system will be explained. Figure 9 is a sequence diagram of the process related to the opening and closing control of the on / off valve of the earphone control system. 【0085】 The user performs an operation on the display / operation unit 30 of the smartphone F1 to call up the opening / closing settings screen MN (St10). 【0086】 Based on the user's operation in step St10, the smartphone F1 displays the opening / closing setting screen MN during movement on the operation unit 30 (St11). 【0087】 Smartphone F1 initiates short-range wireless communication (e.g., Bluetooth® communication) with earphone 1 (St12). The Bluetooth® communication with earphone 1 in step St12 may be initiated by user operation or may be initiated automatically by the settings of smartphone F1. 【0088】 The control unit 33 of the smartphone F1 calculates the user's movement speed based on the signal from the location information positioning unit 42 (St13). Alternatively, the user's movement speed may be measured by an external terminal capable of measuring movement speed, and the smartphone F1 may acquire the measurement result. 【0089】 The control unit 33 of the smartphone F1 determines whether the user's movement speed calculated in step St13 is the target movement speed (St14). 【0090】 Smartphone F1 sends the result of the processing in step St14 to earphone 1 (St15). 【0091】 Based on the information obtained in step St15 regarding whether the user's movement speed is the target movement speed, earphone 1 performs opening and closing control of the on / off valves 70R and 70L (St16). 【0092】 Smartphone F1 and earphone 1 repeatedly execute the processes from step St12 to step St16. 【0093】 Next, with reference to Figure 10, the process related to controlling the opening and closing of the valve according to the user's movement speed will be explained. Figure 10 is a flowchart of the process related to controlling the opening and closing of the valve according to the user's movement speed. Each process in the flowchart of Figure 10 is executed by the earphone control unit S2L ​​and the earphone control unit S2R. Since the earphone control unit S2L ​​and the earphone control unit S2R perform similar processes, the process executed by the earphone control unit S2L ​​will be explained here, and the explanation of the process executed by the earphone control unit S2R will be omitted. 【0094】 The earphone control unit S2L ​​acquires information about the user's movement speed transmitted from the smartphone F1 (St20). The information about the user's movement speed is the information obtained from the smartphone F1 in step St15 of Figure 9, which concerns whether or not the user's movement speed is the target movement speed. 【0095】 The earphone control unit S2L ​​determines whether the on / off valve 70L is currently closed (St22) if the user's movement speed is determined to be the target movement speed by the control unit 33 of the smartphone F1 (St21, YES). 【0096】 If the earphone control unit S2L ​​determines that the on / off valve 70L is not currently closed (i.e., open) (St22, NO), it leaves the on / off valve 70L open and turns on the target movement speed mode (St24). After processing in step St24, the earphone control unit S2L ​​returns to processing in step St20. 【0097】 If the earphone control unit S2L ​​determines that the on / off valve 70L is currently in the closed state (St22, YES), it controls the on / off valve 70L to open it (St23). 【0098】 In step St23, the earphone control unit S2L ​​opens the on / off valve 70L, and then turns on the target movement speed mode (St24). After the processing in step St24, the earphone control unit S2L ​​returns to the processing in step St20. 【0099】 If the earphone control unit S2L ​​determines that the user's movement speed is not the target movement speed (St21, NO) by the control unit 33 of the smartphone F1, it determines whether the earphone 1L is in sealed mode or not (St25). For example, if the user's movement speed, which was at the target movement speed, deviates from the target movement speed, the control unit 33 of the smartphone F1 determines that it is not at the target movement speed. 【0100】 If the earphone control unit S2L ​​determines that the earphone 1L is in sealed mode (St25, YES), it determines whether the on / off valve 70L is currently open (St26). 【0101】 If the earphone control unit S2L ​​determines that the on / off valve 70L is not currently in the open state (i.e., it is in the closed state) (St26, NO), it leaves the on / off valve 70L in the closed state and turns off the target movement speed mode (St28). After processing in step St28, the earphone control unit S2L ​​returns to processing in step St20. 【0102】 If the earphone control unit S2L ​​determines that the on / off valve 70L is currently in the open state (St26, YES), it controls the on / off valve 70L to close it (St27). 【0103】 In step St27, the earphone control unit S2L ​​closes the on / off valve 70L, and then turns off the target movement speed mode (St28). After the processing in step St28, the earphone control unit S2L ​​returns to the processing in step St20. 【0104】 If the earphone control unit S2L ​​determines that the earphone 1L is not in sealed mode (i.e., in open mode) (St25, NO), it determines whether the on / off valve 70L is currently in the closed state (St29). 【0105】 If the earphone control unit S2L ​​determines that the on / off valve 70L is not currently in the closed state (i.e., it is in the open state) (St29, NO), it leaves the on / off valve 70L in the open state and turns off the target movement speed mode (St31). After processing in step St31, the earphone control unit S2L ​​returns to processing in step St20. 【0106】 If the earphone control unit S2L ​​determines that the on / off valve 70L is currently in the closed state (St29, YES), it controls the on / off valve 70L to open it (St30). 【0107】 In step St30, the earphone control unit S2L ​​opens the on / off valve 70L, and then turns off the target movement speed mode (St31). After the processing in step St31, the earphone control unit S2L ​​returns to the processing in step St20. 【0108】 As described above, the control system according to this embodiment (for example, the earphone control system 100) comprises earphones (for example, earphone 1) worn on the user's left and right ears, respectively, and a wireless terminal (for example, smartphone F1) carried by the user. The earphone has a housing (for example, housing HOL and housing HOR) that has a space inside and a path that allows air to pass from one end on the user's ear canal side to the other end on the ambient environment side. The earphone has an on / off valve (for example, on / off valve 70L and on / off valve 70R) housed inside the housing that can block a part of the path. When the wireless terminal determines that the user's movement speed is within a predetermined range, it transmits a signal to the earphone indicating that the movement speed is within a predetermined range. The earphone controls the on / off valve based on the signal received from the wireless terminal. 【0109】 This allows the control system to open the earphone's on / off valve when the user's movement speed is within a predetermined range, i.e., the target movement speed. By opening the on / off valve while the user is moving, the control system can improve the ease of hearing external sounds. It can also improve listening comfort by suppressing sound reverberation within the user's body when listening to music or other audio through the earphones. As a result, the control system can control the sealed or open state of the earphones worn in the ear according to the user's movement state, thereby preventing discomfort. 【0110】 Furthermore, the earphone according to this embodiment determines whether the valve is closed or closed based on a signal acquired from a wireless terminal. If it determines that the valve is closed, it opens the valve to the open state. This allows the control system to open the valve based on the user's movement speed. As a result, the control system can automatically perform control related to the opening and closing of the valve without the user having to switch the valve's position on the wireless terminal or earphone. 【0111】 Furthermore, the wireless terminal of the control system according to this embodiment transmits a signal to the earphone indicating that the movement speed is within a predetermined range if the movement speed falls within at least one of the first, second, and third ranges. The first range is the range where the movement speed is at or above the first speed and is between the second speed and above the first speed. The second range is the range where the movement speed is at or above the third speed and is between the fourth speed and above the third speed. The third range is the range where the movement speed is at or above the fifth speed and is between the fifth speed and above the fifth speed. As a result, the control system can open the earphone when the user's movement speed falls within at least one of the first, second, or third ranges (i.e., when the user's movement speed is the target movement speed). 【0112】 Furthermore, the first range of the control system according to this embodiment is the standard speed at which a user moves by walking. The second range is the standard speed at which a user moves by running. The third range is the standard speed at which a user moves by cycling. As a result, the control system can perform control over the opening and closing of the on / off valve when a user is walking, running, or cycling, and the user can improve their ability to hear external sounds even while moving by these activities. 【0113】 Furthermore, the wireless terminal of the control system according to this embodiment transmits a signal to the earphone indicating that the movement speed is within a predetermined range when the movement speed falls within a range selected by the user from among the first, second, and third ranges. This allows the control system to control the sealed or open state of the earphone based on the settings determined by the user. This improves the convenience of the user's use of the earphone. 【0114】 Furthermore, the values ​​of the first, second, third, fourth, fifth, and sixth speeds of the control system according to this embodiment can be arbitrarily set by user operation on a wireless terminal. This allows the control system to set a range of target movement speeds according to each user's walking speed, running speed, and cycling speed. This improves the convenience of the user's use of earphones. 【0115】 Furthermore, when the wireless terminal of the control system according to this embodiment determines that the movement speed has remained within a predetermined range for a predetermined period of time or longer, it transmits a signal to the earphone indicating that the movement speed is within a predetermined range. This reduces false detections and enables the control system to perform highly accurate control of whether the earphone is sealed or open. 【0116】 Furthermore, the wireless terminal of the control system according to this embodiment measures the acceleration related to the user's movement, and if it determines that the acceleration is within the seventh range, it transmits a signal to the earphone indicating that the movement speed is within a predetermined range. This allows the control system to reduce false detections and perform highly accurate control of the sealed or open state of the earphone. 【0117】 Furthermore, the wireless terminal of the control system according to this embodiment has a display unit (for example, a display / operation unit 30), and the display unit displays a screen for setting the opening and closing of the opening and closing valve related to the user's movement (for example, the opening and closing setting screen MN during movement). The screen includes a button for setting whether or not to execute control of the opening and closing of the opening and closing valve related to movement. The screen includes a field for setting a first range, a field for setting a second range, and a field for setting a third range. The screen also includes a field for setting whether or not to consider whether or not the movement speed will remain within a predetermined range for a predetermined time or longer, and a field for setting whether or not to consider acceleration. This allows the control system to determine the setting for controlling the sealed or open state of the earphones by the user. This improves the convenience of the user's use of the earphones. 【0118】 While embodiments have been described above with reference to the attached drawings, this disclosure is not limited to such examples. It is clear to those skilled in the art that various modifications, alterations, substitutions, additions, deletions, and equivalents can be conceived within the scope of the claims, and these are also understood to fall within the technical scope of this disclosure. Furthermore, the components of the embodiments described above can be combined in any way without departing from the spirit of the invention.
