[embodiment]
With reference to the accompanying drawings portable terminal computer apparatus for automatically regulating sound volume and method in this invention are elaborated.
At first, in apparatus for automatically regulating sound volume in this invention and method the portable terminal computer applicable to structure as shown in Figure 1; For example, be applicable in this invention portable terminal computer audio codec 18 as shown in Figure 2, by can decide input amplifier (hereinafter to be referred as AMP) 182 that the above amplification of grade handles to carry out institute by the noise ingredient noise grade of microphone input, can enough decibel (dB) values detect by above-mentioned input AMP by amplification be decide noise monitor 183, the generation calling reception ring prompting of the above noise ingredient noise of grade grade and the audio signal processor 181 that carries out signal processing; Adjusting is formed by the devices such as output AMP180 of the tinkle of bells output level of sound equipment output.
On the one hand, when portable terminal computer receives call signal, above-mentioned master chip 11 will start (Enable) above-mentioned microphone 19, and the input AMP182 gain-adjusted that will be arranged on above-mentioned microphone rear end to set in advance decide yield value, noise ingredient noise grade amplification that then will be by microphone input to decide more than the grade, export again.
And it is above-mentioned noise ingredient noise grade of deciding more than the grade that above-mentioned noise monitor 183 detects by amplification with decibel (dB) value, and is sent in the above-mentioned master chip 11; Behind the decibel value that above-mentioned master chip 11 is confirmed to receive from above-mentioned noise monitor, search is kept at the look-up table (Lookup Table) on the portable terminal computer flash memory 13 in advance.
On the one hand, record in the above-mentioned as shown in Figure 3 look-up table and most the corresponding output of noise grade value AMP gain-adjusted values; For example, the kinds of experiments result of above-mentioned look-up table by implementing in the portable terminal computer manufacture process can preserve flash memory as non-volatility memorizer etc. in advance.
For example, record noise grade value (Noise Value) and corresponding with it output AMP gain-adjusted value (Gain Control Value) with the form form in the above-mentioned look-up table, when if sound level value minimum is ' 30dB ', the gain-adjusted value minimum of output AMP is registered as ' 0.5V '; When if noise grade value is '+60dB ' to the maximum, the gain-adjusted value maximum of output AMP is registered as ' 5.0V '.
In addition, above-mentioned master chip 11 is by the above-mentioned look-up table of search, read the corresponding output of detected sound level value AMP gain-adjusted value with above-mentioned noise monitor, regulate above-mentioned output AMP180 then, control above-mentioned audio signal processor 181 simultaneously, be adjusted to the output level that compares with noise ingredient noise grade automatically calling out the reception ring prompting; To being described in more detail below this.Fig. 4 is the workflow displayed map of portable terminal computer volume automatic regulating method in this invention; As telling about the front, above-mentioned master chip 11 detects whether receive call signal (step S10) by wireless module 10; If the call signal of receiving will start (Enable) and close microphone 19 (step S11) in (Disable) state.
And, be arranged on input AMP182 yield value on above-mentioned microphone 19 rear ends be adjusted to prior setting decide yield value (step S12), and noise ingredient noise amplification that will be by the microphone input is by being decided more than the grade; It is the above-mentioned noise ingredient noise of deciding more than the grade that above-mentioned noise monitor 183 detects by amplification with decibel (dB) value, and outputs in the above-mentioned master chip.
On the one hand, when detecting the decibel value microphone input noise that is detected by above-mentioned noise monitor 183 (step S13), above-mentioned master chip 11 will be confirmed this decibel value, and searches for/read any one output AMP yield value (step S14) the look-up table on being kept at above-mentioned flash memory 13 in advance.
For example, when detecting ' 30dB ' noise grade value, the output AMP gain-adjusted value of above-mentioned master chip on being kept at above-mentioned look-up table in advance, read the output AMP gain-adjusted value of ' 0.5V ' by above-mentioned noise monitor; When above-mentioned noise monitor detects '+60dB ' noise grade value, from the above-mentioned output AMP gain-adjusted value that is kept in advance the look-up table, read the output AMP gain-adjusted value of ' 5.0V '.
And, utilize the output AMP gain-adjusted value that from above-mentioned look-up table, reads, regulate the yield value of above-mentioned output AMP, control above-mentioned video signal preprocessor 181 simultaneously, the tinkle of bells that receives is called out in generation/output prompting; Therefore, can carry out suitable automatic adjusting to the tinkle of bells output level according to noise grade value by above-mentioned microphone 17 inputs by sound equipment 17 outputs.
On the one hand, above-mentioned master chip 11 by with above-mentioned companion chip 14 between be connected, whether monitoring user by passing through key; When the user informs the commencing signal of conversation beginning by talk key or by the input of other input units (step S16), above-mentioned companion chip 14 corresponding signal with it outputs in the master chip; And above-mentioned master chip 11 will be imported the AMP yield value and output AMP yield value is reset (Reset) to original value, control the output (step S17) that above-mentioned audio signal processor 181 stops the tinkle of bells simultaneously.
And the user carries out normal telephone relation (step S18) by being arranged on microphone 19 on the portable terminal computer and sound equipment and the other side.
By above-mentioned design, when the user is in noise pilosity place, will heightens automatically and call out reception ring prompting output level; When the user is in the place that does not almost have noise, will turn down to call out receiving the ring prompting output level automatically, guarantee the output of suitable grade the tinkle of bells with this.
By above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.
Therefore, the technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to interest field.
