Description

Neck hanging type sound box hearing aid

Technical Field

The utility model relates to a audiphone technical field, concretely relates to hanging audio amplifier audiphone of neck.

Background

The hearing aid is a small-sized loudspeaker, which enlarges the originally inaudible sound and then utilizes the residual hearing of the hearing-impaired person to enable the sound to be transmitted to the auditory center of the brain so as to feel the sound. Currently, hearing aids include bone conduction hearing aids and air conduction hearing aids in a conductive manner. The bone conduction hearing aid directly transmits sound waves to the inner ear through skull vibration without passing through a tympanic membrane, the bone conduction hearing aid needs to be tightly attached to the head when in use, the requirements on the wearing mode and the wearing position are extremely strict, the maximum output of the bone conduction hearing aid is far lower than the optimal values on the same frequency and all frequencies, the hearing aid frequency is narrower, the compensation on low frequency and high frequency is not ideal, and the hearing aid effect needs to be improved; at present common air conduction audiphone mainly is ear back formula and ear in formula, because this kind of audiphone sound wave directly gets into the duct, causes the eardrum damage easily when the volume is too big, and uses wearing travelling comfort of ear back formula and ear in formula audiphone extremely poor, is difficult for being accepted by the hearing impaired personage.

The wearing formula wireless sound box that purchases in the existing market mainly functions lie in that music is appreciated and is connect the dial-up telephone, and this audio amplifier is convenient to wear and has taken into account the travelling comfort of wearing, but this audio amplifier need use as cell-phone or bluetooth player collocation with other equipment, can't optimize and enlarge the sound in the scene, can't directly use as the audiphone, consequently need to carry out adaptability to this equipment and reform transform, make it become the auxiliary hearing instrument who is applicable to hearing impaired personage.

In one embodiment of the present invention, the directional microphones are three in number, and are respectively located at two branch ends and a connecting portion of the U-shaped housing, and the sound collecting directions are respectively directed to the left front side, the right front side and the rear side.

In another embodiment of the present invention, the directional microphones are five in total, four directional microphones are located at two branch ends of the U-shaped housing, the sound collecting directions are respectively directed to the front side and the two sides, one directional microphone is located at a connecting portion of the U-shaped housing, the sound collecting direction is directed to the rear side, and the directional microphones are basically required to cover the surrounding area as much as possible and the sound collecting direction is not overlapped with the sound emitting area of the speaker as much as possible.

As an improvement, a wireless communication module is further arranged in the U-shaped shell, the wireless communication module is electrically connected with the power amplifier, and the wireless communication module is in communication connection with the wireless microphone. The hearing-impaired person can wear the wireless microphone to additionally receive sound signals, so that the pickup accuracy is ensured, and the wireless microphone is used as an important supplement for a directional microphone to collect a sound source.

Further, the wireless module includes, but is not limited to, a 2.4G wireless module, a bluetooth module, an infrared module, a ZigBee module, and a WiFi module.

In order to guarantee the long-time use of the hearing-impaired user to the loudspeaker, the power supply is arranged in the battery compartment, the opening of the battery compartment is positioned on the upper surface of the U-shaped shell, and the battery is replaced to ensure the cruising ability of the hearing aid.

The neck hanging type sound box hearing aid of the utility model is convenient and comfortable to wear, and collects surrounding environment sound by adopting a multi-point pickup mode, and pickup is clear; the power amplifier and the loudspeaker are matched for use, the sound effect is better than that of bone conduction hearing aids, behind-the-ear hearing aids and in-the-ear hearing aids, and the power amplifier and the loudspeaker are worth popularizing.
