Abstract: An earphone with a plurality of supporting portions includes a main cavity, an ear hook, and a secondary cavity; the main cavity is connected to the secondary cavity through the ear hook; the main cavity is used for mounting of a loudspeaker, and located on an anterior side of an ear; a sound outlet is provided in a position of the main cavity close to an ear canal; the ear hook is used for surrounding a superior side and a posterior side of the ear; and the secondary cavity is used for making contact with the posterior side of the ear. With the design of supporting regions of the earphone, the earphone fits the ear better, stress is more uniform, the earphone is prevented from falling off or getting loose easily, fatigue of the ear caused after long-time wearing is relieved, and the comfort of wearing is improved.

Abstract: The present invention discloses an open-ear hook-type wearable sound producing device, including a main body and an ear hook connected to the main body, wherein at least one speaker and at least one microphone are arranged in the main body; one side, facing a human ear, of the main body is provided with a forward vent; a distance between the orifice of the forward vent and an ear canal entrance point (EEP) is 0.1 to 50 mm; and a distance between a pickup end of the at least one microphone and the EEP is 0.5 to 10 mm. The structure and layout of the present invention are rational, which is helpful to improve noise cancellation performance and is suitable to wear for long listening sessions.

Abstract: Disclosed is a suspended audio device with bass enhancement performance, including a low-pass filter, a high-pass filter, an energy controller and a harmonic generator. The low-pass filter is configured to extract a low-frequency signal in an original input signal, and input the low-frequency signal as a fundamental wave of the harmonic generator; the high-pass filter is configured to extract a mid-high frequency signal in the original input signal; the harmonic generator is configured to process the low-frequency signal extracted by the low-pass filter through the NLD algorithm, and generate at least one enhanced harmonic signal in the low-frequency signal; the energy controller is configured to control an overall gain of the at least one enhanced harmonic signal generated by the harmonic generator.

Abstract: The present application discloses an anti-wind noise earphone device. The anti-wind noise earphone device includes a shell, a first pickup hole and a second pickup hole, the first pickup hole and the second pickup hole being provided in the same side of the shell, the first pickup hole communicating with the second pickup hole via a channel, the channel communicating with a microphone. According to the present application, the first pickup hole and the second pickup hole communicate with each other via the channel, so as to channel and eliminate wind noise energy and achieve the purpose of eliminating wind noise, the structure is simple, and the effect of eliminating wind noise is obvious.

Abstract: The present disclosure provides a hearing protection method capable of blocking external high-sound-pressure-level energy, including: a second sound pressure energy threshold being greater than a first sound pressure energy threshold; when an external sound energy value is greater than the first sound pressure energy threshold and is less than the second sound pressure energy threshold, enabling a preset active noise cancellation function; and when the external sound energy value is greater than the second sound pressure energy threshold, disabling the preset active noise cancellation function, and blocking high-sound-pressure-level energy by means of passive noise cancellation. The present disclosure can block the external high-sound-pressure-level energy.
