Ear mold and open-type intra-aural receiving deaf-aid

Abstract

The invention discloses an ear mold which is matched with an intra-aural receiver of a deaf-aid for working. The ear mold comprises an ear mold head and a sound transmission device connected with the ear mold head; the sound transmission device is used for being connected with a loudspeaker of the deaf-aid; the ear mold head and the sound transmission device are integrally arranged; the end of the sound transmission device, connected with the deaf-aid, has elasticity; and the connection section of the sound transmission device and the ear mold head is flexible. The invention also discloses a corresponding open-type intra-aural receiving deaf-aid which is used for assisting the positioning and the sound transmission of the intra-aural receiver of the deaf-aid in ear canals and obviously improving the effective output efficiency of the deaf-aid.

Description

technical field [0001] The present invention relates to an ear mold, in particular to an ear mold applied to an in-ear receiver for a hearing aid, which facilitates the fixing of the in-ear receiver in the ear and assists the hearing aid to improve the gain performance and wearing comfort of the hearing aid ; The present invention also relates to a corresponding open ear hearing aid device. Background technique [0002] At present, manufacturers of hearing aids generally focus on improving the output signal of hearing aids, suppressing environmental noise, sound reflection signals, etc., to ensure the quality of the output signal. The result is that even if the quality of the output signal is very good, the user actually receives very little gain, and the user cannot obtain a good effect. Because hearing aids are generally placed on the pinna, the amplified sound or gain from the speaker or receiver is still some distance away from the human eardrum. Due to the interaction ...

Problems solved by technology

[0005] However, how to position the hearing aid relatively stably inside the ear, and ensure that the part of the hearing aid inserted into the human ear can freely enter and exit the ear without causing strong discomfort to the human ear; In addition, how to ensure that the in-ear receiving device of the hearing aid will not cause ear canal muscle movement and relative movement with the in-ear receiving device due to speaking, eating, drinking, human body movement, etc., causing the in-ear receiving device to be fixed Instability, leakage of high-frequency sound pressure generated in the ear, resulting in loss of gain, and how to ensure that the low-frequency sound pressure generated by the occlusion effect can be released in a timely and appropriate manner, these technical problems need to be optimized and analyzed separately. In the existing hearing aid technology, Few exposures and excellent solutions
