The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The wireless earphone, the wireless earphone accessory and the earphone system provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
The present application provides a wireless headset 10, the appearance of which wireless headset 10 is illustrated schematically in fig. 1. As shown in fig. 1, at least two metal mating connection portions are provided on the housing of the wireless earphone 10. The two metal mating connections are a first mating connection 101 and a second mating connection 102, respectively. The two metal mating connections may be embodied in the form of gold fingers, or in the form of metal contacts, for example.
In addition, as shown in fig. 2, the wireless earphone 10 may be configured as shown in fig. 2. Specifically, the wireless earphone 10 further includes a wireless codec module 103, a micro-processing unit 104, a digital signal processing unit 105, a digital-to-analog converter 106, and a first sound generating unit 107 on the basis of including the first mating connection portion 101 and the second mating connection portion 102. Wherein the output terminal of the wireless codec module 103 is electrically connected to a first input terminal of the digital signal processing unit 105. An output of the digital signal processing unit 105 is electrically connected to an input of the digital-to-analog converter 106. A first output terminal of the digital-to-analog converter 106 is electrically connected to the first mating connection 101, and a second output terminal of the digital-to-analog converter 106 is electrically connected to an input terminal of the first sound generating unit 107. An input end of the micro-processing unit 104 is electrically connected to the second mating connection 101, and an output end of the micro-processing unit 104 is electrically connected to a second input end of the digital signal processing unit 105.
And, the wireless earphone is suitable for adapting to connect with the earphone fitting, under the condition that the wireless earphone is adapted to the earphone fitting, the first matching connection part 101 is electrically connected with the fifth matching connection part 203 of the wireless earphone fitting 20, and the second matching connection part 102 is electrically connected with the sixth matching connection part 204 of the wireless earphone fitting 20, and the second sounding unit in the wireless earphone fitting 20 plays the audio file output by the digital-to-analog converter 106.
In the embodiment of the present application, the wireless codec module 103 receives the wireless signal transmitted by the wireless signal transmitting device through the wireless transmission protocol, and decodes the wireless signal to obtain the decoded digital audio file. After the decoded digital audio file is obtained, the wireless codec module 103 inputs the decoded digital audio file to the digital signal processing unit 105 through its own output terminal. The wireless signal transmitting device can be a mobile phone, a tablet personal computer, an MP3 and the like.
The digital signal processing unit 105, after receiving the decoded digital audio file transmitted from the wireless codec module 103, performs an audio processing algorithm on the decoded digital audio file to perform noise reduction, equalization adjustment, and the like on the decoded digital audio file. The digital signal processing unit 105 outputs the digital audio file obtained by executing the audio processing algorithm to the digital-to-analog converter 106 through its own output terminal. Wherein the audio processing algorithm in the digital signal processing unit 105 is set by the micro-processing unit 104.
The digital-to-analog converter 106, upon receiving the processed digital audio file, converts the processed digital audio file into an analog audio file.
In case the user places the wireless headset 10 in the wireless headset accessory 20, i.e. in case the wireless headset is fitted with the wireless headset accessory, the first mating connection 101 in the wireless headset 10 is electrically connected with the fifth mating connection 203 of the wireless headset accessory 20 and the second mating connection 102 is electrically connected with the sixth mating connection 204 of the wireless headset accessory 20. At this time, the microprocessor unit 104 controls the first sound generating unit 107 to be powered down, i.e., controls the first sound generating unit 107 not to operate, after determining that the second mating connection portion 102 is electrically connected to the sixth mating connection portion 204 of the wireless headset accessory 20. In this way, the path between the digital-to-analog converter 106 and the first sound generation unit 107 is disconnected due to the power-down of the first sound generation unit 107.
Meanwhile, since the first mating connection portion 101 in the wireless earphone 10 is electrically connected to the fifth mating connection portion 203 of the wireless earphone fitting 20, and the fifth mating connection portion 203 of the wireless earphone fitting 20 is an input end of the second sound emitting unit 201 in the wireless earphone fitting 20, the digital-to-analog converter 106 is in conduction with a path between the second sound emitting unit 201 in the wireless earphone fitting 20. At this time, the digital-analog converter 106 outputs the converted analog audio file to the second sound generating unit 201 of the wireless headset 20 through the first output terminal thereof, and the second sound generating unit 201 of the wireless headset 20 plays the analog audio file.
The specific process of the micro-processing unit 104 controlling the first sound generating unit 107 to power down may be: the micro-processing unit 104 transmits a notification signal to stop the power supply to the first sound generating unit 107 to the first power management module 108 of the wireless headset 10. The first power management module 108 stops the power supply to the first sound generating unit 107 upon receiving the notification signal. At this time, the first sound generating unit 107 is powered down. And the volume of the second sound generating unit 201 in the wireless headset assembly 20 is larger than the volume of the first sound generating unit 107 in the wireless headset 10.
Since the volume of the second sound generating unit 201 in the wireless earphone accessory 20 is larger than the volume of the first sound generating unit 107 in the wireless earphone 10, the volume of the voice coil, the diaphragm, the equalizer, etc. in the second sound generating unit 201 is also larger than the corresponding components in the wireless earphone 10. In this way, when the analog audio file output by the digital-to-analog converter 106 is output, the second sound generating unit 201 can make the frequency loudness and the loudness of the analog audio file reach ideal values, and can also improve the sensitivity of the analog audio file.
Correspondingly, in case the user does not place the wireless headset 10 in the wireless headset accessory 20, i.e. the wireless headset is not adapted to the wireless headset accessory, the first mating connection portion 101 in the wireless headset 10 is not electrically connected to the fifth mating connection portion 203 of the wireless headset accessory 20 and the second mating connection portion 102 is not electrically connected to the sixth mating connection portion 204 of the wireless headset accessory 20. At this time, the path between the digital-to-analog converter 106 and the second sound generating unit 201 of the wireless headset assembly 20 is disconnected. Meanwhile, the micro-processing unit 104 does not perform any processing, i.e., the first sound generation unit 107 is continuously powered up. Based on this, the path between the digital-to-analog converter 106 and the first sound generating unit 107 is turned on. The first sound generation unit 107 plays the analog audio file output from the digital-to-analog converter 106. In this way, the wireless headset 10 can be ensured to work properly.
In an embodiment of the present application, a wireless headset includes: the wireless earphone comprises a wireless coding and decoding module, a micro-processing unit, a digital signal processing unit, a digital-to-analog converter, a first sound generating unit and a first matching connection part and a second matching connection part which are arranged on a wireless earphone shell; the output end of the wireless coding and decoding module is electrically connected with the first input end of the digital signal processing unit; the output end of the digital signal processing unit is electrically connected with the input end of the digital-to-analog converter; the first output end of the digital-to-analog converter is electrically connected with the first matching connection part, and the second output end of the digital-to-analog converter is electrically connected with the input end of the first sound generating unit; the input end of the micro-processing unit is electrically connected with the second matching connection part, and the output end of the micro-processing unit is electrically connected with the second input end of the digital signal processing unit; the wireless earphone is suitable for being connected with wireless earphone accessory adaptation, under the condition that wireless earphone and wireless earphone accessory adaptation, first cooperation connecting portion is connected with wireless earphone accessory's fifth cooperation connecting portion electricity, and second cooperation connecting portion is connected with wireless earphone accessory's sixth cooperation connecting portion electricity, and the audio file of digital-to-analog converter output is broadcast to the second sound unit in the earphone accessory. In this way, since the volume of the second sound generating unit in the wireless earphone accessory is larger than the volume of the first sound generating unit in the wireless earphone, the volume of the voice coil, the vibrating diaphragm, the equalizer and the like in the second sound generating unit are also larger than the corresponding components in the wireless earphone. Therefore, when the second sounding unit outputs the analog audio file output by the digital-to-analog converter, the frequency loudness and the loudness of the analog audio file can reach ideal values and the like, and meanwhile, the sensitivity of the analog audio file can be improved, namely, good hearing can be output to a user.
On the basis of any of the above embodiments, in the case where the wireless headset is not adapted to the wireless headset accessory, the first mating connection portion 101 is not electrically connected to the fifth mating connection portion 203 of the wireless headset accessory 20, and the second mating connection portion 102 is not electrically connected to the sixth mating connection portion 204 of the wireless headset accessory 20, the digital signal processing unit 105 uses a first audio processing algorithm that matches the first sound generating unit 107.
In case the wireless headset is adapted to the headset accessory, the first mating connection 101 is electrically connected to the fifth mating connection 203 of the wireless headset accessory 20 and the second mating connection 102 is electrically connected to the sixth mating connection 204 of the wireless headset accessory 20, the digital signal processing unit 105 uses a second audio processing algorithm matching the second sound generating unit.
In this embodiment of the present application, in a case where the wireless earphone is not adapted to the wireless earphone accessory, the first mating connection portion is not electrically connected to the fifth mating connection portion of the wireless earphone accessory, and the second mating connection portion is not electrically connected to the sixth mating connection portion of the wireless earphone accessory, the path between the digital-to-analog converter and the second sound generating unit is disconnected, and the path between the digital-to-analog converter and the first sound generating unit is turned on. At this time, the micro-processing unit controls the digital signal processing unit to use the first audio processing algorithm matched by the first sound generating unit. In this way, the digital audio file processed by the digital signal processing unit will be better suited for the first sound generating unit. Furthermore, when the first sound generating unit outputs the analog audio file output to the digital-to-analog converter, the optimal hearing feeling can be achieved within the self capacity range value.
Correspondingly, in the embodiment of the application, under the condition that the wireless earphone is matched with the wireless earphone fitting, the first matching connection part is electrically connected with the fifth matching connection part of the wireless earphone fitting, the second matching connection part is electrically connected with the sixth matching connection part of the wireless earphone fitting, the passage between the digital-to-analog converter and the second sounding unit is conducted, and the passage between the digital-to-analog converter and the first sounding unit is disconnected. At this time, the micro-processing unit controls the digital signal processing unit to use a second audio processing algorithm matched with the second sound generating unit. In this way, the digital audio file processed by the digital signal processing unit will be more suitable for the second sound generating unit. Furthermore, when the second sounding unit outputs the analog audio file output to the digital-to-analog converter, the second sounding unit can achieve the optimal hearing feeling within the self capacity range value.
In one example, as shown by the solid line in fig. 3, in the case where the analog audio file output by the digital-to-analog converter 106 is played by the first sound generation unit 107, the bass effect of the first sound generation unit 107 is poor. And as shown by the broken line in fig. 3, since the second sound generating unit 201 is large in volume, it is possible to realize an increase in low frequency at the EQ (equalizer) section. Therefore, in the case where the analog audio file output from the digital-to-analog converter 106 is played by the second sound generating unit 201, the bass effect of the second sound generating unit 201 is good.
In fig. 3, the abscissa indicates frequency and the ordinate indicates gain.
On the basis of any of the above embodiments, as shown in fig. 4, the wireless earphone 10 further includes a first power management module 108 and a first power supply 109, and as shown in fig. 4 and 5, the wireless earphone 10 further includes two other metal mating connection portions, specifically a third mating connection portion 110 and a fourth mating connection portion 111, which are disposed on the housing of the wireless earphone 10. The other two metal mating connection portions may be embodied in the form of gold fingers, or may be embodied in the form of metal contacts, for example.
The third mating connection portion 110 is electrically connected to an input terminal of the first power management module 108 of the wireless headset 10. The fourth mating connection 111 is electrically connected to the ground of the first power management module 108. An output of the first power management module 108 is electrically connected to an input of the first power supply 109.
Wherein, in the case of adapting the wireless headset to the headset accessory, the third mating connection portion 110 is electrically connected to the seventh mating connection portion 206 of the wireless headset accessory 20, the fourth mating connection portion 111 is electrically connected to the eighth mating connection portion 207 of the wireless headset accessory 20, and the second power management module 205 in the wireless headset accessory 20 performs a charging process on the first power management module 108.
Correspondingly, in the case that the audio file wireless headset is not adapted to the audio file wireless headset accessory, the third mating connection portion 110 is not electrically connected to the seventh mating connection portion 206 of the wireless headset accessory 20, the fourth mating connection portion 111 is not electrically connected to the eighth mating connection portion 207 of the wireless headset accessory 20, and the wireless headset 10 operates according to the conventional wireless headset operating method.
In this embodiment, in the case where the user places the wireless headset in the wireless headset accessory, that is, in the case where the wireless headset is fitted with the audio file wireless headset accessory, the third mating connection portion of the wireless headset is electrically connected with the seventh mating connection portion of the wireless headset accessory, and the fourth mating connection portion of the wireless headset is electrically connected with the eighth mating connection portion of the wireless headset accessory. Because the seventh mating connection portion of the wireless headset accessory is the power output end of the second power management module of the wireless headset accessory, and the eighth mating connection portion of the wireless headset accessory is the ground end of the second power management module of the wireless headset accessory, under the condition that the wireless headset is matched with the wireless headset accessory of the audio file, the second power management module of the wireless headset accessory will serve as charging equipment, and the wireless headset will serve as electric equipment. At this time, the second power management module may perform charging processing on the first power management module, thereby implementing charging of the first power in the wireless headset. Thus, although the wireless earphone has a small size, which results in poor cruising ability of the first power supply in the wireless earphone, the wireless earphone accessory can serve as a charging device to charge the first power supply, so that the cruising ability of the first power supply can be improved.
It should be noted that, the second power management module of the wireless earphone accessory includes an LDO (low dropout regulator; low dropout linear regulator), a DCDC step-down circuit, etc., which can control the output current and voltage, so that the second power management module can realize safe charging of the wireless earphone.
On the basis of any of the above embodiments, as shown in fig. 5, the first sound generating unit 107 includes the first operational amplifier 1071 and the first sound generating element 1072. The input terminal of the first operational amplifier 1071 is used as the input terminal of the first sound generating unit 107 and is electrically connected to the second output terminal of the digital-to-analog converter 106. An output of the first operational amplifier 1071 is electrically connected to an input of the first sound generating element 1072.
In the embodiment of the present application, the first operational amplifier 1071 amplifies the analog audio file output by the digital-to-analog converter 106, so that the amplified audio file can push the first sound generating element 1072 to generate sound. Wherein the first sound generating element 1072 is typically a loudspeaker.
In this embodiment, when the micro-processing unit 104 controls the first sound generating unit 107 to be powered down, the specific steps may be: the first operational amplifier 1071 and/or the first sound generating element 1072 in the first sound generating unit 107 is controlled to be powered down. When the first operational amplifier 1071 and the first sound generating element 1072 in the first sound generating unit 107 are controlled to be powered down, the power consumption of the wireless earphone 10 can be reduced.
The embodiment of the application also provides a wireless earphone fitting 20. As shown in fig. 6, the wireless headset accessory 20 includes a second sound generating unit 201, an interrupt circuit 202, a fifth mating connection 203 and a sixth mating connection 204 provided on the housing of the wireless headset accessory 20. The two metal mating connections may be embodied in the form of gold fingers, or in the form of metal contacts, for example.
Wherein the input end of the second sound generating unit 201 is electrically connected with the fifth matching connection part 203; the output of the interrupt circuit 202 is electrically connected to the sixth mating connection 204.
