Description
Technical field
The present invention relates to electronic audio frequency technical field, and in particular to a kind of improved structure of combination earpiece loudspeaker.
Background technology
For mobile phone, usually top receiver, bottom outside speaker；When doing stereosonic, it is typically also top
Receiver, loudspeaker, bottom put a loudspeaker again.Receiver is different with the power of loudspeaker, and loudspeaker power maximum is close to 1 watt, and receiver work(
Rate maximum only 20 milliwatts, as power is different, both can not directly share same loudspeaker, therefore current mobile phone China and foreign countries put
Music, the tinkle of bells is the horn-type loudspeaker that 8 Ω are driven after high-power audio power amplifier during hands-free grade loudspeaker mode of operation, receiver
Pattern is the earpiece speaker that audio decoder drives 32 Ω through low-power audio power amplifier so that take space mistake in mobile phone
Greatly, it is relatively costly, and with consumer for the requirement of handset capability is improved constantly, receiver and loudspeaker are tied in prior art
Close, and be arranged at the top of mobile phone, bottom mainly needs to give battery vacating space.
Although certain progress is achieved with upper type, but it is this by receiver and the two-in-one connection of loudspeaker, easily affect electricity
The function in source, and in user by mobile phone near ear when, be constantly present the excessive problem of sound.
The content of the invention
The technical problem to be solved is will be receiver and loudspeaker two-in-one, is playing the D classes such as music, incoming call jingle bell
When power amplifier works, easily there is the excessive problem of low battery alarm and Headphone volume, it is therefore intended that one kind is provided and combines mobile phone
The improved structure of receiver loudspeaker, solves existing receiver and loudspeaker integrative-structure easily has low battery alarm and Headphone volume
Excessive problem.
The present invention is achieved through the following technical solutions：
A kind of improved structure of combination earpiece loudspeaker, including range sensor, microprocessor, switch switching circuit,
Receiver power amplifier, loudspeaker power amplifier, loudspeaker, wherein, between described range sensor collection mobile phone and face away from
From information, and by distance information transmission to microprocessor；Described microprocessor sends the instruction of switching receiver to switch switching electricity
Road；Described receiver power amplifier sends audio signal to switch switching circuit；Described loudspeaker power amplifier sends audio frequency letter
Number arrive switch switching circuit；Described switch switching circuit receives the audio signal of receiver power amplifier transmission or loudspeaker power amplifier electricity
The audio signal of road transmission, and by audio signal transmission to loudspeaker.Range sensor, microprocessor in the present invention, switch
Switching circuit, receiver power amplifier, loudspeaker power amplifier, loudspeaker are device element commonly used in the prior art, the present invention
Connection is reconfigured simply, to realize new function.Used in prior art, receiver and loudspeaker two are closed by D class audio frequencies power amplifier
The circuit of one connection, as D class power amplifier output amplitudes are fitted on the amplitude on RCV more than VBAT, so the benchmark of AVDD can be affected
The output of voltage, i.e. D classes power amplifier has influence on internal AVDD power supplys by receiver and loudspeaker mixing output circuit, so broadcasting music,
When incoming call jingle bell etc. D classes power amplifier works, easily there is low battery alarm problem, the strong influence performance of mobile phone.Together
When, as earphone portions signal voltage is less than loudspeaker audio frequency power amplifier output voltage, so it is excessive that volume is constantly present when making a phone call
Problem.To solve the above problems, the present invention arranges a switch switching circuit on the integrated connection circuit of receiver and loudspeaker,
It is using receiver or loudspeaker, then by the distance between the mobile phone for collecting and face by range sensor identifying user
Information transfer is processed to microprocessor, microprocessor, when being identified as using receiver, automatically cut off loudspeaker power amplifier with
Passage between loudspeaker, and receiver power amplifier is connected with loudspeaker, the function of receiver is realized with this；When be identified as use
During loudspeaker, the passage between receiver power amplifier and loudspeaker is automatically cut off, and loudspeaker power amplifier is connected with loudspeaker；
By solving the problems, such as to have influence on internal AVDD power supplys with upper type and sound is excessive.
Also include voltage-stabilized power supply circuit, the voltage-stabilized power supply circuit is connected with microprocessor.Further, voltage-stabilized power supply electricity
Road is connected with microprocessor, for system power supply, and has been effectively isolated interference of the electrical network to audio frequency apparatus.
The present invention compared with prior art, has the following advantages and advantages：
A kind of improved structure of combination earpiece loudspeaker of the present invention, is arranged on the integrated connection circuit of receiver and loudspeaker
One switch switching circuit, is using receiver or loudspeaker, then by the hand for collecting by range sensor identifying user
To microprocessor, microprocessor is processed the distance between machine and face information transfer, when being identified as using receiver, automatically
Passage between cut-out loudspeaker power amplifier and loudspeaker, and receiver power amplifier is connected with loudspeaker, receiver is realized with this
Function；When being identified as using loudspeaker, the passage between receiver power amplifier and loudspeaker is automatically cut off, and by loudspeaker work(
Electric discharge road is connected with loudspeaker；By solving the problems, such as to have influence on internal AVDD power supplys with upper type and sound is excessive.
