The present invention relates to a hearing device (1), in particular a hearing aid (2), comprising an earbud (17) having a first distance sensor (18) and a second distance sensor (20) and a control unit (26), wherein the first distance sensor (18) is designed to transmit the first distance signal (18a) to the control unit (26), wherein the second distance sensor (20) is designed to transmit the second distance signal (20a) to the control unit (26), wherein the earbuds (17) for the hearing device (1) the operation can be at least partially inserted into the external auditory canal of the user of the hearing device (1), and wherein the control unit (26) is designed to control the operating state of the hearing device (1) according to the change of the first distance signal (18a) and the second distance signal (20a). The present invention further relates to a method for controlling a hearing device (1) (40).

The invention discloses an earplug type alarm clock based on bone conduction, comprising an earplug head with one end used for plugging the ear, an earplug shaft piece connected with the earplug head at the front end, and an earplug sleeve slidable along the axial direction of the earplug shaft piece, A sliding block installed on the earplug sleeve and used to impact the earplug head, and a driving device installed on the earplug sleeve and used to drive the earplug sleeve to slide or vibrate. When working, the sliding block moves along the axial direction of the earplug shaft; if the earplug sleeve receives less resistance in the axial direction, the sliding block reciprocates along the axial direction; the earplugs are more resistant in the axial direction. The micro controller controls the earplug sleeve itself to vibrate itself, so that the vibration is transmitted to the user's brain through bone conduction, so as to wake up the user. The present invention has a compact structure and is closely integrated with the ear, so that the user's auditory system is isolated from the outside world, the work and rest are not disturbed, and others are not affected.

An earplug dispensing mechanism defining a longitudinal axis and including a divider assembly and an indexing assembly is disclosed. The divider assembly includes a platform, a guide wall and an aperture. The guide wall projects from the platform to define a well for receiving the earplug from the receptacle. Each hole opens to the well at an inlet opening. The guide wall forms the shape of a closed compound curve in a plane perpendicular to the longitudinal axis and surrounding the inlet opening. The indexing assembly is rotatably coupled to the divider assembly and includes a handle, a plate, and a mixing body. The plate is connected to the handle and defines a dispensing hole. The mixing body is attached to the side of the plate opposite the handle. Rotation of the handle selectively aligns the dispensing aperture with a single one of the apertures, with the guide wall shaped to drain the earplug into the well toward the aperture.

When an elevator is lifted, an ear blockage phenomenon occurs due to changes of an internal pressure of an elevator car. The internal pressure of the elevator car is changed repeatedly between two different pressure change rates so that a control method inducing passengers' swallow actions can effectively ease the ear blockage phenomenon. However, in existing control methods, the pressure in the elevator car needs to be repeatedly switched to be a positive pressure and a negative pressure relative to the atmospheric pressure in a short time, and problems that a structure of a control device and a control method are complex exist. When the elevator goes down, a positive pressure state in the elevator car is only used to form stair-stepping pressure control in the first half of the running time (T<T0), and a negative pressure state in the elevator car is only used to form the stair-stepping pressure control in the second half of the running time (T>T0). Therefore, the pressure control device only needs to implement switchover once, that is to say, a pressurized state is switched into a pressure reducing state, and the pressure control can be realized.
