Figure 1 is a schematic perspective view of a wearable sound device 10 located on an ear 10EAR according to an embodiment of the present invention. Wearable sound device 10, such as an in-ear device, may be used as sleep earplugs. Wearable sound device 10 includes a mouthpiece device 110 .

The vent device 110 is used to form or seal a vent (such as a vent) so that the wearable sound device 10 can be in a closed state (which blocks the propagation of sound waves or increases sound attenuation) and an open state (which allows the propagation of sound waves or reduces sound attenuation). switch between. The space within the wearable sound device 10 may be divided into a first volume and a second volume. The first volume generally represents the volume within the wearable sound device 10 that is connected or will be connected to the ear canal of the ear 10EAR; the second volume generally represents the surrounding environment within the wearable sound device 10 that is connected or will be connected to the wearable sound device 10 volume. The first volume and the second volume are separated by internal components within the wearable sound device 10 . When the port is closed/sealed, the first volume and the second volume are barely connected. When a vent is formed in the vent device 110, the first volume and the second volume are connected through the vent, allowing sound/air to be discharged from one side to the other.

Generally speaking, background sound may refer to any audio outside of wearable sound device 10 , including sounds that are not typically considered noise, such as calls, alarms, speech, or music directed to wearable sound device 10 . In order to improve sleep quality in a noisy environment, the opening of the wearable sound device 10 will be closed. However, for safety reasons, the opening of the wearable sound device 10 may be formed to alert the user of the wearable sound device 10 when there is an alarm or light suddenly appears.

On the other hand, the opening of the wearable sound device 10 can, when temporarily opened, form an airflow channel between the ear canal of the ear 10EAR and the external surrounding environment to release the pressure caused by the occlusion effect and weaken the occlusion effect. However, in terms of frequency response, sound pressure levels at lower frequencies drop significantly due to the airflow channels. Therefore, when the wearable sound device 10 plays music for the user, the access port can be sealed.

In other words, the wearable sound device 10 is an earphone with a dynamic port. Dynamic vents create an airflow path between the front cavity/volume of the headset leading to the ear canal of the ear 10EAR and the external environment. In one embodiment, whether the vent of the wearable sound device 10 is open or closed (to reduce or increase sound attenuation) may depend on environmental conditions (e.g., signal type and signal strength of the environmental signal (optical/audio/smoke/motion) ). Signal types of environmental signals (optical/audio/smoke/motion) can be divided into two or more hazard levels to describe the degree of hazard.

Any mechanism that creates or blocks a vent can be used as the vent device 110 of the present invention. For example, FIG. 2 is a schematic diagram of a wearable sound device 20 according to an embodiment of the present invention. In FIG. 2 , (a) shows the port device 210 and the driving circuit 220 of the wearable sound device 20 , and (b) conceptually shows a cross-sectional view of the wearable sound device 20 . The access device 110 may be implemented by the access device 210 .

The opening device 210 may include a membrane structure 211 and an actuator 212 disposed on the membrane structure 211 . A slit can divide the membrane structure 211 into two opposite flaps 211a and 211b. The flap 211a or 211b may include an anchor end and a free end, so that the flap 211a/211b may be actuated by the actuator 212 to swing upward or downward. The movement of the free end of flap 211a may be different from the movement of the free end of flap 211b; flaps 211a and 211b may move in the same direction (eg, clockwise or counterclockwise) to form opening 213. In another embodiment, the opening may be formed when the flaps 211a/211b swing in two opposite directions (eg, clockwise and counterclockwise).

The closed state and the open state can be defined as follows: when the difference between the displacement of the free end of the flap 211a and the displacement of the free end of the flap 211b is greater than the thickness of the membrane structure 211, the passage 213 is deemed to be opened or formed. On the contrary, when the difference between the displacement of the free end of the flap 211a and the displacement of the free end of the flap 211b is at least less than the thickness of the membrane structure 211, or when the free end of the flap 211a substantially overlaps the free end of the flap 211b or is with the free end of the flap 211b, When the free ends of the flaps 211b are in physical contact, the passage 213 is deemed to be closed or sealed.

As shown in (b) of FIG. 2 , the membrane structure 211 divides the space within the housing 100 of the wearable sound device 20 into volumes 231 and 232 . The (first) volume 231 is connected or will be connected to the ear canal of the user of the wearable sound device 20 ; the (second) volume 232 is connected or will be connected to the surrounding environment of the wearable sound device 20 . When the actuator 212 is activated to temporarily open the passage 213 (between the free end of the flap 211a and the flap 211b), the volumes 231 and 232 are connected through the passage 213, so that the passage 213 communicates with the wearable sound The surrounding environment of the device 20 to the ear canal of the user of the wearable sound device 20 . This allows sound to leak or flow in. When the passage 213 is blocked, the volumes 231 and 232 are substantially disconnected, such that the surrounding environment of the wearable sound device 20 and the ear canal of the user of the wearable sound device 20 are substantially separated or isolated from each other. This will reduce or completely prevent gases from flowing or entering the wearable sound device 20, allowing the membrane structure 211 to act as a physical barrier against ambient noise.

The driving circuit 220 coupled to the vent device 210 is used to drive the actuator 212 of the vent device 210, thereby controlling the membrane structure 211 to form the vent 213 or to seal the vent 213. For example, the driving circuit 220 can apply different voltages (or apply the same voltage, such as applying a first voltage level) to the actuating portions 212a and 212b of the actuating member 212 to open the through hole 213, and apply different voltages to the actuating portions 212a and 212b of the actuating member 212. 212b applies the same voltage (eg, a second voltage level) to close the port 213, but the invention is not limited thereto. By applying a voltage to the port device 210 using the drive circuit 220, the wearable sound device 20 can be switched between a closed state (which reduces background noise) and an open state (which allows sound to flow).

Figure 3 is a schematic diagram of a wearable sound device 30 according to an embodiment of the present invention. Compared with the wearable sound device 10 , the wearable sound device 30 further includes a controller 330 and a sensing device 340 .

Sensing device 340 is used to detect/monitor environmental conditions, including those that may indicate potential hazards or activity scenarios. The sensing device 340 may be an environment sensing device, such as a sound sensing device (or sound collection device), a light sensing device, a smoke sensing device, a motion sensing device, an earthquake sensing device, a physiological state sensing device, and others. Sensor or combination thereof. The sound collection device may be a microphone or a device that captures sound from the surrounding environment and converts it into a digital format signal for further processing. The sensing device 340 can generate the sensing result SR3 according to its environment monitoring.

The controller 330 coupled to the sensing device 340 is used to decide whether to close/open the port according to the sensing result SR3 (for example, 213). In response to the determination of the controller 330 , the controller 330 may control the driving circuit (eg 220 ) coupled to the controller 330 with the control signal CS3 . In one embodiment, the (packet) size of the control signal CS3 may be small because the control signal CS3 only indicates opening or closing the port.

When the controller 330 determines to open the access port (eg, 213) according to the sensing result SR3, the controller 330 instructs the driving circuit 220 to drive the actuator (eg, 212) of the access device 110 to open the access port. For example, one flap (eg, 211a) can be actuated to have a displacement, and another flap (eg, 211b) can be actuated to have a displacement. The difference between these two displacements is greater than the thickness of the membrane structure (e.g. 211). Alternatively, one flap (eg, 211a) can move in one direction and the other flap (eg, 211b) can move in the opposite direction.

In one embodiment, the controller 330 can generate the control signal CS3 according to the environmental background state to dynamically control the port during sleep. In one embodiment, the sensing value displayed by the sensing result SR3 represents the size of the environmental noise, and the opening degree of the port is related to the sensing value. For example, as ambient noise becomes louder, the opening of the port decreases (or increases). The vent can be closed with a noisy background and opened with a non-noisy background. If the level of background interference is moderate, the port can also support a semi-closed state. Accordingly, the vent of the wearable sound device 30 can filter out loud non-music sounds to improve sleep quality.

Figure 4 is a schematic diagram of a controller 430 according to an embodiment of the present invention. Controller 330 may be implemented by controller 430. The controller 430 may include a feature extraction unit 431 (used to perform a feature extraction operation) and a context classification unit 432 (used to perform a context classification operation). The feature extraction unit 431 and the situation classification unit 432 can be implemented by a combination of software, firmware and/or hardware. For example, the feature extraction unit 431 and the situation classification unit 432 can be implemented by a control circuit, a processing circuit (such as a digital signal processor), or an application-specific integrated circuit, but are not limited thereto.

The feature extraction unit 431 may extract features from the sensing results (for example, SR3) received by the feature extraction unit 431. For example, the sensing results may be related to sounds, such as snoring, fire alarms, music, or other environmental sounds. Accordingly, the feature extraction unit 431 can map the sensing results in digital format to features that are easier to perform auditory-based analysis to perform auditory-based digital feature extraction. Alternatively, the feature extraction unit 431 may detect specific keywords (such as help or the user's name) or sound patterns (such as ambulance sirens or fire alarms) from the sensing results. Feature extraction operations may include fast Fourier transform or mel frequency cepstrum coefficients. Alternatively, the feature extraction unit 431 can extract the intensity and spectral bandwidth of the sensing result to perform digital feature extraction.

The situation classification unit 432 can summarize the characteristics of the features extracted by the feature extraction unit 431 and classify the extracted features into specific situations. For example, in the auditory context classification operation, the context classification unit 432 may identify a pattern of auditory-based features provided by the feature extraction unit 431 to classify the surrounding space (eg, bedroom) as a noisy background or a non-noisy background. Noisy backgrounds can include air/vehicle traffic or auditory objects such as snoring. Alternatively, in the situation classification operation, the situation classification unit 432 may analyze the features provided by the feature extraction unit 431 (such as the spectral characteristics of the optical radiation of the sensing result) to detect/identify the presence of fire or smoke, and classify the surrounding space as Danger zone, harmful zone or safe zone. Depending on its classification, the context classification unit 432 may generate and transmit a control signal (eg, CS3) to a driver circuit (eg, 220) or a port device (eg, 110). Accordingly, the controller 430 can determine whether to seal/open the port, and output a control signal to adjust the port.

Figure 5 is a schematic diagram of a controller 530 according to an embodiment of the present invention. Controller 330 may be implemented by controller 530. The controller 530 may include an artificial intelligence unit 533 for performing feature extraction operations and context classification operations. Similar to the feature extraction unit 431 and the situation classification unit 432, the artificial intelligence unit 533 may be implemented by a combination of software, firmware and/or hardware (such as a control/processing circuit or an application specific integrated circuit).

When the sensing result (such as SR3) to be interpreted/recognized is input to the trained artificial intelligence unit 533 of the controller 530, the trained artificial intelligence unit 533 can use its optimized parameters to infer the sensing result to generate/ Output the control signal (eg CS3) and transmit it to the driver circuit (eg 220) or pass device (eg 110). That is, the controller 530 applies/uses the knowledge of the artificial intelligence unit 533 to infer predictions. The artificial intelligence algorithm of the artificial intelligence unit 533 may include supervised learning, unsupervised learning or reinforcement learning. The artificial intelligence algorithm of the artificial intelligence unit 533 may include a neural network layer, such as a convolutional neural network, a recurrent neural network, or a long short-term memory network. Accordingly, the controller 530 can determine whether to seal/open the port, and output a control signal to adjust the port.

Figure 6 is a schematic diagram of a wearable sound device 60 according to an embodiment of the present invention. Compared with the wearable sound device 10 , the wearable sound device 60 further includes a controller 630 .

The controller 630 is used to receive the instruction signal DS6 and decide whether to open/close the port according to the instruction signal DS6. Controller 330 may then control the drive circuit (eg, 220 ) with control signal CS3 in response to its determination. The indication signal DS6 may be an alarm signal, such as an alarm clock or a home alarm. The indication signal DS6 can be sent by an IoT device such as a smartphone or an earthquake early warning system. The controller 630 and IoT devices can be assigned Internet Protocol (IP) addresses and can transmit data over the network.

(a) and (b) of Figure 7 illustrate wearable sound devices 70a and 70b respectively. The controller 330/630 is used to decide whether to close/open the vent. The vent device 110 of the wearable sound device 70a or 70b is controlled by the controller 330 or 630 using the control signal CS3 to form a vent or a sealed vent. Vent device 110 (or wearable sound device 70a or 70b) may generally represent a device that can be controlled to form a vent (to communicate a first volume with a second volume) or to seal a vent, and is not limited to including membrane structure 211 The opening device 210. The port device 110 of the wearable sound device 70a or 70b may include elements that may move linearly or nonlinearly in response to the voltage level of the control signal CS3. For example, port device 110 (or wearable sound device 70a or 70b) may include only one flap that may swing in response to the voltage level of control signal CS3. Wearable sound device 70a or 70b may lack driver circuit 220.
