Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the adjusting circuit for the sound loudness of a single-sided channel of a headphone according to the present invention includes: the horn comprises a first horn S1, a second horn S2, a single-pole double-throw switch S3 and an adjustable delayer U1;
the first channel audio signal of the headphones is connected to a first speaker S1;
the first sound channel audio signal is also connected to the first moving end of the single-pole double-throw switch S3 through an adjustable time delay unit;
the second audio channel of the earphone is connected to the second moving end of the single-pole double-throw switch S3;
the stationary end of the single pole double throw switch S3 is connected to a second horn S2.
The delay range of the adjustable delayer is as follows: 0 to 25 milliseconds.
The first channel is a left channel; the second channel is a right channel; or
The second channel is a left channel; the first channel is a right channel.
The first horn and the second horn in the present invention have the same acoustic performance.
The idea of the present invention is described below.
The invention provides a stereo earphone which can increase the loudness (sound pressure level) of unilateral sound, and the increased decibel is adjustable within the range of 10dB, so as to meet the special requirements of a wearer.
Taking the first channel as the left channel as an example, as shown in fig. 2, it is an application scene diagram of the adjusting circuit for the loudness of sound of the single-side channel of the earphone according to the present invention. S1 and S2 are the sounding horns of the left and right channels of the stereo headphone, respectively, and their acoustic performance is the same. The distance from S1 to the left ear of the observer and the distance from S2 to the right ear of the observer are equal. A selection switch is arranged at the position of S2, when the switch is in a 1-way, S1 is a left sound channel sounder, and S2 is a right sound channel sounder; when the switch is in 2-way, the left channel signal is divided into two paths, the combination of the S2 and the delay controller is connected with the S1 in parallel, the S1 is the left channel sounder, and the S2 is the delayed left channel sounder.
As shown in fig. 3, according to the haas effect, if two sound sources are located at symmetrical positions on both right and left sides of a person, if the left and right ears of an observer receive the same signal at the same time, it feels that the sound image is located at the middle position of the two sound sources. If one of the sound sources sounds after a time delay, the observer perceives that the sound image is located between the two sound sources biased toward the sound source with priority. When the delay time exceeds 5 milliseconds, the observer perceives the sound as coming entirely from the preferentially sounding source and its sound pressure level increases by 10 dB. When the delay is less than 5 milliseconds, the subjective sound pressure difference of the two sound sources changes correspondingly from 0 to 10 dB. With a delay greater than 25 or 30 milliseconds, the observer will perceive the two sources as sounding independently.
In fig. 2, the loudness of the left channel S1 is increased as an example:
(1) when the switch is communicated with the gear 1, the earphone system is a common stereo earphone system.
(2) When the switch is connected to the gear 2, S2 is connected to S1 in parallel, and S2 also plays the left channel signal.
(3) When the gear 2 is switched on, sound pressure level gain of 0 to 10dB can be obtained by adjusting the delay of S2 relative to S1 by using an adjustable delayer within the adjustment range of 0 to 25 milliseconds. The loudness of sound output by the adjusting circuit can refer to fig. 3: when the delay of the adjustable delayer is 0-5 ms, the loudness of sound output by the adjusting circuit is increased by 0-10 dB; when the delay of the adjustable delayer is 5-25 ms, the loudness of sound output by the adjusting circuit is increased by 10 dB. In the prior art, the output volume is increased by increasing the current, and when the current reaches the maximum, the volume reaches the maximum; the adjusting circuit can increase the output volume by 0-10 dB when the current of the adjusting circuit reaches the maximum.
The invention also provides a headset which comprises the adjusting circuit for the sound loudness of the single-side channel of the headset.
As shown in fig. 4, a method for adjusting the loudness of sound of a single-side channel of a headphone according to the present invention includes:
step 31, connecting a first channel audio signal of the earphone to a first loudspeaker; meanwhile, the first sound channel audio signal is connected to a first movable end of the single-pole double-throw switch through an adjustable delayer;
step 32, connecting a second channel audio signal of the earphone to a second moving end of the single-pole double-throw switch;
step 33, connecting the immobile end of the single-pole double-throw switch to a second horn;
and step 34, connecting the first movable end and the fixed end of the single-pole double-throw switch, and adjusting the delay value of the adjustable delayer to a preset range so as to adjust the sound loudness of the first sound channel of the earphone.
The delay range of the adjustable delayer is as follows: 0 to 25 milliseconds.
The first channel is a left channel; the second channel is a right channel; or
The second channel is a left channel; the first channel is a right channel.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
