Background technology
Hearing aids is the sound wave picked up by receiver in air, and converts sound wave to the signal of telecommunication, and then is amplified as required by signal, then is converted into the instrument of the sound that user can be allowed to hear, unit or instrument.But when being used by the radio communication device such as hearing aids and mobile phone simultaneously, the antenna of radio communication device generates an electromagnetic field around the receiver of radio communication device.These electromagnetic fields occur pulsation by by the receiver of hearing aids or telephone induction coil (telecoil) circuit pickup, noise may be produced in hearing aids, make radio communication device and hearing aids incompatible.Therefore, when needs judge a kind of radio communication device whether hearing aid compatible time, need whether to measure this kind of radio communication device to the interference of hearing aids lower than certain compatibility determination standard.For setting up the compatibility determination standard of radio communication device and hearing aids, US Federal Communication Committee (federal communications commission, FCC) announce and implement hearing aid compatibility (hearing aid compatibility, HAC) certification scheme, in order to assess the annoyance level of electromagnetic field to hearing aids of wireless communication apparatus, thus judge whether radio communication device is suitable for coordinating hearing aids to use.
Refer to Fig. 1, HAC standard mainly comprises radio frequency (RF) and launches (M level) and telephone induction coil coupling (T level).Wherein " M level " refers to the radio-frequency transmissions ability of radio communication device, and general M higher grade, then the radio-frequency transmissions energy level that has of radio communication device and lower to the interference of hearing aids, and the signal quality that hearing aids has is higher.And " T level " refers to the coupling ability of radio communication device, general T higher grade, then user uses the effect of radio communication device and hearing aids better simultaneously.
But existing radio communication device, in order to improve its transmitting-receiving performance, generally makes radio communication device have higher total radiant power (total radiated power, TRP).Once TRP value is excessive, then by comparatively strong for the electromagnetic field caused near wireless communication apparatus receiver, makes M lower grade, be unfavorable for the reception of hearing aids, the compatibility of both impacts.
Summary of the invention
In view of above content, be necessary to provide a kind of can the radio communication device of effective hearing aid compatible.
A kind of radio communication device, comprises circuit board and the receiver that is arranged on this circuit board and Anneta module; This radio communication device also comprises hearing aids compatible modules, this hearing aids compatible modules is arranged near Anneta module, this hearing aids compatible modules comprises earthing member, described earthing member comprises the first grounding parts, the second grounding parts and connecting portion, the shape of described first grounding parts and the second grounding parts and structure identical and be symmetrical arranged, this connecting portion then vertically connects this first grounding parts and the second grounding parts, when radio communication device works, this earthing member is equivalent to an antenna, in order to improve the sense of current of Anneta module, and then the electric field improved near this receiver and magnetic field.
Above-mentioned radio communication device is by arranging this hearing aids compatible modules, while the total radiant power not needing increase radio communication device, effectively can reduce the electric field near this receiver and magnetic field intensity, make this radio communication device meet HAC specification, and have and preferably receive and dispatch performance.
