Description

Vibration reduction type voice call terminal

Technical Field

The utility model relates to a pronunciation hands-free conversation field, concretely relates to voice call terminal.

Background

The use of speech systems is common. For example, in a teleconferencing system, participants are typically grouped together in an office or conference room and seated in different locations in the room. The rooms being used are typically not equipped with special sound cutting material and the echo of the near and far end sounds increases the noise level. If the room is large enough, some participants may sit away from the telephone table, taking themselves away from the microphone. Some participants may not speak actively or only occasionally. However, their presence increases the number of room noise sources, as pencils can be knocked, paper can be rustling, and private conversations can occur. These sources of noise further degrade the sound quality experienced by a group of people at a remote location. Most speech systems have microphones deployed at one, two or at most three locations. These microphones are typically placed on the conference table surface and distributed in a way that provides the best use for the most important contributors to the conference. This choice of microphone location may be difficult for some contributors to hear. When occasional participants speak, they are often forced to close up against the microphone, which undoubtedly generates additional room noise, because they swap places or move the chair. Microphone arrays are generally designed as free-field devices, and in some cases are embedded within buildings. A problem with prior art microphone arrays is that the beam width decreases with increasing frequency. Microphones with "pancake directivity" for use in speech systems are known. For example, directional microphone devices covering 360 degrees in the horizontal plane exist in the field of telecom and conference hands-free telephony. In order to make conference hands-free telephones efficient, various microphone arrays have been used. A problem with these systems is that the speakerphone type system may show different types of echoes and even howling may occur. For example, acoustic echoes from feedback in the acoustic path between the telephone's speaker and its microphone are prone to howling when using the hands-free function due to: the signal of the near-end receiver is fed back to the near-end microphone through an acoustic path and then returns from the network side tone or the acoustic path of the opposite end, so that feedback is formed, and howling is formed if the feedback becomes positive feedback. Howling has a relatively large effect on the microphone, for example, delayed feedback of the loudspeaker sound field will cause the whole system to form a series of delayed echoes, and such echoes will emphasize the comb filtering effect and produce a significantly distorted reverberation tail.

Because loudspeaker and microphone are installed in same box, the sound vibration of sending of loudspeaker can be given the microphone for, and influence microphone pickup effect.
